What's New: Authenticity checks out of beta, new specialist participants, and more

This month, we're making it easier to ensure data quality and find the right participants for your data collection.

From authenticity checks coming out of beta, to more global participants from APAC and new participant targeting options, read more to see how the latest updates help you collect high-quality data, faster.

Authenticity checks: Now simpler to set up with clearer results

Authenticity checks are a free tool to detect AI-generated content with 98.7% precision for free-text responses on Qualtrics, Prolific’s AI Task Builder, and Gorilla’s Questionnaire Builder.

Now, setting up and interpreting results is more intuitive:

• Fewer steps and clearer in-app instructions for Qualtrics users. Simply paste your Qualtrics link into Prolific, and the authenticity check setup instructions will automatically appear.
• See exactly which questions have been flagged for low authenticity. Use the “Download demographic data” option on the submissions page.
• Read authenticity flags at a glance. Instead of just using colours to flag high or low authenticity, we now use the full words too, so it’s accessible and inclusive.

Filter participants by test scores and task experience

Need participants with proven expertise? We’ve added new types of screeners that give you more options to target participants skilled or experienced in specific tasks or study types.

• Task skill: Filter by test scores for specific AI tasks (image annotation, fact-checking, comparative reasoning, etc.) or domain expertise assessments
• Task experience: Select participants based on the number of similar tasks they've completed

Both screeners are available in the UI and via the API.

Participant pool expansion: New specialist groups and global growth

Access more diverse participants and find the right fit faster with new specialist groups and expanded geographic coverage:

• Participants skilled in structured writing: We've added 1,400+ participants skilled in structured writing tasks - ideal for training data creation, prompt development, content evaluation, and chain-of-thought annotation. Find them under "AI Taskers" in the platform.
• More language experts: We’ve expanded our pool of language specialists, with verified experts now available in Arabic, Mandarin, Japanese, Korean, and French. You can find them in the Domain Experts section of the platform.
• More global participants: We've added over 1,000 participants from India, Egypt, Indonesia, Japan, Korea, Malaysia, the Philippines, and Vietnam, accessible via demographic filters.

Smarter speeding detection

We've improved our speeding detection algorithms to better identify rushed submissions while ensuring legitimate fast submissions aren't unfairly penalized. We've also added protections to prevent participants from repeatedly submitting low-quality, rushed responses. Read more about exceptionally fast submissions here.

AI Task Builder: Better interface for complex text annotation

You can now collect higher-quality data on tasks involving long transcripts, detailed articles, or multi-turn conversations. Participants can expand text datapoints in the AI Task Builder into full-screen for easier reading, with Markdown formatting preserved for structured content like headers, lists, and code blocks.

The result: more accurate, thorough annotations on complex tasks.

User experience improvements

We've made Prolific more accessible with enhanced screen reader support, improved keyboard navigation, and better color contrast throughout the platform - making it easier for all researchers to manage their studies. Read our approach here.

You can also now search for your participant groups - especially useful when working with multiple groups. And project names now support up to 120 characters.
