### Symphony Canvas — Native Multi-Prompt AI Canvas & Autonomous Orchestration Symphony Canvas is a high-performance, Rust-native visual canvas built for engineering, chaining, and comparing multiple AI prompts side-by-side without browser overhead. #### 🎯 Problem & Inspiration Traditional single-window chat interfaces force developers and creators into repetitive manual cycles—copying outputs between prompts, losing track of intermediate experiments, and struggling to orchestrate multi-step LLM pipelines. Existing visual workflow tools are typically bloated Electron/web wrappers that lag under load and lack deep native OS integration. #### 💡 Solution & Key Features - **Zero-Lag Rust GUI:** Built entirely with Rust (`egui`/`eframe`) using multi-threaded OS background workers over `mpsc` channels—delivering a lightweight, responsive desktop UI that never freezes during heavy concurrent inference. - **Topological Prompt Chaining:** Connect nodes intuitively with directed links. Downstream nodes automatically ingest upstream outputs with cycle prevention and topological ordering. - **3 Batch Run Modes:** Execute workflows via `Parallel` (simultaneous runs), `Sequential`, or `Chain` execution. - **AI Blueprint Generator:** Transforms a single natural language description into an end-to-end multi-node canvas pipeline (up to 12 auto-wired and laid-out nodes). - **23 Run Modes & Agentic MCP:** Combines direct LLM calls with custom Python execution, media nodes, and MCP (Model Context Protocol stdio) autonomous agents capable of dynamic tool calling. - **Real-World Notification Loop:** Native scheduling and automated completion alerts dispatched directly to Telegram, Discord, and WhatsApp. - **Privacy & Security First:** Session API keys are stored in volatile memory only by default, ensuring enterprise-grade credential security.
