MEMORY INFRASTRUCTURE FOR AI AGENTS

Persistent memory.
Zero LLM calls.

Your context window is for reasoning. Not for memory.

Stop paying your LLM to remember things it already knew. Synapse stores memory once, retrieves only what's relevant, and never burns a token doing it. Your agent gets smarter over time. Your API bill goes down.

How it works

You're probably paying your LLM to remember things it already knew. Every context reload, every repeated summary — that's tokens. Synapse fixes that.

Write

Call POST /v1/record. Body stored in Postgres, classified by a local Gemma model. No LLM call. No token cost.

Query

Call GET /v1/query. Full-text search + semantic ranking across your agent's entire memory. Sub-100ms.

Remember

Your agent walks into every session knowing what happened before. Context that compounds.
