Jetwriter AI

Jetwriter AI is a writing assistant that runs as a browser extension, a web app and a mobile app, and works on any site rather than inside a single editor. Users select text anywhere to fix grammar, translate, summarize, explain or rewrite it, chat with the page they are reading, or draft a reply in place. It integrates directly with Gmail, Outlook, WhatsApp Web, LinkedIn, Slack, Zoho, Freshdesk and Zendesk, and can be reached from a keyboard shortcut, a right click, the extension icon or buttons added to those sites. Its distinguishing feature is personalization. The assistant analyzes past emails to learn a user's style and recurring details, then automatically drafts replies in the Gmail inbox for messages that need one while skipping newsletters and receipts. A user profile, saved writing styles, prompt templates and memory across conversations shape later responses. Models can be switched between regular and advanced tiers from OpenAI, Anthropic and Google partway through a chat, and the assistant handles file attachments in any format, voice input, live web access and a chosen response length. The extension is under 1 MB. Three plans are published. Free includes 15 regular model responses per month and no advanced model access. Elite is $18 per month, or $14 per month billed yearly, and covers roughly 1,000 advanced model responses per month, unlimited regular model responses and 50 automatic Gmail draft replies per day. Ultra is $39 per month, or $29 per month billed yearly, and raises those to roughly 2,500 advanced responses per month and 70 automatic draft replies per day. Both paid plans include the extension, web app, voice input, live web access, file attachments and priority support.
