Local AI cost calculator
Weigh running AI on your own hardware against paying for an API. It shows what stays local, what still goes to the API, and whether the hardware pays for itself.

What we build for ourselves.
Client work comes first. Between projects we build our own tools and apps: small, real, and shipped to the same standard as the work we deliver.
Web tools
Free to use, and useful before anyone talks to us.

An MCP server that replaces a coding agent's file and shell tools with one Go binary. Released under GPL-3.0-or-later.
Open source

Blink
A privacy app that runs entirely on the device. No data collection, no accounts and no analytics.
On Google Play
Visit the Blink siteLocal-first, and honest about the exceptions.
Your countdowns, dates, attachments and settings stay on your device. Cloud backup, where a plan offers it, writes to an account you already own rather than to a server of ours. Where an app sells a subscription, it is a plain yearly plan handled by RevenueCat on the store's behalf, and it never creates an account with Factor IO. Each app states precisely what it sends, to whom and for how long in its own privacy statement, because a promise like this is only worth something if it is specific enough to be checked.
