Replace Raw Vector Memory With Structured, Versioned AI Memory
Vector databases retrieve chunks that look similar. They don't know that yesterday's fact contradicts today's. MemoryLake is a vector memory alternative built for RAG and agent apps that need structured user state, conflict resolution, and audit trails — not just nearest-neighbor matches.

The problem: raw vector search isn't enough for production RAG
A pure vector RAG pipeline returns chunks ranked by cosine similarity. It cannot tell which chunk is authoritative, which is outdated, or which the user explicitly retracted last week. It blurs facts, events, and opinions into a single bag. Production teams patch this with re-rankers, metadata filters, and dedupe logic — eventually reinventing a memory system.
How MemoryLake replaces and extends vector memory
Typed memory, not flat chunks — Background, Fact, Event, Conversation, Reflection, and Skill memory each retrieve differently. Facts dedupe and conflict-check; events stay ordered in time; conversations compress.
Conflict resolution at write time — When new content contradicts stored memory, MemoryLake flags it instead of silently embedding both. You choose the resolution: latest source, confidence weight, or manual.
Versioned memory with rollback — Did last week's ingest poison your retrieval? Roll back the bad commit. Vector stores can't do this.
Pair with your existing vector DB — Keep your document chunks where they are. Use MemoryLake on top for user state, agent state, and structured facts.

How it works as a vector memory alternative
- Connect — Point your ingest pipeline at MemoryLake instead of (or alongside) your vector DB.
- Structure — MemoryLake classifies each chunk into a memory type, dedupes against prior content, and stores provenance.
- Reuse — Retrieve at inference. Get back ranked, conflict-free, type-aware memory ready to drop into the prompt.
Before vs. after: RAG memory stack
| Without MemoryLake | With MemoryLake | |
|---|---|---|
| Conflicting chunks in retrieval | Both returned, model confused | Conflict resolved at write time |
| Outdated facts after a refresh | Stale chunks still surface | Versioned memory rolls forward |
| User-specific state | Stored in a separate session DB | Unified with document memory |
| Audit "where did this fact come from?" | Vector ID only | Full provenance chain |
Who this is for
Teams running production RAG who have outgrown a single vector database — and are tired of writing custom dedupe, re-ranking, and metadata-filtering code to compensate for what vectors don't do.

Frequently asked questions
Do I need to drop my vector database?
Do I need to drop my vector database?
No. MemoryLake complements it. Keep your vector DB for document chunk retrieval; use MemoryLake for user state, agent state, and structured facts.
Does MemoryLake do semantic search?
Does MemoryLake do semantic search?
Yes, on top of structured memory. You get both embedding-based retrieval and typed memory queries from one API.
How does it handle 100M+ items?
How does it handle 100M+ items?
MemoryLake has been benchmarked on 100M+ document workloads with millisecond retrieval latency and 94.03% accuracy on the LoCoMo long-horizon recall benchmark.
