NeatDisk
Free Windows disk cleaner — 12 tools, no bloat, no account
What it does
NeatDisk replaces CCleaner and TreeSize with one clean, free app. Built in Rust with a Tauri UI — no bloat, no account, no telemetry. 12 tools: duplicate finder, junk cleaner, disk analyzer with treemap, driver store cleanup, disk health (S.M.A.R.T.), startup manager, app uninstaller, restore point manager, large/stale/empty file finders, and a weekly scheduler. Pro adds perceptual image matching and unlimited large file scanning.

Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
