GPT for Gmail
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.
