Measured, not curated by opinion
Comprehensible input, with numbers attached
We read each video’s actual subtitle track and score it on vocabulary load and speaking pace, then rank whole channels by what a learner really meets — so “is this at my level?” has an answer you can check, instead of a recommendation you have to trust.

How to read it
- The score orders content; the band labels its vocabulary load. They measure different things, so a band is never derived from a score. A fast video with common words can be harder than a slow one with rare words.
- Scores compare within a language, not across languages. Pace is normalised per language, vocabulary is not.
- Labels are computed, not hand-annotated. The sample is a curated set of channels, not a random slice of YouTube.
