Open Upload and choose the File tab for a PDF, photo, or Word document, or the Paste text tab to paste a chord sheet directly.

• PDFs are converted to images in your browser — nothing leaves your device until the converted pages upload.
• Choose One song, Multiple songs (songbook), or let the AI decide with Auto.
• Use AI Instructions for hints like “skip page 1 (cover)”, “split by page”, or “the book uses flat keys”.
• Pasted text that looks like a chord sheet is parsed instantly on your device with no AI call; anything else goes through AI extraction.
• Converted pages and pasted-but-unparsable text are sent to ChordLib's AI provider for transcription. Chord sheets that parse locally never leave your device.

Click ✎ Edit on a song to edit the whole sheet as plain text. Write chords inline in square brackets, directly before the syllable where the change happens:

# Amazing Grace
## by John Newton

### Verse 1
[C]Amazing grace, how [F]sweet the sound
[C]That saved a [G]wretch like [C]me

• [Chord] — inline chord, e.g. [Am], [G/B], [F#m7].
• ### Section Name — section heading; add (x2) for repeats.
• # Title and ## Subtitle — title blocks.
• // note — a free-text note.
• Blank line — separates bars from each other.

Press Apply & save when done. Title, artist, original/current key, categories, and notes are edited in the details panel beside the song and save automatically. Capo and BPM come from the original import and are shown in perform and print views.

• Transpose: Alt+↑ / Alt+↓ or the − ♭ / + ♯ buttons. Your transpose is remembered per song.
• Font size: - / + or the A− / A+ buttons.
• Autoscroll: press Space to start or stop, Esc to stop. Pick from five speeds (Slower → Faster).
• Fullscreen: the ⛶ Full button; Esc exits.
• Print: the ⎙ Print button in the ⋯ menu prints a clean page with title, key, capo, BPM, and time signature.
• Prev / next: ← / → moves between songs in a setlist's Perform mode.
• Two columns: the ▥ button splits long songs into two columns on wide screens.

A setlist is an ordered group of songs for a single service or performance. Create one from Setlists, add songs, drag them into order, and set a per-song transpose offset (remembered for next time).

Perform mode shows one song at a time with prev/next navigation and each song already transposed by its offset. Print Setlist prints every song stacked with page breaks.

Use the 🔗 Share link button on a song to create a public link anyone can open — no account needed. Links expire automatically after 30 days, and you can revoke a link at any time, after which it stops working immediately.

• Does ChordLib work offline? — Songs you have already opened, plus the first page of your library, are cached on your device and stay readable if the network drops.
• My PDF has many pages. What should I do? — Use Multiple songs (songbook) mode; very long PDFs are capped per upload, so split large songbooks into smaller files.
• The AI put chords in the wrong place. How do I fix it? — Open ✎ Edit and move the [Chord] brackets to the right syllable, then Apply & save.
• Someone I shared with says the link stopped working. — Links expire after 30 days or when revoked. Create a fresh link from the song or setlist.
• How do I get an account? — Accounts are created by the administrator.
