AI agents are getting smarter, but they still forget everything between sessions. We built DeltaMemory because we kept hitting that wall. Not a vector DB, not RAG, a real memory layer that extracts facts, builds a knowledge graph, and actually learns over time. Rust native. #1 on LoCoMo. 2x faster than Mem0 and other alternatives. 97% cheaper at scale.

The PH Community (ph) is a forum and resource hub for PHP developers, providing discussions, tutorials, and insights on PHP programming and web development. Developers can ask questions, share knowledge, and collaborate with fellow PHP enthusiasts on topics such as PHP frameworks, CMS platforms, and database integration. Additionally, PH Community covers PHP events, job opportunities, and community initiatives, fostering a supportive and engaged PHP developer community.

Product Hunt

DeltaMemory is a cognitive memory layer for AI agents built in Rust, designed to solve the problem of agents losing context between sessions. Unlike vector databases or RAG, it extracts structured facts, builds a knowledge graph, and applies biological forgetting curves to simulate real memory. The system exposes three core actions: ingest, recall, and reflect. It claims the #1 spot on LoCoMo benchmarks, 2x faster performance than Mem0, and 97% cost reduction at scale.
