Turn off your wifi to read on

Some thoughts you can only read alone.

The rest of this site only appears when you turn off your wifi — a small ritual that mirrors what we believe: the most personal things deserve the most personal context.

How to disconnect:
macOS — click the wifi icon in the menu bar, then "Turn Wi-Fi Off"
iOS — Settings → Wi-Fi, toggle off
Android — Quick Settings, tap the Wi-Fi tile
Windows — Action Center, click the Wi-Fi tile
What we’re building

We design local AI for the professionals who carry the privacy of others—accountants, lawyers, therapists—and our first product for everyone is an AI that helps with what matters most at the end.

For Professionals
Local AI for those who carry someone else’s privacy.
Built for work that can’t leak. Runs on your machine, owned outright, no cloud round-trip required.
Accountants Lawyers Therapists
For Everyone
An end-of-life planner for estate planning.
Our first AI for everyone, helping you sort what you’ll leave behind—documents, decisions, dignity. The most personal kind of planning, kept that way.
In development

Everything we make works offline, and is something you buy and own—not a subscription, not a service, not a server somewhere.
