Building apps & websites ("vibe coding")

ClaudeArtifacts + Claude Code + Design
free

Build apps, sites, and even Chrome extensions in natural language; Artifacts render and run live in the chat.

ChatGPTSites / Canvas
needs paid plan

Describe a site or app and it builds, hosts, and publishes it at a shareable URL, with versioning and access controls. Public beta on paid plans; not on the free or entry tiers.

GeminiCanvas
free

Turns prompts into working apps, games, infographics, quizzes, and web pages you can refine and export.

PerplexityLabs
needs paid plan

Labs can spin up mini-apps and dashboards from research, but it isn't built for real coding work.

DeepSeekCoding in chat
free

Writes and debugs code well in the conversation, but there's no live build-and-preview surface — you copy the code out to run it.

KimiOK Computer
needs paid plan

An agent mode that builds multi-page websites and editable slide decks from a prompt; capable but still beta and best for first drafts.

GrokBuild Mode
free

Describe a website, app, game, or dashboard and Grok builds a working preview in the chat, then publishes it to a grok.me link or your own domain. Still labeled early beta; output quality reported as uneven.

ManusWeb app builder
free

Builds and hosts working sites and apps from a prompt, with one-click publishing to web, iOS and Android. A separate Game Dev environment builds playable, shareable games, including multiplayer ones.

MuseRunnable apps
free

Creates runnable apps as artifacts. It can also pass work to an app-building tool through a connector (Lovable is on the connector list).

Creating downloadable files (Excel, Word, PPT, PDF)

ClaudeFile creation
free

Builds real .xlsx, .pptx, .docx, and PDF files from a chat, with formulas and formatting — free for all users, 30MB per file.

ChatGPTData analysis / export
needs paid plan

Generates spreadsheets and files via its data-analysis engine, plus a Microsoft add-in covering Word, Excel, and PowerPoint that is available on all plans including free; strongest for code-related exports.

GeminiFile creation
free

Creates Docs, Sheets, Slides, and PDFs directly in chat, free for all users since April 2026.

PerplexityLabs deliverables
needs paid plan

Labs turns research into slides, spreadsheets, and dashboards, but it's a Pro/Max feature, not a general file maker.

Microsoft CopilotOffice file generation
needs paid plan

Generates Word/Excel/PowerPoint natively — it lives in Office — and Notebooks can build a full deck; needs a paid Office/Copilot plan.

KimiSlides / Sheets / docs
needs paid plan

Generates slide decks, spreadsheets, and documents exportable to Office formats through its Work tools on paid tiers.

GrokSkills (Word, Presentations, Spreadsheets, PDFs)
free

Built-in Skills generate formatted .docx, .pptx, .xlsx, and PDF files, and can restructure files you upload. Included with every account.

free

Creates PDFs, DOCX, TXT, Markdown, XLSX, CSV, PNG, JPEG, GIF, WebP, code files, browser-viewable web tools, audio, and podcasts, saved to the Library tab.

Custom assistants

ClaudeProjects + Skills
free

Set instructions and upload files per project; Skills and Plugins add packaged capabilities. Free users get up to 5 projects.

ChatGPTCustom GPTs
needs paid plan

A large ecosystem via the GPT Store. Build with instructions, knowledge files, and actions. Browsing is free; building needs a paid plan.

GeminiGems
free

Custom personas with instructions and uploaded files, now free to create and shareable via Drive links. They plug into Workspace apps like Docs and Gmail.

PerplexitySpaces
needs paid plan

More a research workspace with custom instructions and files than a shareable bot. File uploads require a Pro plan.

Microsoft CopilotAgents / Copilot Studio
needs paid plan

The consumer app has almost no bot-builder. Real customization lives in Copilot Studio, which is enterprise, low-code, and separately priced.

KimiKimi+ agents
free

A marketplace of pre-built specialized agents (academic writing, coding, presentations) plus 'Document-to-Skills' for turning documents into reusable skills; less a from-scratch bot builder.

