Composer AI

What Composer AI is

Composer AI is an email composition tool that prepares reply drafts from a Gmail conversation and aims to match the user’s tone. To use it, connect Gmail, open a message, review and edit the proposed draft, then send it. The service uses Google APIs to read Gmail threads when composing replies, and its homepage says it produces thoughtful replies in under 3 seconds. Composer AI is available on the web and as a browser extension. Its Free Beta Tier costs nothing and provides 20 draft compositions per account; users can contact the operator to request a manual increase. Composer AI describes itself in its terms as experimental beta software, with no service-level agreements or uptime guarantees. Its privacy policy says email thread content and prompts are sent to OpenAI, which retains them for up to 30 days and does not use them for model training. Full conversation and email content is also logged to LangSmith for debugging and service improvement, with automatic deletion after 14 days. The policy lists encryption in transit, access controls, Better Auth, and regular security assessments and updates. It also recommends against using the service for highly sensitive or confidential communications.

Who it suits

Composer AI may suit Gmail users who want replies drafted from an email thread in a tone aligned with their own, then reviewed and edited before sending. It is a beta service, so it is not suited to highly sensitive or confidential communications according to its privacy policy.

Limits

The Free Beta Tier allows 20 draft compositions per account. A manual limit increase may be requested from the operator.
