Revise
Revise is a browser-based AI document editor and word processor, offered through web, API, and self-hosted options. Its AI agent can brainstorm, draft, edit, rewrite, and search the web for citations, presenting proposed changes for review.

Revise supports models from OpenAI, Anthropic, Google, and xAI, plus real-time collaboration and focused document comment threads. ChatGPT and Claude plugins use the customer’s subscriptions, while an SDK connects external agents through MCP. Documents and AI conversations are described as private by default, encrypted in transit and at rest, and deletable by the user. The Free plan costs $0 per month and includes a daily AI limit.
