Data Annotation Services
In today’s AI-first world, the difference between smart and subpar models comes down to one thing: quality data. At NextWealth, we transform raw information into machine-ready training data using a human-in-the-loop approach—delivering gold-standard annotation across image, video, text, audio, and 3D formats. From autonomous navigation to KYC automation, precision begins with our labels.
What is Data Annotation?
Data annotation, or data labeling, is the process of tagging raw data—like images, text, audio, or video—so machine learning models can understand it. This annotated data serves as the ‘ground truth’ for training AI systems to recognize objects, interpret language, or make decisions. Without accurate annotation, even the most powerful models fail to perform reliably.

Types of Data Annotations We Support
Image Annotation

Video Annotation

Text Annotation

Audio Annotation

3D / LiDAR Annotation

Synthetic Data QA

Applications of Data Annotation Services
Our data annotation services support real-world AI use cases across diverse sectors:
Autonomous Vehicles
Data annotation enables autonomous vehicles to detect objects, pedestrians, traffic signals, and lane boundaries through annotated images, LiDAR point clouds, and in-cabin footage. It supports ADAS features like emergency braking, gesture recognition, and driver monitoring, ensuring safer navigation by training vision systems to interpret complex road environments in real time.
eCommerce & Retail
In eCommerce, annotation powers visual search, recommendation engines, and automated product tagging. Annotated product images help classify items by type, color, texture, and style. This enhances search accuracy, enriches catalogs, and drives better product discovery, enabling customers to find what they need faster in online marketplaces.
Healthcare & Life Sciences
Data annotation supports AI-driven medical diagnostics by labeling X-rays, MRIs, CT scans, and pathology slides. Annotators identify regions of interest like tumors or fractures, enabling precise model training. This assists doctors with early detection, speeds up diagnosis, and enhances the accuracy of computer-aided medical systems and research platforms.
Trust & Safety
Annotation in trust & safety helps AI systems identify policy violations in user-generated content. Use cases include facial recognition, KYC verification, liveness checks, and detecting offensive or fraudulent material. Annotated datasets train models to flag risky behavior, ensuring platforms stay secure, compliant, and user-friendly at scale.
Industrial & Manufacturing
Annotation enables defect detection and visual inspection by labeling surface anomalies, component placement, or process errors in industrial imagery. In manufacturing, annotated datasets power quality control systems and robotics. This reduces downtime, ensures consistency, and supports predictive maintenance through better visual understanding of production environments.
Media, Security & Surveillance
Video annotation helps track individuals, identify unusual behaviors, and recognize objects in security footage. It trains AI to detect intrusions, monitor crowds, and assess risk in real time. Annotated data fuels surveillance systems, smart city infrastructure, and content moderation tools for secure and context-aware media applications..
