The trusted
knowledge layer
for a world
run by agents.

Kyyn gives an AI agent somewhere durable to curate what it learns — from mail, meetings, files, and the systems you use. It proposes changes; you review the actual diff; only accepted, validated facts become part of the base.

Any repo's tree, local or remote, at a ref — glob-swept.
Salesforce
A SOQL query's records as a standing evidence source.
Kyyn KB
Read another KB as evidence — federation without a shared ontology.
What people build with it
An operational memory

Who it serves, why it exists, and a live todo list — grown from mail, calendar and transcripts. The inbox is evidence; the KB is the concise, current memory.

A KB in your vocabulary

Research project, product catalogue, family archive, investment thesis — the schema travels with the KB, no domain compiled into Kyyn itself.

A curated sales view

Curate only strategic accounts and material opportunity changes from Salesforce — the translation happens at the normal review seam.

Trust, enforced — not promised
The full trust model →
One binary, no builds
Validators and plugins run as WebAssembly components inside kyyn itself. Consuming a KB needs no toolchain, no sandbox packages — Linux and macOS alike.
The tree carries its judge
The validator that accepted a commit is committed with it. Any machine replays the exact predicate — same tree, same verdict.
Plugins can only do what they import
A plugin's typed import list is its entire authority — checked before it runs. Network egress only to hosts you consented to.
Secrets stay with the host
OAuth and API credentials are attached by the engine, outside plugin memory. A compromised plugin has nothing to leak.
