Hi, my name is Javier and I "program" by describing what I want in plain Spanish/English and hoping Claude understands me. It compiles, therefore I am a developer. That's the whole résumé.

Started this because my brother needed something visual to study chemistry and physics. One tool became a hundred and fifty. I have never written a line of code that wasn't first written by an AI and then broken by me trying to "just tweak one small thing."

It's apexapro.com. Free tools, no sign-up, and yes, some of them still have bugs I found out about via Reddit comments, which is a special kind of pain.

If anyone here also vibes their way through a codebase they don't fully understand, would love feedback (or solidarity).

What it is: a growing collection of free, interactive calculators and tools covering everyday stuff (unit/currency-adjacent conversions, finance, health), science (physics simulators, chemistry, astronomy calculators), and a kids/learning section. Everything runs client-side in the browser, no account needed.

Who it's for: anyone who wants a quick answer without digging through ad-heavy sites or creating an account just to convert a number. Also useful if you're a student, since a chunk of the science tools include visual simulators, not just plain calculators.

Why it stands out: built solo by a non-programmer using AI, so the whole thing grew organically based on real needs rather than a pre-planned product roadmap. That means depth varies across tools (still actively working through that), but it also means new tools get added fast when there's a clear use case.

My brother's in high school and needed something more visual to study chemistry, physics, and math. I used Claude to build him a simple site with interactive calculators and visualizers. I'm not a programmer or from a tech background, so without AI this probably wouldn't have happened, at least not this fast.

It ended up helping him a lot more than I expected, so I kept expanding it. Added a bunch of other free calculators and tools along the way (finance, science, everyday stuff). Now trying to figure out if it's worth growing into something bigger, or if I'm overextending it, so genuinely looking for feedback here, not just upvotes.

Everything's free, no sign up, runs in the browser. What's useful, what's broken, what would you cut or add?

Hice una web con ayuda de claude para ayudar a mi hermano que está estudiando en la media a estudiar algunas cosas. No soy programador ni del area informatica, entonces sin la IA no hubiese sido posible o al menos no en tan poco tiempo.

Mi hermano necesita algo más visual a veces y le ha ayudado harto con cosas como química, física y mates

La cosa es que igual después la amplié a otras herramientas, weas varias, etc. A ver si crece la página y puede ser útil

Me podrían dar su opinión? O sugerencias de qué agregar o sus críticas?
