Free Chrome extension that autocompletes sentences and email replies as you type across the web
Compose AI is a Chrome extension that autocompletes sentences and drafts replies in Gmail, Google Docs and most text fields on the web, learning individual phrasing over time. The basic extension is free indefinitely, with Premium and Ultimate subscriptions lifting monthly word caps and adding personalization; we could not read exact prices from the official pricing page during this check. The Y Combinator-backed company claims 400,000 users, but the site's copyright notice still reads 2024, which points to slow recent development.
Homepage states the basic plugin is free to use forever with paid tiers for advanced personalization. The official pricing page would not render for our fetcher, so exact tier prices are unverified here; third-party listings commonly cite roughly $9.99/month Premium and $29.99/month Ultimate.
Use tool ↗A low-friction way to speed up routine email and doc writing, since the free tier installs in a minute and completes sentences anywhere in Chrome. The catch is stagnation risk: the site's own copyright is frozen at 2024 and browser-native AI features increasingly do the same job for nothing.
Watch out: Verify the extension is still actively maintained before subscribing — the marketing site shows 2024-era copy and Gmail, Chrome and ChatGPT now bundle similar completion features free.
