I built Syne because I was tired of AI assistants that forget everything after each conversation.Syne is a self-hosted AI agent framework where memory is a first-class citizen — stored as semantic vectors in PostgreSQL, searchable across millions of entries, and persistent forever.Key features: - Unlimited persistent memory with semantic search (pgvector) - Anti-hallucination: only stores user-confirmed facts, auto-deduplicates - Self-evolving: creates new abilities at runtime without restart - Multi-model: switch between Gemini, ChatGPT, Claude mid-conversation - True $0/month setup: free OAuth + local Ollama embedding + Docker - 19 core tools, sub-agents, Telegram + CLI interfacesBuilt with Python, PostgreSQL, and Docker. No vendor lock-in.GitHub: https://github.com/riyogarta/syne Landing page: https://syne.codes

Could you build this?
Yes Building an AI agent memory system using PostgreSQL with the pgvector extension and an LLM orchestration layer is a standard, well-documented architecture that AI coding assistants excel at.
