Composer AI vs GPT for Gmail

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.

GPT for Gmail drafts replies, writes new messages, and summarizes email threads inside Gmail. It reads the full thread to create a contextual reply that can be inserted with one click. Listed tools include email search, response generation, cold emails, templates, subject lines, inbox organization, scheduling, and follow-ups. Users can choose a tone, and the product says translation is supported in more than 30 languages. It is available through the Google Workspace Marketplace, with a Chrome extension for GPT Workspace and integrations with Docs, Sheets, Slides, and Drive. Gmail reply suggestions and drafts work on iOS and Android. The maker says emails are anonymized before processing, not shared or commercially used, and not used to train AI models. The Free plan is free with no feature restrictions. Unlimited Premium costs $9 a month, billed annually, adding higher usage limits and priority support. There is no free trial.
