LOCAL TEACHING CUES ASSISTIVE, NOT PRESCRIPTIVE

Session cues will appear here after analysis. Treat them as prompts for reflection, not measurements of learning.

Movement and audio activity are rough context signals—not measures of attention, understanding, emotion, or individual performance.

PRIVACY & LIMITATIONS

Designed to stay on your device.

Video and audio are sampled locally by your browser. The original media is not uploaded or saved. Session summaries, participant codes, and check-in times are kept in this browser's local storage.

This starter does not identify faces, detect speech content, or infer a learner's attention or emotional state. Visual movement and audio energy are limited proxies. Teaching cues are simple rules-based prompts, not an AI model or professional advice.
