Who Is This Tool Best For?
Teams and organizations looking to streamline their AI training data pipeline.
Pricing
Labelbox has a free tier, rated 4.5 here, with the cost rising as you use it more. A free tier for small projects and paid plans for advanced features and larger workforces, so cost tracks the size of the labelling operation. Details are on the vendor site. The Labelbox site publishes the live figures.
Alternatives
- Scale AI — The managed service: they supply the labour as well as the tooling.
- A spreadsheet and file shares — Free and unmanageable past a handful of annotators.
- An open-source annotation tool — No licence cost and you build the workflow around it.
All of these appear in our AI tools directory.
Use cases
Running annotators at scale
Assigning work, tracking progress and paying by output is what turns labelling from a chore into a process.
Measuring label quality
Review queues and agreement metrics are how you find out whether the instructions are being followed.
Iterating on a dataset
Versioning training data alongside the model is what makes a regression traceable to the data that caused it.
Common questions about Labelbox
What is Labelbox?
A platform for the work around training data: annotation interfaces, workforce management, review queues and versioning, so a labelling operation can be run and measured rather than improvised.
Is Labelbox right for you?
Machine learning teams producing training data continuously, where the tooling matters more than any single labelling job.
Is Labelbox worth paying for?
Entry is free, with paid tiers above it.
How is it different from a labelling service?
It is the tooling rather than the labour. A managed service does the work for you; this is what you use if you have your own annotators and need to manage them.
What to check first
Write the guidelines before the tool
An annotation interface cannot fix ambiguity. Two people must read the instructions the same way.
Plan the QA pass as part of the cost
The review layer is usually the larger share of the work, and skipping it is how a dataset looks finished and is not.
