AI Annotation Services

High-quality AI models rely on accurately labeled datasets, and Nezda Global’s AI annotation services provide scalable, human-led solutions for companies building intelligent systems across industries. From image annotation using bounding boxes, polygons, and semantic segmentation to text annotation for entity recognition, sentiment analysis, and prompt scoring, our multilingual teams handle complex, multi-modal datasets efficiently. Audio annotation for speaker identification, intent detection, and transcription, as well as specialized medical and finance dataset annotation, ensures domain-specific quality for high-stakes applications. By leveraging human-in-the-loop AI annotation, our process integrates multi-stage QA, hallucination flagging, and RLHF scoring to minimize bias and maintain data integrity.

Tool-agnostic annotation services

Nezda Global’s flexible delivery supports direct tool access, API-based uploads, batch QA, and integration with platforms like Labelbox, SuperAnnotate, Diffgram, CVAT, and LightTag, enabling seamless adoption by AI teams. Our secure workflow, including NDA-protected staff, VPN-only access, and role-based permissions, guarantees data security for sensitive datasets. With multilingual annotation services covering English, Tagalog, Hindi, Arabic, German, and Spanish, clients can scale AI models across markets and languages. Enterprises and startups alike benefit from reduced costs, faster deployment, and improved dataset quality compared to in-house labeling teams. Partnering with Nezda Global for AI annotation ensures precise, compliant, and scalable datasets that accelerate model training, reduce errors, and enhance AI performance, empowering businesses to deploy smarter and more reliable AI solutions globally.

Your Strategic Outsourcing Partner

AI teams are under pressure to:

• Build models with better precision
• Label multi-modal datasets at scale
• Control QA and avoid hallucinations
• Ensure annotation security and bias audits

The problem?

In-house labeling is slow, costly, and difficult to scale across markets and languages.
