Use Cases

Illustrative Use Cases

I failed my Philosophy 101 midterm despite watching 15 hours of YouTube. After using Recall for 2 weeks, I aced the final. The concept matching is scary accurate. I could see exactly which topics I was missing.

I'm a self-taught developer taking online courses. Recall helped me actually retain what I learned instead of just watching videos and forgetting. The spaced repetition is a game-changer.

I finally have a daily review habit. The unlocks feel rewarding — like leveling up in a game. I can see my progress: 23/67 concepts mastered. It's addictive in the best way.

I uploaded my Economics syllabus and processed 8 YouTube videos in one afternoon. Within 60 seconds, I had flashcards matched to my course. This would've taken me 10 hours to do manually.

Sarah L.

Economics Student, Canada

The gap analysis feature is incredible. Before my exam, it told me: 'You're missing: Social Contract Theory, Virtue Ethics.' I watched 2 videos, reviewed the flashcards, and those were literally on the test.

I'm learning Japanese through YouTube videos. Recall extracts vocabulary and grammar concepts automatically. I review 3 minutes every morning and my retention has skyrocketed.
