Proof in Motion
An interactive web app that turns famous modern mathematical proofs (Lean- and Coq-verified) into scrollable, step-by-step visual stories with plain-language explanations for curious students and adult math enthusiasts.
Math-curious students, educators, and adult learners who want to engage with cutting-edge theorems without a PhD
- Scrollable proof timeline with diagrams and variable animations
- Plain-language 'so what does this step mean?' recap for every move
- Browse-by-theorem library spanning number theory, geometry, and topology
- Community annotations and discussion threads at each step
The verified Lean confirmation of a gap in Mochizuki's ABC proof made abstract math feel tangible to a wider audience, and LLMs can now narrate formal proofs in plain English cheaply.
Broader math-visualization demand is strong (3Blue1Brown has 6M YouTube subs, Essence of Linear Algebra watched by 'tens of millions'), but the cited HN source itself only garnered 13 points, signaling niche interest in formal-proof news.3Blue1Brown — Influencer Profile, Stats & Rates ↗Essence of Linear Algebra - 3Blue1Brown Classic Math Teaching Video Series ↗
Searches found no direct consumer-facing visual proof-story app for laypeople; jsCoq and Rocq target existing formal-verification users, leaving the curious-student narrative space genuinely open.jsCoq - Use Coq in Your Browser ↗Welcome to a World of Rocq ↗
Math-curious audiences expect free content (3Blue1Brown is free YouTube); even Brilliant, a broad math platform, struggles with annual pricing perception, making a narrow formal-proof niche hard to monetize.How much does Brilliant Premium cost? ↗Brilliant.org Cost: Unpacking Subscription Plans & Value (2024 Guide) ↗
Formal verification (Lean/Rocq) is a durable trend with growing libraries, but casual interest in any single proof is event-driven (e.g., the Mochizuki/ABC moment) and unlikely to sustain steady long-term traffic.
Mapping Lean/Coq tactic trees to plain-language narrative is non-trivial; existing tools (Manim, jsCoq) help, but auto-narrating formal proof steps accurately for a lay audience remains a heavy engineering + ML problem.jsCoq - Use Coq in Your Browser ↗
