How it works
Four steps. AI does the heavy labeling. You keep the final call.
Bring JPG, PNG, WebP, or a ZIP. Keep the batch in one dataset.
Name the classes you need. Give the model a clear vocabulary.
A model drafts bounding boxes across your images.
Adjust any box you need; changes save automatically, then download your dataset.
Label what you need
Need to find cars, potholes, invoice numbers, or something specific to your business? Type the labels you want. LabelSmelter uses them. You are not limited to a built-in list.
If you can describe it clearly, you can ask LabelSmelter to annotate it.
Skip repetitive labeling
Instead of labeling every item by hand, tell LabelSmelter what you need and run it across the whole batch. Then fix any mistakes and export your finished dataset.
