Synthetic Audiences based on real people’s posts & comments

Most synthetic audience tools ask you to describe a persona and let AI play around with it. 
YouScan’s Synthetic Audiences work the opposite way. Personas are grounded in real online mentions: what people write about, their preferences, and dislikes.

Prompt-based synthetic audiences

  • Where personas come from

    A text description written by the user

  • Who defines the audience

    The user's assumptions

  • Social media persona details

    Invented to fit the prompt

  • Reactions

    What a model imagines this type of person would say

  • Can you check it?

    No, you can’t

  • Surprises

    Rare: you get back what you put in

YouScan Synthetic Audiences

  • Where personas come from

    Real posts and comments from your Topics in YouScan

  • Who defines the audience

    Actual online conversations, filtered by period, language, source, etc.

  • Social media persona details

    Share of audience, mentions, demographics, sources, and countries

  • Reactions

    Grounded in how these people reacted to similar things before

  • Can you check it?

    Yes. See the real reactions behind each persona

  • Surprises

    Common: personas you didn't know existed show up in the data

Why we built Synthetic Audiences

Leo Lytvynenko, CEO at YouScan

“Attention is more fragmented than ever, which makes it increasingly important to understand your customers and their opinions. With Synthetic Audiences, YouScan adds a new layer to how you understand your audiences, building on over a decade of analyzing real conversations about brands.



Now, you can model how people react before making your next move. That's valuable because it helps you step out of your own perspective to see things through your customers’ eyes.



Give it a try and let us know what you think!”

Leo Lytvynenko, CEO at YouScan

Get to know your synthetic personas

Build Synthetic Audiences to see who is really behind the conversation before you have any ideas to check.

You can ask:

“Who are the people talking about us this quarter, and how is that different from last quarter?”

“Before we enter a new market, what kinds of consumers are already in the conversation?”

“Who talked about our last campaign message, and how did different groups take it?”

Test marketing creatives before showing them to the world

What are you about to publish: a social media post, an image/video, or both? Do concept and creative testing in minutes, with instant reactions.

You can ask:

“What would people think of our creative explainer once we launch it?”

“Does this video read as funny or as cringe to Gen Z?”

“What will people complain about first when they see this launch post?”

Book demo
Comparing the size of a brand's audience segment with two competitors

Analyze competitors & segment opportunity

Check if a segment is big enough to spend on it and define an audience by interests, even with no brand mentioned.

You can ask:

“How big is the competitor’s audience compared to ours?”

“Which interests does this segment share beyond our category?”

“Which segments are our competitors targeting but we are not?”

Book demo
Checking a survey finding against AI personas built from real social media conversations

Validate or reject a hypothesis

Use social data to support or challenge an assumption from other research tools.

You can ask:

“Our survey says women above 25 care most about physical health. Does that hold up in what the audience says online?”

“Is it true that our core buyers prefer sustainable fashion?”

“What would make the audience reject our assumption about this concept?”
