Why TrueLightSigns

More than videos. Actual practice with feedback.

Passive watching doesn't build real skill. TrueLightSigns turns every session into active practice with corrective guidance.

Real-time webcam grading

MediaPipe watches your hand and grades every sign with a live confidence score and gentle hints.

A-Z alphabet trainer

Walk through the ASL alphabet one letter at a time. Hold the sign for a moment and advance to the next letter.

Random letters, 60-second timer, bonus points for speed. A fun shareable way to build fluency.

Streaks that stick

Daily streaks, longest runs, and simple milestones — quietly motivating, never annoying.

Progress dashboard

Mastery heatmap, weekly activity, and your weakest letters so you always know what to practice.

Private by default

All vision runs in your browser. Your webcam video never leaves your device.
