Logseq
Logseq is a knowledge management and collaboration platform. It focuses on privacy, longevity, and user control. It is Free Libre Open Source Software (AGPL-licensed).
Logseq offers a range of powerful tools for knowledge management, collaboration, PDF annotation, and task management with support for multiple file formats, including Markdown and Org-mode, and various features for organizing and structuring your notes.
Logseq's Whiteboard feature lets you organize your knowledge and ideas using a spatial canvas with shapes, drawings, website embeds, and connectors. You can visually group and link your notes and external media (such as videos and images), enabling visual thinkers to compose, remix, annotate, and connect content from their knowledge base and emerging thoughts in a new way.
In addition to its core features, Logseq has a growing ecosystem of plugins and themes that enable a wide range of workflows and customization options. Mobile apps are also available, providing access to most of the features of the desktop application. Whether you're a student, a professional, or anyone who values a clear and organized approach to managing your ideas and notes, Logseq is an excellent choice for anyone looking to improve their productivity and streamline their workflow.

Syncthing is also free as in free beer but it will use your device storage instead of cloud based. Which is also good in terms of privacy but bad in terms of limited storage
@3yiyo3 I looked at Syncthing, but it doesn't support iOS, which is the devices I'm having problems with. (Otherwise I'd use dropbox, which I already have.)
Its a shame that syncthing doesnt support iOS because it is a great app, I didnt know about that. I use it even on MacOS
@3yiyo3 Yeah, iOS makes it difficult to do this kind of thing (on purpose), though https://www.mobiussync.com/ seems to be a solution.
I'm reluctant to rely on a one-person-made app for this, given that Apple really wants you to use iCloud for syncing, which they should just make work better.
