Ten Ways to Train
Each mode targets a different critical thinking skill. Together, they build a complete reasoning toolkit.
Fallacy Flash
Rapid fallacy identification — the core drill. Read a short argument, spot the logical error. Progresses from multiple choice to free-text identification as you advance.
- ▸Spaced repetition scheduling
- ▸Timed challenges at higher belts
- ▸AI-evaluated free-text at Brown+
Steel Man
Construct the strongest version of an argument you disagree with. The single most important skill for democratic discourse.
- ▸AI-scored on charity, evidence & steelmanning
- ▸Real-world policy positions
- ▸Constructive feedback on every attempt
Source Check
Evaluate claims paired with citations for reliability. Learn the evidence hierarchy from meta-analyses down to anonymous social media posts.
- ▸Source reliability scoring
- ▸Claim-source alignment checks
- ▸Missing context identification
Argument Map
Visually decompose arguments into claims, premises, and evidence — then draw the connections. The single highest-impact critical thinking technique (0.70 SD gain).
- ▸SVG argument tree builds as you play
- ▸Identify claims, premises, evidence & assumptions
- ▸AI-scored at Green belt and above
Debate Dojo
Live argument practice against an AI opponent scored on logic, not rhetoric. The signature mode — the reason people tell their friends.
- ▸Structured exchange format
- ▸AI uses fallacies you must spot
- ▸Post-debate scorecard for both sides
Daily Challenge
Same 5-question fallacy challenge for everyone, every day. Compete on score and speed, then come back tomorrow for a fresh set.
- ▸New challenge every 24 hours
- ▸Same questions for all players
- ▸Score + time tracking
Daily Brief
Daily challenge: three news summaries — one has a logical error, one is missing context, one is solid. Identify which is which and explain why.
- ▸New challenge every day
- ▸Streak tracking
- ▸Pre-built scenarios — no API needed
Socratic
Examine common beliefs through Socratic questioning. Read a thesis, then identify which of four probing questions most powerfully challenges the claim.
- ▸5 chains across meritocracy, tech, democracy, speech & tradition
- ▸Reveals hidden assumptions and uncomfortable conclusions
- ▸Expected insights and follow-up questions after each round
Civic Check
Read real policy proposal summaries and identify what a bill actually does — versus what it claims, how it's commonly misread, or what its opponents say.
- ▸15 scenarios across housing, education, tech, health & energy
- ▸Fictionalized bills based on real legislative patterns
- ▸Builds policy literacy and close-reading skills
Real World
Practice with real-world scenarios: spot fallacies in political claims, evaluate media sources, and steelman controversial positions. Mixed-format rounds keep you sharp.
- ▸30 scenarios across fallacy spotting, source evaluation & steelmanning
- ▸Anonymized examples from AI policy, climate, healthcare & economics
- ▸Score tracking with streak counter
