About Flat
Flat is an online music notation editor for writing and reading sheet music. This plugin lets users work with the scores in their own Flat account from ChatGPT. They can turn notation ChatGPT writes or converts (MusicXML, MIDI, ABC, MuseScore, Guitar Pro) into a new score and open it in Flat's editor, search their scores and collections by title, composer or instrumentation, read a score's details (title, composer, instruments, duration, measures), and export a score's notation as MusicXML or MIDI for analysis, arrangement or transposition. New scores are created private or link-only; publishing stays a decision the user makes in Flat.
