| 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. | HARPA AI is a Chrome/browser extension that layers a hybrid AI-plus-web-automation engine onto any web page, letting you access GPT, Claude, Gemini, DeepSeek, Perplexity and local Llama models with one shortcut. It's built for marketers, SEO specialists, writers, recruiters and developers who want to summarize videos and pages, draft emails, generate long-form articles, extract data and monitor sites without leaving the browser. What sets it apart is that it can actually read, navigate, click and extract from live pages and trigger Zapier/Make/n8n chains, while running locally and not logging your conversations. |
