A free screenshot renamer that runs on your computer

STOP SCROLLING
THROUGH "SCREENSHOT AT 3.14 PM"

Screenshot Sloth looks at every screenshot in a folder and renames it to what is actually in it, so you can find any of them later by searching. You pick the folder; it does the rest.

WHY USE IT

01

Find things by searching

Screenshots are saved with only a date and time, so finding the one you need means opening them one by one. With real names, typing "receipt" or "error" in Finder or Spotlight brings it straight up.

02

Your screenshots never leave your computer

Screenshots hold passwords, bank screens and private chats. The AI (Google's open Gemma 4 model) runs inside this browser tab on your own computer. Nothing is uploaded, and there is a button below that proves it.

03

Set it up once, then forget it

It sorts files into folders like Errors, Receipts and Travel, can move ones that look private into their own folder, and can keep watching so new screenshots get named as you take them. It is free and needs no account.

How it works in three steps: load the AI once (a one-time download), choose your screenshots folder, then check the suggested names and press Rename. Everything can be undone.

01LOAD THE AI

This puts the AI in your browser: Google's open Gemma 4 model, running on your computer's graphics chip. The first time it downloads about 3.4 GB, so use Wi-Fi. After that it opens in a few seconds, even offline.

Needs Chrome or Edge on a laptop or desktop (WebGPU).

02CHOOSE YOUR FOLDER

On a Mac screenshots land on the Desktop unless you changed it. On Windows they are in Pictures/Screenshots. The browser will ask once for permission to edit that folder.

04UNDER THE HOOD

  1. The browser opens your folder. Chrome's File System Access API lets this page read and rename files in the one folder you pick, after you allow it. Nothing is copied anywhere.
  2. Gemma looks at each screenshot. Gemma 4 E2B runs on your GPU through WebGPU and Transformers.js. It answers with a short title, a type and whether the image shows a secret.
  3. Code does the rest. The date comes from the old file name. The name is cleaned for every file system, collisions get a number, and the file moves into its folder. The model never touches a file.
Tries to send a request to an outside server from this page and from the model's worker. The browser should refuse both.

The Private folder is a convenience, not a security tool. In testing on made-up screenshots, the careful setting caught 8 of 15 that showed a password, code, key, card or ID. The other setting caught 15 of 15 but also sent 11 of 27 ordinary screenshots to Private. Do not count on either to find your secrets.
