Revise

Revise is a free online document editor with a built-in AI agent. Write, edit, and format documents with the help of GPT, Claude, Gemini, and Grok. Every AI edit is shown as a reviewable suggestion, so you stay in control and can accept or reject each change.

It supports DOCX formatting, tables, images, and page layout, and keeps a full revision history so you can roll back to any earlier draft if an edit goes sideways. One handy feature is the ability to switch between several AI models (from OpenAI, Anthropic, Google, and xAI) mid-project, so it’s worth testing a couple on the same document to see which tone fits your writing best.
