How our text data collection
process works

Our text data collection workflows are designed to be simple for you and precise for your AI goals. From first contact to final delivery, we take care of the details so your team can focus on model development.

contact and project briefing for image data collection

Tell us what kind of text you need — domains, languages, formats, or sources. Based on this, we create a tailored proposal and custom quote.

We design the collection strategy, prepare detailed contributor guidelines, configure QA workflows, and onboard the right contributors for your project.

A small dataset is collected and reviewed. We calibrate instructions together with you until quality, coverage, and domain fit are fully aligned.

Depending on your needs, text is sourced, transcribed, annotated, or evaluated across global contributors and domains.

Every dataset goes through multiple checks: gold tasks, peer review, automated validation, and expert review to guarantee accuracy.

Final datasets are delivered through encrypted download, API, or secure hosting in the structure and format you prefer.

Need additional languages, domains, or new types of text? We can expand or refresh your dataset to keep your models current.
