Slothshot: it sorts your screenshots overnight, and it will never delete one

Description and use

Slothshot automatically sorts screenshots on a computer overnight, never deleting files and keeping all processing local to protect privacy.

Problem

Users accumulate many unnamed screenshots containing sensitive data, making manual organization tedious and risky.

Outcome

In 101 seconds, 28 screenshots were sorted into six categories with 75% accuracy for the default model and 89% for the optional higher‑memory model. No files were deleted; sensitive text was never indexed. Undo restored all files to their original names and locations.

Workflow

• 1. Run Slothshot while the laptop is idle and plugged in.
• 2. The program loads a chosen vision model locally (default qwen3-vl:2b-instruct, optional gemma4:e4b).
• 3. Each screenshot is processed by the model to produce a JSON description.
• 4. The program creates a journal entry, moves the file to the appropriate category folder, and marks the entry applied.
• 5. If any move cannot be undone, the entire run aborts and reports "Nothing was changed".
• 6. After completion, a summary reports sorted count, items in Review, and potential space freed.
• 7. Optional: run the undo command to restore all files to the original top‑level folder with original names.

Evidence

Slothshot sorts the screenshots piling up on your computer while you are not using it. Overnight, while the laptop is idle and plugged in, entirely offline, on Windows, macOS and Linux.

Source

An open-weight vision model reads each one on your own machine, gives it a name you can recognise, files it by what it is, and leaves a Review pile for the duplicates and the things that have expired.

Source

It never deletes a file. Not duplicates, not expired items, not anything. They move to Review, where you decide.

Source

Sensitive screenshots are sorted but never indexed. If a screenshot shows a password, a card number, bank details or a one-time code, its text is not stored at all.
