Data annotation services
High-quality labeled data through expert data annotation for training and optimizing AI models
Comprehensive data annotation solutions
Enterprise-Grade Project Management
Every annotation program is delivered as a managed service, including consulting, technical setup, and execution with dedicated project management. This ensures predictable delivery timelines, consistent quality, and clear communication throughout the engagement.
Specialized Global Workforce
Together with clickworker, LXT provides access to over 7 million contributors and 250K+ domain experts across 150+ countries and 1,000+ language locales. This global reach ensures datasets that are not only large-scale but also culturally and linguistically relevant for your target markets.
Secure, Multi-Layer Quality Assurance
All annotated data passes through multi-step validation, including benchmark tasks and expert reviews. For sensitive projects, work can be carried out in our ISO 27001–certified secure facilities, ensuring both data accuracy and enterprise-grade security.

Secure data annotation services
Some AI initiatives require data to be processed in tightly controlled environments rather than by a distributed crowd. For these projects, LXT offers secure data annotation within five secure facilities worldwide. Here, trained specialists handle sensitive datasets under strict access controls, supported by SOC 2, GDPR, and HIPAA compliance. This ensures that your data remains protected end-to-end while still meeting the highest accuracy standards.

Data annotation for AI
AI models require large volumes of structured, high-quality data to deliver accurate predictions and natural interactions. Since roughly 80% of all data is unstructured, data annotation provides the context that makes it usable for machine learning.
By 2025, global data creation is projected to reach 181 zettabytes, with about 0.4 zettabytes generated every single day (Exploding Topics). At this scale, AI systems need frequent retraining to remain effective and relevant.
LXT helps you maintain a steady pipeline of human-annotated data – regularly refreshed, scalable, and designed for continuous model training.
