Proof

Status, source, and operating context

Inspectable
The approach

Every tool is built from real workflows, tested in production, and made to disappear into how you already work.

Built native

No external apps to break. Skills run on Notion AI; AV tools run offline in your browser.

Documented

Every product ships with a setup guide and architecture notes — know what you use and why.

Modular

Use standalone or connect together. Shared naming means everything clicks into place.

No subscriptions

Buy once, get updates as platforms ship features. Widgets and AV tools are free.
