Platform overview

From raw data to
production datasets

01 / Upload

Ingest your data

Drag-and-drop or connect via S3, GCS, or Azure Blob. Supports images, video, LIDAR, and text. Handles millions of files without friction.

02 / Annotate

Label with precision

Professional annotation studio with AI pre-labeling, bounding boxes, polygons, semantic segmentation, NER, and sentiment. Reduce manual effort by 70%.

03 / Export

Export & train

Download in COCO JSON, YOLO, Pascal VOC, TFRecord, or custom schemas. Direct pipeline integration with HuggingFace, Weights & Biases, and major MLOps tools.

Annotation studio

Every label type
your model needs

A unified workspace built for professional annotators and ML engineers — not one compromised for both.

Bounding Box & Polygon
Draw precise bounding boxes with sub-pixel accuracy. Polygon and freehand tools for irregular shapes. AI-assisted snapping reduces click count by 60%.
Semantic Segmentation
Pixel-perfect segmentation masks with smart brush tools and SAM integration. Export as binary masks, RLE encoding, or COCO polygon format.
Video Frame Annotation
Frame-by-frame annotation with object tracking interpolation. Label key frames and let the system propagate annotations through sequences automatically.
NER & Sentiment
Named entity recognition, classification, and sentiment tagging for LLM training data. Span-level and document-level label support with custom taxonomies.
QA & Review Workflows
Multi-tier review queues with consensus scoring and inter-annotator agreement metrics. Catch systematic errors before they reach your training pipeline.

What teams say

"We cut our annotation pipeline from three weeks to four days. The AI pre-labeling isn't just a gimmick — our model accuracy improved because the labels are genuinely cleaner."

SK
Sasha K.
ML Lead · Autonomy Labs

"We replaced a $180k/year contract with LabelSets. Same output quality, fraction of the cost, and the export formats drop directly into our PyTorch training loop."

MR
Marco R.
CTO · RoboSense

"Medical imaging has unique requirements. LabelSets gave us HIPAA compliance, polygon segmentation, and multi-annotator consensus out of the box. Nothing else came close."
