Architecture

Crafted for Developers

Not a ChatGPT wrapper. Every layer — from agent orchestration to memory retrieval — is engineered.

Python Backend

Agent Core—Token-optimized LLM ↔ Tool multi-round loop with context compaction

Hybrid Memory—LLM semantic extraction + FTS5 full-text + sqlite-vec cosine vector search

Personality—22-state emotion FSM + energy/affinity growth, SOUL.md persona definition

Tool Suite—Shell / File / Web / Task / Animation, sandboxed execution

Task Scheduler—Async background scheduler with one-shot & recurring cron tasks

Multi-Provider—Anthropic / OpenAI / Ollama unified interface with streaming output

Desktop Client

Tauri 2.0—Rust native shell, ~15MB installer

React 18—Component UI with real-time agent event stream rendering

WebSocket—Bi-directional comms, live tool execution status feedback

Multi-Channel—Desktop pet + Telegram Bot remote access (paired auth)

i18n—Seamless bilingual switching
