Nia Vault is a lightweight CLI that lets developers query local markdown and text files with natural language. The tool performs semantic search across multiple synced folders, returning concise answers and file citations in a RAG‑style format. It plugs directly into the existing nia‑sync workflow.

Under the hood, the command sends a POST /search/query request with a local_folders payload and sets search_mode: sources. The Nia API then returns the best matching passages and the originating file paths, letting users trace insights back to their own notes in their personal repository.

Installation is straightforward: with Bun or npm, run `bun install -g nia-vault` or `npm install -g nia-vault`. After configuring nia‑sync and adding folders, the `vault ask` command lets you query, while `vault sync` keeps local data fresh before searches for the latest information and accuracy.

By keeping search logic local and leveraging open‑source AI, Nia Vault reduces reliance on cloud services and speeds up knowledge retrieval for developers. As teams grow their note repositories, tools like this will become essential for maintaining productivity and ensuring quick access to context in today's.
