Labelbox is an AI data training platform that enables companies to build better machine learning models by offering tools for data labeling, curation, and model evaluation—all in one unified platform. It is designed for teams developing computer vision, natural language processing (NLP), and other AI applications that rely on high-quality training data.
Labelbox helps AI teams efficiently label data, improve dataset quality, and accelerate model training using automated labeling workflows, integrated model feedback, and analytics. Its platform is used by industries like healthcare, automotive, retail, and government to build production-ready AI faster and more cost-effectively.
Features
Data Labeling Interface
Label images, video, text, and geospatial data with precision using intuitive annotation tools—bounding boxes, polygons, segmentation masks, text classification, and more.Automated Labeling with AI Models
Use pre-trained models or your own to automate labeling tasks, reducing human effort and accelerating annotation.Data Curation
Select and prioritize data based on quality, diversity, and model performance impact to improve training datasets.Labeling Workforce Management
Bring your own labeling team or use Labelbox’s managed workforce to scale labeling operations as needed.Integrated Model Diagnostics
Test and validate model performance against labeled data. Identify edge cases and errors to guide retraining.Data Pipelines & Integrations
Integrate with cloud storage (AWS S3, GCP, Azure), data lakes, and ML pipelines to automate data flow.Ontology Management
Define and manage labeling schema (ontologies) across projects and ensure consistency in taxonomy.Real-Time Collaboration Tools
Enable multiple annotators, reviewers, and managers to collaborate within the same platform with version control.Quality Assurance & Review Workflows
Establish quality checks, review queues, and audit trails to ensure label accuracy and consistency.Security and Compliance
Enterprise-grade security features including SSO, RBAC, audit logs, and compliance with HIPAA, SOC 2, and GDPR standards.
How It Works
Labelbox offers an efficient process for managing training data pipelines from annotation to model deployment:
Step 1: Upload and Organize Data
Connect your cloud storage or import files directly into the Labelbox platform. Organize datasets by project or source.
Step 2: Define Ontology and Workflow
Create a labeling schema (ontology) with desired attributes, then configure workflows for labeling, review, and QA.
Step 3: Label Data
Use human labelers or auto-labeling with AI to annotate the data. Combine both methods for optimal efficiency.
Step 4: Review and Quality Check
Use built-in review and QA workflows to validate label quality. Incorporate reviewer feedback directly.
Step 5: Train and Evaluate Model
Train your machine learning models using the labeled data and evaluate performance through Labelbox Model diagnostics.
Step 6: Curate and Optimize
Based on model feedback, select high-impact samples for re-labeling or additional training.

Comparison with Other Tools
Labelbox vs. Scale AI
Scale AI focuses heavily on enterprise labeling services. Labelbox offers more flexible tooling for internal teams and custom labeling operations.
Labelbox vs. SuperAnnotate
Both offer powerful annotation platforms. Labelbox edges ahead with deeper model integration and advanced curation workflows.
Labelbox vs. Amazon SageMaker Ground Truth
SageMaker is tightly integrated with AWS but less flexible for cross-cloud or third-party AI workflows. Labelbox is cloud-agnostic and more user-friendly.
Labelbox vs. CVAT
CVAT is open-source and developer-focused. Labelbox is enterprise-ready with better UI, scalability, and compliance support.
