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.
