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.
Autonomous AI QA agents that verify your web and mobile app on every pull request
Describe a journey or rule in chat and the agent turns it into durable test cases that survive refactors and redesigns.
Every pull request gets a dynamic exploratory pass with preview environments, failure breakdowns, screenshots, console and network logs.
Agents target real browsers and native iOS and Android apps, so coverage reaches beyond the web front end.
Findings flow into Jira and Linear, and agents can be queried over MCP by other coding agents.
