Fact Check
Any Claim, Mid-Debate
Someone drops a bold number or a shaky “fact” in the middle of an argument? Check it. ArguFight pulls the claim, searches real sources, and returns an evidence-backed verdict with links. It’s informational — it never changes the score. The judge still rewards whoever debates better. What you do with the truth is up to you.
Three steps
How a Fact Check Works
Pick a claim
On any argument — your opponent's or your own — tap Fact-check. We pull out the single most checkable factual claim in it.
Gather evidence
We search real sources — Wikipedia plus live web results — and read what they actually say. No guessing from memory.
Return a verdict
You get one of four calls — Accurate, Misleading, False, or Unverified — with a plain-English reason and links to the sources.
The important part
A Fact Check Never Changes the Score
ArguFight is about who argues better — not who happens to be right. The AI judge never sees a fact check. So being “correct” isn’t an automatic win. A fact check is ammunition: if it exposes a weak claim, you still have to fold that into your next argument and out-debate your opponent to earn the points. Truth is a tool here, not a trophy.

Fact Check FAQ
Does a fact check change who wins the debate?
No. Fact check is informational only and is never read by the AI judge. ArguFight rewards who debates better, not who happens to be right. A fact check is a tool you can use — if the check exposes a weak claim, you still have to weaponize it in your next argument and out-argue your opponent.
How much does a fact check cost?
Your first fact check in each debate is free. Additional checks in the same debate cost 2 coins each, up to 3 per debate. Coins are the in-app currency you earn daily and can top up.
Who can run a fact check?
Only the two debaters in a match can trigger a fact check, but the result is public — spectators and the debaters all see the same verdict and sources.
Can a fact check be wrong?
Yes. A fact check is AI-generated from public sources (Wikipedia and web search) and can be mistaken or incomplete. It is informational only — it never affects who wins, and it is not a substitute for your own research. Every verdict links to its sources so you can check them yourself.
What does "Unverified" mean?
It means the sources we found did not clearly resolve the claim, or the statement was an opinion rather than a checkable fact. We never invent a verdict — if the evidence is not there, we say so.
Where does the evidence come from?
Every verdict is built only from retrieved sources — Wikipedia and live web search — and each check links out to what it used, so you can read the evidence yourself.
Put a Claim to the Test
Start a debate, drop a fact check when it counts, and win the argument the real way — by out-debating the person across from you.
