Live chord scoring
Play along and the app listens through the mic while selected song parts are muted. Headphones help reduce background sound reaching the microphone.
Learn the songs you actually want to play.
Paste a YouTube link or pick a song file. Guitar Mentor finds the chords, splits out the guitar and slows it down until your hands catch up. Then it teaches you the rest, with a tuner that listens, guided lessons, exam-grade paths and an AI coach.
Free to download. Pro is $35.99 a year, with a 3-day free trial.

Chords come from an AI model. Treat them as a strong first draft and trust your ears.
Lessons that start where your hands are.
Pick a path for acoustic, electric, blues or theory and take it one step at a time. When an exercise needs to hear you, the app listens through the mic. If it isn't sure what you played, it tells you, instead of guessing.
- Guided learning paths. Setup lessons and the first three playing lessons of every path are free. Free
- Graded sheet music from Initial to Grade 8, with Initial free.
- Music theory you can see on the fretboard.
- Streaks and XP that reward showing up, not tapping through.
Working towards a grade?
Paths built from the published Trinity Rock & Pop, Rockschool and ABRSM guitar syllabi, with our own practice material. Guitar Mentor isn't affiliated with or endorsed by these boards, and you'll still want the board's own books.

Questions players ask
Is Guitar Mentor free?
Yes. The tuner, metronome, Chord Lab, ear training, the first lessons of every path, Initial-grade sheet music, a starter song and 3 PlugAI chats are free. Pro adds song import, the full stem mixer, every lesson and grade, live mode, export and more PlugAI chats, subject to daily limits.
How does importing a song work?
Paste a YouTube link or choose an audio file. The audio is analysed in the cloud: it's split into six stems, the beat is found and the chords are detected, then the song opens in the player. Pro includes 30 imports a month, up to 10 minutes each. Chords come from an AI model, so treat them as a strong first draft.
Does the app really hear me play?
Yes. The tuner and listening checks use pitch tracking on your phone. When it isn't confident about what it heard, it says so rather than guessing, and it never gives you a score it didn't measure.
Can it help me prepare for a grade exam?
There are learning paths built from the published Trinity Rock & Pop, Rockschool and ABRSM guitar syllabi, and graded sheet music from Initial to Grade 8. The practice material is our own. Guitar Mentor isn't affiliated with or endorsed by the exam boards, so use the board's official books for your exam pieces.
What is PlugAI?
PlugAI is the coach built into the app. Ask it for a song's chords, a practice plan, help with a lesson or why a progression sounds the way it does. It explains and suggests; your progress is measured by the app, not by the AI.
Does it work on iPhone and Android?
Yes. Get it from the App Store (iOS 18 or later) or Google Play.
How do I cancel Pro?
Subscriptions are managed by Apple or Google. Cancel from your App Store or Google Play subscriptions before the renewal date. If you cancel during the free trial, you aren't charged.
Do you work with music schools?
Yes. Guitar Mentor for Schools runs a whole class from one dashboard. See how it works.
