Fret
See exactly which notes to play, live on the fretboard
Fret launched on May 7, 2026.
What it does
Most guitar learning keeps theory separate from the instrument. Fret puts it back on the neck. Pick a lesson → a backing loop starts → every scale-safe note lights up on the fretboard. Mic input detects when you hit them. Earn stars by landing on strong chord tones. Also has a free scale explorer: choose any scale in any key, see it mapped across the full neck, and let the mic match your playing to the closest scale in real time. Free. No download. Works in any browser.
Build a daily guitar practice habit with guided loop lessons, live key detection, scale exploration, and an interactive fretboard for guitar and bass.
Fret is a free browser-based guitar coach and song key finder. Listen to music, detect its key and scale, then see the matching notes on a guitar fretboard or piano keyboard. Enable JavaScript to use the app. Beginners who want structure and experienced players who want a fast fretboard reference. Lessons work on any guitar — standard, bass, 7-string, or dropfrom fretboardonline.com

I created a game to memorize the fretboard2023 · fretboardfly.com · ▲258Hey guys I've been playing the guitar for many years but I felt like I had hit a wall and wasnt making progress. One of the things I realized was holding me back was unfamiliarity with the fretboard. I'd often find myself in situations like “Uhh…Where’s the C# here?” “Where’s the flat-3rd of this root on the 4th string?” “Sure would be nice to know the closest min7 triad shape to play over here..” I tried memorizing the fretboard the obvious way but it extreeemly boring for me. Being a developer, I decided to turn it into a game. I'd love for you guys to try it out and let me know what you…

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
