Scan AI-generated contChatGPT, Claude, and Gemini all sound conﬁdent even when they're wrong.This tool scans any AI-generated text, ﬂags the speciﬁc claims most likely to be hallucinated (stats, dates, quotes, names, "studies show" lines), ranks how risky each one is, and hands you a fact-check plan. Runs entirely in your browser: nothing you paste is uploaded or sent to a server. No account, no API key, free with no usage limit.

Hey Product Hunt I’m John, the creator of AIToolCritic, and I built **AI Hallucination & Fact-Checker** for anyone using ChatGPT, Gemini, Claude, or other AI tools to create content, research, posts, emails, scripts, or articles. The goal is simple: help you catch claims that might be wrong, unsupported, outdated, or too confident before you publish or send them. Here’s the exact way I use it: 1. Paste in an AI-generated answer. 2. Let the tool scan for risky claims. 3. Review anything that needs a source, rewrite, or second look. 4. Clean up the output before it causes problems. One mistake I see all the time is trusting AI because the answer “sounds right.” If your output looks weird, it’s usually because the AI filled in gaps too confidently. This tool is browser-based, free to use, and designed for beginners, creators, bloggers, students, and anyone who wants a quick reality check before using AI content. I’d love feedback from the PH community — especially on what types of hallucinations you’d want it to catch better next.

love that it runs in the browser, makes me way more comfortable pasting sensitive drafts in. one thing i'd really want is a way to export the fact-check report as a pdf or markdown so i can attach it to client deliverables instead of just glancing at it on screen.

finally something that tells me which "studies show" lines are made up without me copy pasting into five tabs. loved that nothing leaves my browser, would actually use this at work.
