Snorkel AI's Products & Differentiators
Snorkel Flow
Enterprises often lack the resources of large AI developers but still need specialized AI models designed to work with their unique data and meet specific operational requirements. Snorkel Flow revolutionizes enterprise AI development by programmatically addressing the most significant bottleneck: data labeling and curation. Instead of relying on manual, time-intensive processes, Snorkel Flow allows users to label and curate data programmatically using rules, heuristics, and automation. It is 10–100x faster than traditional methods, producing higher-quality datasets in an iterative, adaptable, and auditable way. By shifting data labeling and curation from manual tasks to programmatic workflows, Snorkel Flow enables domain experts—like doctors, researchers, and legal professionals—to focus on meaningful, high-impact work.
