About Sophon
Named after the proton-sized supercomputer from The Three-Body Problem, Sophon embodies immense intelligence in an elegant package.
Our Mission
We believe AI assistants should be personal, private, and powerful. Too many tools today fragment your attention across dozens of apps, each with its own login, its own data silo, and its own limitations. Sophon exists to unify your digital life under a single intelligent layer — one assistant that works across every channel, remembers everything you need, and acts on your behalf with your explicit permission.
Our Vision
We envision a future where every individual and organization has access to an AI operating system that truly understands them — their preferences, their workflows, their goals. Not a chatbot that forgets you after each session, but a persistent digital partner that grows with you. Sophon is model-agnostic, runs on your infrastructure, and keeps your data exactly where you decide. No vendor lock-in. No data harvesting. No compromises.
What Sophon Can Do
Omni-Channel Messaging
One assistant across WhatsApp, Telegram, Discord, Slack, Teams, Signal, Email, Matrix, SMS, and WebChat — unified under a single conversation.
Persistent Memory
Sophon remembers your preferences, projects, contacts, and context across every conversation. Short-term daily logs and long-term curated knowledge work together.
Multi-Agent Runtime
Create purpose-built agents with distinct personalities and capabilities. Route messages automatically to the right agent based on context.
Workflow Automation
Build complex automations visually or through natural language. Triggers, conditions, loops, approvals, and 20+ node types — all orchestrated by AI.
Document Intelligence
Upload PDFs, DOCX, spreadsheets, images, and audio. Sophon extracts, summarizes, indexes, and lets you query your documents conversationally.
Sandboxed Code Execution
Run C# and Python code safely in isolated containers. The agent can write, test, and iterate on code without risking your system.
Extensible Skills & Integrations
Connect to Google Calendar, GitHub, Notion, Jira, and hundreds more. Install skills from the marketplace or let the agent author its own.
Human Approval Gates
Every sensitive action — sending emails, modifying data, executing code — requires your explicit approval. You stay in control.
Our Security Pledge
Security is not a feature we bolt on — it is the foundation Sophon is built upon. Every design decision starts with the question: what is the safest default?
- Zero-default-access: Sophon ships with no pre-configured LLM providers or external connections. You explicitly choose what to connect and what data to share.
- Encrypted credential vault: All API keys, tokens, and secrets are encrypted at rest. The AI agent never sees raw credentials — a brokered pattern keeps secrets out of the LLM context entirely.
- Sandboxed execution: All code runs in isolated containers with resource limits and network restrictions. Skills from the marketplace undergo automated security scanning before publication.
- Human-in-the-loop: Destructive or sensitive actions always require your explicit approval. Timeout means reject — Sophon never assumes consent.
- Your infrastructure, your data: Self-host on your own servers. Your conversations, memory, documents, and credentials never leave your environment unless you choose otherwise.
