MindBend

A daily adaptive reasoning puzzle app that gets harder as you improve, inspired by the same puzzles frontier AI still struggles to solve.

Target user

Adults and students who want a brain-training habit beyond Sudoku, Wordle, and NYT Games

Features
  • One fresh grid-pattern reasoning puzzle each morning with adjustable difficulty tiers
  • Streak tracking, performance curves, and a weekly "hard mode" challenge
  • "Show your reasoning" walkthroughs that teach logic rather than just revealing answers
  • "Beat the AI" mode where you race to solve puzzles faster than popular LLMs can
Why now

ARC-AGI is publicly tracked as a frontier reasoning benchmark; consumer curiosity about AI limits is high and the leaderboard keeps the topic alive.
