Parenting Behavior Annotator

A browser-based tool for scoring parenting behaviors in mouse videos across seven dedicated timeline tracks (a pooled parenting prediction plus six ethogram codes), frame by frame.

What it does

Built for a collaborating lab's parenting-behavior study, this annotator makes it easy to score maternal and parental behaviors in mouse videos. Load a video, step through it frame by frame, and mark when each behavior begins and ends. Each category lives on its own color-coded timeline track. A pooled parenting prediction track (from the ParentingAll model) sits alongside six manually scored ethogram codes, so model output and hand annotation can be compared at a glance. Annotations auto-save as JSON next to the source video. Everything runs in your browser, with no installation, and your videos never leave your computer.
