Truth by LetBe.ai
An AI fact checker that works while you watch
An AI fact checker takes a claim, looks for evidence and returns a verdict with its reasons. Truth by LetBe.ai is a Chrome extension that does this on videos, meetings and pages as they play, marking each claim TRUE, FALSE, PARTIAL, UNCLEAR or OPINION right on the page.
Free to try. No card needed.
What can it check?
Anything with spoken claims in a browser tab: a video, a live stream, a recorded meeting, a lecture. Truth starts only when you press Start for the current tab. It listens to the tab's audio by default, or reads the captions when you choose captions mode, picks out the claims worth checking, and shows a verdict for each one as a small note on the page while the video keeps playing. A Truth Meter keeps a running picture of how the claims are holding up, and you can step back through recent results.

What do the five verdicts mean?
TRUE
The evidence supports the claim as stated.
FALSE
The evidence disproves it. A claim is never marked FALSE only because nothing confirmed it. FALSE needs disproof.
PARTIAL
Part of the claim holds and part does not, or it needs a qualification the speaker left out.
UNCLEAR
The evidence is missing or conflicting, so no honest verdict is possible yet.
OPINION
A judgement or preference, not something that can be checked.
The verdicts page explains how each one is reached.

A wallet you top up when you choose
Later, checking spends credits from a LetBe.ai wallet that you top up when you choose.
Never collects keystrokes
Truth never collects keystrokes, passwords or your browsing history.
How is this different from pasting a claim into a chatbot?
A chatbot answers the question you typed, once, in a separate window. Truth stays with what you are watching. It hears the claims as they are made, checks them as they come, and puts the verdict where the claim is, so you do not have to stop, transcribe and ask. It also carries a discipline a chat window does not: the burden of proof stays on the claim, and unconfirmed is not the same as false.
AI fact checker questions
What can it check?
Videos, live streams, meetings and lectures playing in a Chrome tab. Truth listens to the audio, or reads the captions in captions mode, and checks the claims it hears while the tab keeps playing.
What do the five verdicts mean?
TRUE, FALSE, PARTIAL, UNCLEAR and OPINION. FALSE is given only when the evidence disproves the claim, never just because nothing confirmed it. The verdicts page has the full rules.
Is it free to try?
Yes. Truth installs with free guest credits, so the first checks cost nothing. After that a prepaid LetBe.ai wallet pays for what you check, and you top it up only when you choose.
Can an AI fact checker be wrong?
Yes. Truth is an AI-assisted research aid, not a guarantee of truth. Every verdict comes with its reasons so you can judge the evidence yourself, and UNCLEAR is a real answer when the evidence is not there.
