We give part of the work away for nothing
Not out of charity and not in exchange for your email. The tools we wrote every day for our own tasks are cheaper to open up to everyone than to keep in a drawer. There will be no sign-up, no quantity limits, and no paid tier either.

In 2026 Ukraine is switching to a new activity classification. There's no automatic transition: every sole proprietor has to figure out their new code on their own, and the official correspondence tables are hard for a human to read. We built a service where an entrepreneur enters their old code or uploads an extract from the registry and gets an answer in a minute.

What we use ourselves
The "browser" tag means the computation happens on your computer and the files go nowhere — that matters for server logs and catalog feeds.

Another 4 tools are written but don't work: they're blocked on paid keys to third-party services and Google verification, not on code. We'll add them here as we launch them.
Not every job has a price
A task breakdown before the quote
We look at the site and tell you what's actually wrong with it. If you don't need the service, we say so in the first email — not after payment.
Public services
When a task affects many entrepreneurs at once — like the switch to NACE — it's cheaper to build one open service than to explain it to each person separately.
Projects with no budget
We take them selectively and under the same contract as paid work: scope, deadlines, acceptance by act. Without a contract we don't work — for money or without it.
