Welcome to Sieve
Sieve is a free, open source app that automatically classifies and organises your images using AI.
You give it a folder of images and a list of labels. It goes through each image, decides which label fits best, renames the file, and sorts it into the right folder — all on your own device, using your own AI key.
No accounts. No subscriptions. No cloud storage. Your images stay on your machine.
What Sieve is great at
Sieve works well for research — organising microscopy images, gel photos, cell cultures, and experimental specimens. But the underlying idea is simple enough to work for almost anything. If you can describe what you want to sort into a list of labels, Sieve can sort it.
A few examples of what people use it for:
Sorting hundreds of microscopy images into folders by organism or technique
Organising field photography by subject or species
Classifying product images by type or condition
Separating vehicle photos by make or model
Any situation where you have a lot of images and a clear set of categories
If you have a use case in mind that isn't listed here, it will likely still work. See Using Sieve for Anything for more.
How it works in one paragraph
You open Sieve, enter an API key from your chosen AI provider, create a label set (a named list of categories), then select a folder of images. Sieve sends each image to the AI, gets a classification back, renames the file to include the date and label, and copies it into a subfolder named after the label. You end up with a clean, organised folder structure and a CSV file summarising every result.
