What WallTrek is

WallTrek is a Windows desktop app that generates AI wallpapers and can change the desktop background automatically at configured intervals. Image generation providers listed in its README include OpenAI GPT Image and Google Imagen/Gemini; OpenAI GPT models and Anthropic Claude are listed for text generation and image descriptions. Users can build prompts from configurable random elements, then search, favorite, and revisit them in prompt history. Automatic runs can use a saved prompt or generate random prompts. Optional Stability AI upscalers offer Fast, Conservative, and Creative tiers. The app can upload wallpapers to DeviantArt with generated titles and tags if optional DeviantArt credentials are configured. Prompt and image history are kept in a local SQLite database, while generated images are saved in the user's Pictures folder and include the original prompt in EXIF metadata. WallTrek is free and open source under the MIT license. It requires Windows 10 or 11, .NET 10.0 Runtime, and at least one AI provider API key; Stability AI credentials are needed for upscaling.
