About Substrate
Work should remember itself.
We build Substrate: one shared memory for you and your agents.
Our premise
You should not have to rebuild context every time a session starts. The same memory should be legible to you and useful to every agent you choose.
Edit it
Corrections become durable facts.
Check it
Sources and status remain visible.
The standards shaping the product.
Plain claims. Inspectable memory. No promises of perfection.
Readable by people
Memory should be a document you can browse, understand, and change—not a hidden model state.
Traceable to evidence
A useful sentence keeps its sources, dates, confidence, and qualification close.
Correctable once
A human edit should become durable memory every future session can use.
Shared across agents
Your context should follow you between agents instead of resetting at every new session.

Explain it once.
