From a channel search to a parent guide
One repeatable workflow, with the useful answer shown as soon as there is enough evidence.
Confirm the channel
We resolve the exact YouTube channel ID so spelling variations and aliases do not create duplicate creators.
Choose a useful sample
We select a mix of recent and popular long-form videos. Shorts are excluded so every rating has enough context.
Review each video
A pinned model classifies the available spoken-word evidence using one consistent, parent-focused rubric.
Score for each age
The same observations produce separate results for ages 5–7, 8–10, 11–13, and 14–17.
Eight signals, weighted by seriousness
Categories are not treated equally. Mature and sensitive topics, violence, sexual content, and risky behavior have greater influence than commercial pressure.
Useful quickly. More certain with time.
Parents do not have to wait for every video before seeing a carefully labeled first result.
Early estimate
After two completed video reviews, we show a limited-confidence score while work continues.
Stable assessment
We target six long-form videos and require at least four usable reviews before publishing the parent guide.
Deeper check
Up to twelve long-form videos may be reviewed in the background when the first sample is mixed or inconsistent.
What we do and what we do not claim
Public content is evidence, never instruction
Titles, descriptions, and spoken content are treated as untrusted data. Creator text cannot alter the task, scoring rules, or model instructions.
We cannot see everything
We do not claim to assess unseen visual-only material, private or deleted uploads, comments, live chat, or every video on a channel.
Review dates stay visible
Every published assessment shows when it was reviewed. Pages older than one year are clearly labeled so parents know that newer uploads may differ.
Evidence is versioned
We store structured video findings, model and scoring versions, sample size, date, and confidence so changes can be explained and rescored.
Screen Signals is for adult parents and legal guardians. It is a decision-support tool, not a substitute for a parent’s knowledge of their child or a review of every upload.
