OUR DATA

ANNOTATION SERVICES
Image Annotation
We label objects, faces, signs, and more in pictures. This helps AI systems understand what they “see” in images. Useful for things like security cameras, medical scans, or self-driving cars.
Text Annotation
We highlight and tag words, phrases, or sentences in documents or messages. This helps AI understand meaning, emotions, or topics—perfect for chatbots, voice apps, and translation tools.
Audio Annotation
We label sounds, voices, or background noise in audio clips. This helps AI learn to recognize speech, music, or alerts. Useful for voice assistants, call centers, and hearing tech.
Video Annotation
We mark objects and actions frame by frame in videos. This helps AI follow movement or understand events. Great for sports tech, smart cameras, or training simulations.
Semantic Annotation
We link words and data with deeper meaning, like tagging “Apple” as a fruit or company. This helps AI systems think more like humans and improve search or recommendations.
Bounding Box Annotation
We draw boxes around objects in images to help AI detect their size and location. This is commonly used in retail, farming, and robotics.
Polygon Annotation
For more complex shapes, we trace exact outlines around objects to help AI recognize them with high precision—great for medical or satellite images.
3D Point Cloud Annotation
We label 3D data from tools like LiDAR to help AI understand spaces in three dimensions. This is useful for self-driving cars, drones, and AR apps.
Keypoint Annotation
We mark important points on objects or people, like eyes, hands, or joints. This helps with tracking body movement, face recognition, or fitness apps.
Sentiment Annotation
We tag emotions or feelings behind text, helping AI understand if a message is happy, sad, or angry. Great for social media tools and customer feedback systems.
