Stateless by default
Most agents wake up blank. Context is re-explained, re-fetched, or lost between sessions.
Open-source engine
Every agent starts from zero.Give them a past.
Ultimate Memory is an evidence-grounded memory engine for agent builders. Correctness, provenance, and agent surfaces live in the open-source project — this site is the public library front, not a launched managed-product console.
Provenance-first
Memory that can show its sources — not a black-box blob.
Agent surfaces
HTTP, tools, and contracts built for agent builders.
Self-hostable
Run the open-source engine on your infrastructure.
Open on GitHub
Source, issues, and self-host path live in the public repository.
The empty-head problem
Agents forget. Builders pay for it.
Without durable, inspectable memory, every session restarts the relationship. Ultimate Memory exists so agent systems can keep a past that is grounded and operable.
Untrusted memory
Vector dumps and chat logs are not enough when correctness and audit matter.
Ops without a product claim
Builders need a real engine and docs today — not a promise of a managed console that is not public yet.
What the engine is for
Memory you can trust in production agents
01
Evidence-grounded retrieval
Answers tied to stored evidence so agents can reason with provenance, not vibes.
02
Durable organisation of knowledge
Structure that survives sessions — entities, documents, and activity you can inspect.
03
Built for agent integration
Surfaces aimed at tools and services, not only human chat UIs.
04
Open-source engine
Ultimate Memory is the library you install and run. This site is its public front.
How to start
Library path, not a fake console
01
Read the engine docs
Install, configure, and learn the contracts at the OSS documentation host.
02
Self-host the engine
Run Ultimate Memory where your agents run. No public managed console is linked from this chrome.
03
Integrate agent surfaces
Wire retrieval and memory into your agents using the published APIs and tool surfaces.
Start with the open-source engine
Read the docs, clone the repo on GitHub, and use the engine where your agents run. Managed cloud messaging stays separate and claim-gated.
