DownloadsSloth: a local Gemma tool that tidies messy folders so you don't have to

Description and use

DownloadsSloth uses a local Gemma 3 4B model to automatically rename and categorize files in a Downloads folder, preserving originals and offering undo.

Problem

Sorting a Downloads folder with hundreds of unnamed or poorly named files is tedious and time‑consuming.

Outcome

On a test set of 44 files, Gemma produced suggestions in 141 seconds and applying changes took under a second.

Workflow

• Provide absolute path to the target folder
• The tool scans files read‑only and sends metadata to Gemma 3 4B via Ollama
• Gemma returns JSON suggestions (new name, folder, reason, confidence)
• User reviews the table, edits names, checks desired rows
• Press apply to copy approved files into a new output folder
• Undo can revert the copies if needed

Evidence

DownloadsSloth does the boring part. You point it at a folder, and Gemma 3 looks at each file and suggests a clearer name and a folder (Photos, Screenshots, Documents and so on).

Source

Gemma produced suggestions for all 44 files in 141 seconds, unattended.

The scan is read‑only, only works inside my home folder, and refuses system folders, ~/Library and hidden folders.
