In their own words
Composer AI
Composer AI is an email drafting tool for Gmail that uses an email thread and the user’s tone to prepare replies. Users connect Gmail, open a message, review and edit the generated draft, then send it. The homepage states that replies are produced in under three seconds. Composer AI is available on the web and as a browser extension, using Google APIs to read Gmail threads during composition. Its Free Beta Tier costs nothing and includes 20 draft compositions per account; users may request a manual limit increase. The privacy policy says thread content and prompts are sent to OpenAI, retained for up to 30 days, and not used for model training. Full conversation and email content is logged to LangSmith for debugging and service improvement, with deletion after 14 days. The service is experimental beta software without service-level agreements or uptime guarantees and advises against highly sensitive communications.
