Show HN: A memory database that forgets, consolidates, and detects contradiction

Article

• Purpose-built vector DB for AI agent memory with forgetting, consolidation, and contradiction detection
• Built after ChromaDB recall quality degraded badly at ~5k memories
• Uses half-life decay and LLM-assisted merging to prune stale/redundant facts

Discussion

• Author confirms ChromaDB degradation was the direct motivation; recall became garbage at scale
• Skepticism: contradiction detection without context is very hard — most facts aren’t cleanly atomic
• Compared to mem0; one commenter stopped using mem0 because “facts” are too rigid for real tasks
• Interest in consolidation loop details: random sampling + LLM to merge?
