How it works

One extension. Three learning superpowers.

LearnFlow detects your real-time emotional state from your webcam and responds instantly — anchored to the exact timestamp in the video you're watching.

😕
Confused detected

Plain-language breakdown

A step-by-step explanation of the concept playing right now, tailored to your level — not a generic Wikipedia summary.

😤
Frustrated detected

Micro-quiz to reset

A quick 3-question quiz on the current topic. Getting answers right resets frustration and builds real confidence.

😐
Bored detected

Surprising fun fact

A real-world application or mind-bending connection that makes the dry topic suddenly feel worth knowing.

Features

Built for serious learners.

Camera Mode

Fully automatic — face-api.js runs in the browser with zero video leaving your device. Your face stays yours.

Manual Mode

No camera? No problem. Action chips let you request Summary, Quiz, Fun Fact, Breakdown, or Encourage Me on demand.

Privacy-first

Face detection runs entirely on-device. Only the video title, transcript excerpt, and detected emotion go to the LLM — never your camera feed.

Session Analytics

A heatmap of when and how often each emotion fires per session. See exactly where a video lost you.

Streak Tracking

Quiz score streaks build across a session, rewarding you for actually retaining what you watch.

Sensitivity Control

Low / Balanced / High presets with per-emotion threshold sliders and configurable cooldowns from 30s to 5 min.
