Jetwriter AI

Jetwriter AI is a personal AI writing assistant that operates as a lightweight browser extension (less than 1MB) and a web app. It helps users write emails and messages, chat with page content, fix grammar, improve writing, translate, and perform other text transformations on any website. The tool integrates deeply with popular sites like Gmail, LinkedIn, Outlook, Slack, and Zendesk, allowing users to reply to emails and messages in their own voice. It learns from past emails for personalized responses. Features include customizable writing styles, the ability to switch between AI models (GPT-5, Gemini, Claude), live web access, chat with documents, voice input, response length control, and prompt templates. Users can access the tool via text selection, right-click context menu, keyboard shortcut (Ctrl+Shift+K), extension icon, or integrated buttons on supported sites. The extension is available for Chrome, Edge, Brave, Opera, and Vivaldi, with Safari and Firefox coming soon. The tool supports all languages and emphasizes privacy, stating data is not shared with third parties, not used for AI training, and encrypted in transit.
