NoteWorthy is an offline transcription and practice studio for guitarists — and a handy toolkit for any musician who learns music by ear.

Load your own video or audio file, slow it down, loop the hard parts, watch the waveform, and drop time-stamped annotations exactly where the notes fall. As you work, NoteWorthy turns what you hear into readable guitar tablature you can play back, refine, and export. Whether you learn songs by ear, work out solos, capture riffs, or study chord changes, it all lives in one app: transcription, an interactive fretboard, tab and sheet rendering, a tuner, a metronome, ear training, and guitar lessons.

Built around VexTab — simple, text-based guitar notation:
NoteWorthy is built on VexTab, a compact text syntax for writing guitar tab and standard notation. Every note, chord, bend, hammer-on, slide, rest, and time signature you add becomes plain VexTab text and is rendered into clean tab and notation. Build tabs visually with the fretboard and let NoteWorthy write the VexTab for you, read and copy the generated tab text at any time, and learn a portable, human-readable notation format instead of a proprietary file. Built-in syntax help explains the VexTab tokens (for example 5h7/1 for a hammer-on or 5s7/1 for a slide) whenever you need them. Everything separated by spaces and fret are in front of a forward slash with string behind the slash. Multiple notes on the same string are optionally written as 2-4-2-5/2.

Everything happens on your device. No signup. No account. No internet required. No cloud storage. No tracking. Your files, annotations, and transcriptions stay with you — at home, in the practice room, backstage, or on the road.

Recommended workflows:

Learn by ear — Use the Pluck tab for focused listening. Slow down the song, scrub through the waveform, and loop the exact section you want to study: riffs, solos, rhythms, vocal lines, or bass parts.

Transcribe — Use the Annotate tab with the built-in fretboard to add notes, chords, bars, rests, time signatures, and text markings while listening. Annotations are placed on the timeline and rendered into guitar tablature.

Hear the hard notes — Use local frequency detection to analyze tricky sections. It can suggest notes around a selected moment or help resolve placeholders: a best-effort assist that you review, correct, and refine manually.

Cleaner tabs — Add bar lines first, then enable the grid before adding notes to align annotations to musical timing and improve the generated tab. You can also place every annotation manually for exact control.

Uncertain passages — Use placeholders to mark notes you are unsure about and return to later, resolving them manually or with detection.

Main transcription tabs:

Pluck — Focused listening with video or audio playback, waveform navigation, speed control, looping, and a read-only timeline.

Annotate — The main workspace: fretboard entry, chord groups, bars and rests, placeholders, waveform zoom, section looping, and timing refinement.

List — Review every annotation in order: edit entries, filter by type, mark items complete, lock finished annotations, and stay organized.

Sheet — Render your transcription as tablature, inspect the underlying VexTab text, play it back with MIDI, and export the result.

Info and Settings — App information, privacy details, VexTab syntax help, and annotation legends. Customize fret count, bar offset, detection sensitivity, tab grouping, theme, and tuner style.

Additional tools:

Tuner — A microphone-based tuner.

Metronome — Time signatures, BPM, and sound, vibration, or flash modes.

Ear Training — Intervals, chords, scales, and combinations.

Licks — Save your own licks, or request licks to be added to the app library in a future version.

Lessons — Soon coming.

Privacy:
NoteWorthy needs no account and does not track you. Your media, annotations, practice activity, and transcription data never leave your device.
