What’s new with Prolific: 7 ways to elevate your research in 2025

One moment, you’re planning your next study. The next, it’s December, and you’re looking back at how far you've come. 2024 has been filled with progress and innovation, and at Prolific, we’ve been working to make that research journey faster, smoother, and even more impactful.

Some big updates and launches happened this year, including:

• AI Task Builder, a data annotation product that makes it easy to integrate human feedback into your large-scale annotation projects. You can get early access here.
• We’re now listed on the Google Cloud Marketplace, which means you can access our participant pool through your Google Cloud account.
• You can now distribute your studies based on UK or US census data and political affiliation completely free of charge using our quota and representative samples.

Here are seven ways our latest updates will enhance your research in 2025.

1. Find your perfect participants with new tools

Finding the right participants is easier than ever. This year, our global crowd grew to over 200,000 verified participants worldwide. Plus, we've expanded our geographic reach, adding 16 new countries. Here's what's new:

• Free representative and quota samples: Whether it’s census data or political affiliation, distribute your studies with precision—no extra cost. Tap into 300+ screeners and set the percentage of responses you need from each.
• Custom screening: Have very specific criteria for your study that isn't already covered by our +300 screeners? Add your own screening questions directly into your studies. Learn how to use our custom screeners.
• Bring Your Own Participants (BYOP): Invite participants from outside of Prolific to your studies, keeping all your research efforts in one place. Get started now with our guide.
• Estimated recruitment times: We’ve built a way to estimate how long it will take for your study to be filled, before it's even published, helping you better plan and design your research.

2. Collect data faster with enhanced automation

Perfecting your research design, analyzing results, and building a better world with powerful human data takes time and focus. That’s why, on top of providing the human layer to your projects, we strived to make it as smooth as possible:

• Taskflow: Break down large datasets into smaller, manageable tasks for multiple participants to annotate at the same time. Distribute multiple conditions or survey links using multiple URLs within a single Prolific study. Find out more about how to use Taskflow.
• API upgrades: We launched many new API capabilities, like marking studies as complete without needing a completion code, integration-specific features for our customers, and several performance upgrades so you can automate your studies even better with our API.

3. Build stronger connections with participants

Participants make your research possible, so we’ve made it easier to connect with them:

• Participant groups: You can now create and message multiple participant groups suitable for different tasks and send your studies directly to them. Learn how to set up participant groups.
• Multi-submission studies: Choose how many times the same participant can take your studies. Multi-submission studies fill up 18% quicker than standard studies!
• Participant Wellbeing Report: We measured participant wellness and shared our plans to make their experience even better. Check out the full report here.

4. Seamlessly integrate the tools you love

You can use Prolific with the tools you love and trust. Here's how you can continue working with us to scale and streamline your research:

• Prolific Partner Marketplace: Discover new ways to streamline and scale your research through the Prolific Partner Marketplace, featuring over 60 apps and tools, including those for surveys, market research, and AI data collection and annotation. Now equipped with better categorization and use case filters, it’s easier to find the right partner tool for your use case.
• Google Cloud Marketplace: We are now listed on the Google Cloud Marketplace, which lets users sign up to Prolific via their Google Cloud accounts so organizations can streamline procurement processes, accelerate AI development, and enhance research capabilities across teams.

5. Protect your research with enhanced security

We take security and trust seriously—here’s how we leveled up the security of our platform:

• Multi-factor authentication (MFA): Keep your account secure with an upgraded MFA process that provides an extra layer of security to your account.
• LLM detection: Our onboarding process now flags AI misuse alongside 40+ identity and behavioral verifications. Read about our vetting process.
• Content warnings: Add alerts for sensitive content to set clear expectations for participants and meet ethical standards.

6. Accelerate your AI model training and evaluation

High-quality human data can make a big difference in building reliable AI applications, but integrating human feedback can be complex or time-consuming.

That’s why we launched AI Task Builder, a data annotation product by Prolific that removes this friction and lets you run annotation projects at scale. Here’s what you can do with AI Task Builder:

• Launch text annotation projects immediately (support for more data types coming soon)
• Design and deploy tasks, manage taskers, and collect data in one workflow
• Automate data collection through our API or use our visual user interface

7. Access pre-qualified AI taskers and domain experts

In 2025, we’re scaling our AI training and evaluation capabilities with specialized participants who are pre-vetted and qualified to train and evaluate AI models.

• Expanded AI tasker pool: We’ll soon be releasing access to our specialized pool of verified human raters, pre-qualified to train and test AI models. These AI taskers understand your requirements and deliver reliable outputs from day one. Want to be among the first to work with our AI taskers? Join the waitlist here, and we'll let you know when they're available.
• Verified domain experts: We will expand our pool with verified subject matter experts across various fields—combining the power of our global crowd with niche, qualified participants to train and evaluate your models and share their knowledge. Watch this space.

There’s more to look forward to: easier messaging at scale, faster collaboration, simpler workspace management, and many other improvements that will make Prolific even more intuitive to use.
