A private AI assistant that enables users to run full-featured open-source LLMs on their devices

Sanctum

Sanctum is a private AI assistant that enables users to run full-featured open-source Large Language Models (LLMs) on their devices, ensuring data privacy and security. By processing information locally, Sanctum eliminates the need for cloud-based systems — thus reducing the risk of data breaches and unauthorized access. This approach can be particularly beneficial for professionals handling sensitive information, such as legal documents, financial data, and/or personal health records.

Sanctum integrates with Hugging Face, allowing users to access and interact with thousands of GGUF models directly through the platform. This integration means seamless downloading and utilization of various models on both PC and Mac, enhancing the tool’s applicability across different tasks and industries.

Sanctum also allows import and interact with various document formats, including PDFs, DOCX, TXT, and code files. Users can chat with AI to analyze or summarize these documents without compromising privacy, as all processing occurs locally on the device.

Sanctum provides flexible pricing plans to accommodate different user needs. The platform offers a free version with limited features, while paid plans unlock additional functionalities and support. This flexibility is there to ensure that both individual users and organizations can find a plan that aligns with their requirements and budget. Nice!
