About Jetwriter AI
Jetwriter AI is a browser extension and web app powered by models such as GPT-5, Gemini and Claude that helps you write emails and messages on sites like Gmail, Outlook and Slack, chat with the page, fix grammar, improve your writing, translate and create summaries. It also analyzes your past emails to learn your writing style, so generated replies sound more like you wrote them yourself; in Gmail, when an email needs a reply, it automatically drafts one, and emails that don't need a reply are skipped. It also offers voice input, real-time web access, file attachments and priority support.
