Equational Applications

Give your AI a memory that stays.

Agentic memory as a service — persistent, searchable, and yours.

SynapseTree is the flagship product from Equational Applications: a hosted memory service built on the same open-source engine we publish as MIT-licensed npm packages. Your agents get per-tenant memory databases, hybrid retrieval, and inference on your own keys — and our consulting team is available if you want it wired into your stack.

What you get

Per-tenant memory databases

Every tenant gets its own SQLite database on durable object storage. Your memory is a plain file — exportable, portable, sovereign.

Hybrid retrieval

Knowledge-graph retrieval fused with semantic and keyword search, tuned so agents surface the right fact without prompt gymnastics.

Bring your own inference

Extraction and query embeddings run on your Anthropic, OpenAI, AWS, or local keys. No token markup, no lock-in to our models.

Portable by design

Import and export your entire memory as Open Knowledge Format files or raw SQLite dumps. No export fees, no lock-in, on any plan.

Frequently asked questions

What is SynapseTree?
A hosted memory service for AI agents. Agents read and write facts, events, and documents to a memory pool that persists between sessions — per-tenant, searchable, and portable.
Can I self-host?
Yes. The core engine is open source under the MIT license and runs anywhere SQLite does. The hosted service adds cloud sync, team sharing, and multi-device persistence.
Do I have to bring my own API keys?
No — but you can. SynapseTree is bring-your-own-inference first: extraction and embeddings can run on your Anthropic, OpenAI, or AWS keys, or on managed defaults.
How do I leave?
Anytime. Export your entire memory as Open Knowledge Format files or raw SQLite dumps. No export fees, no lock-in, on any plan.
Who builds it?
Equational Applications — the team behind Clanker AI and the open-source LLM Wiki Memory libraries. Consulting is available if you want SynapseTree wired into your stack.

SynapseTree runs on the open-source memory engine behind LLM Wiki Memory and powers the memory in Clanker AI.
