The flow behind Truth by LetBe.ai: claims out of a video, verdicts back
Truth by LetBe.ai is a Chrome extension that checks claims while the user watches, listens or reads. It runs as a LetBe.ai flow: audio or page text in, transcription, claim extraction, verification and a verdict for each claim. This page shows that chain.
Free to start. No card needed.
The block chain
The extension sends a short window of audio, captions or page text only while the user has pressed Start on that tab.
Audio window, captions or page text from the tab the user started, nothing else.
Turns the audio window into text. Skipped when captions or page text arrive.
Picks out the concrete, checkable statements and drops opinion and filler.
Looks each claim up against sources the flow can reach.
Returns true, false, unclear, opinion or partially true, with the reasoning and links.
Refuses to call something false without a source that disproves it.
Structure only. The instructions inside the Prompt blocks and the documents behind the search are the product's own and stay private; you write yours.
Try it, build it, keep what is yours
Build the same shape
Paste the description below into the portal's scenario builder. It drafts these blocks with empty prompts.
Fill the gaps yourself
Your instructions, your documents, your rules. The product's own prompt text is never published.
Build this shape in the portal
Open the portal, choose Describe, and paste this. The scenario builder drafts the blocks above with empty prompts, and you fill in your instructions, documents and rules.
Then test it in the chat console next to the canvas, and publish it as a live address or a shareable chat page. Free to start, no card, nothing to host. The AI flow builder page explains each block type.
Truth flow questions
What are the five verdicts?
True, false, unclear, opinion and partially true. Every verdict comes with the reasoning and a link, and Truth is an aid to research, not a guarantee.
What does the extension send?
Only the audio window, captions or page text needed for the check, from the active tab, and only after the user pressed Start.
Can I run the checker on a document instead?
Not with the extension; build the flow from the description above and send it any text you like from your own code or the chat console.
Why the rule about false verdicts?
Burden of proof. A claim that cannot be disproved with a source is unclear, not false. The Guardrail block enforces that on every claim.
