What is MDN Plus?
AI Help is an AI-powered assistant available through MDN Plus that provides real-time assistance for web development questions. It utilizes OpenAI's GPT-4o mini for free MDN Plus users and GPT-4o for paying subscribers to search and summarize MDN's comprehensive documentation database. The tool specializes in answering web development queries about HTML, CSS, JavaScript, and APIs by locating relevant MDN articles and presenting concise summaries with direct source links.
Key features include asking web development questions directly through a chat interface, content search that locates relevant MDN articles, summary generation with options to explore sources directly, and code testing through the MDN Playground to verify code examples immediately. AI Help also draws on external knowledge for web development topics not covered in MDN, always clearly indicating when sources come from outside MDN.
AI Help is designed for web developers, programmers learning web technologies, and anyone needing quick access to MDN's documentation. It requires a Mozilla Account and MDN Plus account (free or paid) to access. The tool is currently in beta and available to logged-in users who want to optimize their search processes and find coding information quickly.
The feature includes chat history management, the ability to edit questions for new answers, a thumbs-up/down rating system for feedback, and direct issue filing for incorrect answers where engineers will review and respond quickly.

What if AI Help gives incorrect answers?
You can rate answers using the thumbs-up/down mechanism. If an answer is incorrect or unhelpful, file an issue using the provided template, and one of Mozilla's engineers will review it and get back to you quickly.
Does AI Help only work with MDN content?
AI Help specializes in searching and summarizing MDN content, but for web development queries not covered in MDN, it draws on external knowledge. It always clearly indicates when sources are from outside MDN.
Can I save my AI Help conversations?
