An independent software studio · est. 2025
Software that
never phones home.
Core Arc Studio builds local-first apps for iPhone, iPad, and Mac. The AI, the indexing, and your data all run on hardware you own. Every demo on this page is computing live in your browser right now.
Push the dots around · they always come home
On-device is not a compromise.
We build software the way a machinist builds an instrument: without the pressure of venture returns, polished until it earns its place on the bench. A static page can only claim that serious software runs on your own hardware. This site demonstrates it instead, live, in your browser.
Local by default
Your data stays on your device. The cloud is opt-in, never the default. Privacy is the starting point, not a setting.
Built with intent
We don't chase trends. Every tool solves a real, tangible problem we've run into ourselves, then gets polished until it's worth shipping.
Fast or not shipped
Lightweight, responsive, and built to respect your device. Slowness is a design failure, not a trade-off we accept.
Fourteen apps. Two flagships.
Independent apps that share one ethos: local-first, private, and fast. The two powered modules below are running live; open one to operate it.
Drop a line. We read everything.
Bug report, feature wish, partnership inquiry, or a friendly hello: all are welcome. We read every message and reply as fast as we can.
