What they did
Autograph is a music notation editor for iPad and Mac with its own engraving engine, playback and PDF export, and it supports MCP so Claude can write notation in it.
Result (as claimed)
You can handwrite with Apple Pencil or have Claude draft the score.
Tools they used
Cost: Pricing depends on the tools you pick; check each official pricing page.
Set it up
Collect your inputs
List what goes in (raw footage, script, topic list or audio) and the exact output you want, for example 5 vertical clips under 45 seconds. Put inputs in one folder.
Set up the tools
Open Autograph, Claude Code, Claude Desktop, MCP. Connect accounts only where needed and note any per-minute or per-credit limits on the free plan before you start.
Run one piece end to end
Make a single output first. Check pacing, captions, voice and framing by watching it on a phone.
Turn it into a repeatable recipe
Save the prompts and settings that worked as a template so the next run takes minutes, then batch.
Review before you post
Watch every output before publishing. Check rights for music, likeness and footage, and label AI content where the platform requires it.
Copy the full setup prompt
Paste into your agent and it will walk you through the setup, asking before anything that sends, posts or spends.
