AI autocomplete for Gmail and Google Docs
About Compose AI
Compose AI is a Chrome extension that adds AI-powered writing assistance directly into any web-based text field, with particular strength in Gmail and Google Docs. It provides real-time autocomplete suggestions as users type, allowing them to accept, modify, or ignore AI-generated continuations with a single keystroke. Compose AI learns from individual writing patterns over time, producing suggestions that increasingly match the user's personal tone and vocabulary. Beyond autocomplete, it includes a full sentence and paragraph generation feature triggered by a simple slash command, allowing users to generate complete email replies, document sections, and messages from brief prompts. The core autocomplete feature is free with no word limits, making it one of the most accessible AI writing tools available.
