Inspired by the early CCleaner era, FluentCleaner reimagines the classic PC cleanup utility for modern Windows systems. Built with WinUI 3, it focuses on a cleaner, lightweight experience centered around removing temporary files, cache, logs, and leftover clutter - without aggressive registry tweaks, bundled extras, or scareware-style prompts.
The project also embraces the community-driven spirit that helped make older cleanup tools popular in the first place. FluentCleaner supports the well-known winapp2.ini cleaning database format, allowing it to leverage a large ecosystem of community-maintained cleaning rules while keeping the app fast, transparent, and easy to use.

- AI explanations now talk back in your language: Just switch the UI to German, French or any supported language and the answers follow automatically #79
- AI explanations works with the built-in explainer and the Custom Cleaners AI generator (Winapp2 entries & PowerShell scripts) that some of you might not have discovered yet
- Settings > AI Explanations now surfaces both features in one place so nothing stays hidden
