PageSage attacks a very specific annoyance: pages full of questions that you have to answer or look up one by one. Study guides, quiz pages, FAQ sections and training material all pile up questions, and switching between the page and a search engine is slow. The extension scans the active tab, detects the questions it finds there, and returns AI-generated answers inside a compact popup, so you never lose your place.
There are two modes. If you only care about one question, you highlight it, right-click and choose the answer action to get a single response. If you are facing a page full of them, you click the toolbar icon and the extension works through all detected questions at once. It is a deliberately narrow tool: it is not a general chat sidebar and does not try to do everything a browser assistant can do.
PageSage is published by an independent developer ([email protected]) under an MIT licence and is not affiliated with OpenAI. Notably, the extension does not ship with an API key — the listing states this explicitly, which means you supply your own OpenAI credentials for it to function. The listing also warns that since answers come from GPT models, they can contain inaccuracies, and that support for complex websites is still expanding. The last published update, version 1.03, dates from January 2024.
