Get started
Governed memory in a few lines.
Self-host the open-source core today. Pick your surface — the library, a containerized MCP server, or an MCP client config — and you’re running with provenance and policy on by default.
The embedded library. Remember and recall in a few lines, governed by default.
pip
python -m pip install "heartwood-memory[recall,mcp]"
from heartwood import Heartwood
hw = Heartwood(path="./heartwood.db", tenant="tenant:acme")
hw.remember(
"Refunds over $500 require finance approval.",
subject="policy:refunds",
created_by="agent:support",
)
results = hw.recall("what is the refund policy?", principal_id="agent:support")1
Review
Read the docs and the executable proof. Run the trust suite yourself — every governance claim is a gate you can re-run.
2
Provision
Pick a tier and provision a license, or start free and self-host. Keys are issued to your email; your data never leaves your environment.
3
Build
Install the library, point it at your data, and ship agents that retrieve under policy, cite their sources, and prove deletion.
