Jetwriter AI

Jetwriter AI is a powerful browser extension and mobile app that integrates seamlessly into Gmail, WhatsApp Web, LinkedIn, Outlook, Slack, and other popular platforms. Instead of switching between tabs, you can write, reply, and edit text directly where you work. The tool is powered by advanced AI models—GPT-5, Claude Sonnet, and Gemini Pro—and lets you switch between them mid-conversation to find the best response for your needs. Personalization is at the heart of Jetwriter AI. You can create a personal profile so responses match your unique voice and tone, set up custom writing styles for different situations (professional, casual, creative), and save frequently used prompts as reusable templates. The extension learns from your past emails to help you reply in your own voice, making responses feel authentic rather than generic. Beyond composition, the tool handles text refinement instantly. Select any text on a webpage to fix grammar, translate, summarize, explain, or improve it—all without leaving the page. Live web access means you get real-time information, while document chat lets you upload files and ask questions about their content. Voice input works in any language, and you control response length with a simple slider. The lightweight extension (under 1MB) runs efficiently with privacy built in. Your data is encrypted in transit, never shared with third parties, and never used to train AI models. Keyboard shortcuts make common tasks instant, while the interface remains clean and accessible for writers of all skill levels.
