Reason
For students & instructorsPractice thinking, not just answering
A critical-thinking trainer for the AI era. Reason gives students structured practice evaluating claims, weighing evidence, and building arguments — with an AI that pushes back, plays devil's advocate, and asks the next hard question instead of handing over answers.
“Here's a claim from this week's news. What would you need to know before you believed it?”
The more capable AI gets, the more valuable the skills it can't exercise for you become. Reason makes practicing them as routine as homework.
Argument mapping
Break an argument into claims, evidence, and assumptions on a visual canvas — and see exactly where it holds up or falls apart.
A sparring partner, not an oracle
The AI takes the other side: it challenges your reasoning, plays devil's advocate, and won't concede without evidence.
Fallacy drills
Short, spaced exercises in spotting weak reasoning — from cherry-picking to false dilemmas — drawn from real examples, not textbook ones.
Evaluate real sources
Practice on articles, studies, and social posts: trace claims back to sources and decide what it would take to make them credible.
Steelman first
Before critiquing a position, students state its strongest version — a habit that transfers to essays, seminars, and civic life.
Instructor insights
See how students reason, not just what they conclude — where a class gets stuck and which skills need another rep.
