Chords365 song view with chords, setlist navigation and drawn annotations

An empty chord book you fill yourself — the way that works for you.

Chords365 isn't a ready-made song catalog — it's a digital chord book: you decide what goes in and where it comes from. Type a song in, import it from ChordPro or ZIP, photograph the paper chart, or pull it in from several public song libraries — then add audio recordings and stem sets (even from YouTube) to make learning easier for singers and players alike. Its biggest strength: the whole team's life comes together in one place — shared setlists, events, media library and broadcast messages. Built by one musician, for musicians — straight from the heart.

Your own sources Type it in, import from ChordPro or ZIP, scan a photographed chart, or pull from several public song libraries.
Chords and sheet music in one ChordPro with automatic transposing and classic sheet images — for one song, side by side.
Audio for learning Audio recordings and stem sets, separated even from YouTube, for easier practice.
The whole team Shared setlist, events, media library and broadcast messages — all in one place for singers and players.

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.

Songs and chords

ChordPro foundation, flexible notation

You can edit songs as clean ChordPro text or in WYSIWYG mode, while the source stays compatible in the background. The biggest win: transpose any song to any key with a single button — the chords follow automatically — and the interface shows H or B chord names per user.

  • H/B toggle that persists across devices.
  • Automatic transposing with one button, original key, capo-fix and per-setlist saved key.
  • Search, favorites, ZIP import/export and lyrics download.
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

Chords and classic sheet music — side by side

You don't have to choose: alongside the chord view, any number of classic five-line sheet images can belong to the same song — in several parallel sets you switch between with a single touch. The sheet music fits the screen width, and you can draw on any page; personal and group annotations are handled separately.

  • A song can have several sheet image sets — switch between them with the version pills.
  • Pencil, eraser, colors, line thickness, finger and stylus drawing on any page.
  • Works offline too, 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.
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 — with a background, logo and formatted text — and a remote projector can be paired with a QR code. In a simpler, campfire-style setting, projection mode can even replace dedicated projection software: a phone or laptop is enough. The group administrator keeps the team in order with invitations, events and broadcast messages.

  • Slideshow with background, logo, text formatting and fullscreen mode.
  • At a campfire or a small gathering, projection mode replaces dedicated projection software.
  • Event list, mini calendar, attendance marking, broadcast messages and admin notes.
Search the internet — many sources beta

One search, many public song sources — with merged results

A single search box queries many public song libraries at once — Hungarian and international, with chords, sheet music or lyrics only. When the same song appears in several places it shows as one merged row with source tags; on import you choose which source and form to bring in.

  • One search across many public sources: chords, sheet music and lyrics-only, Hungarian and international.
  • Same song from several sources → one merged row with source tags and content badges (Chords / Sheet / Lyrics only).
  • "Choose a version": on import you decide which source and form (chords, sheet or lyrics) to bring in.
  • chords365.com stores and copies nothing — the download happens on your click, and you are responsible for usage rights.
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.

No flashy extras

Chords365's greatest strength is pulling everything into one workflow — from the song through the sheet image, the audio, the setlist, projection and group life: import, search, practice, multitrack, sync and offline.

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.

Users are responsible for only uploading and using content they have the rights to. Chords365 is not a public song catalogue and does not distribute copyrighted music.

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 app is in an early launch phase and is sustained by voluntary donations; if it's useful, support it here. In the longer term the core features stay free, and a few advanced extras may go into an optional paid bundle.

No. We do not sell your data or pass it on to third parties — the app does not live on advertising or data sales, but on voluntary donations, and it is currently in an early launch phase. Your uploaded songs and your account data remain yours. Details: Privacy policy.

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

You fill the library with content yourself — there is no pre-loaded song bank that everyone sees, and by default only your own songs (and those shared with you by your group) appear. You add the songs yourself: you can type or paste them in, import from a file (for example ChordPro, PDF or image), and with the built-in search you can also browse and bring in songs from the internet, from several sources. This way you can build up your own, lawfully used repertoire in just a few minutes.

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.

Users are responsible for only uploading and using content they have the rights to. Chords365 is not a public song catalogue and does not distribute copyrighted music — it only provides the tools to manage your own, lawfully used songs within your group. Content brought in from other sources does not become the property of Chords365, and no public copy is made of it.

The main safeguard is the design itself: Chords365 is a closed, private tool, not a publishing platform. Anything you upload is yours by default and can only be shared with a group you choose (for example your band or team) — there is no “everyone can see this” switch, no public posting and no public link that anyone could open. You cannot browse or search other users’ content, and nothing goes into a public catalogue or search engines, so copyrighted material cannot spread to the public here. Uploaded content stays with the person who uploaded it, and under the terms everyone may upload only what they have the rights to. If a rights holder still notices an infringement, they can report it at [email protected] and we will remove the content concerned.

Try it at your next rehearsal

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