After RoastIQOpen when the room still argues about which buyer resists — not another score debate.

Structured buyer interviews

See which buyer still resists before you make the next edit.

Start from a RoastIQ result. Select personas, run structured interviews, and see exactly which buyer objects and why — before the next edit round starts.

Starts from RoastIQ. Run RoastIQ first to get benchmark scores, then open Synthetic Users when the room needs a buyer explanation, not another number.

Run RoastIQ first I have a result — open Synthetic Users

Where it fits

Where Synthetic Users fits the decision loop

Start with RoastIQ. Open Synthetic Users when the first decision still leaves the room arguing about which buyer resists and what should change next.

Start from a saved RoastIQ result

Open Synthetic Users after RoastIQ has narrowed the question. Use the saved result as the anchor when 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 the resistance is message hierarchy, brand timing, or authenticity.
Compare directions without turning the study into 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.

Sample output

What you actually get back

The output includes an executive summary, key themes, verbatim persona responses, and recommended next moves formatted so the room can review it quickly.

Best first use: start with a recent RoastIQ result the team still debates, then compare the study output against the current room narrative.

Q1: What made the ad feel close, but not fully convincing?

The opening mood felt premium, so I stayed with it. The problem was that the product reason arrived after I had already decided the film was more atmosphere than utility.

Once the product finally appeared, it felt like a separate message instead of the payoff of the same story. That made the brand feel polished, but not especially useful.

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 result and report.

Live step rhythm

Watch the study move from RoastIQ handoff to output.

Keep the RoastIQ result attached, choose the buyer lenses, run the same interview, then review raw voice or synthesized output.

Choose the RoastIQ result

Start from the saved report that still needs a buyer-specific explanation.

Confirm the study brief

Keep the focus, decision state, and benchmark frame already attached to the study.

Run the interviews

Use the same structured interview across every selected persona.

Review interviews and report

Move between raw interview turns and the synthesized report depending on what the team needs to see.

FAQ

Questions teams ask before they use it

Synthetic Users is directional signal, not final market proof.

Is this meant to replace real user research?

No, and we are explicit about that. Synthetic Users is the fast directional layer inside SaliencyLab. Use it after RoastIQ gives the first decision, then spend human research budget on the depth only real people can provide.

How is this different from asking ChatGPT?

Synthetic Users uses named buyer profiles, a consistent interview spine, and auditable turns tied to the same creative. A one-off chat response does not give you comparable interviews or a decision-ready synthesis.

Is 6-12 participants enough?

This is a qualitative direction layer, not a statistical-significance tool. Use it for pattern discovery and decision orientation while the team is still editing and comparing routes.

Open Synthetic Users when the score is no longer the debate and the team needs to know which buyer still resists.
