What's Inside

A thin, flexible circuit board that hugs your fretboard

144 Micro LEDs

APA104-1010 RGB addressable LEDs — 0.3×0.3×0.1mm each. One per fret per string. Individually controllable colors.

144 Touch Pads

Capacitive touch sensors at every LED position. Detects finger placement with millisecond precision.

ESP32-S3 Mini

Dual-core 240MHz processor with WiFi. Drives all LEDs + touch sensors. Connects to the AI cloud backend.

Loaded With Intelligence

Hardware + AI working together to teach you guitar faster than anything else

Micro RGB LEDs

Ultra-tiny APA104-1010 addressable LEDs (0.3×0.3×0.1mm) — one on every fret of every string. They light up to show you exactly where to press.

Touch Sensors

Capacitive touch pads at every fret position detect your finger placement in real-time, so the system knows exactly what you're playing.

ESP32-S3 Mini Brain

Powerful ESP32-S3 Mini microcontroller drives all LEDs and touch sensors via WiFi. Streams data to the cloud AI backend in real-time.

AI Audio Analysis

Records your playing through an audio interface, sends it to our AI model, and gets instant feedback on what you did wrong — note by note.

AI Tab Generator

Upload any song — our AI creates accurate guitar tabs automatically. No more searching for tabs online.

Personalized Learning

The AI remembers your playing style — short fingers, aggressive strumming, weak pinky. It adapts lessons specifically for YOU.

Setup in 60 Seconds

No soldering. No modification. Just peel, stick, connect, and play.

01

Peel & Stick

The flex PCB strip is self-adhesive. Just peel off the backing and stick it along your guitar's fretboard. Works on any guitar — acoustic, electric, classical.

02

Connect via WiFi

Power on the ESP32-S3 module. It creates a WiFi connection to the TabHero app on your phone or PC. Setup takes under 60 seconds.

03

Pick a Song & Play

Choose any song — the LEDs light up on your fretboard showing you exactly where to press. Start slow, and the system speeds up as you improve.

04

AI Tracks & Adapts

Touch sensors + audio analysis track your accuracy. The AI identifies weak spots, focuses practice there, and builds a learning path custom to you.

Why TabHero Wins

Competitors sell you a whole new guitar. We upgrade the one you already love.
