Show HN: Visualizing when you forget what you learn

https://flashmind-app.vercel.app/
1•rogimatt•3h ago
Hi HN,

I kept forgetting things shortly after learning them, so I built a small tool to visualize memory decay over time.

The idea is simple: instead of reviewing blindly, you can see when a memory is about to drop and review at the right moment.

You can add content manually or from links (articles, videos), and the tool schedules reviews automatically.

This is an early beta and I’m mainly looking for feedback, especially on the learning model and UX.

Link: https://flashmind-app.vercel.app/

Happy to answer any questions or explain the technical choices.
