With AI writing more of our boilerplate, I wanted a fast way to keep my own distributed systems instincts sharp, so I baked sysd. You sketch architectures on Excalidraw (Free-Flow or across 11 canonical prompts) while a live DB writes or missing presigned offloads, and stamps multi-plane Staff+ reference blueprints with capacity math onto the board. Hands-free voice mode runs 100% locally in Web Workers with zero API keys using wasm-vad, Cactus Whistle (16.9 MB WASM) for 16 kHz speech transcription biased toward your drawn box labels, Cactus Needle 3 (35.3 MB WASM) for grammar-constrained canvas tool calls, and Kokoro-82M (WebGPU fp32 / WASM q8) for 24 kHz Socratic voice follow-ups with instant barge-in.
