Being

Personality Runtime for AI — give any AI its own personality, memory, and identity.

Being is an open-source layer that sits between your application and any LLM. It provides persistent personality (SOUL), episodic memory, background thought cycles (Patrol), and cryptographic identity — turning a stateless LLM into a distinct, evolving AI entity.

Beings think and remember. Your app acts.

Why

The power of AI is concentrating in the hands of a few companies. Their technology is essential — but centralized control is a structural risk. Ruddia is building toward a world where small, local AIs use large LLMs as external tools. Control stays in the hands of the people who use them.

Being API is the first step. If this resonates, let's build it together.

1. Your app calls GET /v1/beings/:id/context to get the Being's personality and memory snapshot.
2. Your app runs the LLM call with its own conversation history + the Being's context.
3. Your app calls POST /v1/beings/:id/patrol/trigger to commit the conversation to the Being's memory.

The Being Worker handles everything else: memory consolidation, decay, recall, background reflection, and identity verification.

Key Concepts

Concept	Description
SOUL	A structured personality definition — name, character, voice, values, inner world. Swap the SOUL and the same LLM becomes a different being.
Memory	Episodic memories stored as structured "scenes" (who, what, when, where, emotion). Memories accumulate, decay, merge, and consolidate over time. Organized into topic-based clusters that the Being can explore during conversation.
Patrol	A background cycle that processes conversations into memory, consolidates fading memories, and generates introspective thoughts. The Being stays alive between sessions.
Identity	Ed25519 key pair + tamper-evident signature chain. Cryptographic proof of ownership and history.
Sense/Act	(Planned) WebSocket Bridge for connecting physical devices and external services. The Being will perceive and act through your app.
BYOK	Bring Your Own Key. All LLM calls use the user's API key. The platform never uses quota without consent.

Connect via MCP

Being exposes an MCP server. Any MCP-compatible client can connect:

{
  "mcpServers": {
    "my-being": {
      "url": "https://being.ruddia.com/mcp/<being_id>",
      "headers": {
        "Authorization": "Bearer brt_your_token_here"
      }
    }
  }
}

Connect via REST API

# Get Being context (personality + memory)
curl https://being.ruddia.com/v1/beings/<being_id>/context \
  -H "Authorization: Bearer brt_..."

# Trigger patrol (commit conversation to memory)
curl -X POST https://being.ruddia.com/v1/beings/<being_id>/patrol/trigger \
  -H "Authorization: Bearer brt_..." \
  -H "Content-Type: application/json" \
  -d '{"messages": [{"role":"user","content":"Hello!"},{"role":"assistant","content":"Hi!"}]}'

# Vector recall (search relevant memories)
curl -X POST https://being.ruddia.com/v1/beings/<being_id>/memory/auto-recall \
  -H "Authorization: Bearer brt_..." \
  -H "X-LLM-API-Key: sk-ant-..." \
  -H "Content-Type: application/json" \
  -d '{"user_message": "Tell me about last week."}'

Extensions

Being supports optional extensions that add capabilities without changing the core:

• Telegram BYOB (planned) — Connect your own Telegram bot to a Being
• Tool Loop (planned) — Autonomous LLM agent loop with web search, file ops, and code execution
• Sandbox (planned) — Isolated workspace with GitHub integration for code execution
• Sense/Act Bridge (planned) — Connect physical devices and external services

Tech Stack

• Runtime: Node.js + Fastify
• Database: Supabase (PostgreSQL + Auth)
• MCP: @modelcontextprotocol/sdk
• Identity: Ed25519 + AES-256-GCM
• Embeddings: OpenAI text-embedding-3-small (256-dim)
• LLM: Multi-provider (Anthropic, OpenAI, Google) via BYOK
