"I remember, therefore I am"
AI agent framework with unlimited persistent memory. Self-evolving, zero-cost setup, and it never forgets.
Named after Mnemosyne, the Greek goddess of memory and mother of the Muses.
Built from the ground up with persistent memory as the core principle, not an afterthought.
Semantic search over millions of memories via pgvector + knowledge graph for entity-relation traversal. Two retrieval systems, one shared memory.
Only user-confirmed facts stored. 3-layer filter + similarity-based insert/update/skip. Non-permanent memories decay naturally — useful ones survive, irrelevant ones fade away.
Creates new abilities at runtime — no restart, no redeploy. You ask, it builds.
No SOUL.md or CONFIG.yaml. All runtime behavior lives in PostgreSQL — change through conversation.
Free OAuth chat + local embedding + Docker DB + Telegram. $0/month, no credit card needed.
Switch between Gemini, ChatGPT, Claude, Together AI, Ollama — mid-conversation. No redeploy.
Chat via Telegram bot or terminal. Extend to multiple machines via WebSocket — each node has its own CLI, one shared memory for all.
Spawn background agents for parallel tasks. Isolated sessions, shared memory.
One command to clone, one command to configure. That's it.
# Clone and install git clone https://github.com/riyogarta/syne.git cd syne bash install.sh
install.sh handles all dependencies, creates a virtual environment,
and runs syne init — which guides you through provider selection,
Telegram bot setup, and starts PostgreSQL via Docker. No manual steps.
Use free OAuth providers and local embedding for a completely free setup.
Protected core, pluggable abilities, single-database truth.
