Revise

Revise is a free, browser-based word processor with an AI agent built into the editing surface rather than bolted on as a chat sidebar. You import or write a document, then describe the task — proofread this, reconcile these two drafts, incorporate the reviewer comments, tighten the executive summary — and the agent produces tracked changes you review one by one. Because nothing is applied silently, you keep authorship over the final text, which is the main reason writers use it instead of pasting prose into a chatbot.

Under the hood it is a genuine document editor. DOCX, PDF, RTF, ODT, Markdown, and plain text files open with their formatting, comments, and tracked revisions preserved, and PDFs are handled by a vision model so scans and photocopies are rebuilt with their tables, footnotes, and page headers. Sharing works like a collaborative word processor: multiple people can edit at once and see each other's cursors, with comments and suggestions syncing in real time.

Revise is also unusually open about model choice. Several frontier models are available in one editor, and the free ChatGPT and Claude plugins let the agent operate inside the apps many people already pay for, using their own subscriptions. Teams with their own agent infrastructure can connect over MCP instead. The company reports over a million AI edits accepted since launch and prices a generous free tier alongside monthly subscriptions for heavier use.
