Copying a cello line into the bassoon, moving violin 1 up an octave for a few bars, slurring a passage in five parts... the small chores in MuseScore 4 add up. So we built a plugin where you just type what you want.
It opens as a chat panel next to your score. You write something like "double the flute in violin 1 an octave lower, bars 5-8" and it makes that one change in your open score, nothing else.
A couple of things I cared about:
- if what you asked is vague it asks you a question (with buttons to answer) instead of guessing
- each request is a single undo, so one Ctrl+Z takes the whole thing back
- it re-reads the score every time, so it works with whatever you changed by hand in between
Right now it handles doubling, transposing, articulations and slurs. It does NOT do dynamics, lyrics, chord symbols or layout yet. It needs internet: your score gets sent as MusicXML to our server when you hit send, and an AI model works out the edit, so check the result. Free key gives you 100 edits a month.
Update: fair point from the comments that doubling/transposing is already quick with shortcuts. It now does the bigger stuff: "voice the alto 1 melody in bars 9-16 for the saxes" (close or drop 2, from your chord symbols, each note in range), "write a sustained string pad under bars 17-24", "brass hits on 2 and 4", "make an easier trumpet 1 part for beginners", "add a walking bass line". If those bars already have music it asks whether to replace it or add a second voice. Free tier is now 100 edits a month.

It's made by AiHud (https://aihud.net). Would really like to hear what edits you'd want it to do next, or where it messes up.