GrokCustom Skills
free

Save reusable instructions, formats, and reference files as a Skill that Grok applies in any chat; build one by describing it or with the built-in Skill Creator. There is no standalone, shareable assistant with its own chat page; named persistent assistants live only in the separate Grok Bot app. Available on Free; paid plans add usage headroom.

ManusProjects + Skills
free

No standalone assistant builder. Projects apply reusable instructions and knowledge files to every new task, while Skills add reusable capabilities. Manus's separate Cue app creates personal agents but sits outside this product.

Project workspaces

ClaudeProjects
free

Persistent workspaces with files, custom instructions, and project memory. Available even on the free tier (up to 5).

ChatGPTProjects
needs paid plan

Groups related chats, files, and instructions under one project.

GeminiNotebooks / Gems
free

PerplexitySpaces
needs paid plan

Purpose-built for this, with team collaboration and unified search across your files and the web.

Microsoft CopilotNotebooks
needs paid plan

Copilot Notebooks are emerging but thin on the consumer side compared with the others.

KimiProjects
free

Persistent workspaces that hold reference files, project instructions, and related chats, with context carried into every chat started inside them. Quotas scale by plan, starting at 2 projects and 500MB of storage. The Kimi Work desktop app has its own separate projects that don't share data with these.

GrokProjects
free

Group chats, uploaded files, and custom instructions by topic so every chat in the project references them. Available on Free; paid plans add usage headroom. Some users have reported Projects missing when using grok.x.ai instead of grok.com.

ManusProjects
free

Projects hold a master instruction plus a knowledge base of files that every new task inherits. On Team plans, members of a shared Project see only the tasks they created.

Live document / canvas editing

ClaudeArtifacts + Docs & Slides
free

Generates documents, pages, charts, and interactive pieces you can iterate on live. Docs and Slides, added September 2026, add in-place editing, comments, and export to PowerPoint or PDF; both are in beta on paid plans.

ChatGPTCanvas
needs paid plan

Still there for writing and code, but folded back into the main chat window on the newest models.

GeminiCanvas
free

A dedicated space to draft and refine documents or code, exportable to Google Docs.

PerplexityPages
needs paid plan

Turns research into shareable published pages; more about publishing than collaborative editing.

Microsoft CopilotPages
free

Collaborative Copilot Pages for building and refining content with suggested edits.

KimiSlides editor
needs paid plan

Generates editable slide decks with an in-browser editor, though the editor is basic and you'll often export to PowerPoint for final polish.

ManusManus Studio
free

The desktop workspace lets you edit what Manus made (docs, slides, sites, video timelines, game assets) by hand and hand it back. It's an editing environment more than live co-writing. On the free plan it's available but limited by the credit cap.

Agent that builds deliverables in a cloud workspace

unique to Kimi
KimiOK Computer
needs paid plan

An agent mode that plans a task, runs searches and code in its own cloud workspace, and hands back a finished artifact — a slide deck, a small web app, a dashboard, or a report — rather than just text in the chat. The free plan includes a small monthly allowance of agent tasks; sustained use needs a paid tier.

Build and publish playable games

unique to Manus
ManusGame Dev
free

An environment for building browser games you can edit by hand, publish as a link, and run in multiplayer on a Cloud Computer.

Run the agent on your own model key

unique to Manus
ManusManus Flex
free

Connects your own API key from OpenRouter, Fireworks or Modal so a model you choose runs inside Manus. Available on the free plan; the provider bills inference, and Manus credits still cover tools and infrastructure.

Shareable mini-apps

unique to Claude
ClaudePublished Artifacts
free

Artifacts can be published as interactive mini-apps others use without a Claude account — a sharing model the others don't offer.

Research · 8

Live web & browsing

ClaudeWeb search
free

Searches the web when needed, but the web isn't the center of the product.

ChatGPTSearch
free

Web results with source links folded into a general assistant.

GeminiGoogle Search grounding
free

Answers grounded in Google Search, which helps on factual, up-to-date questions.

PerplexityComet / answer engine
free

Its whole identity: citation-first answers, and now a full AI browser that's free across platforms.

