Use it across tools
The same approved context can travel with more than one agent or app.
Marrow
The agentic personalisation layer
One context. Every AI.
Your work, preferences, relationships, and routines in one place.
Marrow keeps the context your tools need: how you work, what you prefer, and what you've approved. When an agent or app needs context, Marrow carries over the parts that matter for the task.

Your context, wherever you work
Share only what the task needs
Each request gets the useful slice, not a dump of everything you have collected.
Show what it used
Outputs can point back to the notes, files, or decisions they drew from.
Say what's missing
When a task needs context you have not given yet, Marrow can name the missing piece.
Reuse what you approve
Corrections and useful outputs become reusable context only after you accept them.
Keep context when tools change
Your context stays useful when the downstream builder, generator, or host changes.
