Today, most people still think market research =
• Paying consultants
• Sending surveys
• Waiting weeks for analysis
But LLMs can now simulate entire target audiences and synthesize answers instantly.

Prompt to generate personas:
“You are a senior market researcher and customer insights strategist trained in persona development, behavioral segmentation, and product marketing.
I want you to create 3 distinct and realistic customer personas based on the following product or business: [Insert product / industry].
For each persona, include the following sections:
– Name, age, job title, and background
– Primary goals and motivations related to the product
– Key frustrations or pain points
– Decision-making process (emotional vs rational, time, influencers)
– Buying objections or hesitations
– Preferred communication channels
– Real quotes they might say during a user interview
Use a neutral, research-style tone and structure your output clearly under each persona. Avoid assumptions — make personas feel grounded and realistic.”
You’ll get founder-ready personas in 10 seconds.

Want survey insights?
Prompt:
“You are an advanced user behavior simulation engine with access to millions of real survey response patterns across industries.
I want you to simulate 50 unique customer responses to the following open-ended question:
‘What’s your biggest frustration when it comes to [insert problem]?’
Assume the respondents are a diverse group of target users from [insert audience e.g., early-stage SaaS founders, Gen Z fitness enthusiasts, DTC ecommerce buyers, etc.].
For each response, vary the tone, writing style, and detail level — just like real survey responses. Some should be short and blunt. Others long and reflective.
After the 50 responses, summarize the top 5 recurring themes or insights and cluster similar responses together.
Label each cluster clearly and explain what it reveals about user pain.”
You get diverse, realistic answers with sentiment and clustering built-in.

Competitive research? Easy.
Prompt:
“You are acting as a competitive intelligence analyst for a fast-growing startup entering a crowded market.
Your goal is to analyze and compare [Your Product Name] vs [Competitor Name] in a research-style format, focusing on opportunities to differentiate.
The report should include:
Feature-by-feature comparison (bulleted)
Pricing model breakdown
Messaging and positioning strategy
Visual branding and tone of voice
Key customer pain points addressed (or not)
Review analysis: top 3 recurring praises + top 3 criticisms for each
Opportunity matrix: where we can differentiate or win
Use a clear and structured tone. If there are gaps in publicly available data, label them as ‘Unknown’ rather than hallucinating. Cite known sources when applicable.”
You’ll get a consulting-level teardown in seconds.
