Sovereign App

Your journal, notes, tasks, and AI coach - all running on your device. Zero-knowledge encryption. No cloud reads your data. Ever.

Your notes, journal, tasks, and knowledge graph are processed by an on-device language model - nothing is sent to a server. When you turn on cloud sync, your data is encrypted before it leaves your phone with keys only you hold. We cannot read it. We cannot hand it over. That is not a promise - it is the architecture.

WHAT YOU GET

Journal with Daily Chat Talk about your day. The on-device AI turns your voice ramble into a structured journal entry and pulls out tasks and events you mentioned. Two minutes of talking replaces twenty minutes of typing.

Persona Reflection Chat with five curated personas - a Socratic coach, Marcus Aurelius, a compassionate listener, your future self, or a creative muse. Each one is a different way of thinking through what matters to you.

Notes with Auto-Linking Every note is embedded, tagged, and woven into a knowledge graph automatically. You capture; the system connects. No manual tagging required.

Tasks with Calendar Integration Due dates, priorities, recurrence, and calendar mirroring. AI suggests follow-up tasks from your notes and journal entries.

Growth Coaching Define a skill you want to develop. Sovereign watches your notes, tasks, and journal for evidence of progress and coaches you using your own words - not generic advice.

Knowledge Graph See how your ideas connect in an interactive force-directed graph. Tap any node to explore its connections. Filter by source type.

Document Scanner Multi-page OCR scanning with on-device text recognition. Every scan is automatically summarized, tagged, and linked into your knowledge graph.

Lifeline Timeline Your entire day, month, or year on a single vertical scroll. Events, tasks, and journal entries in time. The bird's-eye view of your life.

PRIVACY BY ARCHITECTURE

• On-device AI: Gemma LLM runs locally. Your prompts never leave your phone.
• Zero-knowledge encryption: Cloud sync uses AES-256-GCM with keys derived from credentials we never see.
• No tracking: No analytics, no ads, no behavioral profiling.
• No third-party AI: Your data is never sent to OpenAI, Google Cloud AI, or any external model provider.
• Exportable: Your data is yours. Export everything as an encrypted backup file anytime.

BUILT FOR PEOPLE WHO THINK

Sovereign is not another chatbot wrapper. It is a private second brain - a journal, a task system, a knowledge graph, and a coach, all backed by an AI that runs on the device in your pocket. If you have ever hesitated to write something honest in a cloud-hosted app, Sovereign is built for you.
