CaChink — guitar tabs, tuner, chords & lessons in your browser

CaChink is a mobile-first browser guitar suite. Every tab is playable: chord diagrams strum on tap, and the ASCII tab renders to synthesized audio in the song's own tuning and capo. The mic tuner pays you a coin sound when you hit pitch. Nothing to install, everything runs on your device.

Learn — swipeable lesson decks

• Rhythm — Feel, Time & the Comp (Fundamentals) — The right hand is the instrument. Eight grooves you can play against — straight, swung, four-to-the-bar, Charleston, sixteenths, the One — with the mechanism behind each one.
• Jazz I — The ii–V–I Toolkit (Intermediate) — Six progressions that between them cover most of the Real Book — plus what to play over each one.
• Jazz II — Rhythm Changes, Coltrane & Modal (Intermediate +) — What to play when the ii–V–I stops being enough: fast turnarounds, three tonal centres, and one chord for sixteen bars.
• Funk — Vamps, Stabs & the One (Intermediate) — Funk harmony barely moves — so everything happens in the right hand. Five grooves, why each one sits, and how to solo when nothing changes.

Tools

• Chord Finder & Library — tap a fretboard or play into the mic; CaChink names the chord.
• Tone Studio — stack virtual pedals, dial in classic guitarist tones, save a favorite that colors all playback.
• Transcribe — play a riff live or upload audio, get an editable playable tab back. All on-device.
• Tuner — needle shows cents off; hold it in tune and cachink, you get paid.
