“AFFiNE is an open-source productivity app with a workspace that blends structured note-taking with visual thinking. It’s a bit like Notion, Obsidian, Miro, and NotebookLM combined, but in a minimalist package. There are paid tiers that give you access to more of its AI features and cloud storage (it is a local-first app, though). But you don’t need to subscribe for the everyday management features.”

There is a good write-up about this product in the linked article below. I’ve always preferred flat markdown files as I can see them and access them with any markdown editor, but I did install AFFiNE a while ago on my Linux desktop. I really liked what it can do in terms of creativity and ideas collaboration.

I don’t think, though, that it will replace my notes app as I like to have my notes on hand where ever I am. With AFFiNE you do need to use its app for the creation and viewing. That said it does install on macOS, iOS, Android, Windows, Linux, and can work through a web browser too.

Looking again at that list, and the fact that you can self-host it, I may have to give this another try as it seems with all that, I probably can sync everything across all my devices. For example, in my desktop AFFiNE app there is an option to sync it with the AFFiNE cloud, which includes a link to your own self-hosted instance. It does also support Markdown formatting, as well as export to/import from markdown files. I tested the import of a Markdown document I’d done a while ago in Obsidian Notes, and it imported perfectly, complete with to-do lists, code blocks, tables, etc. The mobile app though does not appear to export/import Markdown documents itself.

Plain documents can be created and edited in AFFiNE’s Page mode, but you can also switch to the Edgeless Canvas mode where all the whiteboarding, graphics, etc magic happens.

Currently, I’m using Joplin for all my markdown notes, and syncing to a self-hosted Joplin server app. Although Joplin is doing everything I want with markdown notes, it does not store the notes in plain markdown files (like Obsidian Notes does). So, in truth, as fat as file formats go AFFiNE won’t be much different from Joplin Notes, and if the browser access can actually view and edit notes directly on the self-hosted AFFiNE instance, that would actually be a big plus over Joplin Notes for me.

I’m going to rethink my Joplin vs AFFiNE decision, I think.
