Multimodal Data Annotation Platform

Annotate image, video, audio, text, documents, DICOM and volumetric medical data, whole-slide pathology, and geospatial imagery in one platform. Unitlab AI keeps multimodal training data consistent with shared ontologies, AI assistance, and governed quality control.

Integrated Workflows

Build custom workflows that connect models, annotation, review, and quality assurance in one continuous loop. Reduce manual handoffs and keep datasets moving from data intake through annotation and approval.

Video & Audio Sync

Align video frames and audio timelines in one view. Label speakers, events, and objects with temporal accuracy while reducing manual work across long-form recordings.

Text & Image Context Sync

Connect visual data with text and metadata in a shared context. Annotate images, documents, and extracted text together to preserve meaning across modalities.

AI-Powered Multimodality

Annotate image, video, audio, and text together to train models that understand richer, real-world data.

Bring your Model

Integrate your own AI models into the annotation workflow. Use model-assisted labeling to pre-annotate data, improve accuracy, and iterate faster on real-world datasets.

Frequently Asked Questions

Is Unitlab AI a free data annotation tool?

Yes. You can use Unitlab AI for free, no credit card required. The free plan is great for getting started and testing workflows. If you need more scale, advanced features, or custom setups, paid plans are available.

Can I change my plan after creating an account?

Yep. Start free and upgrade anytime. Most teams begin on the free plan and move to a paid plan once their datasets or team size grow.

What types of data can I annotate with Unitlab AI?

Unitlab AI supports image, video, audio, text, document, DICOM and volumetric medical imaging, whole-slide pathology, and geospatial annotation. Teams can curate, annotate, review, version, and manage these data types in one governed platform.

Does Unitlab support AI-assisted and auto-annotation?

Yes. Unitlab AI includes built-in AI models to speed up annotation with auto-labeling, tracking, and segmentation. You can review, edit, and validate everything to keep quality high.

Can I use my own AI models with Unitlab AI?

Absolutely. Unitlab supports Bring Your Own Model (BYO) workflows. You can plug in your own models, combine them with Unitlab’s built-in models, and run multiple models in a single annotation workflow.

How does Unitlab AI platform pricing work?

Platform pricing depends on the plan, team size, storage, and workflow requirements. Start on the free plan, then upgrade as dataset volume, collaboration, security, or deployment needs grow.

Who has access to my data?

You do. With on-premises deployments, all data stays inside your own infrastructure and Unitlab has no access to it.
 If you use Unitlab’s hosted platform, your data is encrypted and isolated, and is not visible to Unitlab staff. Access is strictly controlled and limited to your team based on roles and permissions.

Does Unitlab support team collaboration and review workflows?

It does. Unitlab is built for teams, with support for multiple annotators, reviewers, approval steps, and full annotation history so nothing gets lost.

Can Unitlab handle large datasets and production workloads?

Yes. Unitlab is designed to scale, from small experiments to production-level data annotation. Teams use it to manage large datasets, complex workflows, and long-running annotation projects.
