Zep
Fast chat memory with fact extraction and session summaries
ZenBrain9.0 / 10
Zep is a strong chat memory system with fact extraction and session summaries — ideal for chatbot developers who need fast memory. ZenBrain goes significantly deeper: 7 memory layers, neuroscience algorithms like Sleep Consolidation and Hebbian Learning, and a MemoryCoordinator that orchestrates all layers. For projects that go beyond chat memory, ZenBrain is the better choice.
