GPTLocalhost

Overview

GPTLocalhost is a Microsoft Word add-in that lets you connect Word directly to your own local LLM servers instead of relying on cloud AI. Designed as a fully local alternative to Copilot in Word, it enables you to draft, rewrite, summarize, and analyze documents with AI while keeping sensitive content on your own machines. Once installed, GPTLocalhost adds an AI side panel inside Word where you can send selected text to your local model and insert responses back into the document with a single click. It works with a wide range of local LLM backends (such as self‑hosted APIs, GPU servers, or CPU-based local models) as long as they expose an HTTP endpoint compatible with common chat or completion formats. Because everything runs against your own infrastructure, you stay in control of data privacy, latency, and model choice. This makes GPTLocalhost ideal for organizations with strict compliance rules, developers experimenting with custom models, or power users who prefer offline or air‑gapped environments. Use GPTLocalhost to streamline everyday writing tasks, standardize business documents, assist with multilingual content, or prototype domain‑specific assistants directly inside Word—without sending a single character to the cloud.
