MEMORY INFRASTRUCTURE FOR AI AGENTS

Persistent memory.
Zero LLM calls.

Your AI forgets everything when the conversation ends. Synapse fixes that — give any AI a permanent memory in minutes.

Your context window is for reasoning, not memory. Zero LLM calls per write.

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 self-hosted Gemma model on infrastructure we control. No third-party 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.