Microsoft CopilotEdge / Copilot Vision
free

Built into Edge and can look at what's on your screen or camera to help in context.

DeepSeekWeb search
free

Searches the live web for current questions, but citations are lighter and there's no browser.

KimiWeb search
free

Web search and browsing are core and free; on paid tiers the WebBridge agent actively navigates sites for you.

GrokReal-time web + X search
free

Pulls live web results and live posts from X into answers. There is no Grok-branded AI browser; web and X search are limited on the free plan.

ManusCloud Browser / Browser Operator
free

Works in a Manus-hosted browser that keeps you signed in, or through an extension in your own Chrome or Edge. Hosted browsing often hits CAPTCHAs that need you to take over.

MuseMuse Secure VM browser
free

Each user's agent has its own browser in an isolated cloud machine. A separate gatekeeper called Sentinel approves outbound actions and asks you before anything sensitive.

Deep research

ClaudeResearch
needs paid plan

Multi-source research with citations, plus connectors to pull from your own tools.

ChatGPTDeep Research
needs paid plan

Produces long, well-structured, cited reports at roughly junior-analyst quality.

free

Fast, citation-dense, one-click source verification. Labs can output slides, sheets, and dashboards directly.

needs paid plan

Consumer Deep Research was removed in the August 2026 Copilot app merger; its replacement, Researcher, produces multi-source cited reports but is limited to paid Microsoft 365 Premium.

KimiDeep Research
needs paid plan

Researches across sources and produces briefs and slides, though it can occasionally cite sources that don't exist — verify before relying on it.

GrokDeepSearch
free

A dedicated mode that runs multi-step searches across the web and live X posts and returns a cited report. It can appear on Free, but Free's search allowance is limited; once you hit the cap, it pauses or falls back to regular chat. Sources can mix social posts with published reporting, and independent tests have found citations that don't match the linked source, so check key claims.

ManusWide Research
needs paid plan

Splits a large research job across many sub-agents that run in parallel and compiles the results into a document or spreadsheet. Sites that block automated browsing can leave gaps.

MuseResearch skill
free

Researches on the web and in connected apps when a task needs it, and cites sources if asked. There is no dedicated report mode.

Citations to the exact spot in a file

unique to Microsoft Copilot
Microsoft CopilotDeep citations
needs paid plan

Citations that link directly to the specific section of a referenced file — pre-scrolled to the relevant passage — instead of just naming the file, making it much faster to verify Copilot's answers against the source.

Compare several models at once

unique to Perplexity
PerplexityModel Council
needs paid plan

Runs one question through several leading models from different vendors simultaneously, shows the answers side by side, and synthesizes them — with a separate pass flagging where they agree and diverge. No other major assistant has native multi-model comparison built in.

Financial research terminal

unique to Perplexity
PerplexityPerplexity Finance
needs paid plan

A dedicated finance hub — live earnings-call transcripts, SEC filing analysis, market heatmaps, portfolio analytics, and price alerts. No equivalent in the other four.

Full visible reasoning trace

unique to DeepSeek
DeepSeekDeepThink chain of thought
free

Prints its raw step-by-step reasoning in full rather than a cleaned-up summary, free with no separate tier. Claude and Kimi also expose their thinking, but DeepSeek's trace is the least filtered.

Live social-media search

unique to Grok
GrokReal-time X Search
free

Grok searches live posts on X alongside the web, so answers can reflect what people are posting right now, not just published articles. Social posts can be unverified, so treat them as signal rather than fact.

Paywalled journalism inside the browser

unique to Perplexity
PerplexityComet Plus
needs paid plan

A roughly $5/month add-on (also bundled into Pro and Max) that unlocks premium content from partner publishers like CNN, The Washington Post, and Le Monde directly inside answers and the Comet browser, with most of that revenue shared back to the publishers.

free

Native, high-quality image creation and editing inside the chat.

Microsoft CopilotDesigner / Imagine
free

KimiSlides imagery
needs paid plan

No standalone image generation in chat, but the Slides tool generates per-slide imagery through an integrated third-party model.

