Show HN: Open-source semantic search over your local notes via CLI
Introducing Nia Vault, a CLI that lets you query your local markdown/text files using natural language.

What it does:

Semantic search over local folders and notes Works across multiple synced directories RAG-style answers with citations from your own files

How it works:

Calls `POST /search/query` with `local_folders` Uses `search_mode: sources` to return answers + file references

Example:

vault ask "What are my notes about project planning?"

OSS: https://github.com/chenxin-yan/nia-vault

How does this compare with QMD (https://github.com/tobi/qmd)?

What is the API key used for?
My guess is that Nia Vault uses Nia.

> Nia is an API and MCP layer that gives agents continuously updated context from libraries, research papers, and docs, so they don't hallucinate and you skip manual ingestion.
