What Compose AI is
Compose AI predicts and generates text inside supported websites, with shortcuts for drafting and rewriting. It aims to reduce keystrokes rather than provide a research or fact-checking environment.
Feature coverage
- Inline autocomplete
- Draft generation shortcuts
- Sentence rewriting
What stands out
- Focused, low-friction workflow
- Useful for repetitive messages
- Substantial public install base
Tradeoffs to know
- Store update is more than a year old
- Only 244 ratings
- Autocomplete is not a substitute for source checking
Permissions and privacy
Page access
Browser AI assistants may read the active page and selected text to generate a response. Check the current host permissions and avoid submitting private course, client, or account data.
Data notes
AI features may send prompts and page context to remote models. Treat the developer policy, model-provider terms, retention settings, and school or workplace rules as part of the product decision.
Pricing
Free core product with paid Premium features. Pricing and plan limits change more often than store metadata, so use the linked developer page as the final check before subscribing.
