> You can apply tags to blocks, which make them a kind of thing (a project, an author, a quote, a thought)
FWIW, needing typed notes is what settled me on Trilium Notes after a foray into a bunch of alternatives, including Notion, Anytype, Obsidian, etc
I realized that efficient note taking and knowledge management generally means (to me) having "dimension lists" (collections of places, people, projects, ...) being referred to in topical notes/journals/events, generally organized as a hierarchy (but not always). Once you come to that realisation (and that your notes system is essentially a glorified RDBMS), you want a system that ensures that "notes of the same type remain as consistent as possible", which Trilium makes easy via Templates and/or Inheritance (attributes can be inherited in the OOP sense, or composed like traits), collections to represent, manage and edit large amounts of notes at once, and emacs-levels of scripting if that's your jam.

silverbullet
An open source personal productivity platform built on Markdown, turbo charged with the scripting power of Lua
It's not exactly like logseq but I really like SilverBullet (https://silverbullet.md/). It's self-hostable and really hackable (plugins, dynamic categorization via embedding custom queries, etc.). Browsers are the first class platform. I really dislike how logseq/Obsidian etc. try to push you towards local fat clients or web clients that only use browser local storage. I _want_ everything stored on a central server so I can just pick up on any device without having to sync.

Project mention: OpenKnowledge – open-source alternative to Obsidian/Notion | news.ycombinator.com | 2026-06-25
- A dual-observer CRDT to keep the ProseMirror and markdown state in-sync.
The CRDT + git also power a collaborative experience that shows what Agents are doing in the markdown, have undo/redo, and version history. The “Share” and cloud-sync functionality are geared for team collaboration. They feel “no-code” but leverage git/GitHub under the hood, which also means data stays fully private.
In that spirit, we made OpenKnowledge open source for anybody who’s curious or who’d like to contribute. Repo: https://github.com/inkeep/open-knowledge.
We’re actively thinking about plugins/extensibility and what’s next. If you have suggestions or feedback, would love to hear it.

tezcat
Tezcat is an Obsidian plugin that uses AI embeddings to index your vaults and integrate search over your thoughts into your workflow.
I made an obsidian extension that does semantic and hybrid (RRF with RTS) search with local models. I have done some knowledge graph and ontology experimentation around this, but nothing that I’d like to include yet.
This is specifically a “remembrance agent”, so it surfaces related atoms to what you’re writing rather than doing anything generative.
Extension: https://github.com/mmargenot/tezcat
Also available in community plugins.
