Who Needs SELF
SELF is for people and organizations who care about privacy and digital sovereignty
Why SELF Matters
SELF is a privacy-first AI-powered platform. Built with zero-knowledge architecture, we mathematically cannot access your data. Your conversations, memories, and messages are encrypted on your device before they ever leave your device.
Zero-Knowledge Privacy That Just Works
SELF implements zero-knowledge architecture - the server cannot access, read, or decrypt your data. Your conversations, memories, and messages are encrypted on your device before they ever leave your device. We store only encrypted data that we cannot decrypt. Maximum privacy with minimal user friction.
Your Data, Your Keys, Your Control
Passkey-based wallet system gives you complete control over your encryption keys. Your Passkey secures both encryption and wallet features, stored securely on your device. Industry-standard WebAuthn/Passkey security trusted by major platforms worldwide. You control the keys - no backdoors, no admin recovery.
Privacy Beyond Signal & ChatGPT
SELF exceeds Signal with passkey-based registration (no phone number required), user-controlled key management, and superior metadata deletion. SELF exceeds ChatGPT by encrypting AI conversations and memories with zero-knowledge architecture - the only platform that combines messaging and AI with complete privacy.
Enterprise-Grade Security, Personal Use
Client-side end-to-end encryption using AES-256-GCM, Sealed Sender privacy, perfect forward secrecy, and EU data residency. All infrastructure providers are SOC 2 compliant. Your data is protected by mathematical guarantees, not promises to be trustworthy.
SELF App
Our first product is the SELF App. This is a privacy-first AI-powered suite of communication and productivity tools. Built with zero-knowledge architecture, the server cannot access, read, or decrypt your data. Your conversations, memories, and messages are encrypted on your device before they ever leave your device.
We Cannot See Your Data
SELF uses zero-knowledge encryption. This means we mathematically CANNOT access your data:
- We CANNOT see your AI conversations
- We CANNOT see your memory bank entries
- We CANNOT see your messages or any content
- We CANNOT decrypt your data (we don't have the keys)
- We CANNOT help recover lost Passkeys (but you can create additional passkeys for redundancy)
Your data is encrypted in YOUR browser using your Passkey before it ever leaves your device. We store encrypted blobs that only YOU can decrypt. Not us, not hackers, not governments - only you. We encourage creating additional passkeys in your security settings for redundancy across multiple devices.
SELF AI
Zero-knowledge encrypted conversations. Your AI interactions are encrypted client-side before they leave your device. The server cannot decrypt or see your conversations. Personalized LLM runs on your own dedicated isolated infrastructure - your data never touches external models.
SELF Messages
Sealed Sender privacy with end-to-end encryption. The server cannot determine who sent messages. More aggressive metadata deletion than Signal - metadata deleted immediately after read confirmation.
SELF Wallet
Passkey-based wallet system. You control your encryption keys. Your Passkey secures both encryption and wallet features. Create additional passkeys in your security settings for redundancy across multiple devices. Industry-standard security using WebAuthn/Passkeys trusted by major platforms worldwide.
How Zero-Knowledge Privacy Works
Your data is encrypted on your device before it ever leaves your device. The server stores only encrypted data that it cannot decrypt.
How Private AI Works
- Your Passkey creates encryption keys stored locally
- Your device encrypts messages locally before transmission
- Encrypted Relay routes data it cannot decrypt
- AI response encrypted before storage
- Your device decrypts using local keys
How Private Messaging Works
- Your device encrypts messages locally
- Encrypted Relay routes without seeing sender (Sealed Sender)
- Recipient's device decrypts using their local keys
- Zero-knowledge: server stores encrypted data but cannot read
- Metadata deleted immediately after read confirmation
