Frequently Asked Questions
What is JetWriter AI and what does it do?
JetWriter AI (formerly ChatGPT Writer) is a Chrome browser extension and web app that provides AI writing assistance across Gmail, LinkedIn, Outlook, and any webpage. Launched in December 2022 and rebranded in September 2025, it is used by over 600,000 users. Core features include context-aware email reply generation, grammar correction, tone adjustment, text summarization, translation, and support for multiple AI models including GPT-5, Claude, and Gemini.
How much does JetWriter AI cost?
JetWriter AI has three pricing tiers. The free plan includes 15 AI responses per month. Pro costs $12/month ($9/month billed annually) and includes unlimited responses and priority support. Elite costs $18/month ($14/month billed annually) and provides access to the best-quality AI models for complex reasoning tasks. Users can also supply their own OpenAI, Anthropic, or Google API key as an alternative to plan-based credits.
What are the main features of JetWriter AI?
JetWriter AI's main features are context-aware email reply drafting in Gmail and LinkedIn (reading the full thread automatically), multi-model AI access (GPT-5, Claude, Gemini), personalized writing style profiles, one-click grammar fix and tone change, text summarization, multilingual translation, and voice-to-prompt input. It works on any text field on any website, not just email platforms.
Is JetWriter AI free to use?
Yes, JetWriter AI has a free plan with 15 AI responses per month — enough to test the product but insufficient for daily professional use. Most power users hit the limit within 2-3 days. The Pro plan at $12/month removes the response cap. Users can also bypass plan limits entirely by connecting their own AI provider API key.
What are the best alternatives to JetWriter AI?
The closest alternatives to JetWriter AI are Monica.im and MaxAI.me, both of which offer browser sidebar AI writing assistance with similar multi-model access. Grammarly is a stronger choice for users whose primary need is grammar and style correction rather than content generation. For email-specific AI, HubSpot's AI email writer or Gmail's built-in Gemini integration are platform-native alternatives.
Who is JetWriter AI best for?
JetWriter AI is best suited for sales professionals, account managers, and customer support agents who write large volumes of emails and LinkedIn messages daily. Its context-aware threading makes it significantly faster than copy-pasting into ChatGPT for email replies. It is not the best fit for long-form content creators (blog posts, reports) or users on Safari or Firefox, where full extension functionality is not yet available.
Does JetWriter AI have an API?
JetWriter AI does not offer a public API for developers to build on. However, it does support bringing your own API key (OpenAI, Anthropic, Google), allowing users to route requests through their own AI provider accounts for cost control and model flexibility. This is documented on the JetWriter blog and available in account settings.
