Bite-sized AI mastery

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Learn how AI actually works. Mental models, not tool tutorials. 100% free, no subscription. Offline. No ads. Stop prompting. Start thinking. Most people learn which buttons to click; ModelMind teaches you how the machine actually works. Tools change every quarter, but mental models compound for life. The ModelMind Edge: Zero Shortcuts: No magic prompts. Understand next-token prediction, scaling laws, and task decomposition. Master the Failure: Identify why AI hallucinates and learn to triage the five ways LLMs break. True Collaboration: Move from giving orders to high-level partnership. Completely free. No ads. No subscription. Works entirely offline. How it Works: Bite-sized, interactive challenges let you sort, match, and triage your way to intuition. Every lesson, unit, and test is unlocked from day one, with no limits and nothing to pay for. Build the understanding that transfers, not the shortcuts that expire. Available in English and Korean.

Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

ModelMind is now 100% free. Every lesson, unit, and test is unlocked from the start, with no limits and no subscription. We removed the hearts system entirely, so you can learn as much as you want, whenever you want. We also fixed a rare crash some people saw on the first launch after installing.
