A local platform for thought and action

Keep the source.
Change the view.

Zelf gives your notes, sources, decisions, and opportunities a continuous history—then lets focused products help you understand them and move.

The product invariant

Your context should survive every tool that touches it.

01

Originals stay visible

A summary, ranking, or rewrite never becomes the only version of what you said or found.

02

Actions stay bounded

Products help you prepare and decide. Consequential external actions require a deliberate human boundary.

03

Tools stay replaceable

Your knowledge and decisions are not hostage to one model, interface, or service provider.

The ambition

One world of thought, evidence, correspondence, and work—with many faithful ways to see it.
