Profile

Hi HN,I built a voice assistant that runs entirely in the browser. No backend, no API calls. Everything runs on your device.The goal was to see how far browser based AI has come, and whether a full voice pipeline can work client side with acceptable latency.How it works - Speech to text: Whisper tiny en via WebAssembly - LLM: Qwen 2.5 0.5B running via llama.cpp WASM port - Text to speech: Native browser SpeechSynthesis APIResponses stream in real time. TTS starts speaking as soon as a sentence is generated instead of waiting for the full reply.After the first load, it works completely offline. Nothing leaves the device.Why this matters: - Shows what is now possible with modern browsers, smal

It is recorded at the Show HN launch stage.
