WondayWall

日本語 | English

A personal wallpaper app for Windows that generates wallpapers based on your schedule and interests.

WondayWall uses Gemini API to generate wallpapers from your calendar events, RSS news, and interest keywords. Instead of showing a simple slideshow, it brings a scene that reflects your day to your desktop.

Requirements

• Windows 10 / 11
• .NET 10 Runtime
• Google Calendar integration
• Google AI API key

Setup

1. Download WondayWall-(version).msi from the releases page
2. Run the downloaded MSI and follow the installer prompts
3. Launch the installed WondayWall app to open the setup screen
4. Configure your Google AI API key
5. Authorize Google Calendar (a browser opens during the first setup)
6. Register your interest keywords and RSS feed URLs
7. Use "Generate now" to verify that wallpaper generation works

For scheduled updates, select runs per day in the app settings and register the following command in Task Scheduler.

WondayWall.exe run-once

• Run times are fixed slots that divide 24 hours evenly
• Examples: 1 run is 0:00, 2 runs are 0:00 / 12:00, and 4 runs are 0:00 / 6:00 / 12:00 / 18:00
