ChatGPT Writer (now Jetwriter AI) is a lightweight browser extension that helps you write emails, reply to messages, fix grammar, translate text, and summarize content on any website. It integrates directly into Gmail, LinkedIn, Outlook, and other platforms with context-aware AI that reads conversation threads to generate relevant replies.

• Context-Aware Email Replies: Reads your email thread and generates relevant, personalized replies without copy-pasting. Works directly from the Gmail reply toolbar.
• Works on All Websites: Use AI writing assistance on any site including LinkedIn, WhatsApp, Outlook, Zendesk, and more through a browser extension, keyboard shortcut, or text selection.
• Multi-Model AI: Powered by top AI models including GPT-5, Claude, and Gemini, giving you access to the best available intelligence for different tasks.
• Grammar & Text Transformation: Select any text to fix grammar, improve clarity, rephrase content, change tone, or translate into any language instantly.
• Chat With Any Page: Summarize articles, find key information, proofread content, and get explanations for complex terms on any webpage.
• Voice Input: Dictate prompts using accurate voice-to-text in any language for hands-free writing.
• Custom Prompts & Saved Styles: Save and reuse common writing prompts for one-click access, and store your preferred writing styles for consistent output.
• Lightweight & Non-Intrusive: Under 1MB extension that opens as a draggable modal on top of your page rather than a bulky sidebar.

• Fast Email Drafting: Generates complete, well-worded email replies in seconds, saving significant time on routine correspondence.
• Privacy-Focused Design: Data is not used for AI training, and communication is handled with standard encryption practices to protect user information.
• Works Everywhere: Compatible with all Chromium browsers (Chrome, Edge, Brave) and works on any website, not just email clients.
• Multilingual Support: Write and translate in dozens of languages, making it useful for international communication.
• Easy to Use: Simple interface with multiple launch options including keyboard shortcuts, text highlighting, right-click menu, and toolbar buttons.
• Free Tier Available: Get started without paying, allowing you to test the tool before committing to a subscription.

• Limited Free Plan: Only 15 AI responses per month on the free tier, which most active users will exhaust quickly.
• Chromium-Only: No support for Safari or Firefox yet, limiting access for users on those browsers.
• Best for Short-Form Content: Primarily designed for emails and messages. Less suited for long-form documents or complex writing projects.
• Customization Takes Time: Getting the AI to match your personal writing voice requires initial setup of prompts and style preferences.
• Output May Need Review: Like most AI writing tools, responses can sometimes be inaccurate, outdated, or not fully aligned with the intended tone, so manual checking is still needed.

• Managing a Busy Inbox: You receive dozens of emails daily that need thoughtful replies. Highlight the email thread, trigger ChatGPT Writer, and get a context-aware draft reply in seconds. Edit lightly and send, cutting email time by half.
• Cold Outreach for Sales or Freelancing: Writing personalized cold emails to prospects is time-consuming. Use the tool to draft outreach messages based on brief prompts about your offer and the recipient's pain points, then customize each one.
• Customer Support Responses: Support agents handling tickets on Zendesk, Freshdesk, or email can generate professional, empathetic replies that address the customer's specific issue. The context-aware feature reads the full conversation thread.
• Non-Native Language Communication: You need to write professional emails in a language that isn't your strongest. Use the translation and tone-adjustment features to compose messages that read naturally in any language.
• LinkedIn Networking: Craft personalized connection requests and follow-up messages directly on LinkedIn without switching tabs. The extension works right within the platform's messaging interface.
• Quick Content Summarization: You've received a long email chain or need to review a lengthy article. Use the "Chat with Page" feature to get a quick summary of the key points before responding.
