AI memory should not be a black box.

Tietoni is built around a plain idea: the durable context AI agents know about your company should be written by people, kept somewhere visible, and controlled explicitly.

Workspaces say who context belongs to. Permissions say who can touch it. Activity shows what happened.

The name is Finnish: tieto means knowledge, -ni means mine. What my team knows — written down once, for every assistant it trusts.
