Overview
Socials:
Sanctum is a private and local AI assistant aimed at providing privacy-first, secure AI-based services directly on your device. The tool allows you to run and interact with full-featured open-source Large Language Models (LLMs) locally. This means that all data is encrypted and never leaves your device, offering you full control and privacy. Once downloaded, an internet connection is not required to access and use these models. Furthermore, Sanctum comes with an AI matching engine which facilitates easy switching between different open-source models, enabling users to find a model that fits their specific needs. Beyond text interpretation and generation, Sanctum also offers the ability to interact with PDF files in a private environment. This can include asking questions or summarizing documents. Finally, it is equipped with a 'Sanctum Vault' a secure local repository for data storage. All data within this vault is encrypted and accessible only by the user. While the current version supports MacOS 12+ only, future updates include plans to support Windows, Linux, iOS, and Android operating platforms.

How this was decided
Not an editorial call. The URL on file failed three consecutive
checks, with a confirmation re-probe before the streak counted (a
bot-wall response never counts as one), and the 3-miss rule marks the listing
discontinued automatically. If the URL responds again, the
registry restores it on its own: warn first, then
active. Both directions are recorded as events.
