Thanks!

1. We chose Markdown deliberately so each node is human-readable and editable. The idea is that a project or person note represents the current state of that entity, so you can just open it and understand what’s going on. That also lets users add updates manually, for example from offline conversations that aren’t captured in email or meetings.

In terms of performance, the graph mainly acts as an index over structured notes, and retrieval happens at the note level rather than through complex graph queries. So for our use case, plain files have been sufficient and keep the system simple and transparent.

2. It’s actually Obsidian-compatible. The notes use Obsidian-style backlinks, and you can open the folder directly as an Obsidian vault if you’d like.
