FAQ

FAQs About Hiring for Scale Studio

Common questions about finding and managing annotators for your Scale Studio projects.

Once you've made your hires through OpenTrain, invite them to your Scale Studio team using the Teams settings or API. Add their email addresses and assign them the "labeler" role. They'll receive an invitation and can start working on assigned tasks right away.

We have specialists for all the data types Scale Studio supports, including image annotation, video annotation, LiDAR segmentation, document transcription, text, and audio. Whether you need bounding boxes, polygons, 3D cuboids, or structured data extraction, just specify your requirements when you post your job.

Yes. Many of our annotators have experience working in Scale Studio, including using annotation tools, completing training courses, following ontologies, and working within review layers. Note your requirements in your job post and we'll match you with experienced candidates.

No. Your datasets and annotations stay in your Scale Studio account. OpenTrain handles hiring, communication, and payments only. We never access your Scale Studio 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 Scale Studio account for large or ongoing annotation projects.
