BigInt arithmetic without floating-point inaccuracies
det(A) = 2(4·(-3) - 5·2) - (-1)(0·(-3) - 5·1) + 3(0·2 - 4·1) = 2(-22) + 1(-5) + 3(-4) = -44 - 5 - 12 = -57

Every fold is a decision.
Software shouldn't feel like a predatory rental or an attention trap. We operate with art-gallery restraint, industrial rigor, and architectural clarity.
Purity of Purpose
Each product is built around a singular domain—whether manipulating PDF pages, mastering arithmetic, or solving matrix systems. No bloated all-in-one dashboards or irrelevant feature creep.
On-Device Dignity
Your personal documents, student sheets, and calculations belong to your hardware. Core functions execute locally without forcing sign-in, remote telemetry harvest, or cloud uploads.
Uncommon Care
We obsess over typographic hierarchy, exact mathematics without rounding flaws, and responsive interfaces that perform reliably on both modest and flagship mobile devices.
