A concept test is the fastest way to get a directional read from your target market. You give each persona a description of your concept — a product idea, a packaging redesign, a campaign tagline, or a pricing proposal — and each one responds as they genuinely would: in their own voice, with their own concerns and motivations.
Use a concept test when you need to answer questions like:
- Will this new product resonate with our target segment?
- Which of two messaging directions lands better?
- Does this price point feel acceptable, or does it create friction?
- How will consumers react to a reformulation or repackaging?
How it works
When you create a concept test, every persona in your group independently reads your prompt_question. Boses generates a structured response from each persona containing:
| Field | Description |
|---|
| Reaction | A candid response in the persona’s own voice — how they’d actually talk about this with a friend |
| Sentiment | A single label: Positive, Neutral, or Negative |
| Key themes | The 2–4 ideas that stood out most to this persona |
| Notable quote | A presentation-ready line you can pull directly into a deck |
- Sentiment distribution — the breakdown of positive, neutral, and negative responses as percentages
- Top themes — the ideas that surfaced most frequently across all personas
- Strategic recommendations — concrete next steps based on what the group told you
Running a concept test
Create the simulation
Send a POST request to /simulations with simulation_type: "concept_test" and your prompt_question. The simulation starts immediately as a background task.curl -X POST https://api.temujintechnologies.com/api/v1/projects/<PROJECT_ID>/simulations \
-H "Authorization: Bearer <TOKEN>" \
-H "Content-Type: application/json" \
-d '{
"persona_group_id": "<GROUP_ID>",
"simulation_type": "concept_test",
"prompt_question": "We are launching a premium instant noodle range called Mie Emas at 18,000 IDR per pack — roughly 3× the price of Indomie. The packaging uses matte black with gold typography and positions it as a weekday treat for busy professionals. How would you respond to seeing this in your local Alfamart?"

id. Save it as SIM_ID. Poll for completion
Concept tests run in the background. Poll the simulation endpoint until status is "complete". The progress field shows how many personas have responded so far.curl https://api.temujintechnologies.com/api/v1/projects/<PROJECT_ID>/simulations/<SIM_ID> \

Once status is "complete", retrieve per-persona responses and the aggregate report.curl https://api.temujintechnologies.com/api/v1/projects/<PROJECT_ID>/simulations/<SIM_ID>/results \

Reading the aggregate result
The aggregate result synthesises what the whole group told you. Focus on three things:
Sentiment distribution — Is the majority positive, mixed, or divided? A split result (e.g., 45% positive / 40% negative) is as informative as a clear winner: it tells you the concept polarises, which segments are drawn in, and which are not.
Top themes — These are the ideas your personas kept coming back to, regardless of sentiment. A theme like “price sensitivity” appearing in both positive and negative responses tells you the price is front of mind — but not necessarily a dealbreaker.
Recommendations — These are concrete and actionable. They synthesise the themes and sentiment into directional guidance for your next step: refine the concept, run a focus group to probe a specific theme, or proceed with confidence.
Tips
The richer your prompt_question, the richer the persona responses. Include the price point, describe the packaging or visual treatment, name the channel (e.g., “in your local 7-Eleven”), and mention any competitors you are positioning against. Vague prompts produce generic reactions.
After a concept test, run a focus group to let personas discuss the concept with each other. Group dynamics will surface tensions and trade-offs that individual responses miss. Use a briefing to upload a product image, campaign mockup, or PDF deck before creating the simulation. Boses will incorporate the briefing content into every persona’s context.
