Jetwriter AI vs MailSome

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.
