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.
Jetwriter AI
Jetwriter AI is a personal writing assistant available through a browser extension and web app. It can help compose emails and messages, correct grammar, improve or translate writing, and summarize or explain selected text. Users can create a profile, define writing styles, and use memory based on earlier conversations. The service can search the web, read live pages, and chat with files in any format; it lists GPT 6 Series, Claude Opus and Sonnet, and Gemini Pro among its models. Integrations for replying in the user's voice include Gmail, WhatsApp Web, LinkedIn, Outlook, Zoho, Slack, Freshdesk, and Zendesk. Gmail auto-drafting is optional; drafts are saved for review, editing, and sending. Its privacy notice says Gmail and Calendar data is used only for enabled drafting features, not advertising or AI training, and that email bodies and calendar events are not stored on its servers. The free plan provides 15 regular model responses monthly and no advanced responses. Elite costs $18 a month; Ultra costs $39 a month. Chrome, Edge, Brave, Opera, and Vivaldi extensions are listed, while Safari and Firefox are marked as coming soon.
