What WallTrek is
WallTrek is a free, open-source Windows desktop app for generating AI-powered wallpapers and setting them automatically at configured intervals. It can use OpenAI GPT Image or Google Imagen/Gemini for image generation, and OpenAI GPT models or Anthropic Claude for text generation and image descriptions. Optional Stability AI upscalers offer Fast, Conservative and Creative tiers. Users can build prompts from random elements, search and favorite prompts, and keep a prompt history. Automatic generation can use a saved prompt or create random prompts. The app can also upload wallpapers to DeviantArt with generated titles and tags, provided optional DeviantArt API credentials are configured. Prompts and image history are stored in a local SQLite database; generated images go in the user's Pictures folder and retain EXIF metadata with the original prompt. WallTrek requires Windows 10 or 11, .NET 10.0 Runtime and at least one AI provider API key. Its project is under the MIT license.