MuseMuse Image
free

Generates images with Muse Image when a task calls for one.

Video generation

GrokGrok Imagine
needs paid plan

Generates short video clips with native audio from text or images. Resolution is tier-gated: 480p on the entry plan, 720p on SuperGrok, 1080p on SuperGrok Plus and up; 720p requests fall back to 480p once you hit your cap.

ManusVideo Editor
free

Makes short videos (ads, tutorials, vlogs) and hands back an editable timeline, so you can swap clips or music without regenerating everything. Alchemy mode takes on creative direction. Available on the free plan, though restricted by credit caps.

Podcast-style summaries

unique to Gemini
GeminiAudio Overviews
free

Turns uploaded documents into a 'podcast-style' two-host audio discussion, via Gemini Notebook inside Gemini.

Actions · 17

Scheduled & recurring tasks

ClaudeScheduled Tasks
needs paid plan

Save a prompt to run on a recurring cadence.

ChatGPTTasks
free

Schedules recurring prompts like reminders and briefings — useful, but closer to a reminder tool than a full agent. Free accounts get up to three active tasks, running no more than once a day.

GeminiScheduled Actions
needs paid plan

Runs recurring prompts, strongest when the task lives inside Google Workspace.

PerplexityScheduled searches
needs paid plan

Recurring searches and research tasks that run on their own; heavier automation sits on the top tiers.

Microsoft CopilotAgent flows / Cowork
needs paid plan

Recurring automation runs through agent flows and Cowork rather than a simple saved-prompt scheduler; enterprise-oriented.

KimiScheduled tasks
free

Saved prompts that run on a recurring schedule, with a per-plan quota starting at 2 on the free tier. Schedules set in the Kimi Work desktop app run locally, so they don't fire while the machine is asleep or the app is closed.

GrokAutomations
free

Save a prompt to run once, daily, weekdays, weekly, monthly, or yearly. It can also run when a matching email arrives, but that trigger needs SuperGrok.

ManusScheduled Tasks / Automations
free

Runs on a schedule, and since Manus 2.0 can also start on events in connected services (new email, calendar event, Slack message, Notion update). Free accounts are limited to 2 scheduled tasks; advanced Automations are in beta.

MuseUpcoming
free

Keeps working in the background and lists reminders and scheduled tasks in an Upcoming view. Recurring scheduled tasks are limited and mostly arrive as reminders in chat.

Taking actions for you (agents)

ClaudeCowork / Computer Use
needs paid plan

Opens files, organizes folders, drafts emails, and builds docs, and can run scheduled recurring tasks. Since September 2026 this runs from any conversation rather than a separate Cowork surface, rolling out on paid plans first.

ChatGPTWork / Agent
needs paid plan

Its Work agent runs longer tasks across connected apps and files in a hosted browser, including on sites that require you to sign in, and pauses for approval on consequential actions.

GeminiAgent Mode / Project Mariner
needs paid plan

Agentic task automation, largely on the top tier and still rolling out.

PerplexityComet
free

Its AI browser clicks, fills forms, and runs multi-step tasks across tabs. Being agentic, it asks you to confirm sensitive actions.

Microsoft CopilotAgentic mode / Copilot Actions
needs paid plan

Generally available inside Word, Excel, and PowerPoint since April 2026, and strong at acting on your Microsoft 365 content.

KimiOK Computer / Agent Swarm
needs paid plan

A standout: runs autonomous multi-step tasks and coordinates many sub-agents in parallel for research and coding. Behind paid tiers, and still maturing.

GrokGrok Bot
needs paid plan

Named AI teammates that each work on a persistent cloud computer, sign into sites and apps with your credentials, keep running when your device is closed, and hand work to each other. A separate app from grok.com, still in beta; all of your Bots share one computer, so xAI says not to treat separate Bots as a security boundary.

ManusManus (Cloud Computer / My Computer)
free

The core product. It works in a cloud sandbox, in your own Chrome or Edge browser, or on your own desktop, and can be controlled remotely from your phone. Long tasks can fail partway and still use credits.

