Compose AI is a free Chrome extension that autocompletes your writing anywhere on the web, rephrases text, and drafts email replies using AI.
Compose AI is a free, Y Combinator-backed Chrome extension that adds AI-powered autocomplete to any website. Instead of a standalone editor, it works inline wherever a user types — in Gmail, Google Docs, LinkedIn, or internal web tools.
The product has been publicly available since around 2020 and reports being used by more than 10,000 teams and roughly 400,000 individual users.
The core feature is inline autocomplete, triggered either by typing "//" followed by an instruction, or simply by accepting suggested completions as you type. A rephrasing tool can adjust selected text to sound friendlier, more professional, shorter, or longer.
An email-specific mode can generate a full draft reply from a short phrase, and a personalization layer learns an individual's writing style over time to make suggestions feel less generic.
Compose AI is free to use indefinitely for its core autocomplete and rephrasing features, with no credit card required. A premium tier adds expanded personalization and additional advanced features; the exact premium price is not disclosed on the public marketing site.

Type "//" followed by an instruction to generate text with AI, or simply keep typing and accept the inline suggestions it offers.
It's designed for professionals who type a high volume of email, messages, or web-based content and want faster, lighter-weight autocomplete than a full AI writing suite.
