bigggbob··on Show HN: OpenKnowledge – open source AI-first alternative to Obsidian/Notion
Good point. But doesn’t Obsidian also support a CLI? In theory, wouldn’t that also work well with agents? I’m still curious what pain points this project solves compared with Obsidian or Notion.
bigggbob··on Show HN: Bible as RAG Database
Nice project. The 4GB index / ~15s search part made me think zvec might be a good fit here: https://github.com/alibaba/zvec

It’s an in-process vector DB, so the “local corpus, no separate server” shape is pretty much what it’s designed for. Its benchmark numbers are quite strong, and recent versions also support full-text + hybrid retrieval and DiskANN.

This would be an interesting case to try with zvec: same corpus, same embedding model, then compare indexing time, index size, memory usage, and query latency on normal hardware.
