| Description | chatgpt.js is a free, open-source client-side JavaScript library (plus an interactive CLI) that lets developers programmatically interact with the ChatGPT web interface and DOM without wrestling with the underlying markup. It's aimed at developers building browser extensions, userscripts, and web integrations, and it's known for being lightweight, object-oriented, and ultra-flexible — the same function can be called multiple ways (e.g. chatgpt.getLastResponse() or chatgpt.response.getLast()). What sets it apart from raw API wrappers is that it drives the existing ChatGPT UI directly, powering practical helpers like auto-continuing cut-off responses, keeping sessions fresh past time limits, and sentiment analysis. | Vercel is the platform for frontend developers, providing the speed and reliability innovators need to create at the moment of inspiration. Built by the creators of Next.js, Vercel powers Nike, eBay, Mercedes-Benz, and millions of developers. |
