Data work matched to the complexity of the task
DataSea combines structured annotation workflows with domain-aware review, so you can use specialist judgment where it matters without paying specialist rates for every step.
Not every task needs the same level of review
General annotation
Trained contributors handle well-defined, repeatable labeling at consistent quality.
Domain-aware annotation
Contributors with relevant background handle tasks that require context or terminology knowledge.
Practitioner review
Working practitioners check and correct annotation where judgment calls are common.
Validation & adjudication
Senior reviewers resolve disagreement and set the standard for the rest of the batch.
Data Formats We Work With
Annotation and preparation across modalities, with the review tier set by task complexity.
Image Annotation

Video Annotation
Frame-by-frame review for action recognition, object tracking, and scene understanding.
Text & Document Classification
Sentiment, entity recognition, categorization, and document parsing tasks.
Audio Transcription
Speech-to-text across languages and domains, reviewed for accuracy.
Multimodal & 3D Data
LiDAR and 3D point cloud annotation for robotics and spatial computing use cases.
Validation & Adjudication
Quality sampling and disagreement resolution to keep large batches consistent.
