Know what to trust on YouTube in real time

Free 30 minutes every month. No card.
Real time
Verdicts appear as you watch.
Checked against the web
Every claim is verified by live web search — up to 5 source links per verdict.
Facts, not opinions
Opinions and predictions are flagged, not judged.
Any video
From reviews and science to politics — the topic doesn't matter.
How it works
Nothing to set up
Fact-checking on YouTube in three steps — no keys, no signup.
- 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.
Features
More than “true / false”
All of it — already in the free version, no API keys or setup.
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. No keys, no setup.
Real-time checking
Facty checks the part of the video you're actually watching — your minutes are spent only on what you watch, not the whole video at once.
No side
No political stance. A two-source rule and a transparent scale — not “our opinion”.
Privacy
We work from captions. We don't store your videos, and you can try it without an account.
Chrome & Firefox
One extension for both browsers. Live streams coming soon.
Every feature is already in the free version.
Who it's for
Who pays the most for misinformation
Facty confirms what's true as readily as it debunks what's false — for any audience.
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.

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”.
We check the claim, not the person. Facty confirms what's true and debunks what's false just as readily — in any video, from any speaker, in any language.
-
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.
Comparison
Facty vs ChatGPT vs checking by hand

| Checks the whole video, not just what you noticed | Yes | Partly | No |
| Five verdict levels instead of true / false | Yes | No | No |
| Video in any language, verdict in yours | Yes | Partly | Partly |

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.
Can’t I just spot misinformation myself?
Sometimes — but the claims that stick are the ones that don’t look false: a confident tone, a specific-sounding number, a real event framed slightly wrong. You can’t pause and search the web for every one, so unchecked claims pass by default. Facty checks them in the background and shows which ones don’t hold up.
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.
Does it work on live streams?
Not yet — it's on the roadmap (coming soon). For now Facty works on recordings.
What do you store?
We don't store videos, we work from captions; you can try it without an account.
Is Facty unbiased?
Yes: we check the claim, not the person; a two-source rule; we show both truth and falsehood.
Chrome and Firefox? Mobile?
Chrome and Firefox — one extension for both. No mobile version yet.
How do I cancel my subscription?
In a couple of clicks from your account, anytime. Money for the paid period isn't lost — access stays until it ends.
