🎯 Goal

Build a privacy-first personal organization platform that consolidates notes, passwords, documents, and AI assistance into a single app β€” with end-to-end encryption ensuring only users can access their data.

πŸ’‘ Outcome

A 5+ year partnership that grew from 1 developer to a team of 8. Together we delivered the world's first encrypted AI "everything app" with zero-knowledge architecture, on-device AI processing, and a comprehensive feature set that replaces 20+ standalone apps.

How It Works

This encrypted personal command center protects everything you store with zero-knowledge encryption β€” not even the company can see your data.

1

Store Everything

Notes, passwords, documents, photos, health records, family information β€” all in one secure place protected by military-grade encryption.

2

On-Device LLM

Edge AI processes information securely on your device. The patented LLM learns from your documents to generate smart insights β€” all processing stays local.

3

Sync Securely

Real-time encrypted backups sync across all your devices. Your data travels encrypted end-to-end β€” unreadable to anyone but you.

4

Share Selectively

Share specific items with trusted contacts while maintaining complete control. Perfect for families managing shared information securely.

Key Features We Built

πŸ” True Zero-Knowledge Encryption

Real end-to-end encryption with unbreakable cryptography where only users hold the keys. Not even the company can access user data β€” encryption keys never leave the device. Real-time encrypted backups sync across devices while maintaining complete privacy.

πŸ€– Patented On-Device LLM

A completely private, patented edge AI assistant that processes data directly on the device. The LLM learns from user documents to generate custom reminders and personalized insights β€” understanding personal context like medical conditions and important dates β€” all without any data leaving the device or third-party access.

πŸ“„ Encrypted Document Vault

Scan, upload, and organize important documents β€” from wills and contracts to medical records and insurance cards. All encrypted, searchable, and accessible only by the user with their private keys.

πŸ₯ Private Health Dashboard

Store medical records, prescriptions, and even DNA sequencing data in a zero-knowledge environment. A secure health repository where sensitive health information remains completely inaccessible to anyone but the user.

We build secure mobile apps with encryption, on-device AI, and privacy-by-design architecture.

About the Client

A San Francisco-based stealth-mode startup focused on building the future of private, personal organization. We've worked together for over 5 years, expanding our team from 1 to 8 developers as the product grew. Their mission is to give people complete control over their digital lives.

The Challenge

  • Implementing true zero-knowledge encryption while maintaining app usability
  • Running AI models on-device with limited mobile computing resources
  • Secure cross-device sync without server-side data access
  • Building a unified experience replacing 20+ separate apps

Under the Hood

Tech Stack

Swift and Kotlin for native iOS and Android development, Node.js backend with end-to-end encryption, Core ML and TensorFlow Lite for on-device AI, and secure cloud infrastructure for encrypted sync.

Patented On-Device LLM

Patented edge AI architecture with Core ML on iOS and TensorFlow Lite on Android. The on-device LLM learns from user documents to understand personal context β€” medical conditions, important dates, financial details β€” generating custom reminders and personalized insights. All processing happens locally with zero third-party access.

Patented edge LLM runs locally on-device, learning from documents to provide personalized insights without any external data sharing.
