  description

  Esper by Freysa bridges the trust gap between humans and AI agents by enabling users to contribute verifiable web information. Using advanced cryptography and secure hardware, users can create verifiable information that AI systems can rely on without compromising user privacy.
  
  Key features:
  1. Selective web content verification: Contribute specific information from private pages
  2. Age/geography requirement attestation: Verify age/geography-related claims without exposing personally identifiable information (PII)
  3. Private message authentication: Prove message receipt without sharing content
  4. Timestamped content verification: Contribute proofs of when content was created or viewed
  5. Fine-grained access control: Choose exactly what to verify for AI agent access
  
  How it works:
  This extension operates seamlessly in the background:
  1. Browse normally while the extension runs securely in the background.
  2. The extension establishes a secure connection to the notary service on relevant webpages, and it captures the relevant data within a secure enclave.
  3. The hardware enclave verifies the data and generates a cryptographic proof.
  4. Users receive a verifiable attestation without exposing any sensitive information.
  
  Privacy and security:
  - All processing occurs within a secure hardware enclave.
  - User's private data never leaves the enclave.
  - All user data is securely deleted and zeroized immediately after cryptographic attestation.
  - No storage of personal information.
  - Fine-grained control over attestations.
  
  Benefits:
  - Enhanced AI trust: Contribute verifiable information that AI agents and systems can rely on
  - Privacy protection: Generate proofs without exposing sensitive details
  - Flexible verification: Support multiple types of attestations
  - Secure processing: Protected handling of all sensitive data
  - User control: Choose what information to contribute
  
  Esper by Freysa enables secure contribution of verifiable information to AI agents. Install now to help build trust bridges between humans and AI agents, starting with Freysa.
