Three-step workflow

Go from a source file to a usable score in three steps

  1. 01

    Upload a source

    Start with PDF, score image, MusicXML, or permitted audio and video.

  2. 02

    Create and review

    Check pitch, duration, key, and measures instead of treating a candidate as final.

  3. 03

    Edit and export

    Create Jianpu, transpose, practice with playback, or export an open format.

How it works and what it does

One structured score connects every next action

Every capability is paired with a real score excerpt. A source becomes a reviewable candidate, then moves into one Score JSON project after confirmation.

Trust boundaries

Automate reliable steps and keep human judgment explicit

No perfect-recognition promise

Weak scans, dense engraving, and polyphony commonly require correction.

Candidates stay correctable

Notes, duration, key, lyrics, and measures enter structured revisions.

Private files stay private

Projects remain separate from public examples and evidence.

Formats and projects are portable

MusicXML, MIDI, Jianpu text, and Score JSON reduce lock-in.

Credit rules

How credits are counted today

Credits are deducted when an eligible operation is successfully created, at one credit per operation.

$0One complete free project

Use one complete multi-page PDF or score image with all current project-level tools for life, with 25 credits monthly.

1 credit / operationCredit-using operations

OMR, asynchronous rendering, and persisted exports use credits when successfully created. Synchronous transposition or Jianpu preview does not automatically spend a credit.

Monthly resetPlan allowance

Starter includes 50 credits per month; Converter Pro includes 200. Unused allowance does not roll over.

Free, Starter, and Converter Pro use the same current project-level tools; the main difference is score-processing capacity. Checkout proceeds only when the selected Stripe or Paddle plan has its own configured Price ID.

FAQ

Questions before you start

Is recognition 100% accurate?

No. PDF, image, audio, and video sources produce candidates; difficult material requires human review.

Can I transpose or create Jianpu afterward?

Yes. Editing, Jianpu, transposition, playback, and export read the same accepted score project.

Which export formats are supported?

MusicXML is the primary interchange format, with MIDI, Score JSON, Jianpu text, and verified deployment exports.

Is audio-to-score available now?

It opens as an experimental capability with explicit format, quota, and correction boundaries.

Will my uploads become public?

No. Private projects do not automatically become public examples.
