| What makes it different | - User-owned context that travels with you across AI products
- Traceable agent activity with full visibility and control
- Agents coordinate through shared context without learning being trapped in silos
- End-to-end encryption with no data selling
| - Reaches answers across unrelated documents that share no keywords, where vector search scores zero
- Deterministic retrieval with no model in the path, so results never vary between queries
- Constant per-query cost regardless of memory size, even at 32,000 words
- No infrastructure to run—no vector database, cluster, or GPU needed
- Works with any model, so small local models gain the most from better retrieval
