One score,
four ways to read it

Tablature, standard notation, both at once, or a piano roll. Switch whenever you like — and every one of them is a real editor, not a preview.

Tablature

Frets and strings, with the rhythm properly engraved: stems, beams, dotted notes and rests.

Standard notation

The staff, note heads at their real pitches. Treble 8vb for guitar, bass clef for bass.

Staff + tab

Both stacked on a shared layout, the way guitar music is normally engraved.

Piano roll

Notes falling towards a keyboard. Split the hands into two voices and work on one at a time.

Features

Everything you need to practise,
in one app

Stop juggling apps. The editor, the player, the practice tools and your library live in the same place.

A real editor

Type on the keyboard, tap on the score, or plug in a MIDI keyboard. Copy, paste and undo work in all four views.

Audio → Tab

Drop in an MP3 and get an editable tab. Or read the chord grid of any recording — that one is free, unlimited, and computed on your own device.

Play together, live

Create a room, share a six-character code. Playback stays in sync for everyone on a shared clock, and voice chat runs in instrument quality — nothing eats a sustained note.

Work the hard bar

Loop a range of measures and keep it with the score. The speed trainer raises the tempo pass after pass, up to the real one.

Your library, and your files

Scores stay private, sync across your devices, and every save is a version you can go back to. Import Guitar Pro (.gp, .gp3, .gp4, .gp5), MIDI, MusicXML and AlphaTex.

Tuner, metronome & more

Chromatic tuner, metronome and tap BPM dock beside the score and keep running while you play. Plus a scale reference and a piano.

Audio to tab

From a recording
to an editable tab

Cesure listens to what was played and writes it down. It composes nothing: what you get is a draft to correct, play and export.

1
Drop in the audio

MP3, WAV or M4A — a phone recording, or a bounce from your DAW.

2
It gets transcribed

Pitch and rhythm are detected note by note, then laid out on the fretboard the way a guitarist would finger them.

3
Edit & export

An editable tab to refine, loop, play and export as a printable PDF.

AI transcription (BasicPitch) runs on our servers: 3 free conversions a month, unlimited with Pro. Chord detection is a different thing — it is computed entirely on your device, free and offline.

FAQ

Questions, Answered

Is Cesure free?

Yes. The editor and its four views, the player, playing together in real time, the tuner, the metronome and the BPM detector are all free. The free tier keeps 3 saved scores — with unlimited version history — and includes 3 AI transcriptions per calendar month; an unlimited library, unlimited transcription (every conversion runs on our servers) and MIDI, MusicXML, AlphaTex and WAV export are part of Cesure Pro.

Do I have to install anything?

No. Cesure runs in your browser, on desktop and mobile. Android and iOS apps are available if you prefer native; the web app is the full app, not a preview.

Do I need an account?

Not to start — open the app and edit right away. An account saves your scores, syncs them across your devices, and is required for AI transcription and for hosting a room.

Can I edit the staff and the piano roll, or only the tab?

All four views are editable — tablature, standard notation, staff plus tab, and piano roll — and they are the same document: a note entered on the staff appears in the tab, and the other way round. Undo and redo are shared across all four.

Can I play with someone remotely?

Yes. One of you creates a room and shares a six-character code; playback then stays in sync on every device, kept together by a shared clock. The built-in voice chat is tuned for instruments rather than speech — no noise gate cutting off a sustained note. Each player keeps their own view, track and capo.

How accurate is the AI transcription?

It is a starting point, not a finished score. Clean single-instrument recordings give the best results; dense mixes and heavy distortion are harder. What you get is an editable tab to refine — the AI writes down what was played, it never composes anything of its own.

Which formats can I import and export?

Import MIDI, MusicXML, Guitar Pro (.gp, .gp3, .gp4, .gp5) and AlphaTex, plus audio files through transcription. Export to .cesure and PDF for free (the free PDF carries a small watermark); MIDI, MusicXML, AlphaTex and WAV export, and the watermark-free PDF, are part of Cesure Pro.
