OpenDocBot

OpenDocBot is an AI agent for Microsoft Office (Word, Excel, and PowerPoint) that is installed from the Microsoft Marketplace. It runs 100% client-side and connects directly to the AI provider you configure, such as OpenAI, Anthropic, Gemini, DeepSeek, OpenRouter, or local models via Ollama, using your own keys or endpoints. The page states that no document data touches OpenDocBot's servers, that there are no intermediate servers, proxies, or telemetry, and that source code is public on GitHub under a fair-code license. An optional human-in-the-loop approval gate lets users review model proposals before edits are applied. Free for individuals and teams of up to 30 users; a commercial license is required beyond 30 users.
