My laptop's AI tools were quietly using 44 GB, so I built a free tool that shows what each one is and what's safe to clear

My C: drive kept filling up. Hugging Face models (32.5 GB, including old versions I'd already updated), Claude's VM bundles (7.7 GB) and pip/uv caches (8.3 GB) were a big part of it. So I built Sparewise, a free Windows app that lists every local model with its size and last use, never deletes models itself, and clears caches that rebuild by themselves, with undo for everything. No account, no telemetry. https://sparewise.app Early and solo, so honest feedback welcome. (Not code-signed yet: More info → Run anyway.)
