Multimodal Data Annotation Platform

Annotate image, video, audio, text, and DICOM data in a single platform. Unitlab helps AI teams create high-quality multimodal training data faster, with consistent workflows and built-in 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 labeling to approval without delays.
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.

High-Speed, High-Quality Data Annotation for AI Teams
Unitlab helps AI teams label data faster without sacrificing quality. AI-assisted workflows speed up image, video, audio, and text annotation while keeping datasets production-ready.
Faster annotation across all data types
AI-assisted labeling with human oversight
Consistent accuracy at scale

Dataset Management

Manage and organize multimodal datasets in one place. Version, search, and inspect image, video, audio, text, and DICOM data while maintaining consistency and quality across annotation workflows.

Dataset Versions
Create and manage dataset versions as your data evolves. Track changes, assign tasks, and collaborate across teams while keeping every version auditable and production-ready.
Semantic Search
Search and explore large datasets using semantic understanding instead of manual filters. Quickly find relevant samples across image, video, audio, and text data.
Embedding View
Understand your data at a deeper level by visualizing embeddings across datasets. Identify outliers, spot labeling issues, and improve data quality before training.

Frequently Answered Questions

Is Unitlab a free data annotation tool?

Yes. You can use Unitlab 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?

Unitlab supports multimodal data annotation, including image, video, audio, text, and DICOM. You can manage and annotate different data types in one platform using the same workflows.

Does Unitlab support AI-assisted and auto-annotation?

Yes. Unitlab 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?

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 pricing for data labeling services work?

Pricing depends on the type of annotation, dataset size, number of classes, and complexity. Labeling services start from $0.02 per image, with custom pricing available for multimodal and large-scale projects.

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.
