Show HN: Lisora – quizzes/reflection prompts to YouTube to improve retention

3 months ago 6

I’ve always struggled to retain information from long-form YouTube videos, especially when passively watching tutorials or explainers. I’d finish a 20-minute video and realize I couldn’t recall much of what I just saw.

So I built Lisora which is a minimal tool that takes a YouTube video and automatically inserts short quizzes and reflection prompts at regular intervals to encourage active learning. I also added scores and have future plans to make it competitive.

You don’t need to install anything or sign up just paste a YouTube link and hit go. It works best on educational or lecture-style content.

It’s still in early MVP stage the quiz logic is simple, and the reflection model is rule-based for now. But I’m planning to:

Make the prompts more intelligent using semantic chunking

Introduce spaced repetition once accounts are enabled

Add retention analytics

Would love any feedback on:

UX flow / onboarding

Technical critiques

Ideas for making learning more interactive

Thanks in advance!
