Built by Arc Labs
We build intelligence infrastructure for people and organizations that refuse to trade privacy for capability.
The Problem
Every intelligence platform asks you to hand over your data. Your thoughts, your relationships, your strategies — all stored on someone else's infrastructure, training someone else's models, subject to someone else's policies.
The more valuable your data, the less control you have. That's backwards.
Our Approach
Privacy by architecture — not by policy, not by promise, but by design. Your data lives on your infrastructure. Your knowledge graph runs locally. Your AI chat never phones home.
We don't have access to your data because the system is built so we can't have access. That's the only kind of privacy guarantee that matters.
The ARX Protocol
An open standard for personal knowledge graphs. The foundation everything else is built on.
Knowledge Graph
Every thought, decision, and pattern captured as nodes in a graph. Edges connect related ideas. Semantic embeddings find what keyword search misses.
Personal Language
Synap learns how you communicate. AI interactions become more natural over time because the system adapts to your language and context.
Multi-Device Sync
Your knowledge graph syncs across all your devices. Works online or offline with self-contained knowledge bundles.
