Fact Check
Check a Claim. Get a Verdict, Backed by Sources.
Send /fact plus any claim to @vustSearchBot and get a verdict — Supported, Mixed/Contested, Unsupported, or Unverifiable — with a short rationale and the sources behind it. A sourced snapshot of what current sources say, not a truth oracle.
Limits first
A snapshot of sources, not a courtroom verdict
Some fact-check tools present a confident true/false badge regardless of how thin the evidence is. This one has a fourth option — Unverifiable — for when sources genuinely don't cover a claim yet, and a fifth-in-spirit honesty note reminding you the verdict can change as sources evolve.
See the difference
A claim you send, and the verdict band plus rationale that comes back — sources always available behind the result.
Who this fact-check mode is for
- Anyone who just read a viral claim
- A forwarded message, a headline, or a social post states something as fact and it's unclear whether it holds up.
- @vustSearchBot runs the claim against current web sources and returns a verdict band — Supported, Mixed/Contested, Unsupported, or Unverifiable — with a short rationale.
- People fact-checking before they share
- Sharing something false is embarrassing and spreads misinformation further.
- A quick /fact check surfaces whether credible sources back the claim before it gets forwarded again.
- Readers of contested or fast-moving topics
- Sources genuinely disagree, or a topic is too recent for reliable coverage yet.
- The Mixed/Contested and Unverifiable bands say so instead of forcing a false yes/no.

What's live
A sourced snapshot, not a truth oracle
The verdict reflects what current, credible web sources say right now. It is not a final ruling, and it can change as new sources appear or a story develops — treat it as a strong signal, not the last word.
The same mode and guard as a Quick search
Fact-check runs the same Quick search under the hood, with the same anti-abuse guard. There's no separate fact-check product.
Uncertainty
When sources genuinely disagree, the verdict says Mixed/Contested instead of picking a side. When there isn't enough coverage yet, it says Unverifiable instead of guessing.
Frequently asked questions
Is this a final ruling on whether something is true?
No, and it's worth being precise about this. The verdict reflects a snapshot of what current, credible web sources say — it's not an absolute truth arbitration. Sources can be incomplete, a story can still be developing, or credible outlets can genuinely disagree. Treat it as a strong, sourced signal, not a court ruling.
What do the four verdict bands mean?
Supported: credible sources confirm the claim. Mixed/Contested: sources disagree, or the claim is partially true. Unsupported: credible sources contradict the claim. Unverifiable: there isn't enough source coverage yet to judge it either way — often true for very recent or very niche claims.
Does fact-check mode cost extra?
No — it runs as a normal /search query, right inside Telegram. A failed check costs nothing. There's no separate fact-check tier.
How do I use it?
Send /fact followed by your claim (up to 500 characters), for example /fact the Great Wall is visible from space. Or send bare /fact and paste the claim as your next message. Either way you get the same verdict-band result.
Can I see the sources behind the verdict?
Yes — tap the Sources button under the result, same as any @vustSearchBot answer. Sources are always available regardless of the verdict, so you can verify the reasoning yourself instead of taking the badge at face value.
What happens if the model can't parse a clean verdict?
The result degrades to Unverifiable rather than crashing or showing a broken message — an honest "we couldn't confidently classify this" beats a confident-looking guess.
Ready when you are
