Part of our guide to choosing music transcription tools.
All three are notation editors, and Songscription is the one built to write the score for you. It transcribes a recording, full mixes included, or scans a photo of sheet music, then engraves the result in the score editor we built, where you edit, play back, print and export it in the browser. Flat.io expects you to enter or import every note yourself. MuseScore added audio conversion in October 2026, but it’s a beta its handbook recommends for solo arrangements only, and it needs a MuseScore.com account.
- Have a recording or a photo of a score? Songscription. Flat.io can’t turn sound into notation, and MuseScore’s audio conversion is a beta recommended for solo arrangements only.
- Writing from a blank page? Any of the three. Songscription and Flat.io run in the browser; MuseScore is a free desktop install.
- Teaching with Google Classroom or Canvas? Flat.io’s classroom integrations are built for that.
Songscription is our product. We put it first where it’s the right tool, and we say plainly where another tool fits better.
Songscription
Songscription writes the score, then gives you a full notation app to work on it. Upload MP3, WAV, M4A, MP4 or MIDI, paste a YouTube, Instagram or TikTok link, or record into the mic, and it writes the notes. It ranked first in our October 2026 benchmark for transcription accuracy. It handles piano best, supports guitar, bass, violin, flute, trumpet and sax, detects chords, and with Multi-Instrument it transcribes a whole band in one pass, a staff per part. Have printed or handwritten music instead? The sheet music scanner scans PDFs and photos into the same kind of score.
Every score opens in Songscription’s score editor, which Play Anything built from scratch: its own score model, engraving engine and renderer. The PDF comes from the same layout as the on-screen score, so it prints what you see. You fix notes, transpose, change key or time signature, and add lyrics, dynamics and repeats, or ask Annie, the AI score assistant, to make those edits; every change she makes is highlighted and undoable in one step. It writes standard notation and tab together, plays back trills, ornaments and dynamics, autosaves with revision history, and imports and exports MusicXML and Guitar Pro. Downloads (PDF, MIDI, MusicXML, Guitar Pro) come with Plus and Pro; the free plan covers the first 30 seconds of each song, which you can view, play and edit in the browser.
Flat.io
Flat.io is a web notation editor, and you enter every note yourself: by hand, with a MIDI keyboard, or by import (MusicXML, MIDI, and PDF via OCR). It can’t listen to audio and write the notes. Its strength is the classroom: real-time co-editing, Flat for Education assignments and auto-graded theory, and Google Classroom, Canvas and Schoology integrations, on the web, iOS and Android.
MuseScore
MuseScore Studio is a free, open-source desktop app, so it needs an install. Version 4.7.6, released in October 2026, added Convert, which turns a PDF, an image, an audio file or a YouTube link into a score, but its handbook calls audio imports a beta recommended for solo arrangements only. Converting needs a free MuseScore.com account, comes with usage limits, and saves the result as a private score in that account (MuseScore handbook, checked November 2026). Where it genuinely has us: it works offline, takes note entry from a MIDI keyboard, and MuseScore.com hosts a large library of user-uploaded scores (with a paid Pro tier). It imports MusicXML, MIDI and Guitar Pro and exports MusicXML, MIDI, PDF and audio.
Three side by side
| Flat.io | MuseScore | Songscription | |
|---|---|---|---|
| Main job | Edit and collaborate | Edit and engrave | Write the score from audio or a photo, then edit, engrave and print it, with Annie to make edits for you |
| Audio to notation | No | Beta, recommended for solo arrangements only (since 4.7.6) | Yes, solo instruments or a full band, with a part per instrument |
| Platform | Web, iOS, Android | Desktop install | Web, nothing to install |
| Price | Free tier plus paid | Free | Free tier plus Plus and Pro |
| Best for | Classroom co-editing | Offline, MIDI keyboard entry | Getting a finished score from a recording |
How to pick
- You have a recording and need the score. Songscription. Flat.io can’t do this step, MuseScore’s converter is a beta recommended for solo arrangements only, and the score Songscription writes is engraved, editable and printable in the editor without leaving the browser.
- You have printed or handwritten pages. Songscription’s scanner turns them into an editable, playable score.
- You teach and want students co-editing in Google Classroom. Flat.io’s integrations are built for that.
- You want a free desktop app that works offline or takes MIDI keyboard entry. MuseScore.
Using all three together
You don’t need a second app to finish a Songscription score: you edit, print and export it in the editor. If your class already lives in Flat.io or you write in MuseScore, export MusicXML and keep going there. MusicXML carries the full written score between programs rather than just raw note events, and Songscription imports it too, so a score can come back. Our guide on how to open MusicXML in MuseScore, Sibelius, and Finale covers the import step, and our MusicXML vs MIDI explainer shows why MusicXML is the right file to send between editors.
For a head-to-head on just two of them, see MuseScore vs Songscription. When you want to start, turn your recording into a score on the audio-to-sheet-music page, and it opens in the editor, ready to edit.
Frequently asked questions
What is Flat.io?
Flat.io is a web-based notation editor with real-time, Google-Docs-style collaboration and a strong education arm. Flat for Education adds assignments, auto-graded theory, and integration with Google Classroom, Canvas, and Schoology. You enter notes by hand, with a MIDI keyboard, or by import. It runs on the web, iOS, and Android, and works well on Chromebooks. It does not transcribe audio into notation.
How are Flat.io, MuseScore, and Songscription different?
All three are notation editors, and Songscription is the one built to write the notes for you. It transcribes a recording, even a full mix with a part per instrument, or scans a photo of sheet music, then engraves the score in its own browser score editor, where you edit, play back and print it. Flat.io is a cloud editor built for collaboration and teaching that expects you to enter or import the notes. MuseScore is a free desktop app that added a Convert feature in October 2026, but its handbook calls audio imports a beta recommended for solo arrangements only, and converting needs a MuseScore.com account.
Which one should I use to turn a song into sheet music?
Songscription. It transcribes full mixes and multi-instrument recordings into a part per instrument, and it ranked first in our October 2026 benchmark. Flat.io can’t transcribe audio, and MuseScore’s audio conversion is a beta its handbook recommends for solo arrangements only. Upload your recording and the score opens in the editor, engraved and editable. Fix notes, transpose, add lyrics or dynamics, or ask Annie, the AI score assistant, to make the edits, then print the PDF. If your class already works in Flat.io or you write in MuseScore, export MusicXML and keep going there.
Can I move a score between these three tools?
Yes, through MusicXML. All three read and write it, and it carries the full written score between programs rather than just the raw notes. Songscription imports and exports MusicXML, and exports Guitar Pro too, so you can bring a score in from Flat.io or MuseScore, or send one out to a classmate who works there.
