Ao

Ao is an open-source desktop client for Microsoft To-Do, developed by Klaus Sinani and currently at version 6.9.0 after 22 incremental releases. Built as an unofficial, community-driven alternative to the web interface, the Electron-based application wraps Microsoft’s task service in a native window while adding enhancements that power users frequently request. Its purpose is to provide quicker keyboard navigation, extensive theming, global hotkeys, and optional system-tray integration, allowing knowledge workers, students, and anyone already invested in the Microsoft 365 ecosystem to manipulate lists and reminders without opening a browser. Typical use cases include managing daily stand-up tasks on Windows workstations, capturing lecture assignments on a laptop, or maintaining a grocery list that syncs instantly with the official mobile apps. Because credentials are passed directly to Microsoft’s servers through the company’s OAuth flow, data remains within the trusted cloud, while the local wrapper simply surfaces it in a more configurable UI. The program belongs to the Productivity / Task-Management software category and is distributed under a permissive open-source license, inviting developers to audit code, submit pull requests, or fork custom variants. Version 6.9.0 refines sidebar layout, squashes Electron-level security bugs, and streamlines background sync intervals, continuing a release cadence that has delivered feature or patch updates roughly every month since the project’s inception. Ao is available for free on get.nero.com, with downloads provided via trusted Windows package sources such as winget, always delivering the latest build and supporting batch installation alongside other applications.
