Memory-First Architecture

Built from the ground up with persistent memory as the core principle, not an afterthought.

🧠

Unlimited Persistent Memory

Semantic search over millions of memories. Never forgets, even across sessions.

🛡️

Smart Memory — Anti-Hallucination & Auto-Dedup

Only user-confirmed facts stored. 3-layer filter + similarity-based insert/update/skip. Memory stays clean, never bloated.

🧬

Self-Evolution

Creates new abilities at runtime — no restart, no redeploy. You ask, it builds.

💬

No Config Files

Everything lives in the database. Change behavior, personality, rules — all through conversation.

💸

True Zero-Cost Setup

Free OAuth chat + local embedding + Docker DB + Telegram. $0/month, no credit card needed.

🤖

Multi-Model Freedom

Switch between Gemini, ChatGPT, Claude, Groq — mid-conversation. No redeploy.

🧑‍💻

Interactive — Telegram & CLI

Chat via Telegram bot or terminal. Same memory, same tools, same agent.

🧵

Sub-Agents

Spawn background agents for parallel tasks. Isolated sessions, shared memory.
