Every Claim in Any Video, Verified
Videos can contain dozens of factual assertions in minutes. Truthify identifies every one of them and checks each against real evidence — so you know exactly what to trust.
The Problem with Unverified Video Claims
Video content is persuasive in ways that text simply isn't. A confident presenter, compelling visuals, and emotional music make claims feel true regardless of whether they are. Research from MIT's Media Lab found that false information spreads significantly faster on social platforms than true information — and video is the most shared format. When a health influencer claims a supplement cures inflammation, when a political commentator states a statistic about crime rates, when a documentary presents a historical claim as settled fact — how many viewers stop to verify? Almost none. Truthify makes that verification automatic.
What "Verifying a Claim" Actually Means
Verifying a claim is not the same as Googling it. Google gives you pages that mention the topic — which may include both accurate and inaccurate information. Proper claim verification means:
Truthify's pipeline handles all four steps automatically, querying multiple authoritative sources and presenting the results transparently.
How Claims Are Extracted from Video
Not every sentence in a video is a claim. Truthify distinguishes between factual assertions (things that can be checked against evidence), opinions (value judgments that can't be verified), and unclear statements (vague or context-dependent). Only factual claims move through the full evidence retrieval and verdict pipeline. This keeps results focused on what's actually checkable and prevents the tool from wasting time on statements like "this is amazing" or "I believe we should do better."
Claim Types Truthify Identifies
Statistical Claims
Numbers, percentages, rates, and quantities attributed to research or data sources.
Historical Claims
Events, dates, and attributions from history — who did what, when, and where.
Scientific Claims
Statements about how the world works: cause-and-effect, biological facts, physical laws.
Comparative Claims
"X is larger than Y", "Z is the most/least/first/only" — any superlative or comparison.
Geographic & Demographic
Population figures, area statistics, economic indicators, country-level data.
Attribution Claims
Quotes and positions attributed to named individuals, organisations, or governments.
Share Verified Reports
Once Truthify finishes analysing a video, you can save the results as a private report or publish it as a shareable URL. Published reports are accessible to anyone and include all verdicts, reasoning, and sources — making them useful for fact-checking threads on social media, journalism workflows, classroom exercises, or simply sending to a friend who watched the same video and came away with a different impression of the facts.
Frequently Asked Questions
How do I verify claims in a YouTube video?
Paste the YouTube URL into Truthify. The tool automatically transcribes the video (using existing captions), identifies every factual claim, searches for evidence across academic and authoritative sources, and assigns a verdict to each claim — with the sources cited so you can verify independently.
Can I verify claims in a video without transcribing it manually?
Yes. Truthify handles transcription automatically using the video's existing caption track. You don't need to type anything from the video — just paste the URL.
What evidence sources does Truthify search?
Truthify searches up to ten sources depending on the claim type: Google Fact Check API for existing professional fact-checks, Wolfram Alpha for computational and scientific verification, Wikipedia, PubMed for medical research, arXiv for physics and astronomy, OpenAlex for academic papers, ConceptNet for common knowledge, and Gemini (live web search) for current events and general claims.
Can I share the results of a video fact check?
Yes. After analysis, you can save the results as a report and publish it as a public URL. The shared report includes all claims, verdicts, reasoning, and sources.
What if a claim is too new for evidence to exist?
Truthify returns an 'Unverifiable' verdict if no relevant evidence is found. This can happen with very recent events, highly specific claims, or topics with limited published research. Unverifiable doesn't mean false — it means the evidence wasn't available.
