Fifteen Chrome add-ons for Czech and European businesses. Check a company on an invoice, margin on Allegro, deadline in the data box (official electronic mailbox), competitor price on Heureka — without opening another window or retyping.
We build in order of interest. The first add-ons launch in October 2026. If you get in touch now, you get the first month free.
Why an add‑on, not another program
Most work in a small business today happens in the browser: invoicing software, shop administration, data box (official electronic mailbox), marketplace, email. Each is good at its own thing and knows nothing about the others.
A Chrome add‑on sits over all of them at once. You select the company ID on an invoice and see the insolvency register. You open your offer on Allegro and see the margin after fees. Nothing is retyped, nothing opens in a new window.
Each add‑on does one thing, installs in a minute and can be turned off with one click. You pay only for the ones you use.
Fifteen add‑ons

Unlock with a key
Pay by card, you receive an email with the key, enter it into the add-on. The invoice arrives automatically; you can cancel the subscription anytime.
Four rules that apply to every add‑on
- Only public data and official interfaces ARES, insolvency register, VIES, contracts register, API Allegra. We never bypass terms, so no one can block your account.
- Your data stays with you Invoice, message and order contents never leave your browser. Only the licence and what you explicitly enable (monitoring) come to us.
- Nothing is sent without you The add-on fills in, shows and monitors. You always press the Send button.
- If the target site changes, we fix it the same day Each add-on has an automatic test against the live site every morning.
