How to fact-check a YouTube video
Three steps from install to your first verdict.
- 1
Play a video
Facty picks up YouTube captions on its own. No keys, no settings — just watch.
- 2
AI checks as it goes
It pulls out checkable claims, searches the web and cross-checks independent sources — piece by piece, while you watch.
- 3
See the verdict
A card pops up over the player at the right moment; the full breakdown lives in the side report panel.
Ready to go the moment you install.
How we check
Why you can trust the verdicts
For a fact-checker the big question is “why should we trust you?”. We answer with method, not promises.
Facty doesn’t just “ask an AI if it’s true”. For every claim in the video it runs a web search and compares what it finds. Only then does it give a verdict on the five-level scale. And when there are no reliable sources, it says so honestly: “unverifiable”.
-
Two-source rule
Facty gives a verdict only when independent sources back the claim. If there are no reliable sources, it says “? Unverifiable” instead of guessing.
-
Sources always up front
Every card links to the primary sources — you can double-check everything yourself.
-
AI can be wrong — we don't hide it
Every card has a “report a wrong verdict” button. You help — we fix.
-
On no one’s side
Not even yours. The AI checks the claim, not the speaker, staying unbiased, and shows both truth and falsehood.
-
Privacy
We work from captions and don't store your videos.
See for yourself — sources are always up front.
More than “true / false”
What the AI fact-checker does
All of it works in the free version.
Tells facts from opinions
Facty doesn't argue with opinions or jokes: it flags 💬 Opinion and 🔮 Prediction, and checks only what's actually checkable.
Full video report
The side panel gathers every claim, verdict and source into one breakdown — easy to go back and re-check.
Any language, out of the box
Video in English, German, Spanish? Verdicts and sources come in your language.
Report panel
The whole video, broken down in one place
While cards pop up over the player, the side panel builds the full report: every checked claim with its timecode, verdict, explanation and source links.
- Every checked claim in order, in one list
- Click a claim to jump to the moment it was said
- Sources under each verdict — open them and see
Who it's for
Who pays the most for misinformation
Facty pays off most where a mistake costs money, reputation or a grade.
News & politics viewers
In news and political clips there's plenty of spin — you can't check it by ear, the correction surfaces late, and by then the claim is already something you've repeated.
You decide what to believe right away: Facty shows where the truth is while you watch.
Traders & investors
A single unchecked headline can cost more than a yearly subscription.
Central-bank statements, earnings, crypto influencers — with sources in seconds. Decisions on facts, not hype.
Journalists & researchers
Re-watching an hour of video for three quotes is expensive.
Facty hands you a full report: every claim, verdict and cited source — ready material, not a paraphrase.
Students & the curious
It's easy to take a confident tone for truth and memorize a mistake.
Understand the topic instead of taking it on faith: every point has sources one click away.

FAQ
Frequently asked questions
How do I fact-check a YouTube video?
Install Facty and play a video. The extension reads the captions on its own, pulls out checkable claims, and verifies them against independent web sources. Verdicts appear on a 5-level scale right over the player, as you watch.
How is Facty different from ChatGPT or plain search?
It works on its own and on time: no copying quotes or typing queries — verdicts appear over the video the moment a claim is made. Each comes with source links, not an answer “from memory”. And Facty checks the whole video, not just what you happened to notice.
Which languages are supported?
Video in any language; interface and verdicts in EN / RU / ES (more to come).
Do I need captions? What if there are none?
Yes, Facty works from YouTube captions (auto-generated ones work too). With no captions at all there is nothing to check.
How accurate are the verdicts? Can Facty be wrong?
It can, like any AI. That’s why a verdict is issued only from independent sources (the two-source rule), links are always open for you to verify, and every card has a “report an error” button.
Does Facty slow down my browser or the video?
No: all the checking runs on our server, the extension only shows results. The video plays as usual.
What counts as a “minute” of quota?
Minutes of the video you are checking. Each checked minute covers real work: extracting the claims in it, then searching the web and reading sources for every one. Watch without checking and no quota is spent.
How do I cancel my subscription?
In the extension: Facty icon → “Manage subscription”. Cancel anytime; money for the paid period isn’t lost — access stays until it ends.
