FOLYOO GUARD

Your private way to use AI.

Let your team use ChatGPT, Claude, Gemini and more at work, without customer names, invoices or contracts ever reaching someone else's server. Folyoo Guard makes sensitive data invisible before the AI sees it.

The problem

AI is brilliant.
Data breaches aren't.

The moment someone on your team pastes a customer name, an invoice or a contract into an AI tool, that content leaves your company and sits on someone else's servers. Under GDPR that is a real risk, and most people never even notice.

Sensitive data

Names, addresses, bank details, contracts and health data flow straight into the AI.

Foreign servers

With the big providers the data often lives outside the EU.

Liability

If it goes wrong, you are on the hook, not the AI provider.

How it works

Mask, your AI, unmask.

Folyoo Guard is not an afterthought filter, it is a wrapper around your own AI. Guard replaces the sensitive parts on your side, your AI works with the placeholders only, then Guard puts the real values back locally.

MaskSensitive parts are swapped for realistic placeholders on your side, before anything leaves your company.

Your AIYour model, whichever it is (ChatGPT, Claude, Gemini or your own). It only ever sees the placeholders, with no special instructions.Never visible without Folyoo

UnmaskThe real values are put back locally in the answer. The model never saw them.

Step by step

Detect

An AI model finds names, companies, bank details, invoice numbers and more across 8 languages, including special-category data like health or salary.

Replace

Every value becomes a realistic placeholder with a stable ID.

Process

Only the protected text goes to the AI of your choice.

Restore

The real values are put back locally in the answer.

Privacy made in Germany

Built in the EU.
Compliant because nothing leaves.

Almost everyone claims to be GDPR compliant. With Folyoo Guard it is not a promise but a mechanism: sensitive content never leaves your company in clear text in the first place. Every sensitive value is pseudonymized locally before a single byte reaches an external model, and the mapping back to the original stays with you.

Data stays in the EUDetection can run entirely on EU servers.

GDPR compliantNo clear text, clear logs, full control.

EU AI Act readyDesigned for what is coming.

Fail-closedWhen in doubt it blocks, it never sends unprotected.

Security by design

Fail-closed, not fail-open.

No clear text to the AI

Only placeholders leave the service. Every request is checked first.

EU detection

Detection can run on its own EU server, so the raw text stays in the EU.

Always the same placeholder

The same value gets the same placeholder everywhere, even across messages.

Multiple layers

Patterns, AI detection and dictionaries run in parallel. Better to protect too much than too little.

Streaming & images

Live answers and the text parts of image messages are protected too.

For your developers

Your SDK. Our domain.

No AI yet? Just use Guard's OpenAI-compatible endpoint. Already have a setup? Keep your provider's own SDK, OpenAI, Anthropic or Google, and just point the base URL at Folyoo. The rest of your code stays the same.

FAQ

In short.

Do I have to rebuild my software?

No. If you already use an AI, you swap one address. If you have no software of your own, you get ready-made access.

Does the AI see my real data?

No, only placeholders. The real values are put back afterwards on your side, without any AI.

Does it work with my favourite model?

Yes. Guard is model-agnostic and sits in front of ChatGPT, Claude, Gemini, Mistral or your own model.

What about numbers and amounts?

Amounts stay intact by default so calculations work. Names, companies, bank details and numbers are replaced.
