Common questions

What is Ondera?

A verified network of native-speaking professionals for AI training data and evaluation. Doctors, lawyers, engineers, scientists, linguists. We focus on the languages where models are weakest: Arabic and its dialects, Hindi, Urdu, Swahili, Indonesian, and more than 20 others.

How is this different from crowd platforms?

We're not a crowd of 250,000 anonymous workers, and we won't send you 400 resumes to sort through. Every expert here has had their license documents reviewed, their identity matched, and their knowledge tested. And we tag people down to the dialect. Egyptian Arabic and Gulf Arabic are not the same thing, and your model knows it even if your current vendor doesn't.

How fast can you staff a project?

Days, usually. Not months.

Where does the work happen?

In your own tools. Label Studio, Argilla, your internal platform, or a spreadsheet if that's what you use. Your data never touches our systems, and every expert signs an NDA before getting access.

How do you handle quality?

Calibration before real work starts, golden sets during, agreement tracking throughout, and a senior expert reviews a sample of everything before it reaches you.
