How Sieve Works
Source
We capture and aggregate multimodal data across real-world, digital, and simulated environments.
Filter
We score for semantics, rights, artifacts, task quality, and more.
Index
We index billions of videos, images, audio clips, and interaction traces with purpose-built detectors and embeddings.
Annotate
We add dense labels, pairings, temporal alignment, transcripts, action metadata, and human QA at scale.
Deliver
We package training-ready datasets, evaluation sets, and environments for secure delivery.
