Key features
  • Sub-200ms context retrieval at scale
  • Temporal context graphs with point-in-time queries
  • Entity-graph spreading activation for cross-vocabulary retrieval
  • Works with any LLM model
  • No LLM or GPU in retrieval path
  • Point-in-time and windowed recall
  • Timestamped memories

What makes it different
  • Reduces token use by up to 90% compared to traditional retrieval
  • Temporal context graphs that track how business information changes over time
  • Enterprise-scale Context Lake supporting millions of graphs
  • 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
