CoLabRoom Beta

Write the song.
Find out what you played.

Songwriting apps make you fight the app. This one gets out of the way — one page for the words, a colour for whoever wrote them — and then tells you the key, the tempo and the chords of the take you just played.

[ Intro ]

The app should be the easy part.

Nobody picked up a guitar hoping to learn software. CoLabRoom is built so the song is the only thing you have to think about — and so that when you finish a take, you know more about it than when you started.

Nothing to set up

Make a Room, make a song, start typing. No templates, no fields, no configuration.

Nothing to file

It saves as you write, and names your recordings after what you sang in them.

Something to show for it

One take gives you the key, the tempo, the chords and the shape of the song.

Nothing hiding in a menu

Analyze, Record and Live are the verbs you opened the song for. All three sit on the screen, not three taps into an overflow menu.

[ Verse ] — Writing

A page, not a form.

Other apps make you file the song before you can write it: a box for the title, a box per line, a button to add a section. CoLabRoom gives you one flowing page. Type, paste, delete a verse, move on.

Everyone has a colour

A coloured dot beside every line shows who wrote it — attribution without a comment thread.

Voice notes on the line itself

Hum the melody where the words are. Tap the dot, sing the part, and it lives on that line.

It saves while you write

No save button. Edits reach the room as they happen, and the page says so plainly if one doesn't.

Headers it recognises

Type [Chorus] and it looks like one. No formatting menu.

[ Chorus ] — Analysis

Play it once. Find out what you played.

Record a take, or upload a demo you already have. You get back the things you would otherwise work out by ear at two in the morning.

  • KeyThe key it is actually in, not the one you meant to play.
  • TempoBPM, and the beat positions everything else aligns to.
  • ChordsA beat-aligned chord map, with how much of the song it is sure about.
  • StructureWhere the verses, choruses and instrumentals fall — renameable to whatever the band calls them.
  • InstrumentsWhat it heard playing.
  • LyricsA transcript timed to the audio, word by word.
  • StemsThe take split into parts, so you can play along with the drums and leave your own guitar out.

  • Analyzing chords & structure
  • Saving your song map

Every chord is a suggestion, not a verdict. Tap one that is wrong and fix it — your correction is what sticks, and the original stays in history.

[ Verse ] — The Studio

You can't skim audio.

That is the reason every musician has eighty voice memos called Recording 8/23 11:40 and revisits none of them. A take you can't identify without playing it is a take you never play.

So the Studio names an idea after the first thing you actually sing in it, and only ever replaces a placeholder — never a title you typed yourself.

Then it makes them searchable by their words. Half a remembered line is enough to find the recording, and the result tells you which line matched.

Streetlights on the way home Name

Something I hummed in the car Lyric

…all the way down, streetlights counting off the miles…

0:48 · G major · 112 BPM

Both of these were named by the app. Neither was typed.

Drop a memo in with no project, no title and no commitment. If it turns out to be something, it becomes a real song project in one tap — recording and analysis already attached.

[ Bridge ] — Song Sheet

Chords where the chords go.

Above the words, at the syllable they land on. Move one, add one, delete one. Rotate the phone for a two-column sheet you can read from a music stand, then print it or send the band a PDF.

[ Chorus ] — Live

For the part where you actually play it.

Live mode scrolls the song so your hands stay on the instrument. With an analysed recording it follows the real per-line timing — waiting through the intro, holding through the instrumental — instead of creeping down the page at a constant speed.

Or just set a speed

No recording yet? Slow, medium, fast, or spread across the song's length. It works before the song is finished.

Count-in and Tap Sync

A count-in before it moves, and one tap to put it back where you are when the band takes the long way round.

[ Verse ] — Import

Bring the songs you already have.

Your back catalogue is in a notes app, three PDFs and a spreadsheet. CoLabRoom reads PDF, Word, RTF, Excel, CSV, OpenDocument, Markdown, plain text, a public Google Sheet link, or anything you paste — and shows you the lyric lines, section labels and chords it found before a single one lands.

[ Verse ] — The band

Rooms, not group chats.

A Room holds a band's songs and stays visible only to its members. Each song keeps its own stream of what changed and who said what, so nobody scrolls a group chat to find out what happened to the bridge.

Setlists

Build a set from songs across Rooms, reorder it, and print or share the whole thing at once.

A Toolbox that stays put

Open chord shapes, capo chart and scale formulas for guitar; tuning, scale formulas and root-note patterns for bass. Offline.

[ Outro ] — The beta

It is a beta, and it is honest about it.

CoLabRoom is in testing on Android now, with iOS next — one codebase targets both. The automatic chord and lyric analysis is a draft assistant, not an oracle: manual chord correction and Tap Sync are the finishing tools, and they are meant to be used.

There is a feedback option inside every song. It goes straight to the person building this, with the screen you were on and the version you are running attached.

Your account and your songs

Rooms are private to their members. Voice notes and reference recordings are stored with the Room they belong to. Imported documents are read on your own device.

To delete your account:

  1. Open CoLabRoom and go to the Account tab.
  2. Choose Delete account and confirm.

This is immediate and permanent. It removes your account and the songs, lyric lines, edits, comments, uploaded files, recordings and invitations attached to it. There is no undo and no recovery window.

If you cannot sign in and need your account removed, email support@colabroom.com from the address you signed up with.
