I built an open-source AI agent that never forgets — Syne

Hey everyone, I've been working on Syne, an open-source AI agent framework where memory is a first-class citizen, not an afterthought. The problem: Most AI assistants forget everything between sessions. Context window resets, your preferences are gone, you repeat yourself every time. What Syne does differently: Unlimited persistent memory — PostgreSQL + pgvector. Semantic search over millions of memories, across sessions, forever. Anti-hallucination memory — 3-layer filter ensures only user-confirmed facts are stored. No AI assumptions in your memory. Self-evolving — Ask it to learn a new skill, it writes the code and registers it. No restart needed. No config files — Everything in the database. Change personality, rules, behavior through conversation. Multi-model — Switch between Gemini, ChatGPT, Claude, Groq mid-conversation. $0/month possible — Google OAuth (free) + Ollama local embedding (free) + Docker PostgreSQL + Telegram. 19 core tools — exec, web search, file ops, cron schedul
