Where it fits
Use BuyerLens after RoastIQ narrows the question
RoastIQ makes the first call. This layer exists for the remaining buyer-specific doubt, not for restarting the whole decision.
Start from a saved RoastIQ result
Open BuyerLens after RoastIQ has narrowed the question. The room agrees something is off but still argues about which buyer is resisting.
- Do not start from a blank brief.
- Keep the decision state and benchmark frame attached.
Pressure-test the route
Run the same structured interview across selected buyers to compare hooks, messages, and edit paths without losing the original result.
- See whether resistance is message hierarchy, brand timing, or authenticity.
- Compare directions without open-ended chat.
Use it between edit rounds
Move from one RoastIQ result to a sharper buyer explanation before the next cut or retest.
- Use it when the team needs a reason, not another broad debate.
- Narrow the next edit path before the rerun.
The Science
We obsess over buyer-specific direction
BuyerLens is not a replacement for human research. It is a structured pressure-test that starts from a saved RoastIQ result, compares buyer reactions to the same creative question, and helps the team identify the tension behind the next edit.
How it works
A clear handoff after RoastIQ, not open-ended prompting.
Choose the saved RoastIQ result, confirm the study brief, run the interviews, then switch between interview voice and report.

Study summary
Summer Campaign v3 · 3 buyer lenses

"Proof arrives before the price point is spoken — or the skip is earned."

Carlos
Agency Creative Strategist
"Opens well but stacks three asks before the first pause."
Message overload
Yuki
Authenticity-first buyer
"The product feels secondary to the lifestyle. No personal hook before second half."
Authenticity gapLead with proof before the price claim. All three buyer lenses flag early value prop as the shared edit direction.

How Synthetic Ad Testing Works with BuyerLens
BuyerLens is a synthetic ad testing tool that runs structured buyer interviews against your creative using AI-generated personas. Unlike traditional consumer panels that require recruiting real respondents and waiting days for results, BuyerLens completes a full interview round with 6-12 synthetic participants in under two minutes. Every study starts from a saved RoastIQ result, so the interview stays anchored to the specific creative question the team is debating.
What You Get from a BuyerLens Study
Each BuyerLens study returns three deliverables the team can act on immediately:
- Executive SummaryA structured synthesis of resistance patterns across all buyer lenses. Identifies the shared tension and the edit direction most likely to resolve it.
- Raw Interview VoiceFull interview turns from each synthetic participant. Read the actual buyer language — price resistance, message overload, authenticity gaps — not just a summary score.
- Next MoveA specific, actionable edit recommendation the team can carry into the next creative round. Not a vague suggestion, but a targeted fix tied to the buyer friction.
BuyerLens vs Real Consumer Panels
Real consumer panels remain the gold standard for validated creative research. BuyerLens does not replace them. It fills a different gap: the fast, pre-spend directional layer that helps teams narrow the creative question between edit rounds. Traditional panels cost $2,000-$50,000 per study, take days to weeks, and are typically reserved for final-stage creative validation. BuyerLens runs in minutes for a fraction of the cost, making it practical to test after every edit round rather than once before launch.
When to Use BuyerLens
BuyerLens is most useful when the RoastIQ score has already made the first call (Scale, Sharpen, or Rebuild) but the team still debates which buyer is resisting and why. Open it after the diagnostic, not before. Use it between edit rounds to compare how different buyer segments react to the same creative question. Then allocate human research budget for the depth only real people can provide.
Important Limitations
BuyerLens is scenario simulation, not a real consumer panel. Synthetic participants are AI-generated buyer personas, not real people. Responses are model predictions shaped by persona definitions and creative context. Use the output for pattern discovery and decision orientation, not as final market proof. Sample sizes of 6-12 are qualitative by design; they surface thematic patterns, not statistically significant differences.
