How Lull works

For every kids' show, Lull gives you two things: a plain-English rundown of what it's actually about and who it's for, and a Lull rating that tells you how soothing or stimulating it'll really be. Here's how the rating works, and just as much, what it won't tell you.

What you get for every show

A short rundown of the premise, the age it's pitched at, how long an episode runs, and where to watch it, plus a Lull rating from Calm to Intense. The point: know what you're putting on before you press play, so bedtime gets something soothing and the rainy afternoon gets something livelier, on purpose, not by accident.

What goes into the rating

The rating comes from the episode itself, not a vibe or a guess. Lull measures the signals that actually drive how stimulating a show feels and works them into a single calm-to-intense score. The method is our own, and we keep sharpening it. What you get is one honest number, not a hunch.

Five calm levels

We show the 0–100 score as one of five buckets. We keep the display this coarse on purpose: it's about all the inputs can honestly distinguish, and it avoids implying a precision we don't have.

Calm 0–20 bedtime-friendly

Gentle 21–40 soft and slow

Moderate 41–60 a middle gear

Lively 61–80 bright and busy

Intense 81–100 high activation, not for wind-down

Measured vs. estimated

This is the honest core of Lull, and every card says which one it is:

✓ Measured: the rating was computed directly from the actual episode video. Real, instrumented numbers, not a hunch.
Estimate: for shows we can't yet measure, an expert estimate anchored to known benchmarks (the calmest and most intense shows) and placed by reputation, format, and reviews. A judgment, clearly labeled as one.

Why isn't everything measured? Because measuring a show means processing its video, and we won't bypass the copy protection on streaming services to do it. That's illegal, and no foundation for a product parents should trust. Measured coverage grows from licensed and public-domain sources, one show at a time.

What parents add

Alongside the Lull rating, every show has a Parent vote, a community calm-to-intense slider. We keep it deliberately separate from the rating and never blend the two: an objective measurement on one side, lived experience on the other, like a critic score next to an audience score.

What this isn't (yet)

We'd rather tell you the limits than oversell:

Estimates are informed judgments, not measurements; they carry real error bars.
The rating model is still young. We're validating and refining it against real parent feedback over time.
Today most of the catalog is estimated. The honest badge tells you which scores you can lean on hardest.
