We tested 7 UK government ads on 36 synthetic personas
Seven UK government ads on teaching, pensions and Stoptober, each watched by 12 synthetic personas. Watch the ads, see the scores and read what they said.
- Get Into Teaching: all 12 personas preferred the ad that follows a pupil through school. It scored 62 out of 100 against 37.
- Workplace pensions: a tie at 57 each. One ad makes the better case, the other gives the clearer next step.

Research and evaluation,
without the wait
You need to understand how people will react — to your content, your product, your policy, your idea. But recruiting real participants takes weeks and costs thousands. So most teams guess, or skip research entirely.
Chorus gives you a panel of synthetic personas — detailed individuals built from real demographic, psychographic, and cultural data — that can evaluate your content or answer your research questions. You get structured, diverse perspectives in minutes, not weeks.
- Speed: Results in minutes, not weeks
- Diversity: Evaluate across audience segments in minutes
- Honesty: Direct audience signal without groupthink
- Cost: Fraction of traditional research
Sample Audience Readout
Young Professionals, 25–34
Signal: Headline resonates, but CTA feels too aggressive
First-Time Investors, 30–40
Signal: Risk disclosure language unclear. Missed key terms.
"Technical audiences find it clear. Non-experts find it confusing."
We test the method in the open
We replicate published research and match our creative reads against independent third-party benchmarks — publishing what we agree on, what we miss, and why.
Replicating a Peer-Reviewed Food Study: A Focus Group Recovered All 10 Phase 2 Sub-Themes
We re-ran Kumar, Kulkarni & Rathi (2022, Frontiers in Nutrition) on our platform. A follow-up focus group with 16 synthetic personas recovered all 10 Phase 2 sub-themes in a deductive comparison — plus 4 additional frames, including gendered food labor and efficiency-vs-meaning. An earlier 22-person coding pass recovered 8 fully, 1 in adjacent form, and missed 1.
