AI Proxy · Swiss Hosting
Use AI on client files in nLPD compliance
Your team can query Claude on real client matters without exposing personal data: anonymization runs locally in Switzerland, the transparency panel shows exactly what is sent to the AI, and responses are reconstituted with real names for day-to-day firm work.
What is aiproxy?
aiproxy is a Swiss-hosted artificial intelligence proxy designed for law firms and fiduciaries. It lets you query Claude (Anthropic API) on sensitive data while ensuring no identifiable personal data leaves your infrastructure without prior anonymization.
- Local anonymization Presidio (local, open-source) enhanced with Swiss recognizers (social security numbers, IBAN, phone, case references)
- Full transparency Mandatory preview and selective de-anonymization before each send. Response mapping and de-anonymized display of results.
- Zero install Browser-based web application, no software on workstations
- Data sovereignty Processing and hosting on Swiss infrastructure (Infomaniak VPS)
How it works
Local anonymization
Presidio detects and masks persons, social security numbers, contact details, IBAN and case references before any send.
Transparency & send
The nLPD panel shows the pseudonymized text actually sent to Claude. The user validates before sending.
Reconstituted response
Claude replies based on anonymized text; tokens are automatically replaced with original data.
Our approach
Every project starts with a personalized demonstration. The pilot phase follows once the approach is validated with your team.

Frequently asked questions
What is the nFADP (nLPD) and why an AI proxy?
The revised Swiss Federal Act on Data Protection (nFADP, formerly nLPD) governs the processing of personal data in Switzerland. An AI proxy like aiproxy lets firms use cloud models (Claude) while ensuring no identifiable data leaves your infrastructure without prior anonymization and user-facing transparency.
How does aiproxy anonymize data before sending to Claude?
aiproxy uses Presidio, an open-source engine running locally on the Swiss server. It detects and replaces names, social security numbers, IBAN, phone numbers and case references with pseudonym tokens. The user sees the exact text sent to Claude in the nLPD transparency panel before validation.
Where is data hosted?
Anonymization and the application are hosted on a dedicated VPS in Switzerland (Infomaniak). Only already pseudonymized text is sent to Anthropic's Claude API. No identifiable personal data leaves the infrastructure without prior masking.
What document types are supported?
Users can enter free text or upload DOCX and PDF documents (including scanned PDFs via OCR). Content is anonymized locally before any send to the AI.
Is aiproxy suitable for law firms and fiduciaries?
Yes. aiproxy was built for Swiss law firms and fiduciaries handling sensitive client matters. Swiss recognizers (social security numbers, CH IBAN, case numbers) and the nLPD transparency panel address the compliance needs of these professions.
How do I get a demo?
Click "Request a demo" and fill in the form. We will contact you within 48 business hours to schedule a personalized 20-minute video call — no commitment and no signup required.
What is the difference between the free demo and the paid pilot?
The demo is a 20-minute presentation on a concrete use case from your practice, without access to the application. The pilot is a paid phase after the demo: dedicated instance on your Swiss VPS, user accounts, document upload and onboarding support.
