LLM (Large Language Model) Annotation Services
LLM annotation is a specialized process where complex datasets are curated, labeled, and aligned to train advanced generative AI models (such as ChatGPT, Gemini, and Claude). As part of our AI data annotation services, our experts structure text data to optimize model performance, accuracy, and domain-specific knowledge.
High-performing LLMs depend on a robust human-in-the-loop (HITL) framework. The InputiX annotation team acts as your human verification layer, helping your AI models understand nuanced language, follow complex instructions, and evaluate reasoning patterns. This directly improves model outputs for Q&A, content summarization, code generation, and RLHF (Reinforcement Learning from Human Feedback).

Special Categories of Annotation

PDF Annotation
PDF is the standard document format across legal, financial, and governmental sectors. We annotate and extract text, embedded metadata, tables, and notes from complex PDF documents to accelerate document digitization and optical character recognition (OCR) workflows.

Website Annotation
Essential for digital safety and content moderation, our team annotates live web pages and dynamic online assets. We classify, tag, and structure site content based on custom criteria—ensuring effective moderation against harmful content, hate speech, and policy violations.

Medical data Annotation
Our specialized annotators precisely label medical imaging and health records, including CT scans, X-rays, and EHR datasets. These highly accurate training datasets empower AI models to assist with clinical diagnostics, treatment planning, and medical research.

Time-series Annotation
Annotating sequential data helps ML models detect anomalies and predict trends. We label time-stamped datasets—including IoT sensor readings, stock market metrics, and ECG outputs—enabling algorithms to pinpoint critical events across temporal sequences.
Video Annotation Capabilities
Video Classification & Tagging
Categorize full video clips or specific frames using predefined tags. Our annotators classify scenes, identify core elements, and help train models to flag policy-violating, harmful, or inappropriate content automatically.
Video Captioning
Transform visual sequences into structured textual descriptions. Video captioning generates detailed contextual summaries, temporal event descriptions, and meta-data tags to train multimodal and video-understanding models.
Video Action Detection
Track, detect, and analyze human movements and complex behaviors across video sequences. Essential for sports analytics, surveillance, and automated safety monitoring to identify continuous activities with temporal precision.


Video Object Detection & Tracking
Detect and monitor moving objects across continuous video frames. Our annotators track trajectory, spatial position, bounding dimensions, and class labels across entire sequences with frame-by-frame precision.
Covering all types of Image Annotation
Image Tagging or Classification
Assigning one or more labels to an entire image. Image classification helps machine learning models to identify the content of an image and categorize it automatically. Imagine tagging or classification has multi-sector applications. In agriculture, classifying or tagging crop images as trained data helps ML algorithms to detect early signs of crop diseases. Like agriculture, we can classify, tag, and train image datasets for a wide range of industry applications.
Object Detection
Identify and localize objects within an image or video using object detection. We apply different techniques like bounding boxes, semantic segmentation, etc, to detect objects within a photo or video frame. Our data annotation experts accurately detect objects’ location and tag them. You don’t need complex ML algorithms to train your datasets. Precisely annotated image and visual data via expert annotators can help you more.
Image captioning
Extract the key content from the images and tag them using captions. Our annotation experts add key texts to images, like descriptions, to caption them. We generate appropriate texts to define the image content using our skills and years of annotation experience.
Polygon Annotation (Instance Segmentation)
Assign a unique label to each object within an image or video frame. Our annotation experts have the right skills and expertise in annotating polygons. Our team typically selects a set of points along with the boundary of the object and then annotates the data. We assign unique labels to each of the annotated objects.
Semantic Segmentation
Train your AI and ML models with segmented images to develop artificial vision. Our semantic segmentation experts classify each pixel of the image using predefined classes. Classifying each pixel of the images is a tough job, which InputiX has gained expertise in. We classify pixels and label them for varied applications such as autonomous driving, fashion, retail, and more.
Panoptic annotation
Combining both the elements from semantic segmentation and instance segmentation, we do panoptic annotation. We understand every complex type of annotation work due to our expertise in other types of annotation work. Besides that, we do roasted box annotation, lane annotation, cuboids, and other types of annotation with passion and accuracy.
