What is Jetwriter AI?
Jetwriter AI is a personal AI writing assistant available as a lightweight browser extension (under 1 MB) for Chrome, Edge, Brave, Opera and Vivaldi, plus a web app for mobile and unsupported browsers. It routes requests to several frontier models, including GPT-series, Claude and Gemini models, and lets you switch models during a chat.
In practice you can select any text on a page and fix grammar, translate, summarize, explain or improve the writing, or use the chat to ask questions about the open page or uploaded files. The Gmail integration learns from your past emails to draft replies in your voice, and it can draft replies automatically when a message needs one. It also supports voice input, saved prompt templates, custom writing styles and live web search.
