AI Agent Framework with Unlimited Memory — PostgreSQL-native, self-evolving, near-zero cost

Syne 🧠

AI Agent Framework with Unlimited Memory

"I remember, therefore I am"

Named after Mnemosyne, the Greek goddess of memory and mother of the Muses.

Syne is a standalone, open-source AI agent framework built in Python. It features PostgreSQL-native memory with semantic search, an ability-based architecture for extensibility, and self-evolution capabilities where the agent can create new abilities for itself.

Why Syne?

Most AI assistants forget everything between sessions. They have no persistent memory, no learning, no growth. Syne is different:

• Unlimited memory — Semantic search over millions of memories using pgvector + knowledge graph for entity-relation traversal
• Anti-hallucination — 3-layer defense ensures only user-confirmed facts are stored
• Self-evolving — Syne can create new abilities for itself (with your permission)
• No runtime config files — No SOUL.md or CONFIG.yaml. All runtime behavior lives in PostgreSQL, changed through conversation
• Near-zero cost — Chat via Google Gemini OAuth (free). Embedding + memory evaluator via Ollama (local, $0). Entire stack can run at $0/month
• Linux-style permissions — 3-digit octal permissions (owner/family/public) for every tool and ability
• Interactive CLI — Terminal-based chat with persistent memory and tools
• Remote nodes — Extend Syne to multiple machines via WebSocket. Each node has its own CLI (syne cli), one shared memory for all, controlled from one Telegram bot
