🎯 How It Works
- Difficulty Scoring — Comprensi overlays a score (0–100) on every video thumbnail once enough data is available. The score is based on community comparisons that are processed with TrueSkill for robust estimates.
- Time Tracking — While you watch, Comprensi securely logs how many minutes you spend on videos in your chosen language(s). A weekly and all‑time tally is available in the popup so you can stick to your input goals.
- Light Nudges — After finishing a video you may occasionally see a super‑short prompt asking which of two videos was easier. Your answer sharpens future difficulty scores for everyone.

❓ FAQ
I don’t see any difficulty scores yet. Is something wrong?
Scores appear only after enough comparison data has been gathered to make a confident estimate. Early adopters may see fewer scores while the system warms up. We’ve pre‑seeded Spanish with data from https://comprensi.com, but most other languages will need a little time to populate.
Where is my watch‑time data stored?
All time‑tracking happens locally in your browser. Nothing is uploaded unless you explicitly opt into sync features (coming later). Your privacy is paramount.
Does Comprensi work on mobile YouTube?
At the moment, Chrome extensions only run on desktop browsers.
