LocalMode

LocalMode is an open-source (MIT) toolkit for running AI entirely in the browser with no servers, no API keys, and data that never leaves the device. It supports LLM chat with over 76 models, plus RAG and vector search. It includes Whisper speech-to-text and Kokoro text-to-speech with 29 voices, as well as on-device vision features like image classification, object detection, and CLIP search. The toolkit has a zero-dependency core with 64 React hooks and a shadcn UI registry of 107 components and 36 installable blocks. It runs on WebGPU with a WebAssembly fallback and works offline after the initial model download.
