Theorem Forge
An AI proof-writing coach for discrete math and intro-to-proofs students that serves targeted exercises, escalates hints only when stuck, and gives line-by-line feedback on draft proofs to flag where the logic breaks.
undergrad CS/math students wrestling with their first proof-based course
- Adaptive exercise queue spanning direct, contradiction, contrapositive, and induction techniques
- Line-level feedback on a student's draft that pinpoints where a step stops following logically
- Hint ladder that escalates one rung at a time based on the actual stalled step, not a generic nudge
- Mistake-pattern dashboard showing recurring weak moves (e.g. misuse of 'for all' vs 'there exists')
A front-page HN post about an RPG-flavored proof-practice game is re-igniting attention to how painfully few engaging tools exist for the course that weeds out most CS majors — Introduction to Proofs.
Confirmed HN signal (Dungeon Proof Crawler ~50 points) plus multiple existing AI discrete-math helpers and an Introduction to Proofs hub on Varsity Tutors, but audience is niche (single weed-out course, ~1 semester).Dungeon Proof Crawler: learn how to write proofs with RPG | Hacker News ↗Introduction to Proofs | AI Practice & Tutor | Learning Hub ↗
Existing tools split between homewor-solving helpers (edusolver, StudyMonkey, ThetaWise) and competition-math AI (Intellectual Shield); none combine escalating hints with line-by-line draft-proof feedback aimed at intro-to-proofs students.Intellectual Shield — AI Math Proof & Competition Tutor ↗Free AI Discrete Mathematics Homework Helper - Step-by-Step Discrete ↗
Working AI-tutor pricing exists (MathGPT, Intellectual Shield, Khang etc.), but undergrads are price-sensitive and most successful models are B2B/school-seat; freemium likely required.Low-Cost Responsible AI Learning Solution and AI Math Tutor | MathGPT.ai ↗Best AI Tutor for Students in 2026: Free and Paid Options Compared ↗
Intro-to-proofs is a permanent weed-out course across CS/math curricula, and AI-tutoring category is structurally growing rather than fad-driven.Practicing Proofs MAT246 Handouts ↗
Generating line-by-line logical feedback on natural-language proofs is a known weak spot for current LLMs (hallucinating valid steps, missing subtle gaps); a non-trivial research-style engineering effort, not a weekend build.11 Best AI Math Tutoring Tools 2026 (Step-by-Step Help) ↗
