Introducing AI Task Builder: The fastest way to train and evaluate AI

Today marks an exciting milestone as we launch early access to AI Task Builder. Built API-first and powered by the Prolific platform, AI Task Builder helps AI developers and researchers build better AI products faster, programmatically or through our intuitive interface.

Bridging the gap in AI development

Whether you're assessing AI outputs for helpfulness and accuracy, or gathering human preferences to fine-tune task-specific models, high-quality human data can make a big difference in making your AI applications more useful, reliable, and accurate.

Until now, AI teams have grappled with a persistent challenge—juggling separate platforms for data labeling and human feedback. This introduces unnecessary friction into the development cycle. You've likely encountered imperfect tools, wrestled with complex third-party integrations, or relied on managed providers that offer limited transparency and control.

Go from concept to data collection in hours, not weeks

AI Task Builder removes friction with a powerful API that’s integrated directly with our platform. Launch text annotation projects immediately, with support for more data types coming soon.

1. Less logistics, more innovation

Our comprehensive API lets you programmatically create tasks, manage taskers, and collect data at scale. It’s perfect for automating workflows to collect training and evaluation data. And if you prefer a visual interface, you can access the same features via our web app.

2. Faster time-to-data

Tap into Prolific’s 200,000+ participants to find high-quality taskers on demand. And easily spin up or scale down projects as your needs evolve.

3. Unmatched data quality

Access diverse, real people from our carefully curated pool. Find the ideal participants for your AI tasks using 300+ audience filters. And with participant groups, you can work with your best-performing taskers again and again across different projects.

Built for fast-moving AI teams

AI Task Builder is the fastest way to tap into high-quality human data to train and evaluate AI.

You can use it to:

• Collect data for fine-tuning a domain-specific or task-specific AI application
• Test your AI product for accuracy or fact-checking
• Evaluate AI bias across different demographics

Getting started

We’re gradually rolling out early access to AI Task Builder for all Prolific customers. We’re also adding more features, such as support for additional dataset types. But we’d love to hear from you on what we should add next.

If you want to use AI Task Builder but don’t see it on your account, request early access here or reach out to your Prolific contact and we’ll help you set it up.
