LocalGPT is a free, open-source Chrome extension that enables users to access the capabilities of conversational artificial intelligence directly on their own computers. Unlike many services which require data transfer to remote servers, LocalGPT ensures user privacy and data control by running entirely on the user's device. After initial setup, it can even operate offline, further guaranteeing that no data leaves the user's computer. The tool leverages the functionalities of WebLLM to provide a seamless chatting experience, using WebGPU. The performance of LocalGPT is dependent on the computational abilities of the users device. Additionally, it is crucial to note that the developer declares no usage or transfer of user data for purposes unrelated to the item's core functionality. As an extension, LocalGPT is easily accessible, making conversational AI broadly accessible in a privacy-focused manner. Refer to the source code for further understanding of the extension's operation.
