THE ECOSYSTEM

This started with one tool. Then it got out of hand.

What started as one script to stop me losing context across 18 terminals turned into... all of this.

Every tool talks to the others. Tap any card to explore it.

WRITING

Notes from the build.

FEATURED

I built Craft for myself. Now it's running me.

I sat down to save what was working. Four months later it's a harness, and I'm not sure who's running who.
