Use tool ↗About Compose AI
Compose AI is a Chrome extension that autocompletes sentences as you type and drafts text on request in Gmail, Google Docs and most text fields on the web. Typing two slashes asks the AI to write something from a short instruction, and separate commands rephrase, shorten or expand a passage or draft a full email reply in one click. It learns a user's phrasing over time to personalise suggestions. The basic extension is free with monthly caps, and Premium and Ultimate subscriptions raise or remove those caps; the Chrome Web Store listing shows about 300,000 users and an update in October 2026.

Pros & cons of Compose AI
A low-friction way to speed up routine email and doc writing: the free tier installs in a minute and completes sentences anywhere in Chrome. The extension is still being updated, but its free caps are small and browser-native AI features now cover much of the same ground at no cost, so the paid tiers have to earn their place.
Pros
- Basic extension is free with no time limit
- Autocomplete works across most web text fields, not one app
- Learns personal writing style for suggestions
- Annual billing cuts the Premium price by a third
Cons
- Chrome-only, with no public API or desktop apps found
- Free plan caps AI writing at 1,500 words a month
- Marketing site copy and copyright are still dated 2024, which makes the product look less maintained than its store listing suggests
Best for
- Heavy email writers who churn out routine replies in Gmail
- Non-native English speakers who want inline phrasing help
- Anyone testing writing autocomplete without paying
Not for
- Long-form or brand-voice content work
- Firefox, Safari or non-browser workflows
Watch out: The headline $9.99 is the annual rate; paying month to month costs $14.99, and Gmail, Docs and ChatGPT now bundle similar completion for free, so try the free tier before committing a year.
