Everything you need to get the most out of ModelMind.
ModelMind teaches you how AI actually works through short, structured lessons and interactive exercises. Each course is broken into bite-sized lessons you can complete in a few minutes.
Exercises test your understanding as you go. Seven different exercise types keep things varied: multiple choice, sorting, sequencing, matching, triage, comparison, and decision trees. Everything is graded instantly on your device.
The app works entirely offline after download. No internet connection required to learn.
All 21 courses are completely free. Every lesson in every course is accessible to all users at no cost.
Free users get 5 hearts per day. Each incorrect answer costs one heart. When you run out, your progress pauses until hearts regenerate. Hearts refill at a rate of 1 per hour, and fully reset to 5 at midnight.
This system encourages thoughtful engagement. Take your time with each exercise, and your hearts will last.
ModelMind Plus gives you unlimited hearts, so you can learn at your own pace without waiting for refills. All 21 courses across all four paths (Foundations, Building, Thinking, and Creating) are free for everyone. Plus simply removes the heart limit so you can learn without interruption.
Subscriptions are managed through the App Store (iOS) or Play Store (Android). You can subscribe, change your plan, or cancel at any time through your device's subscription settings.
Try closing the app completely and reopening it. If that does not help, clear the app cache in your device settings or uninstall and reinstall. Your progress is preserved if you are signed in with cloud sync enabled.
If you were not signed in, your progress was stored only on your device. To prevent this in the future, create an account and enable cloud sync. This keeps your learning data backed up and accessible across all your devices.
Subscriptions are managed by the App Store or Play Store, not by ModelMind directly. To cancel, open your device's subscription settings:
Hearts regenerate at a rate of 1 per hour, up to a maximum of 5. All hearts fully reset at midnight. If your hearts appear stuck, try closing and reopening the app. ModelMind Plus subscribers have unlimited hearts and will not see the heart counter.
