What is Jetwriter AI (formerly ChatGPT Writer)?
Jetwriter AI is a browser extension and web app writing assistant that helps you draft emails, fix grammar, rephrase text, translate, and chat with any webpage without leaving the site you are on. It runs inside Gmail, Slack, LinkedIn, WhatsApp Web, Outlook, Zoho, Freshdesk, and Zendesk, and you can also launch it on any page with a keyboard shortcut or by selecting text.
Where most writing assistants keep you in a separate tab or a single editor, Jetwriter AI is built to stay in your workflow. It lets you switch between GPT-5, Claude, and Gemini models mid-conversation, drafts Gmail replies from your past email history, and adds one-click actions for grammar fixes, summaries, and translations on highlighted text. The trade-off is that advanced models and higher Gmail auto-draft limits sit behind paid tiers.
It fits remote workers, sales reps, and support teams who write dozens of messages a day and want replies that sound like them rather than generic AI output. Non-native English speakers also get grammar correction and tone adjustments without copying text into another tool.
