Hi HN! I've built Learntime, an open source learning tool that combines un-prompted active recall with AI mentor support to help you retain information more effectively.

Key features:

- Un-prompted recall: Challenge yourself to explain entire topics without cues, actively reconstructing knowledge instead of relying on flashcards

- AI mentor support: Dynamic hints help identify gaps and guide learning without giving away answers

- Context-rich learning: Maintains relationships between concepts instead of isolated facts

- Spaced repetition algorithm: Optimizes review intervals based on recall performance

- Quick Quiz: Targets specifically what you've struggled with previously

I built this because while there are many tools for acquiring information (YouTube, MOOCs, etc.), few focus on evidence-based retention techniques.
