Marrow

One context. Every AI.

Your work, decisions, preferences, and relationships in one place.

Marrow maintains your context independently of underlying model providers and applications.

Each connected application receives only the approved details its task requires, backed by inspectable source lineage.

Marrow Core operates as a vendor-neutral context layer, delivering task-specific user context to Claude, Codex, Lovable, personal knowledge bases, CRMs, and digital avatars with inspectable source lineage and instant correction propagation.

Your context, wherever you work.
