Only me

Arena turns the real world into a math boss fight. Snap a staircase, a ramp, a shadow — Meta AI (muse-spark-1.3 vision) reads the photo and forges a calculus boss from it: sequences from steps, derivatives from slopes, integrals from curves. The same engine scans exam photos too: it decomposes handwritten attempts, maps each mistake to one of 50 skills, and traces the root cause to the earlier chapter never mastered. Every weakness spawns a 4-hour Boss — 5 isomorphic questions, escalating difficulty — fought solo or co-op with a friend. Every AI-written answer is re-verified by a deterministic checker before it can spawn; rejected questions are discarded and regenerated. Problem solved math feels abstract because it lives on paper. Arena pulls it out of the world around you, finds the true gap in your foundations, and makes patching it feel like play.
