Your markdown, finally searchable.

MDownManager turns any folder of .md files into a structured knowledge base — with semantic search, AI summaries, and a built-in security scanner. Everything stays on your machine.

// AI SUMMARY · local model Defines the service boundaries between the ingest worker and the query API, and why SQLite WAL was chosen over Postgres for the local store.
# System architecture
The vault indexer walks files recursively and writes
embeddings to a local store. Search runs over
`cosine similarity` — no request ever leaves the host.
What it does

A knowledge layer that respects your files.

Point it at a folder. It indexes, summarizes, and scans — then gets out of your way.

🗂️

Vault indexing

Index any folder of markdown recursively. Add a GitHub repo and it clones and indexes it for you.

🔎

Semantic search

Vector embeddings with cosine similarity. Switch between keyword and meaning-based search instantly.

AI summaries

Automatic abstracts for every file via local Ollama or your choice of Anthropic, OpenAI, DeepSeek, or Google.

🛡️

Security scanner

14+ rules including Gitleaks patterns flag secrets, credentials, and PII with risk badges right in the tree.

🏷️

Categories & explorer

Tag and browse by category — manually or AI-assigned — with a directory tree view and inline risk badges.

Local HTTP API

A REST API at localhost:7734 so your IDE agents can query the vault programmatically.

Local-first, by design.

No account. No upload. No telemetry. The Rust core indexes and searches entirely on your machine, and you decide whether AI runs locally through Ollama or through a cloud model you bring yourself.

Files never leave the host unless you opt into a cloud model
SQLite (WAL) store you can inspect and back up yourself
