Supermemory vs Zep: Which Memory Solution Wins in April 2026?
Blog post from Supermemory
Written by Supermemory’s founder and explicitly framed as a biased comparison, the piece contrasts Supermemory with Zep as AI-agent memory and context platforms. It describes Zep’s Graphiti engine as a three-layer, bitemporal knowledge graph suited to tracing when information was recorded or changed, making it potentially valuable for compliance and audit-focused conversational applications, while arguing that broader document ingestion, multimodal extraction, connectors, and profile management require additional custom infrastructure. Supermemory is presented as an integrated API combining memory graphs, RAG retrieval, user profiles, connectors for services such as Notion and Slack, and extractors for documents and media; the author claims sub-300ms retrieval, 85.4% LongMemEval accuracy, and leading LoCoMo and ConvoMem results. The comparison emphasizes Supermemory’s claimed lower implementation and maintenance burden through bundled capabilities and token-based pricing, while acknowledging Zep as a reasonable choice for teams whose primary need is bitemporal auditing and that already operate separate ingestion pipelines.
