ChatGPT, Claude, Gemini or internal: Psoydo sits in front of every AI and turns real identities into consistent tokens. The key stays with you.
Every option so far forces a trade-off. Psoydo is the first to deliver all three at once.
But personal data and trade secrets leave the building.
But performance lags miles behind the leading models.
Pseudonymisation before every AI interaction. Economical, local, compliant, and always the best model for the task.
Every document passes through Psoydo first. Only then does the AI see anything, and never a real identity.
All files and mails of a case are processed together. Each person gets exactly one consistent pseudonym, across every document.
AI and rule-based detection separate person from company, month from name, technical term from personal data. No blind find and replace.
Not a single byte leaves your infrastructure. No cloud, no external APIs, full data sovereignty. The key always stays with you.
The same word can be a person, a company, a place or a date. Only real contextual understanding can tell them apart. That is exactly what Psoydo does.
One word, four times, each time something different. Rigid rules fail here. Psoydo recognises the role in context: same word, different role, different pseudonym.
No automated system is flawless. Psoydo makes errors visible, understands them and gets better with every case. In the end, a human always decides.
Pre-flight analysis and pipeline pseudonymise the case.
Match list and risk candidates surface every borderline case.
The root cause is clarified and fed back into the system.
The final, deliberately human check before release.
No AI know-how needed. Pseudonymised text and matching prompt, paste both, result ready instantly. Afterwards the real identities are restored.
Psoydo does not come from an AI startup that stumbled onto compliance by accident. Over 120 companies trust wescaleIT when it comes to their information security.
For us, compliance is not a box ticked at the end, it is built in from the very first line of code. Psoydo withstands audits, reviews and the scrutiny of your data protection team, because we know these checks from daily practice.
Psoydo protects not only personal data under GDPR, but also your trade secrets under the German Trade Secrets Act (GeschGehG). Each layer is steerable on its own.
Built for the strictest requirements: GDPR, trade secrets, KRITIS and defence.
Processing exclusively in your own infrastructure. No data transfer to the outside. Suitable for KRITIS and defence.
Mathematically reproducible rules based on SHA-256. Same input, same pseudonym. Fully auditable.
Every step documented, immutable hash chains. Seamless for audit, compliance and certification.
German, English, mixed. Unsupported languages are flagged, no silent failure.
For each of these industries there are ready-to-use presets already. Detection and pseudonymisation are tuned to your domain from day one.
