Coming Soon — AI Privacy Layer

Use AI freely.
Keep your data yours.

Limen is the privacy layer between your team and the LLMs you rely on. Use ChatGPT, Claude, Gemini — without your sensitive data ever reaching them.

No spam. Just early access when we launch.

You're on the list.

We'll be in touch when Limen is ready.

Redact Before It Leaves

Limen automatically detects and masks PII, API keys, credentials, and sensitive business data before your prompts reach any LLM provider.

Any Model. Full Control.

Works with ChatGPT, Claude, Gemini, Copilot, and open-source models. One privacy layer across every AI tool your team uses.

Ship AI, Stay Compliant

Meet privacy regulations without slowing down adoption. Full audit trails, data governance, and policy controls — built for teams that move fast.

How it works

How LIMEN Works

LIMEN sits between your app and AI providers. Sensitive data never reaches the model. Responses come back complete. Your team doesn't notice a thing.
