How to fact-check a YouTube video (free, in under a minute)

To fact-check a YouTube video: pin down the exact claim it's making, find two or more independent sources that confirm or contradict it, and ask what context the video left out. If you want the answer instantly, paste the link into an AI checker that scores the whole video for you. Here's both ways.

The 60-second manual method

Find the specific claim. Separate the fact from the feeling. "This food is dangerous" is a vibe; "this additive causes X according to a 2019 study" is a claim you can check.
Search for independent confirmation. Look for two or more credible, unrelated sources — not the same press release reworded. If only the video (or sites selling the same thing) make the claim, that's a flag.
Check what's missing. Dates, location, sample size, and the question behind a quote all change meaning. Misleading videos are often technically true but missing the context that matters.
Check the incentive. Notice where the video wants you to go next — a course, a coin, a supplement. A sales funnel dressed as advice deserves extra scrutiny.

The instant method: an AI trust score

Doing that by hand for every video is slow. Veralyze does it automatically: paste any public YouTube link and in about 18 seconds it reads the transcript, extracts every factual claim, checks each against independent sources (supported, contradicted, mixed, or unverified), flags manipulation tactics with a direct quote, and gives the video a trust score from 0 to 100. It's free to start, no sign-up needed, and it works on videos in any language.

Which claims should you check first?

Start with the claim the video is built around — the one that, if false, changes everything. Money ("guaranteed returns"), health ("this cures X"), and news ("this happened here, now") are the three areas where a wrong claim does the most damage, so check those hardest.
