Does Labelbox only sell labeling services?

Labelbox is primarily a training data platform that offers the following features:

  • A user-friendly, customizable platform for labeling images, video, text, and geospatial data.

  • Data management tools that allow you to search and filter across all of your data in Labelbox to efficiently select data for labeling.

  • A way to import annotations to Labelbox via our Model-assisted labeling (MAL) workflow.

  • Extensive team collaboration & QA tools.

  • Dashboards to monitor and manage team performance.

  • A labeling workforce that you can integrate into your plan.

How do I set up a labeling project?

Once you have created a Labelbox account, see Project setup. To learn how to set up a project programmatically see this Python tutorial.

What kind of data can I label with Labelbox?

With our out-of-the-box labeling application, you can label the following:

  • Images

  • Videos

  • Text

  • Geospatial data (tiled imagery)

Where can I find the Custom Editor SDK?

If you find that the out-of-the-box Editor does not have the functionality you need, you can build your own custom labeling interface with the Custom Editor SDK.

Billing & pricing

How much does Labelbox cost?

For organizations building expert artificial intelligence systems, we offer Pro & Enterprise licenses. For smaller projects, we offer a Developer license which is free for evaluation, individuals, and small projects with a limit of 2500 labels per year. Check out for more information on the Developer, Pro, and Enterprise license options.

Does Labelbox have a discount for nonprofit organizations or academic users?

If you will be using Labelbox for educational or non-commercial purposes, you may be eligible for an EDU license (see To apply, visit or contact us at [email protected].

How much does the Labelbox Workforce cost?

The cost of a labeling workforce familiar with the Labelbox application is included with all Enterprise contracts. Please visit this page or reach out to [email protected] for more information.

Account management

What happens to my annotations if I migrate from a paid plan to the Developer Tier?

If you migrate from a paid plan to the developer (free) tier, Labelbox will not delete any data from your account. If you have already submitted 10,000 annotations in the past 12 months, you will no longer be able to export labels.

If my account has more than 5 users, will any users be deactivated when I migrate from a paid account to the Developer Tier?

No users will be deactivated, but you will not be able to add additional users.

Labeling workforce

Can I outsource a team to label my data?

If you would like to outsource a workforce to label your data in Labelbox, you have two options:

  • Use our Labelbox workforce when you sign up for a Pro or Enterprise account.

  • Find a third-party workforce and teach them how to use Labelbox.

Can I still use Labelbox if I already have a labeling team?

Yes. Whether your labeling team is outsourced, internal, or both, Labelbox allows your labeling team to annotate data while giving you the tools to measure their label quality and performance. If needed, you have the ability to combine the efforts of your internal team and an outsourced labeling workforce on the same projects.


Does Labelbox provide support?

Labelbox provides support to all Labelbox users. You can find more details in the section Contact Customer Support.

Quality assurance

What is the difference between Consensus and Benchmark?

The Consensus tool allows you to compare the label of one member against the labels of other members to automatically calculate the overall consensus. You can configure the percentage of your dataset in a project that will be selected to be labeled more than once by distinct members. Because this calculation compares a labeler's work to that of other labelers, you can see which labelers are producing labels that tend not to agree with the majority. You can also track the consensus of your labeled dataset against the entire labeling team to ensure high label quality. Poor consensus may also be an indicator of a need to clarify the ontology or classification questions in order to boost the consensus scores.

The Benchmarks tool allows you to set a “gold standard” annotation and compare your labelers' annotations against it. The benchmark tool works by interspersing data to be labeled, for which there is a benchmark label, to each person labeling. The accuracy score for each label is calculated based on its comparison to its respective benchmark.

Will other labelers see the data I am labeling?

If Consensus is turned on and configured for your project, yes. Otherwise, no.

Can I compare model-assisted predictions against human-made labels?

With Labelbox, you can connect your machine learning model and compare your model’s performance against your team of labelers. To learn how to import model predictions to your project, see Model-assisted labeling (MAL).

Does Labelbox have an API or SDK?

Labelbox offers a Python SDK for those who wish to use Labelbox programmatically using Python instead of by writing GraphQL queries and mutations. Visit our Python SDK docs to learn more.

Access to the Labelbox GraphQL API is included in the Pro and Enterprise tiers. Visit our GraphQL API docs to learn more.

How do I create an API key?

API Keys can only be created by organization administrators. To create an API key in the Labelbox UI, go to

Importing & exporting

I already have training data. Can I import it into Labelbox?

Whether you are uploading model-assisted predictions or human-labeled data, you can import your labels via the app or programmatically. To learn more, see our docs for Model-assisted labeling (MAL).

Does Labelbox work with cloud data such as AWS or Google Cloud Storage?

Yes. To learn how to connect your cloud data to Labelbox, see IAM Delegated access (recommended) or Standard hybrid cloud.

Can I import images from my smartphone?

Notably (but not exclusively), photos taken with smartphones have orientation stored as an EXIF tag in the image’s metadata. However, Labelbox does not read this EXIF tag and will render the image in its original, unrotated state. You may upload photos from a smartphone if you use an external image editor to save your image in the correct orientation first.

Which label export formats does Labelbox support?

Your labeled data can be exported in JSON or CSV format, which should allow you to import it into any standard machine learning framework. Labelbox does not offer any native export functionality for COCO or PASCAL VOC.

Does Labelbox work with on-prem data?

Labelbox works with source data hosted on-premises or on a private cloud. For on-prem configurations, the source data is accessed directly from the client computer and is never shared by (or accessible to) Labelbox. Contact us at [email protected] for more information.

What is the maximum upload size for an import?

Labelbox accepts files (image, video, text) up to 256 MB.


Does Labelbox work in all countries?

Yes, unless your network has a restrictive firewall or you have internet connectivity issues. We currently only support the English language on our platform.

Do I need an internet connection to use Labelbox?

You must have an internet connection to use Labelbox. We recommend using Google Chrome to use Labelbox. Due to known compatibility issues, we do not recommend Internet Explorer or Safari.

What if I lose internet connection while I am labeling? Will I lose all of my work?

Your work will be saved as long as you have an internet connection. In the event that you lose your internet connection, a message will appear on your screen notifying you that your internet connection is compromised. If this happens, make sure your connection is restored before you continue working to ensure that your work is saved.

Can I use Labelbox on a mobile device or iPad?

Labelbox is not supported on mobile browsers so using Labelbox on a mobile device or iPad will not work.
