Description

GPT Detector ("GPT Detector for StackOverflow") is a free developer browser extension that queries ChatGPT and compares answer similarity to help identify fake or AI-generated answers on Stack Overflow. It's aimed at developers who want to gauge the authenticity of the answers they rely on. Note that the extension is no longer listed in the Chrome Web Store and reportedly runs only in non-Chrome browsers such as Brave.

CastReader is a text-to-speech reader available as browser extensions and mobile and desktop apps. It reads webpages, PDFs, Kindle books and AI chatbot answers aloud with synced highlighting.
