Jetwriter AI

Jetwriter AI is a browser extension and application that provides personalized AI writing assistance across multiple digital environments, including Chrome, desktop, and mobile platforms. The tool integrates directly into popular web services such as Gmail, Outlook, LinkedIn, WhatsApp Web, Slack, Zoho, Freshdesk, and Zendesk, allowing users to interact with AI without switching tabs. When composing emails or messages, Jetwriter AI can generate replies in the user’s own voice by learning from past email correspondence, ensuring consistency in tone and style. The extension supports real-time text transformation: users can select any piece of text on a webpage—whether in an email composer, a social media post, or a document—and apply actions such as fixing grammar, translating into other languages, summarizing lengthy content, explaining complex concepts, or improving overall writing clarity. The underlying AI models include GPT-5.1, Claude, and Gemini, offering varied capabilities for different tasks. For example, GPT-5.1 is used for fast and natural language generation, Claude provides nuanced reasoning and longer context handling, and Gemini excels at multimodal understanding. Jetwriter AI also includes a “chat with page” feature that lets users ask questions about the current webpage content, enabling quick research without leaving the page. The tool is free to try, with no upfront payment required, and has been adopted by over 700,000 users who find email composition and web-based writing tasks time-consuming. Specific use cases include drafting customer support tickets in Zendesk, translating Slack messages from colleagues in different languages, summarizing long articles on LinkedIn, and polishing informal WhatsApp chats into professional language.
