ConfuteGPT is a small Chrome extension that turns your browser into a fact-checking console for whatever article is currently open. Rather than assessing a site's reputation or a domain's history, it works on the text in front of you: GPT-3.5 Turbo reads the article, identifies statements that look false or misleading, explains why they are problematic, and hands back a reliability score from 0 to 10. An accompanying confutation section gives the counter-argument alongside the flag, so you are not just told that something is wrong.
The extension is deliberately minimal. It installs as a roughly 20 KB package, sits behind a single popup with a Start Analysis button, and keeps its configuration in a small settings page where you paste an OpenAI API key. That key requirement is the main thing to understand before installing: ConfuteGPT is a client, not a hosted service, so there is no account to create and no subscription. You pay OpenAI directly for the API calls and the extension just orchestrates them. It also means nothing works until you supply a key.
It is worth being clear about what this class of tool can and cannot do. A single-pass language model judgement is a useful second opinion on a suspicious piece of writing, and the requirement to explain its reasoning makes the output more inspectable than a bare true/false label. But reliability scores produced this way are heuristic, not authoritative fact-checking, and they can be wrong about accurate articles that merely read oddly. Use it as one input among several, alongside primary sources and established fact-checking organisations.
On maintenance: the extension was published in July 2023 and remains listed on the Chrome Web Store, still installable, with the listing dated to version 1.0. Because it targets GPT-3.5 Turbo specifically, expect the analysis quality to reflect that generation of models rather than newer ones.
