Office work: ChatGPT Work, Copilot, Gemini

  1. ChatGPT Work — uses your apps, files, tools and browser to produce docs, decks, spreadsheets and sites, schedules recurring work, and its Plan mode shows the steps first. Included with Plus ($20/mo, monthly only). Our ChatGPT Work guide.
  2. Microsoft 365 Copilot — Microsoft 365 Premium ($19.99/mo) adds “limited usage for agentic AI that gets things done for you” inside Word, Excel, PowerPoint and Outlook; Microsoft 365 Pro ($99.99/mo) has the highest agentic usage. Best if your work lives in Office files.
  3. Google Gemini — AI Pro ($19.99/mo) includes Chrome auto browse, the Jules coding agent and Antigravity. Best for Gmail, Docs and Chrome users.

New on 21 October 2026: Anthropic opened a waitlist research preview of Claude Duet, a proactive agent app that sends a morning brief and works on its own cloud computer, for US Claude Pro and Max subscribers. See our Claude Duet guide.

Coding: Claude Code, Codex, Jules

  1. Claude Code — works in the terminal, IDE, desktop app and web; reads your codebase, edits files and runs commands, with a computer-use preview. Included from Claude Pro ($20/mo, or $17/mo billed annually). Our Claude Code guide.
  2. OpenAI Codex — OpenAI’s coding agent, included in ChatGPT plans. A natural pick if you already pay for ChatGPT.
  3. Google Jules — the coding agent included in Google AI Pro ($19.99/mo), alongside Antigravity.

Whichever you choose, give it an instruction file: an AGENTS.md or CLAUDE.md with your build and test commands makes every run more reliable. Our generator writes one in a minute.

Browser tasks: Comet, Gemini in Chrome, Claude in Chrome

  1. Perplexity Comet — a free AI browser for Mac, Windows, iOS and Android; its Comet Assistant handles email, shopping, forms and multi-step web tasks. Browser-agent queries need Pro (monthly limits) or Max ($200/mo). Our Comet guide.
  2. Gemini auto browse — Gemini completes tasks in Chrome; included in Google AI Pro, with the highest access on AI Ultra.
  3. Claude in Chrome — included from Claude Pro, together with handing off and scheduling tasks.

Free to try: Manus, ChatGPT Work, Copilot

  1. Manus — free accounts get 300 refresh credits every day, enough to run a real research or slide task; Pro starts at $20/mo. Our Manus guide.
  2. ChatGPT Work — Free users get limited access in the desktop app.
  3. Microsoft Copilot — the free Copilot works with usage limits.

Mainland China: Doubao Work, Qwen, Kimi
