Engineering & Developermemory API for LLM developers

Ship LLM Apps Without Building Memory Infrastructure From Scratch

Every LLM developer ends up writing the same memory layer twice — a vector store, a summary chain, a session table, a deduper. MemoryLake replaces that stack with a single memory API that handles persistence, conflict resolution, versioning, and cross-model retrieval out of the box.

The problem: every LLM app rebuilds the same memory stack

You wire up Pinecone for retrieval, Redis for sessions, Postgres for user facts, and a custom dedupe pipeline to keep them in sync. Three months later you swap models and most of that plumbing breaks. The memory API for LLM developers should be one HTTP call, not five subsystems.

How MemoryLake solves memory infrastructure for developers

One SDK, six memory types — Background, Fact, Event, Conversation, Reflection, Skill. Stop writing custom schemas for each kind of context your app needs to remember.

REST, MCP, and Python SDK — Use it from any backend, any framework, any agent runtime. MCP support means Claude Desktop, Cursor, and Windsurf can read your app's memory natively.

Built-in conflict resolution — When new facts contradict old ones, MemoryLake flags the conflict and applies your chosen strategy: latest-source, confidence-weighted, or manual review.

Git-style version control — Branch, commit, merge, and roll back memory state. Every change has an immutable audit trail. Critical for regulated industries.

How it works for LLM developers

  1. Connect — Install the Python SDK or hit the REST endpoint. Authenticate with an API key.
  2. Structure — Send raw user turns, documents, or events. MemoryLake routes them into the right memory type and resolves duplicates.
  3. Reuse — Call retrieve() at inference time. Get a ranked, token-budgeted context block for your prompt.

Who this is for

Backend engineers, agent builders, and indie founders shipping LLM products who want to spend their time on UX and model orchestration — not on debugging memory pipelines. Especially valuable for solo and small-team developers who can't justify a dedicated infra hire.

Frequently asked questions

Is MemoryLake a vector database?

No. Vector databases retrieve embeddings. MemoryLake stores structured, typed memory with conflict resolution, versioning, and provenance. Use both together if you need document chunk retrieval plus user state.

How does the Python SDK compare to using REST directly?

The SDK adds typed memory objects, batching, and cluster-level operations. REST is fine for simple integrations; the SDK is faster to ship with for production apps.

Can I self-host MemoryLake?

Enterprise tiers support deployment in your VPC. End-to-end AES-256 encryption applies in both cloud and self-hosted modes — even MemoryLake cannot read your data.
