Mark the objects, regions, and details your vision model needs to learn. Annotation rules and sample review keep labels consistent across a dataset.
Bounding boxes, polygons, and segmentation
Classification, keypoints, and attributes
Guideline calibration and edge-case review
Video Annotation
Annotate video frames with labels that preserve movement and continuity. Define frame sampling, tracking rules, and event boundaries around your task.
Frame-level objects and attributes
Object tracking across selected frames
Actions, events, and temporal segments
Text Annotation
Organize documents and conversations with a clear text taxonomy. Human review helps resolve ambiguous wording and apply labels consistently.
Entities, intent, sentiment, and topics
Classification and relationship labels
Span rules and adjudication guidance
Audio Annotation
Label speech and non-speech audio with the timing and context your models require. Capture speaker turns, sound events, and uncertain segments clearly.
Speaker and turn labels
Word, phrase, or event timestamps
Sound classes and acoustic attributes
OCR Annotation
Prepare image and document labels that help OCR systems read text and understand layout. Capture text regions alongside their order and structure.
Text transcription and bounding regions
Reading order, tables, and key-value fields
Handwriting and low-quality scan review
3D Annotation
Structure point clouds and 3D scenes with labels suited to perception tasks. Define object classes, box conventions, and review rules for consistent spatial data.
3D cuboids and object classes
Point-cloud segmentation and attributes
Coordinate, occlusion, and consistency checks
Generative AI Prompt and Response Annotation
Label prompts and generated responses against a shared rubric. Capture intent, quality, safety, and response traits so examples can support training and evaluation.
Prompt intent and response attributes
Quality, safety, and policy labels
Comparison judgments and rationale codes
How we work
A clear path from brief to delivery.
Requirements agreed early. Human review throughout.
01
Define labels
Agree on the taxonomy, attributes, edge cases, and export schema.
02
Calibrate a sample
Review a small sample together to align labeling decisions.
03
Annotate & review
Apply the guidelines and resolve uncertain examples during review.
04
Export data
Validate label structure and package files for your pipeline.
