Description
Limen is a browser-based privacy product that protects sensitive information at the point of AI use. Its extension performs on-device detection of personal data, credentials, regulated identifiers, and user-defined protected terms, then provides redacted content for AI services while original values remain on the device. It supports destination-specific controls and metadata-only, hash-chained audit events, and currently supports ChatGPT, Claude, Gemini, Perplexity, Microsoft Copilot, localhost, and Open WebUI-style interfaces.
