FAQ

FAQs About Hiring for Snorkel AI

Common questions about finding and managing annotators for your Snorkel AI projects.

Once you've made your hires through OpenTrain, add them to your Snorkel AI workspace through Admin Settings > User Management. Assign them the "Annotator" role (or "Reviewer" if they'll manage other annotators). They'll receive access and can start working on assigned batches right away.

We have specialists for all the workflows Snorkel AI supports, including ground truth labeling, LLM evaluation, response ranking, fine-tuning data curation, document classification, information extraction, and NER. Whether you need annotators for text, PDFs, or images, just specify your requirements when you post your job.

Yes. Many of our annotators have experience working in Snorkel AI, including using the Annotation Suite, completing assigned batches, providing feedback via tags and comments, and supporting active learning workflows. Note your requirements in your job post and we'll match you with experienced candidates.

No. Your datasets and annotations stay in your Snorkel AI workspace. OpenTrain handles hiring, communication, and payments only. We never access your Snorkel AI projects or annotation data.

OpenTrain charges a platform fee on top of what you pay your annotators. You set your own rates and pay only for completed work. No subscriptions or minimums.

Managed Service is for teams that need a dedicated annotation workforce without handling recruiting, training, and management themselves. We run end-to-end operations inside your Snorkel AI workspace for large or ongoing annotation projects.
