Ky

See what your music shares.

Drop MIDI files. Ky compares their notes with the catalogue of open MIDI transcriptions — or with each other — and tells you, plainly, whether anything looks shared, where, and how much. No account needed to run a check.

Three steps. Same answer every time.

  1. Drop

    Up to 40 MIDI files at a time, from any DAW, notation app or AI music tool. No account needed to run a check.

  2. Compare

    Against the catalogue of open MIDI transcriptions, or every file against every other in your batch — aligned by a fixed, deterministic method (the same file gives the same result), not a model's opinion.

  3. Read

    A result in plain words, the bars that matched, how common that material is, and what to look at next: Clear, Worth a look, Likely shared material — or Looks like a version.

Check from where you make music.

One button in your tool: it sends the MIDI to Ky and opens the result. If you've never signed in, it asks you to — then remembers.
