GTAI LLC is a California-based software company building tools that give guitar students immediate feedback on finger placement — the kind of correction that usually requires a teacher in the room.
Our founder spent five years teaching guitar — online and in person. Every other part of learning could be explained in writing or video. But correct fretting technique had to be seen and corrected in real time. There was no tool that could do that without a human in the room.
"Every other part of learning could be explained in a video — but correct hand posture had to be seen and corrected in person. GTAI is the tool I wished existed."
GTAI uses your webcam and on-device computer vision to analyse your fretting hand as you practise. No video leaves your device. It highlights what’s off and what to try next, right there in the session.
The real-time hand posture analysis method powering GTAI's chord feedback engine is the subject of a provisional patent application filed in 2026. This provisional filing establishes an early priority date for the underlying technology while a full non-provisional patent application is prepared. A provisional patent application does not grant patent protection on its own; it establishes priority while a full application is pending.
