ChatGPThing

ChatGPThing occupies a simple but useful niche: instead of switching to a separate ChatGPT tab and manually pasting text, it lets you open a prompt panel on any page and ask questions about that page's content. The extension is designed around the idea that most useful AI questions are contextual — you are reading a GitHub issue, a pricing table or a support thread, and you want an answer that already knows what you are looking at.

The developer describes the typical workflow as finding information faster, generating replies to direct messages, comparing SaaS pricing plans, enhancing Stack Overflow answers and summarising GitHub issues. A keyboard shortcut toggles the tool on any page, and the whole thing is published as open-source code in the kant01ne browser-extensions repository on GitHub, so the implementation can be inspected and forked.

It is a small, single-purpose utility rather than a full AI workbench. The listing shows a modest user base and the last update was early 2023, so it is best treated as a dependable little companion for contextual questions rather than something that ships new model integrations frequently. The extension declares that it does not collect or sell user data.
