GDPR-proof-ish? No: proof.

Ask any model. Keep your data to yourself.

Erebus swaps personal data for placeholders before your prompt leaves, and puts it back in the answer. Use the model you want, US or not. Open source and free; Erebus Pro is a license.

How it works

Four steps, all in the Netherlands until step three.

1You send a prompt

To Erebus, with your normal API key.

2We find the personal data

Names, IBANs, addresses, phone numbers, BSNs.

3The model sees placeholders

Any model you choose. It never sees the real values.

4You get the real answer

Erebus puts the values back before you see it.
