Accumath™
No internet required. Same answers on every machine. A lifetime license that belongs to you.
Accumath is a computer algebra system with an integrated notebook (accu_book). You install it on your machine. You work offline. You keep your files.
It is written in pure Rust. Numeric work runs on SoftFloat — software floating point — so the same equation with the same inputs produces the same bit-identical results on every computer. That is not “close enough.” That is the same answer.
It is air-gapped by design: no network call to stay licensed, no cloud license server, no black-box server heuristics guessing at your math.
One lifetime license belongs to one person. All current and future updates and upgrades are free for life with that license. You may move it to a new machine, but it is good for only one machine at a time.
Version 1 is air-gap completeness: everything on the ship list that can run offline, finished and gold-checked before we call it shipped. Not a thin demo. Not “buy now, wait for the real product.”
We also ship a large equation library with the product — about half a million unique parsed equations, already typed for search and use.
Estimated ship date: January 2, 2027, if early-supporter sales fund the remaining work.
Public list numbering: built items are 1–109; still-building items continue as 110–230. See the Capabilities page.
