The calculations people actually live by — how many Schengen days are left, how close FIRE is, how many calories a body burns — live in cluttered sites full of ads and sign-up walls. The answer is buried under the noise.

CalcAtlas

We built CalcAtlas as a small atlas of calculators — Schengen 90/180 tracking, FIRE planning and TDEE — all running locally in the browser, with instant results and zero uploads. Each one is one screen, one answer, done.

Every PDF tool asks you to learn its panels, sign up for its account, and wade through its ads before you can do the one thing you opened it for. People spend more time fighting the tool than finishing the document.

PDF

We built a single quiet browser workspace where merge, split, compress and convert sit one glance away. Everything runs in place, files stay local, and the interface recedes so the document becomes the interface. The whole product fits on one screen because the job usually does.

The frontier of AI lives behind API keys, dashboards and rate limits. Curious people — writers, makers, small teams — want to try models, compare them, and pick the right one, but the tools are built for engineers, not for thinking.

AI Model

We built a single interface that runs a question across multiple models side by side, surfaces the differences plainly, and keeps a running conversation instead of a wall of transcripts. No keys, no billing forms — the models are just there, ready to think with you.
