I'm beginning to build/host a series of own-use, self-hostable products for personal benefit, starting with an LLM chat for me & my wife, a photo manager, our personal calendar, "whitelisted" youtube app for kids in our home, investment tracking, story/music playlist for our kids, and so on. Plan is to run and maintain our own ecosystem of essential products for our family.
I'm on the same boat, burnt by Evernote and trying to find the good alternative. Sticking with Obsidian for now with some apple notes in-between. But the former has too many features I don't need and later has this vendor lock-in.
If I ever built a note taking app, I'll be using your tag line as a subtitle and a guiding principle :)
"...just a list of notes with some formatting and sync capabilities"
