Who’s behind this

Hi, I’m Olexiy. I built rombik because I hated drawing flowcharts by hand — spending an hour nudging arrows in Word instead of just writing the code.

Why I built it

Anyone who studied a technical major knows this pain: your code has worked for ages, but you still have to draw a standard-compliant flowchart for it — or the review sends the whole thing back. Hours of dragging boxes and arrows so they don’t drift, only to hear “redo it, that diamond isn’t to standard.” Existing tools either ignore the standard, draw it “roughly,” or hand you a dead image you can’t fix. I wanted one thing: paste code, get the correct chart in seconds. It didn’t exist — so I built it myself, for myself first.

What I believe

Determinism over “probably-right” AI: the same program always yields the same standard-compliant chart, with no surprises the night before a deadline. An honest free preview — try it on your own code before you ever pay. And above all, a chart graders actually accept, not just “looks like a flowchart.”

Where it’s going

Next: more languages, Nassi-Shneiderman structograms, support for whole groups and departments, and reaching beyond Ukraine through the international ISO 5807 standard. The principle stays the same: less manual busywork, more time for the actual learning.

Honest and transparent
