What is Sanctum?

Sanctum is a privacy-focused AI tool that allows users to run full-featured open-source large language models (LLMs) locally on their devices without requiring an internet connection. Developed to prioritize user data security, Sanctum encrypts all data locally using AES-256 encryption, ensuring that no information leaves the user's device. It supports MacOS (M1, M2, M3, Intel) and Windows platforms, with Linux support coming soon. The tool integrates with Hugging Face, enabling access to thousands of compatible GGUF models for diverse AI tasks. Sanctum is designed for users who need private, offline AI capabilities such as content creation, data analysis, brainstorming, and document summarization, fitting workflows that demand confidentiality and control over sensitive data.
