Symbiont

🌿 Symbiont

Human-AI symbiosis platform powered by Claude Code

Symbiont is an open-source platform that turns Claude Code into a living companion — one that remembers you, grows with you, and works alongside you through your favorite messaging apps.

Why Symbiont?

This is not another chatbot.

• Memory — Persistent, structured memory that evolves across conversations. Your AI actually remembers what matters.
• Personality — Swappable Persona Packs define how your AI thinks, speaks, and behaves. Make it yours.
• Autonomy — Scheduled tasks, background workers, and proactive behaviors. It doesn't just respond — it acts.
• Integration — Native Feishu (Lark) support with MCP gateway for extending to any service.
• Growth — Memory consolidation, pattern recognition, and relationship deepening over time.

Persona Packs

Persona Packs define the personality, knowledge, and behavior of your Symbiont instance.

persona-packs/
├── echo/                # Example: "Echo" persona
│   ├── persona.json     # Identity, traits, speaking style
│   ├── system.md        # System prompt template
│   ├── memory-seeds/    # Initial memories and knowledge
│   └── cron-tasks/      # Persona-specific scheduled tasks
└── your-persona/        # Create your own!

Create Your Own

1. Copy persona-example/ to persona-packs/your-name/
2. Edit persona.json with your AI's identity and traits
3. Write a system.md that defines how it should think and speak
4. Add memory seeds for domain knowledge
5. Set PERSONA_PACK=your-name in .env
