PIEK (2025): AI-powered guitar tutor for beginners by Haneul Kang

In the evolving landscape of digital self-learning, the pursuit of hobbies, especially music, has become more than a pastime. It is a form of self-expression and an act of creative ownership. As barriers to traditional music education persist, PIEK offers a compelling solution. It aims to rewire the way people learn guitar using design, data, and AI.

The Shift in Learning: From Information to Expression

Over the past five years, the rise of online learning has reshaped how individuals approach self-improvement. But in 2025, the focus has shifted. People are learning to live better, not just work better. From fitness to film photography, pottery to piano, hobbies have become deeply personal rituals. Among these, guitar playing stands out as both culturally embedded and emotionally resonant.

Yet, the tools for learning remain fragmented. Video lessons cannot correct poor posture. Apps cannot evaluate form. In-person instructors, while effective, remain inaccessible for many due to cost.

PIEK addresses this challenge not with more content, but with smarter systems.

Introducing PIEK: Precision in the Palm of Your Hand

PIEK is a compact, AI-powered learning system that clips onto your guitar and analyzes your playing in real time. It captures motion, posture, tempo, and form, then delivers intelligent, actionable feedback through an intuitive mobile app. With PIEK, practice is no longer trial-and-error. It becomes structured, intentional, and measurable.

Whether you're a beginner avoiding bad habits or a self-taught guitarist refining technique, PIEK transforms uncertainty into progress.

Product System: Designed for the Way You Learn

PIEK SOLOThe entry-level model clips directly to the guitar’s headstock. With a front-facing camera, IMU sensors, and vibration detection, SOLO tracks picking force, chord transitions, and hand posture. Its tuner-like form factor is lightweight, unobtrusive, and easy to use.

PIEK DUOFor more advanced users, DUO stands on a tabletop and uses a wide-angle camera to monitor both hands. It requires no contact with the guitar and captures posture, finger accuracy, and rhythm consistency. Its intelligent LED strip doubles as a visual metronome, responding to tempo, groove, and timing. DUO is not just a monitor, it is a rhythm-aware feedback system.

PIEK APPThe PIEK app ties everything together. It logs your playing sessions, tracks tempo and accuracy, and surfaces personalized insights. With features like heatmaps, mistake analysis, and routine recommendations, the app empowers users to reflect, adjust, and improve continuously.

System Thinking: Dual-Hand Feedback in Real Time

Used together, PIEK SOLO and DUO offer a dual-angle tracking environment. This setup captures both fretting and strumming movements, delivering comprehensive feedback across technique, form, and musicality. The system encourages balanced development and deeper muscle memory by treating both hands as integral to the learning process.

This level of precision is not achievable through traditional lessons or video tutorials.

Design that Learns from You

PIEK’s strength lies in its design philosophy. The hardware is minimal. The intelligence is embedded. The feedback is immediate but never overwhelming. The user experience stays focused on learning without distraction.

Practice becomes quieter, clearer, and more deliberate.

Relevance in a New Era of Hobbies

Post-pandemic, a wave of new musicians emerged. Many sought connection, creativity, or moments of personal calm. That surge also exposed the limitations of current learning tools. PIEK addresses that space directly, not by mimicking instructors, but by designing a smarter practice environment.

For the first-time player and the experienced enthusiast alike, PIEK becomes the missing piece in a fragmented journey.

At NIWWRD, we view PIEK not as another gadget, but as a systems-level rethink of what modern music learning can look like. It is where form meets feedback, and where learning becomes design-driven.
