Software, shipped.
Senternet is an independent software studio. We build focused, privacy-first products people use every day — and we bring the same craft to consulting for teams that need to ship.
Products we build and run
Every product is small on purpose: one job, done exceptionally well, with privacy as a default rather than a feature.
Premail
Your inbox, defended.
Our privacy-first desktop app that filters email before it reaches your inbox. Spam, recruiters, and the daily noise get handled quietly — what is left is what actually matters.

Comoji
Slack-style :emoji: autocomplete, everywhere on your Mac.
A tiny macOS menu bar app that brings colon emoji shortcuts to Messages, Mail, Notes, Safari, and most Mac apps. Type :liz, press Tab, get a lizard. Runs locally — nothing you type is uploaded.
macOS 13+ · Free · Signed & notarized
Burly
Every link, in the right browser profile.
A native macOS menu bar app that routes every link to the right browser profile — work links to the work profile, personal links to the personal one. Fast, keyboard-first, and 100% local.

StockCar
A podcast of your portfolio, not the market.
An iOS app that turns the assets you actually hold — stocks, crypto, indices, and FX — into a short, personalized audio briefing with a cast of AI cohosts. No account, no brokerage linking.

Bee Ready
Lifesaving skills, one game at a time.
Our non-profit initiative teaching young athletes CPR, AED awareness, and emergency confidence — built directly into youth sports.

All projectsThe team behind the products, on your project
We take on a small number of software consulting engagements. You get the people who design, build, ship, and operate the products above — end to end.
Product engineering
Idea to shipped product: architecture, implementation, CI/CD, and launch. We build it the way we build our own.
Native macOS & iOS apps
Menu bar utilities, full desktop apps, and iOS products — signed, notarized, and at home on the platform.
AI integration
Practical LLM features that hold up in production: agents, pipelines, and evaluation — not demos.
