Privatim

Now in its testing phase · for the Mac

Use ChatGPT, Claude and Copilot — without client data leaving the building.

Privatim runs on your Mac. You select a text and press ⌘⌥E — and Privatim replaces names, addresses, IBANs and national register numbers with placeholders or realistic replacement names before the text goes into your AI tool. Hand the AI’s reply back to Privatim, and the real details are back in place.

Privatim’s review window: an email to an insurer in which names, address, IBAN, national register number and claim number appear as colour-coded highlights, with the legend above.
The review window: every detected detail is highlighted in colour, and the legend shows what is what. All data in this example is fictitious.

How it works

Four steps, and you keep an eye on every one of them

Privatim works in any application in which you can select text: your email client, Word, your browser, practice management software.

  1. Select

    Select the text and press ⌘⌥E. Or paste the text straight into the review window.

  2. Review

    The review window shows every detected detail highlighted in colour, with a legend. You can undo maskings or add your own.

  3. Hand it to the AI

    Copy it to the clipboard or open Claude, ChatGPT, Gemini, Perplexity or Grok directly. Via the clipboard, any AI tool works, Copilot included.

  4. Restore

    Copy the AI’s reply and restore it from the menu bar menu or with a keyboard shortcut: the real names and details are back in place.

What Privatim detects

The formats you deal with every day in Belgium and Luxembourg

Detection runs entirely on your Mac, in three layers: patterns with check digits, a language model and a local privacy model. In German, French, Dutch and English.

  • Names
  • Companies and organisations
  • Places
  • Streets and addresses
  • Email addresses
  • Phone numbers
  • IBAN and BIC
  • Structured payment references +++…+++
  • Belgian national register numbers
  • Luxembourg national identification numbers
  • Enterprise and VAT numbers
  • Belgian licence plates
  • Insurance numbers
  • Usernames, hostnames, IP addresses
  • Passwords and keys

Placeholders

Each detail is replaced with a unique, typed placeholder. Clearly recognisable, for the AI too.

Dear Dr [Person_K7QX_1], the refund will be paid into your account [IBAN_K7QX_1] …

Realistic replacement names

Names, places and companies are replaced with realistic fictitious values that AI tools handle better. Dates, amounts and identifiers remain placeholders.

Dear Dr [Hauffer], the refund will be paid into your account [IBAN_K7QX_1] …

What happens where?

Local detection. Visible control.

The AI gets the text it needs to give a good answer — not your clients’ names and numbers.

With Privatim
  • Names, IBANs and national register numbers are replaced before pasting
  • Detection runs on your Mac
  • You see every masking and can correct it
  • The mapping between real values and placeholders never leaves your device
  • The AI’s reply gets the real details back
Without Privatim
  • Client data ends up with the AI provider
  • Or: redacting by hand, line by line
  • Missed details only come to light when it’s too late
  • No overview of what was sent
  • The reply has to be translated back by hand

Why we are building this

Local detection. Visible control. Regional support.

Euregio.Net AG is a Belgian public limited company that has been working in IT, hosting and consulting since 1995. We are based in Büllingen in the German-speaking Community of Belgium and look after small and medium-sized businesses in Belgium, Luxembourg and the wider Euregio.

The idea for Privatim didn’t start at a desk. It came out of our MSVO training sessions “KI konkret” (AI in practice), where one question came up again and again: how can I use ChatGPT, Copilot or Claude in my day-to-day work when my texts contain names, addresses, IBANs or national register numbers? Most answers on the market either send that data to US cloud providers, or take too much effort for small offices.

Privatim grew out of a simple observation: data protection and usefulness shouldn’t be at odds. Local processing detects what is sensitive; visible control decides what leaves the building; and support comes from the same region as you.
