Looking for a Microsoft Copilot alternative without recurring inference costs? You might consider utilizing KoboldCpp in combination with LLMs directly within Microsoft Word. KoboldCpp is an easy-to-use AI text-generation software for GGML and GGUF models, inspired by the original KoboldAI. It’s a single self-contained distributable that builds off llama.cpp, and adds a versatile KoboldAI API endpoint.
As a core component of a self-hosted AI stack, KoboldCpp serves as a powerful inference engine for hosting local LLMs on your private server. By pointing LocPilot in Word to KoboldCpp’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.
📖 Part of the Local AI Infrastructure Guide This post is a deep-dive cluster page within our Local AI Infrastructure Guide—your definitive roadmap to building a secure alternative to Copilot in Word with greater flexibility and a fixed-cost setup.
🖥️ Infrastructure in Action: Centralized Inference for Microsoft Word
Watch the demo below to see how KoboldCpp 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 KoboldCpp 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.
