Get paid to train the next generation of AI models
After skill screening, contributors are matched to projects that fit their domain, from coding and math to linguistics and medicine.
No minimum hours and fully remote work, so experts can fit tasks around study, research or a primary job.
Typical work includes writing hard prompts, producing grading rubrics, ranking competing answers and reviewing model reasoning.
Contributors are paid for approved work each week, with rewards that scale with the quality of their output.
Pre-built AI API endpoints that return clean JSON
More than 30 endpoints span resume parsing, job matching, invoice extraction, translation, SEO tags, content summarization, sentiment and product description generation.
Test real endpoints in the browser on bundled sample documents and text, and see the same JSON your application would receive.
