What Datasaur is
Datasaur is a data-labeling platform for teams that upload material, apply labels, and collaborate on annotation work. Its Data Studio handles spans, text or row classification, document classification, OCR, bounding boxes, audio, and conversations.

A catalog of more than 200 base models supports Amazon SageMaker JumpStart, Amazon Bedrock, Azure OpenAI, OpenAI, and Google Vertex AI.
