Knowledge Graphs
Semantic relationships between concepts are mapped automatically, giving your searches contextual depth that keyword matching cannot achieve.
Unfold
Your Knowledge
With AI That Respects Your Privacy
Terraphim AI is a privacy-first assistant that uses knowledge graphs and semantic search to surface precisely what you need -- entirely on your own terms, on your own device.
Features
Precision, Unfolded
Every layer of Terraphim AI is designed to bring clarity to your knowledge, without compromising your privacy.
Semantic Search
Multiple relevance algorithms -- BM25, TitleScorer, and graph-based ranking -- work together to surface the most meaningful results.
Local-First Privacy
All processing happens on your device. Your data never leaves your machine unless you explicitly choose to share it.
Haystack Integrations
Connect to Confluence, Jira, Discourse, email, local files, and more. One search across all your knowledge sources.
Role-Based Configuration
Define roles with tailored knowledge domains, search preferences, and AI settings. Switch contexts with a single action.
MCP Protocol
Model Context Protocol integration enables AI development tools to leverage Terraphim's search and autocomplete capabilities directly.
Process
How It Works
Four steps from installation to insight. Each one unfolds naturally from the last.
1 Install Locally
Download the desktop application or build from source with Cargo. Terraphim runs entirely on your machine -- no cloud account required, no telemetry, no data leaving your device.
2 Connect Your Sources
Configure haystacks to point at your knowledge: local folders, Confluence pages, Jira tickets, Discourse forums, email via JMAP, or any MCP-compatible service. Each source is indexed with concept extraction.
3 Build Knowledge Graphs
Terraphim constructs a thesaurus of related concepts, builds Aho-Corasick automata for efficient matching, and maps semantic relationships across all your connected sources.
4 Search and Discover
Query across everything at once. The graph-based ranking surfaces results with deep contextual relevance, whilst AI-powered summaries and chat help you explore and understand what you find.
Developer Experience
Built for Engineers
A clean API, a powerful CLI, and full Rust source code you can audit and extend.

Privacy First
Your Data, Your Device
Privacy is not a feature we bolt on. It is the foundation everything else is built upon.
Fully Local
All indexing, search, and AI inference can run entirely on your machine.
No Telemetry
Zero tracking, zero analytics, zero phone-home. Audit the source yourself.
You Control Sharing
Optional external integrations are explicit and revocable at any moment.
Open Source
Every line of code is available for inspection, contribution, and self-hosting.
