For administrators looking to deploy a robust AI infrastructure without data leak risks or recurring subscription fees, Msty (formerly Msty Studio) offers a premier solution for hosting local LLMs. By serving as a centralized AI engine on your intranet, Msty allows you to curate a collection of specialized models—such as Llama 3 or Mistral—and make them instantly available to users within Microsoft Word.
As a core component of a self-hosted AI stack, Msty serves as a powerful inference engine for hosting local LLMs on your private server. By pointing LocPilot in Word to Msty’s local API, you can transform standard office computers into secure drafting engines powered by AI. This configuration ensures that while your team enjoys a seamless “Copilot-like” experience, you maintain total oversight of data confidentiality, network security, and long-term costs.

Why Choose Msty Studio for Your Local Stack?
Msty excels at providing a seamless offline experience, ensuring that your data remains private and your workflows stay reliable regardless of your internet connection.
- Local First: Msty Studio is designed to function 100% locally, protecting your sensitive data from external exposure.
- Model Flexibility: Easily toggle between various local LLMs (like Llama 3 or Mistral) to serve your intranet.
- Zero Subscription Costs: By integrating Msty with LocPilot, you can bring generative power directly into Microsoft Word without recurring monthly fees.
The LocPilot Integration
By using Msty as your local host, you can point the LocPilot in Word to Msty’s local API on your intranet. This enables a professional and secure “Copilot” experience within Word. Your team gain the ability to summarize, draft, and refine documents using Msty‘s managed models, all while maintaining complete data ownership.
🖥️ Infrastructure in Action: Centralized Inference for Microsoft Word
Watch the demo below to see how Msty can serve as the central engine, providing real-time AI inferences to Microsoft Word through the LocPilot as a local Word add-in.
The following video demonstrates core features using GPTLocalhost, our solution for individual users. LocPilot is the professional intranet edition of this technology, architected specifically for multi-user deployment in secure, air-gapped environments.
The primary architectural advantage of LocPilot is its server-client design: by hosting Msty on a single high-performance server within your intranet, you provide powerful AI capabilities to the entire office. This eliminates the need for expensive GPUs on every employee’s desk, allowing ordinary office computers to run advanced LLMs with ease.

The Intranet Advantage: Safer, Better, and Cheaper
The future of professional writing isn’t about chasing the biggest cloud model. It’s about building secure, flexible AI inside your own network. By running AI workloads on your intranet, you equip your team with powerful large language models while keeping sensitive data fully under your control. Security isn’t an afterthought—it’s built in.
An internal AI stack also gives you flexibility. When a new model emerges, you’re not waiting on a vendor’s roadmap. You can deploy it directly within your intranet and let teams choose the models that best fit their workflows—whether that’s for technical documentation, strategic planning, or creative writing.
