Precision argument analyzer

Check the facts.
Break the logic.
Get the comeback.

Anyone can tell you a post is false. BSChecker shows you where the argument falls apart even when the facts are right — and writes the rebuttal for you.

3-day free trial — up to 25 analyses. No commitment.

A claim can be 100% true and still be a garbage argument.

Other tools mash "is it true?" and "does it make sense?" into one verdict. We don't. BSChecker splits them — so you can flag a true premise that's been twisted into a broken argument, and walk away with the line that ends the thread.

Holds

Facts check out and reasoning survives stress tests.

Self-defeating

True facts, broken logic — turn the argument against itself.

Fails

False premise, leaky logic, or both — here's why.

One box. One verdict. One kill shot.

01

Paste

Drop in a claim, post, or argument. Or highlight one online with the extension.

02

Snap

Verdict, confidence, and a 0–100 strength meter — one glance tells you the call.

03

Comeback

Ranked attacks. Top one is the kill shot. One tap copies it.

Simple pricing. Win more arguments.

Every plan starts with a 3-day free trial (up to 25 analyses).
