Start a session with a memorable code, share it with the room, and every device sees the same chart synced to the leader. Pick a song and the band follows. When you scroll, they scroll with you. No accounts required for viewers — perfect for jams with friends or pickup gigs with strangers.

Build a private library of chord charts you can pull up at a moment's notice. Paste a chart and we'll suggest the title and artist, warn if you already have a similar song, and detect the key automatically. Tap the + button in your library to create a new chart.

Upload a PDF, DOCX, or TXT songbook and Choordinator splits it into individual charts. Chord alignment is preserved — the importer reads the source PDF's text positions directly, so chord-over-syllable spacing comes through clean.

Drag songs into the order you want to play them. Setlists show estimated total duration so you can plan your slot. Start a session straight from a setlist and the whole queue is loaded for you.

Bands get their own shared library, setlists, tags, and annotations. Owners and editors can curate the catalog; members can read and rehearse. Invite codes get anyone in instantly.

Notes are a band feature — scoped to how you play a song with a specific group. Editors can write team notes visible to everyone in the band (e.g. “Capo 3, skip second verse”), and every member can add their own private note for personal reminders. Notes for the same song in different bands stay separate, so your cues always match the arrangement. Scroll speed and start delay are saved alongside the chart.

In a band chart, switch the editor into Highlight mode and tap any section header or inline hint to color it. Eight colors let you cue different instruments, mark dynamic changes, or call out the bridge — and everyone in the session sees it.

Use familiar markdown-style markers in your chart and Choordinator renders them styled while keeping chord-over-lyric alignment perfect. Great for emphasis, whisper-soft sections, or call-and-response cues. Type these markers directly into any chart in your library or a band workspace.

Don't recognize that chord? Tap it. A guitar fingering pops up right next to the chord, with around 150 voicings built in. No leaving the chart, no breaking flow.

Adjust font size, switch into compact mode, or pinch to zoom for the perfect reading size. Day and night themes for any lighting condition.

Pair a Bluetooth page-turner pedal and set it to arrow key mode (ArrowUp / ArrowDown). Choordinator captures arrow keys on all platforms including iPad — no fullscreen needed. A forward press starts auto-scroll or nudges the chart down; backward nudges up or stops scrolling. Both leaders and viewers can use pedals.

A chromatic tuner that uses your device microphone, and a metronome with tap tempo and adjustable BPM. Both live on the Tools page, one tap from anywhere.

Every session is logged, every played song counted. Browse your history to see what you played last week, or check play counts in your library to surface your most-used charts.

Your personal library is private to you. Songs only become visible to other people when you add them to a band workspace you belong to — that's the way Choordinator is meant to be used with a group. Choordinator is a tool for playing together, not for publishing or distributing chord charts.

Deleted charts move to your Trash, where you can recover them at any time. Nothing is gone for good until you say so. Visit your Library and tap Trash to see deleted charts and restore them.
