Our story

We're building the AI brain for guitarists.

Most music apps bolt AI on as a feature. We started the other way around — designing Guitar Mentor, ground-up, around an intelligence that actually understands music. We call it PlugAI.

PlugAI
Meet PlugAI

The mind behind
the music.

PlugAI is our purpose-built music intelligence. It reasons step-by-step in a visible thinking mode, calls real tools to fetch lyrics and chords, aligns them, and explains theory like a patient teacher — not a generic chatbot wearing a guitar costume.

From "find the chords for California Dreamin'" to "why does this progression sound sad?", PlugAI is the thread running through every screen of the app.

Ground-up music intelligence

One song in. Everything out.

Drop in a track and our cloud pipeline turns raw audio into something you can actually play — in a single run.

Ingest

Any song, imported or from your library.

Separate

Six clean stems via source separation.

Detect

Chords & key from a trained model.

Align

Lyrics & MIDI, synced to the beat.

Play

Practice-ready in the player, instantly.

Under the hood

Cutting-edge, end to end

Agentic reasoning

PlugAI plans, calls tools, and streams a visible thinking trace before it answers — real tool-use, not autocomplete.

Music ML pipeline

Source separation, a trained chord-recognition model, beat tracking and lyric alignment running in the cloud.

Native performance

A real-time tuner kernel and a Metal-accelerated fretboard, rendered natively for buttery 120fps interaction.

On-device + cloud

Latency-sensitive audio runs on-device; heavy analysis scales in the cloud. You get speed where it matters.

Private by design

Sign in with Apple, your practice data stays yours, and analysis quotas are enforced fairly server-side.

Always improving

An adaptive intelligence layer spots your weak spots and shapes tomorrow's practice around them.

What we believe

Built by players, for players

01Playing first

Every feature has to make you a better player faster. If it doesn't get you back to the guitar, it doesn't ship.

02AI you can see

No black boxes. PlugAI shows its work — the steps, the sources, the reasoning — so you learn while it helps.

03Craft in the details

From a string that vibrates when you tap it to a needle that locks green in tune, the small things are the app.
