Revise

What it does

Revise is a browser-based document editor that lets users import Word files, PDFs, and Markdown documents, then edit them with AI assistance. The tool integrates with GPT, Claude, Gemini, and Grok models. Users can make edits manually or request AI agents to rewrite sections based on prompts. All changes from AI appear as tracked suggestions that users accept or reject individually. The editor preserves formatting, comments, and page layouts from imported documents.

Who it is for

Revise targets users who edit documents regularly and want AI assistance without leaving their current workflow. The tool suits professionals handling documentation tasks, including writers, developers, and therapists. It also serves teams where people and AI collaborate on the same document in real time. Users can leverage their existing AI subscriptions through the editor instead of copying text between applications.

Pricing

Revise offers a free tier with no credit card required. The site does not show prices for premium features or paid plans.

How it stands out

The word processor engine and rendering layer were built from scratch rather than using existing document frameworks, with Y.js as the only third-party library for the CRDT synchronization stack. This custom architecture enables real-time collaboration between humans and AI agents. The tool also supports Model Context Protocol, allowing users to connect it to Claude and other compatible AI applications from their existing workflows. Tracked changes preserve edit history with individual approval controls, preventing users from losing context about what changed and why.

What a founder should check

First, examine how incumbent document editors like Google Docs, Microsoft 365, and Notion are adding AI features. These platforms have massive user bases, existing integrations, and native AI capabilities built into their products. Second, investigate switching costs for users already invested in document management systems, folder structures, and permissions within existing platforms. Third, verify whether Revise's advantage of using your own AI subscriptions remains viable as major productivity suites bundle AI access more tightly and make it cheaper than separate subscriptions elsewhere.
