GTAI started with a simple frustration: after years of teaching guitar, there was still no reliable way to give a student instant feedback on their hand posture. Every other part of learning could be explained — but correct fretting technique had to be seen in person.

What began as something to do during lockdown turned into a deeper obsession, working through songs, techniques, and eventually teaching others.
Over the next five years, that turned into real teaching — in-person sessions, plus a website built to give students free personalised video lessons. The AI assistant you use in GTAI today grew out of that same site. Helping students remotely was rewarding, but it made one problem crystal clear: posture couldn't be taught through a screen.
You can explain where to place your fingers. You can record a video. But until a student can see whether their own wrist angle, thumb position, and finger arch are correct — in real time — they'll keep practising the wrong way. Repetition bakes bad habits in. And bad habits make chords sound like they don't belong in music.
Every student hits the same wall. They can memorise where a chord goes on paper — but getting the sound right requires a specific physical technique that's hard to self-diagnose.
Thumb placement, wrist angle, finger arch, and string pressure — all at once, while trying to strum. No app addressed this.
Students practice the same chord hundreds of times — but if the posture is wrong from day one, they're just reinforcing the mistake.
In-person lessons provide this feedback — but they cost money and aren't available to everyone, everywhere.
Watching a tutorial shows you what to do, but it can't see your hands and tell you what you're doing wrong.
After years of thinking about this problem, AI finally made a real solution possible. GTAI uses your webcam and computer vision to analyse your fretting hand in real time — tracking finger placement, posture, and chord formation as you practise.
It's not just a chord diagram app. It's the equivalent of having a teacher sitting next to you, watching your hands, and telling you exactly what to adjust — available any time, on any device, for free.
Provisionally patented. The core method behind GTAI's real-time hand posture analysis and feedback system is currently under a provisional patent application. Five years of teaching guitar — and the specific insight that posture feedback is the missing piece of online guitar education — is what the patent is built on.
