Bulker is an AI user research platform that turns a single question into qualitative insights from 20 demographic-grounded AI personas in minutes, eliminating recruiting and scheduling.
What is Bulker?
Bulker is a web-based AI tool that performs user research by simulating 20 personas per session, each interviewed in parallel by dedicated AI interviewers. You input a research question (e.g., “What frustrates people about grocery delivery apps?”), and it outputs a synthesized report with key themes, quotes, demographic breakdowns, and fact-checked claims. The platform is built by Bulker and runs entirely in the browser.
Key Features
- 20 AI personas per session — Each persona is constructed from real-world demographic data (age, gender, income, urbanization, education) via largest-remainder allocation and verbalized sampling, ensuring diversity grounded in sources like the World Bank and UN.
- Parallel independent interviews — All 20 personas are interviewed simultaneously by separate AI interviewers; responses are categorized and visualized in interactive charts showing answer distribution and opinion strength.
- Built-in fact-checking — Claims made by personas are validated against linked sources; unverifiable or inaccurate claims are flagged in the report.
- Detailed report — Every session produces a synthesized analysis including key themes, direct persona quotes, demographic patterns, and a fact-check results section.
- Conversational depth — You can ask follow-up questions to all personas at once or open a private chat with any individual persona to explore their perspective.
- Real-time answer classification — Responses are automatically categorized and displayed alongside interactive charts, with no manual tagging or analysis required.
- Zero setup — No recruiting, scheduling, or onboarding; the full research process from question to report takes seconds to minutes.
