About ClaimCraft Play

How it works

ClaimCraft teaches you to argue the way careful thinkers do: a claim needs real evidence, and reasoning that links the evidence to the claim. Then you handle the other side.

• Argument Studio — tap the pieces (evidence, reasoning, a qualifier, a rebuttal) onto a claim and watch a live strength meter climb from Rickety to Ironclad. Weak or sneaky pieces pull it down. A hint unlocks after you check it.
• Fallacy Hunt — read what someone says and spot the sneaky thinking move. There are 12 to learn, and every choice comes with a reason.
• Concept kits — 16 short question rounds, from claims-and-evidence basics to advanced synthesis.

Our privacy promise

ClaimCraft Play is free, works offline, and collects nothing. No accounts, no ads, no tracking, and no data ever leaves your device — your progress, level, and streak are saved only in this browser.

Mistakes are part of it

You never lose anything for a wrong try. A weak argument gets a gentle note about what would make it stronger, and hints teach you how to think it through — not just the answer. That's how real reasoning is learned.
