Musicians don't want another app — they want less uncertainty.

Digital chord apps always have the same pain points: importing material, platform lock-in, offline reliability, another subscription, stepping into the unknown. Chords365 doesn't try to do everything — it gives you a simple tool.

PDFs, images in chat, old versions?Before every rehearsal: who has which version of the chart?
Shared song library and setlistEvery song, order, key and note comes from the same source.
Mixed chord notation in your team?"B" can mean different things depending on which app a song came from.
H/B display per userStorage is compatible; each musician sees what they're used to.
Network drops right when you need it most?On stage or in a live setting, a save or refresh cannot stop the app.
Offline-first operationChanges appear locally right away and sync in the background when connected.
The leader wants a different song mid-set?On longer songs, repeats and transitions it's easy to fall behind.
MD mode and live followingSong changes and commands can be pushed to the team's devices.

Clear on a big screen, brilliant on a tablet

The most important screens aren't separate worlds: the song, the setlist, the notes, the projection and team collaboration all build on each other.

WYSIWYG chord editing with one touch

Setlist and MD mode

The leader directs, the team follows

The setlist is a live shared workspace. The band leader sets the order, marks breaks, switches songs, and can send commands to everyone else's screen.

  • Drag-and-drop ordering, break rows, quick jump to a song.
  • MD following: the leader's song change appears on followers' screens too.
  • Large overlay: Stop, Continue, Return, End.

Offline-first web application

Network drops, but the song goes on

Opened songs, setlists and edits live locally too. The app doesn't discard your work: it records offline and syncs when connected.

  • Once you've opened it, the content is yours.
  • Text and drawings are both stored on your device.
  • Built with the most modern technologies available.

Sheet music image and drawing

Scanned sheet music is no dead end

If you're playing from traditional notation, you can upload it to the song. The image fits the screen width, and drawing separately handles personal and group annotations.

  • PDF sheet images alongside ChordPro view.
  • Pencil, eraser, colors, line thickness, finger and stylus drawing anywhere.
  • Offline operation for uninterrupted note-taking.

Stage control

Readable, scrollable, non-blinding

In live settings, small details matter: dark mode, large text, pedal, screen keep-awake and easy navigation.

  • Bluetooth HID pedal profiles: classic, AirTurn, BT PageFlip and custom mapping.
  • Dark mode, font size, chord and text color settings.
  • Metronome, BPM and beat sound for practice.

Dark mode, large text and quick menu access in one touch

Central menu

Every feature reachable from one menu

The main menu organizes all app features into themed groups: navigation, song and rehearsal, content and import, projection and control, appearance and device, group and admin.

  • Random fast or slow song with one button — for warming up or starting rehearsal.
  • One tap for MD mode, MD following, light/dark and full screen.
  • Manual, feedback, bug report and support directly from the bottom of the menu.

Stem sets and multitrack

Separate tracks, one shared rehearsal

A song can have multiple stem sets: drums, bass, guitar, keys, vocals, click or guide. In the multitrack view all tracks start together and can be mixed individually.

  • Per-track volume, Mute/Solo, waveform and shared seek/playback.
  • Stem set selection, track upload and full mix upload or YouTube source.
  • AI-powered stem separation from a full mix into individual instruments.
  • Separation, key and BPM analysis prepared for practice.

Projection and group life

The app doesn't end at the song page

Lyrics can be projected in a separate slideshow view, and a remote projector can be paired with a QR code. The group administrator uses invitation links and events to keep the team organized.

  • Slideshow with background, logo, text formatting and fullscreen mode.
  • What's in the session setlist is ready for projection too.
  • Event list, mini calendar, attendance marking and admin notes.

Import from the Ez az a nap! library beta

One click from the chart library to your group's collection

You can search and import songs from the public ~500-song library at kotta.ezazanap.hu. The backend converts the source page content into ChordPro; you choose which variant to save in the tab selector panel.

  • Live search through the source site's own search — chords365.com does not store the result content.
  • Hungarian chord conventions (H/B, Esz/Asz, lowercase minor) automatically converted to standard notation.
  • Choose between Hungarian and original lyrics tab; PDF attachment links are preserved too.
  • The source URL and parser warnings are saved with the song — refinable later.

Image/OCR import beta

Photograph the chart, Chords365 recognizes it

You can photograph a paper chord chart or lyrics sheet with your phone, or upload an image. The backend reads it with Tesseract OCR; Hungarian chord conventions are normalized by the same engine as the Ez az a nap! import — just from a different source.

  • Mobile-friendly image input: the button can open the rear camera directly.
  • Client-side Cropper.js for rotation, cropping, contrast adjustment before OCR.
  • Tesseract with Hungarian + English model; the image never leaves our server during processing.
  • The original image is not stored; you can edit the ChordPro draft before saving.

Image editing and ChordPro review in one interface

No flashy extras

Chords365's greatest strength is pulling the everyday details into the same workflow: import, search, permissions, practice, multitrack, projection, sync.

Library

Search, favorites, frequency heatmap, admin upload and full ZIP export.

Editing

ChordPro source view and WYSIWYG bubble panel, so both technical and less technical members can work.

Group

Invitation link, approval-based joining, group admin interface and member-bound permissions.

Practice

BPM, metronome, beat sound, key saving, stem sets and multitrack sessions.

Multitrack

Per-track volume, Mute/Solo, waveform, stem upload, separation, key and tempo analysis.

Openness

ChordPro and ZIP import/export, so your songs don't get locked into a closed format.

Honestly: what is Chords365 NOT?

It's not a licensed song catalog and not a complete team management system. You upload your own songs that you have the right to use, and Chords365 adds what's missing at rehearsal and performance: quick search, shared setlist, chord notation, offline reliability and stage usability.

A one-person labour of love, running since 2022. It started out as chords.hu and has now opened up to the world as chords365.com - but the heart of it hasn't changed: built by one musician, for musicians.

FAQ

Frequently asked questions

Currently yes: no per-user fee, trial or premium plan. The project is sustained by voluntary support; if it's useful, support it here.

Essentially you build your own library. Chords365 provides song management, editing, search, transposing and team use — not a licensed song catalog.

Yes. It's a web PWA, so it runs in modern browsers on iOS, Android, Windows/macOS and tablets. It can be added to your home screen like an app.

The Music Director's song changes and signals can appear on follower devices — when the leader moves to another song, followers' screens switch too. Scrolling within a song is controlled individually.

From ChordPro and similar text formats yes, and you can upload multiple songs in a ZIP. Starting from PDF or images is also possible, but transposing works best after converting to ChordPro.

Yes. Most Bluetooth music pedals act as HID keyboards, which Chords365 handles with profiles or custom mapping.

Try it at your next rehearsal

One group, a few songs, one setlist — that's enough for the first real experience.
