About yakGPT

YakGPT is an open-source, locally running ChatGPT user interface designed to enhance the speed and interactivity of text generation. It connects directly to the OpenAI API, bypassing the official ChatGPT interface to offer faster responses. The application runs entirely in the browser, requiring no installation, and stores all state locally in localStorage without analytics or external service calls. It supports both GPT-3.5 and GPT-4 models via the user's own OpenAI API key, ensuring data privacy and security as submitted data is not used for training and is stored for only 30 days. Additionally, YakGPT integrates speech-to-text via Azure OpenAI Whisper and text-to-speech via Azure and Eleven Labs, enabling hands-free voice interaction. The interface includes a mobile voice mode and both light and dark themes.
