A browser extension and web app that brings AI writing, email drafting, translation, and page chat to any website, powered by GPT, Claude, and Gemini models.
About
Jetwriter AI, formerly known as ChatGPT Writer, is an AI writing assistant delivered as a browser extension and a web app. It solves a common productivity problem: instead of copying text into a separate chat window, users can write emails, fix grammar, translate, summarize, and ask questions about any webpage directly on the site they are already viewing.
The product works across any website, with deeper integrations for Gmail, Outlook, LinkedIn, WhatsApp Web, Slack, Zoho Mail, Freshdesk, and Zendesk. It draws on multiple AI models, including the GPT-6 series, Claude Opus and Sonnet, Gemini Pro, and DeepSeek, and lets users switch models mid-conversation. Responses can be personalized through a user profile, saved writing styles, and memory of past conversations. The extension is under 1MB, and a web app covers mobile devices and browsers without extension support.

Who It's For
Jetwriter AI is aimed at professionals who write many emails and messages each day, including sales, recruiting, and consulting roles. Customer support teams can use the Freshdesk and Zendesk integrations to draft consistent ticket replies faster. Content creators and marketers can generate and refine copy without leaving their workflow, while students and researchers can summarize papers, get explanations of complex topics, and chat with documents. Freelancers who juggle client communication across Gmail, LinkedIn, and Slack are another natural fit.
