Connect in ChatGPT
Today ScanSing connects through ChatGPT's developer mode, on the plans that have it (Pro, Business, Enterprise and Edu).
- In ChatGPT open Settings → Apps → Advanced settings and turn on Developer mode.
- In Settings → Apps choose Create app. Name it ScanSing, enter the MCP server URL
https://mcp.scansing.app/mcpand choose OAuth. - The ScanSing sign-in page opens. Enter your email and open the link we send. A new email gets an account with 20 free pages a month.
- In a new chat, pick ScanSing from the + menu and give it a link to a score.
Menu names in ChatGPT change from time to time; if one is not where we say, look for Apps or Connectors in Settings.
What you can ask
- Transcribe this score to MusicXML: https://scansing.app/assets/scores/hosanna.pdf
- What key and time signature is it in, and what is the alto's range?
- Give me just the tenor part, a tone lower.
- Make a MIDI of the soprano line so I can practise.
How accurate it is
On eight clean engraved scores ScanSing read 99.0% of notes right, against 96.7% for PlayScore 2 and 71.8% for Audiveris. The comparison has every score, the method and where ScanSing loses.
Pages and limits
PDF, PNG, JPEG, HEIC (iPhone photos), TIFF and WebP, up to 30 MB and 40 pages. Printed, engraved music reads best; handwritten scores are not supported. A page takes about 10 seconds, a long PDF a few minutes. Only recognising spends pages; describing, extracting a part, transposing and MIDI work on the stored result and are free. Free: 20 pages a month for a new email; Starter $9 for 300 pages a month; Pro $29 for 1,500. Details on the connector page.
Questions
Which ChatGPT plans can connect it?
Developer mode, which adds custom apps, is on ChatGPT Pro, Business, Enterprise and Edu. On other plans, use ScanSing from Claude or through the REST API.
Is ScanSing in the ChatGPT app directory?
Not yet. Until it is, connect it in developer mode as described above.
What does it cost?
A new email gets 20 pages a month, without a card. Only recognising spends pages; parts, transposition and MIDI of a recognised score are free.
What does ScanSing see?
Only what a tool is given: the score or its address, and the options. It does not see your conversation, and scores are not used to train models.
How do I disconnect?
Remove the app in ChatGPT's Settings → Apps, or on your account page, where every connected app is listed.
