Show HN: OpenDocBot - bring your own model to Word, Excel and PowerPoint (opendocbot.com)

OpenDocBot has been launched, introducing an open interface that allows users to integrate their own AI models into Microsoft Word, Excel, and PowerPoint without incurring additional per-user licensing fees. This tool enables organizations to leverage existing AI investments, utilizing API keys from providers like OpenAI, Anthropic, and Google Gemini directly within their Office applications. By operating within the Office task pane, the AI model utilization remains seamlessly integrated, freeing users from vendor lock-in and offering streamlined operations while maintaining document security—data does not pass through OpenDocBot's servers. The significance of OpenDocBot lies in its flexibility and control for corporate users, allowing them to self-host the solution if desired, review source code, and easily switch providers with minimal disruption. Its capabilities include document editing and data manipulation, such as cleaning up tables in Excel or building slide decks in PowerPoint, all under a user-controllable approval process. Now available in the Microsoft Marketplace for Microsoft 365, OpenDocBot is a promising development that aligns with the growing demand for customizable AI applications in professional environments.
