The playground
Small tools I built because nothing else fit.
A collection of focused web apps I built myself — no engineering support — each one made to solve a real problem I, my family, or my friends had, that no existing tool was solving.

Jerebu 🌫️

Roundtable 🗣️
Most meeting-notes tools give you a transcript. Roundtable reads yours and decides what they actually add up to — one sentence naming the single thing today turns on, with everything else triaged underneath it by whether it needs you before noon, later, or not today at all. The sentence is the AI's judgment, not yours to write from scratch — and yours to overrule in one edit if it's wrong.
