Been following your journey and I was waiting for the free tier. A free form note taking app is something I've missed and I think muse would perfectly fit this.
Been using it for a couple of hours now. I'm sold with the PDF excerpt feature. Reading books and papers is going to be fun!
Can you elaborate on the data residency aspects? It's mentioned that all data is stored on the iPad. Do I need to have an iCloud storage account eventually as I accumulate more notes?