MuseMuse
free

The core product. It browses, fills forms, books, negotiates and checks out on your behalf in a dedicated cloud machine, and the Mac app can operate desktop apps. It asks before sending or spending.

Connecting to your other tools

ClaudeConnectors (MCP)
free

50+ integrations via an open standard, free on all plans including free.

ChatGPTConnectors / Apps
needs paid plan

Connects to a growing set of apps for reading and limited actions.

KimiWebBridge / MCP
needs paid plan

Strong tool-use under the hood and a browser extension (WebBridge) that operates the web for you on paid tiers; a consumer connector suite for email and calendar is less established.

GrokConnectors
free

Read and act on Google Workspace, Microsoft 365 (Outlook, OneDrive, SharePoint, Teams), Notion, GitHub, Linear, Slack, Salesforce, and more, plus custom MCP servers. Write access means Grok can draft or send on your behalf, so review permissions.

ManusConnectors (MCP)
free

Connects to Gmail, Google Drive, Notion, Slack, GitHub, Stripe, HubSpot and more, plus custom MCP servers. You can also start tasks by emailing Mail Manus or messaging it in Slack. Every connector is on the free plan, but limited credit caps can make heavy use difficult.

MuseConnectors
free

Built-in connectors cover email, calendar, shopping, finance, health and many business tools. Muse can build a Custom Connector for anything else, though Meta doesn't review custom ones.

Send a task to your desktop from your phone

ClaudeDispatch (Claude Code)
needs paid plan

Relays a task from the Claude mobile app to a local Claude Code session on your desktop, where it runs locally with your files, connectors, and tools, then sends the result back to your phone. A relay, not cloud compute — your machine has to be awake. Launched March 2026.

ManusRemote Control
free

Ask Manus from your phone to work on your own computer and watch the desktop live while it does. Equivalent to Dispatch in Claude Code.

Agent builds its own app connection

unique to Muse
MuseCustom Connector
free

Ask Muse to connect a service that isn't on the list; it builds the integration from an MCP server URL or API docs and saves it. Meta doesn't review these.

Agent learns by watching you

unique to Grok
GrokTeach a Task
needs paid plan

In Grok Bot, walk a Bot through a multi-step workflow once and it saves the steps as a reusable skill it can rerun on demand or on a schedule.

Agent pays for things on your behalf

unique to Muse
MuseAgent checkout with Link
free

Muse pays using one-time cards from Stripe's Link wallet, so your real card stays hidden, and eligible purchases are covered by Link's purchase protections.

Agentic assistant across many apps

unique to Perplexity
PerplexityPerplexity Computer
needs paid plan

A top-tier agent that runs multi-step workflows from a single prompt — booking travel, auditing documents, adjusting ad spend — routing each step to whichever of ~19 models fits best and connecting to 400+ apps. It can spin up subagents to work parts of a task in parallel.

Always-on machine for your agent

unique to Manus
ManusCloud Computer
needs paid plan

A paid, always-on cloud machine that keeps automations, hosted apps and multiplayer game servers running when your laptop is closed.

Control Claude via Telegram, Discord, or iMessage

unique to Claude
ClaudeChannels (Claude Code)
needs paid plan

A research preview that lets you message a running Claude Code session through Telegram, Discord, or iMessage, like texting a colleague who's doing the work — no third-party tooling needed.

Coordinated teams of agents

needs paid plan

Grok Bot lets several named Bots run in parallel, message each other in group chats, and pass tasks between them, including a coordinating 'chief of staff' Bot that routes work to specialist Bots.

Email a task to your agent

unique to Manus
ManusMail Manus
free

Forward or send an email to your Manus address and it starts a task from the message.

Marketplace of ready-made agents

unique to Grok
GrokGrok Bot Marketplace
needs paid plan

A public directory of pre-configured Bot templates for roles like research, SEO, sales, and recruiting that you can copy and adapt instead of setting up a Bot from scratch. Comparable in spirit to ChatGPT's GPT Store, but for agents.

