Hi Product Hunt! We're the team behind Kumiho Memory, launching here in a few hours.
We built Kumiho around a problem we kept running into: an agent might remember what we decided, but lose why we decided it, which alternatives we rejected, or what changed later.
Hi Product Hunt! Kumiho starts from a different premise: AI memory should hold beliefs that evolve, not just facts to retrieve.
When evidence changes, memory should preserve the earlier belief, record why it changed, and connect decisions that may need a second look. That is the foundation of Kumiho’s belief-based cognitive memory system.
• Decision Memory keeps choices with alternatives, rationale, and evidence.
• code_why traces a code change back to the decision behind it.
• Decomposition links facts and relationships so context stays traceable over time.
We formalize this architecture in our arXiv paper, “Graph-Native Cognitive Memory for AI Agents: Formal Belief Revision Semantics for Versioned Memory Architectures.”

What should your AI remember about how a decision changed?
