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.
Point it at a folder. It indexes, summarizes, and scans — then gets out of your way.
Index any folder of markdown recursively. Add a GitHub repo and it clones and indexes it for you.
Vector embeddings with cosine similarity. Switch between keyword and meaning-based search instantly.
Automatic abstracts for every file via local Ollama or your choice of Anthropic, OpenAI, DeepSeek, or Google.
14+ rules including Gitleaks patterns flag secrets, credentials, and PII with risk badges right in the tree.
Tag and browse by category — manually or AI-assigned — with a directory tree view and inline risk badges.
A REST API at localhost:7734 so your IDE agents can query the vault programmatically.
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.
The core is free forever. Paid tiers unlock unlimited vaults and commercial rights.
