Birla Opus Paints 30s Ad — Indian Persona Evaluation
10 Indian personas score Birla Opus's airport launch ad. The 16-year warranty hooks attention; the 'Main bhi' crowd undermines belief. Overall 53/100.
- Strong attention capture (16-year warranty hooks every persona within 3 seconds)
- Bandwagon 'Main bhi' execution backfires with analytical and rural viewers
Birla Opus Paints 'Main bhi' — Full Creative-Testing Dashboard
Chorus's 10-persona creative-testing dashboard for Birla Opus's April 2026 'Main bhi' airport ad — emotion arc, per-persona signals, scene heatmap, and timestamped edit suggestions.
- Attention peaks at 0:14–15 (1.0/1.0) on the wide crowd shot. The ad's measured visual climax sits squarely on the proof mechanic the panel found least convincing.
- Three cross-persona convergence beats: warranty claim at 0:03 (0.98 agreement), 'Main bhi' chorus reads theatrical at 0:08 (0.91), Aditya Birla brand reveal restores trust at 0:23 (0.89).
ITC Mangaldeep 'Sixth Sense' — Full Creative-Testing Dashboard
Chorus's 10-persona creative-testing dashboard for ITC Mangaldeep's April 2026 'Sixth Sense' ad — emotion arc, per-persona signals, scene heatmap, and timestamped edit suggestions.
- The 0:54 smell-reveal moment is the single highest-agreement beat across all 10 personas (0.98) — universally read as the strongest emotional payoff.
- Four cross-persona convergence beats: relatable opening lie, smell reveal, dignified CSR cut, brand close — agreement scores 0.76 to 1.00.
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."

Replicating a Peer-Reviewed Food Study: 22 Synthetic Personas Recovered All 11 Themes in Focus Groups
We re-ran Kumar, Kulkarni & Rathi (2022, Frontiers in Nutrition) on our platform with 22 demographically-matched synthetic personas. Our focus-group replication recovered all 11 of the paper's themes — plus 4 additional frames the group format uniquely surfaced, including gendered food labor and efficiency-vs-meaning. Our earlier interview-format pass on the same panel hit 10 of 11.