Private cloud computer for your agent

unique to Muse
MuseMuse Secure VM
free

Each user's agent and data live in their own isolated cloud machine, with stored credentials Muse can use but can't see. Meta still has access until its announced Confidential VM ships.

Role-specific agents out of the box

unique to Microsoft Copilot
Microsoft CopilotResearcher / Analyst / Facilitator agents
needs paid plan

Named specialist agents that ship ready to use: Researcher runs multi-step scoped research into cited briefings, Analyst does real numerical work in Python across your files, and Facilitator handles meeting notes and coordination — role-agents built in rather than something you configure.

Steer a running session remotely

unique to Claude
ClaudeRemote Control (Claude Code)
needs paid plan

Drives a local Claude Code session: jump into a session already running on another machine, watch it work in real time, and send follow-up prompts to redirect a long-running task — from your phone. Distinct from Dispatch: it steers a live task rather than starting a new one.

Watchdog that approves agent actions

unique to Muse
MuseSentinel
free

A separate supervising agent that must approve anything Muse sends to the internet, and asks you before sensitive actions.

Everyday · 16

GeminiNative multimodal
free

Microsoft CopilotCopilot Vision
free

DeepSeekImage & file analysis
free

Reads uploaded images, screenshots, and documents including long PDFs and spreadsheets, but can't take audio or video as input.

ClaudeMemory
free

Account-level memory carries preferences and working style across sessions when turned on.

ChatGPTMemory
free

Robust, user-configurable memory across chats.

GeminiPersonalization

free

Records preferences and details as you talk and carries them into later chats; capped at 50 saved entries of 500 characters each, viewable and editable in settings.

Choosing the underlying model

ChatGPTModel picker
free

Choose among OpenAI models only; naming (Instant / Thinking / Pro variants) is confusing.

free

Choose among Google's models only.

PerplexityModel selector
needs paid plan

Unusually, you can route to models from OpenAI, Anthropic, and Google under one subscription.

free

Switch between instant and thinking modes and among Kimi's own models — no cross-vendor choice.

GrokMode picker (Auto / Fast / Expert / Heavy)
needs paid plan

You pick a speed-versus-depth mode rather than a named model; Auto routes between Fast and Expert. Expert needs a paid plan and Heavy needs the top tier.

ManusAgent modes / Manus Flex
free

Manus picks the model. You choose a lighter, standard or Max mode. Manus Flex lets you bring your own API key and model from OpenRouter, Fireworks or Modal; the provider bills inference and Manus credits still apply.

free

Completes the purchase inside the chat via PayPal across thousands of merchants, without leaving the conversation.

free

A comparable step-by-step tutoring mode, less developed than Gemini's and not tied to classroom tools.

unique to Gemini
GeminiPersonal Intelligence
free

An opt-in setting that lets Gemini draw on your Gmail, Photos, Search, and YouTube to tailor answers — finding a bag that matches shoes from a recent order, or pulling an appliance's model number off a receipt in your inbox. Off by default; the deepest personal-data integration of the group.

Pick the assistant's personality

unique to ChatGPT
ChatGPTPersonality selection
free

Choose from several preset personalities (alongside the default) that shift ChatGPT's tone and manner across all your chats — a lightweight way to set the vibe without writing custom instructions.

Record and summarize meetings

ChatGPTRecord Mode
needs paid plan

An on-device mode that captures and summarizes a spoken meeting or conversation. Gemini and Copilot also record meetings, though ChatGPT's is among the more platform-agnostic.

Self-maintaining memory

unique to Claude
ClaudeAutoDream (Claude Code)
needs paid plan

A Claude Code memory feature in research preview (not a general Claude.ai feature): a background cycle that tends its memory on its own — reviewing saved notes, resolving contradictions, pruning stale entries, and merging duplicates so the memory stays compact and accurate over time.

Side questions that don't clutter the thread

unique to Claude
Claude/btw (Claude Code)
needs paid plan

A Claude Code slash command that opens a side question — it can see the full session context, but its answer never enters the main conversation history, so you can ask an aside without derailing the thread.
