The honest brief
Graphlit
Graph-native context layer that links ingested content into an entity graph plus stateful memory, not just vector chunks.
- One API for ingest, extract, store, retrieve
- Multimodal (docs, audio, video, images)
- Graph-based entity linking + hybrid search
- Event-driven webhooks for reactive agents
- More infra/overhead than plain RAG
- Overkill for simple doc Q&A
- Cloud-only managed service
- Graph/timeline modeling adds complexity
Zep
Stores a temporal knowledge graph (via OSS Graphiti) that versions how facts change over time, not flat snapshots.
- Open-source Graphiti engine (Apache-2.0)
- Managed Zep Cloud option
- Pulls in chat + business data
- Long-term context for agents
- Graph approach has learning curve
- Cloud is credit-based pricing
- Heavier than simple vector memory
- Newer ecosystem
