ClaimCraft

Learn to argue the way careful thinkers do — a claim, real evidence, and reasoning that links them. Meet the guides who each teach one piece of a strong argument, then build one yourself.

Build & test arguments

Two hands-on reasoning surfaces — the same skills as the iOS app, rebuilt for the browser.

Argument Studio Tap evidence, reasoning, and rebuttals onto a claim and watch your argument's strength meter climb. Fallacy Hunt Read what someone says and spot the sneaky thinking move — 12 fallacies to catch. Reasoning Lab Steelman an opposing view before you rebut it, and read laterally to judge whether a source can be trusted. Two moves that make you hard to fool.

Play together

Two ways to keep going — a same-device match with friends, or a trail through every kit. On-device only; nothing leaves this device.

Reasoning Duel (pass-and-play) 2–4 players take turns on one device — same questions for everyone, highest first-try score wins. Reasoning Quest — follow the map → A progression trail through every kit. Clear each stop of real practice, then move on.
