Sanctum offers a private and local AI assistant that prioritizes privacy and security by running full-featured Large Language Models (LLMs) directly on your device. All data remains encrypted and never leaves your device, ensuring complete control and privacy without the need for an internet connection. With an AI matching engine, users can easily switch between open-source models to find the best fit for their needs. Beyond text interpretation, Sanctum allows interaction with PDF files in a secure environment, enabling tasks like asking questions or summarizing documents. The 'Sanctum Vault' provides a local repository for encrypted data storage accessible only by the user. While currently available for MacOS 12+, future updates will extend support to Windows, Linux, iOS, and Android platforms.
