Everything you need to know about our free YouTube video fact checker
It's a free AI-powered tool that analyzes YouTube videos for factual accuracy. It extracts claims from the video transcript, verifies them, and provides a credibility score with detailed explanations. It's made by LunaNotes, and it runs one step of that app on its own.
LunaNotes is an AI note-taking app. You bring a source — a video, a PDF, an audio file, a meeting, or your own writing — and it produces a structured note you can edit, plus diagrams, flashcards and an AI chat built from that note. YouTube is one of the places a source can come from, not the whole product. This tool exists so you can judge the output before you sign up for anything.
The free plan gives you 100 AI credits a month (roughly 10 notes or 20 diagrams), 100 MB of storage for files you upload, 5 AI diagrams and 5 flashcard decks — no credit card. That's where a fact check stops being a fixed public page and becomes a working document: annotate each claim, keep your own sources beside it, and chat with the material.
Our AI analyzes the video's transcript to identify factual claims, statistical statements, and assertions. It then evaluates each claim and assigns a verification status (verified, misleading, false, or unverifiable) along with an overall credibility score.
Use it as often as you like — this tool is free and we don't meter it. What an account adds isn't more runs, it's somewhere for the results to live: private notes you can edit, organise and come back to.
Our AI provides a thorough analysis, but it should be used as a starting point for your own research. AI-generated sources and verifications may not always be 100% accurate. We recommend cross-referencing important claims with authoritative sources.
Not on this page — what the free tool produces is a fixed, public, shareable report. Editing is exactly what LunaNotes is for: run the same video in a free LunaNotes account and the analysis arrives as a note you can rewrite, correct, and hang your own sources and reasoning off.
No. The tool works without an account and there's no credit card anywhere in the flow. An account is what you want when you'd like to keep the result, edit it, and build on it.
The credibility score ranges from 0-100. Scores above 70 indicate generally credible content, 40-70 indicates mixed credibility, and below 40 suggests low credibility with multiple questionable claims.
Yes! After generation, you'll receive a unique URL that you can easily share with others. The results page includes the full analysis, claims breakdown, and credibility score.
Yes. Pick a language in the form and the analysis is written in it — we support 12+, including Spanish, French, German, Portuguese, Japanese and Chinese. Leave it on "Auto" and we follow the video's own language.
