Revise is an online word processor with a built-in AI agent that can draft, research, proofread, and edit alongside the user. It lets people work on documents with AI inside a full writing environment, asking for changes, reviewing them in-line, and keeping control over what gets accepted. Revise is designed to feel like a familiar document editor, with rich formatting, tables, images, insert tools, find, dictation, export, sharing, and real-time collaboration, while adding an AI agent directly into the writing flow. It can act as a proofreader, writing assistant, researcher, editor, and document collaborator, helping users revise text without copying content into a separate chatbot. Revise supports leading AI models in one place, including GPT, Claude, Grok, and Gemini, so users can switch between models depending on the task. Its word processor includes an LLM-powered spellcheck that works while users type and catches subtle mistakes traditional spellcheckers may miss.
