Esper by Freysa

Esper by Freysa bridges the trust gap between humans and AI agents by enabling users to contribute verifiable web information. Using cryptography and secure hardware, users can create verifiable information that AI systems can rely on without compromising user privacy. The Esper stack supports multiple applications, from contributing verified data to AI agents to proving credentials for access gating. One initial focus is on establishing digital personhood through a simple yet robust social proof system. This system uses cross-platform verification across four key platforms:

• Verify X followers
• Verify X subscription (pre GPT-4 release)
• Verify ChatGPT subscription
• Verify Reddit karma

As part of Freysa's mission to meaningfully interact with every human being on Earth, verified data and proof systems are fundamental to establishing genuine digital personhood.
