Built for Healthcare
Ango Hub was built from the ground-up for medical professionals who need high quality labels, at scale.

With native support for DICOM, TIFF, Ultrasound, X-Rays, CT Scans and others, as well as a range of 20+ labeling tools, you'll never need to look for another labeling platform again.

Security, Front and Center
Ango AI's entire labeling infrastructure was designed with security in mind, from top to bottom.

Keep your assets in a private bucket, and give Hub only the minimum, temporary authentication needed to display them. And if you need, you can install Ango Hub on-premises in your air-gapped environment, too. In all cases, we cannot see your data.

Our security team is always available to talk at
From One to Thousands of Annotators
Labeling is better together.

Have multiple labelers annotate the same asset, open issues that everyone can see, and upload labeling instructions for all.

Ango Hub works for projects of all sizes, from one to thousands of annotators working on the same dataset.


A platform that adapts to you

Ango Hub is the versatile data annotation platform for projects of any size.

You can check out our page on G2 and SourceForge or SlashDot to see what people had to say about us.

Yes, Ango Hub is built to allow you and your team to perform annotation tasks of any type and size. In the Cloud and On-Prem plans, there are no limits to how many people and assets you can have in your labeling projects.

Yes, we provide a fully-managed data labeling service with an immediately scalable workforce, for projects of any size and difficulty. Check out our Ango Service page for more information.

Yes, our Ango Hub On-Prem package is what you’re looking for. We set up Ango Hub on your server in less than 15 minutes (we use Kubernetes) and you can start labeling immediately with your own team. If you need to scale, upon request, our fully-managed labeling workforce can connect to your server via VPN and help you to label your data.

We support text, audio, image, video, multi-page images, and native PDF annotation.

Check out our Ango Hub page for a complete list of our labeling tools, but shortly, everything your team may need, from the usual points and polygons to more esoteric rotated bounding boxes, tables, and more.

Yes. We have a free plan with which you can try out the platform for yourself. Simply go to and sign up now, no credit card required. Limited to five users, 2000 lifetime assets, and 10k lifetime annotations.

No. Users of our Ango Hub On-Prem plan can tap into Ango Hub’s ever growing fully-managed labeling workforce. If you ever need to scale your team quickly, or if you want to switch to outsourcing your data labeling tasks, contact us and our annotators will connect to your platform via VPN, and become part of your labeling team.

Yes. Built into Ango Hub are consensus and review features helping to make sure the quality of your labels stays high. You can have up to 30 people annotating the same asset: Ango Hub will calculate the consensus between them and tell you whether or not the labels agree. Plus, you can have a reviewer double checking the result.

Users of our Free and Cloud plans have two options: they can import the data to Ango Hub (therefore to our cloud servers) or they can directly annotate data they store on a cloud storage service (e.g. S3, R2, GCP.) In this second case, your data does not get uploaded to our servers and it remains stored in your cloud storage of choice.

Users of our On-Prem package can choose to label data directly from their server, or to import data they are storing on a cloud storage service. In both cases we have no access to the data.
