Unitlab

Labeling images so a machine learning model can learn from them is the job Unitlab handles. Unitlab is a data annotation platform that uses AI to help teams produce accurate labels and work on them together.

It sits in the AI image recognition and segmentation space, so it suits computer vision projects more than general data work.

Pricing is freemium.

The free plan gives you unlimited workspaces and projects, 3 members, 5K source images and 1K auto-labeling a month.

That is enough to test a small project, though the member and image caps arrive fast.

The Active plan costs $99 a month and raises the limits to 5 members, 10K source images and 10K auto-labeling monthly, and it adds private datasets.

Pro is $195 a month with 10 members and 25K source images and auto-labeling each month, also with private datasets.

Enterprise is priced on request and removes the caps on members, source images and auto-labeling.

If auto-labeling volume drives your costs, compare those monthly numbers against your dataset size before choosing a plan.
