AI agents thatreview and research at scale
Deploy AI personas that validate hundreds of user journeys concurrently, conduct deep research, and deliver actionable insights directly to Linear and GitHub.
AI personas thatthink like real users
Create AI agents with distinct personas, backgrounds, and motivations. Each agent navigates your product like a real user, uncovering insights that traditional testing misses—from accessibility issues to workflow friction.
Design reviewsat massive scale
Run hundreds of concurrent user journeys to validate every interaction, edge case, and user flow. Each agent documents their experience with screenshots, reasoning, and verifiable evidence—revealing issues before your users find them.
Insights deliveredwhere you work
Agent findings flow directly into Linear issues and GitHub pull requests. No context switching, no manual transcription. Your team gets actionable insights with full evidence trails right in their workflow.
Research thatgoes deep
AI agents conduct comprehensive research with the patience and thoroughness of a dedicated researcher. They explore edge cases, test accessibility, validate workflows, and synthesize findings into clear, actionable reports.
Cheaper thana complaint
Traditional user research is expensive and slow. By the time you get insights, you've already launched. Stunt Double gives you predictive insights that prevent costly mistakes—before you build.
Calculate Your Research Costs
Assumptions:
- • Traditional: $100 per participant recruitment
- • Traditional: Analysis time = 50% of interview time
- • Traditional: 15 min per participant for reporting
- • Traditional: 2 participants recruited per day + 7 day buffer
- • Stunt Double: $99/month subscription
- • Stunt Double: 30 min setup + 15 min per session review
This calculator provides illustrative estimates only. Actual costs may vary based on your specific research needs and methodology.

Deep User Research
AI-powered qualitative insights
Create AI personas that explore your product with the curiosity and thoroughness of real users. They test workflows, document friction points, validate assumptions, and surface insights that traditional analytics miss—all without recruiting or scheduling.
PR Review Automation
Validate changes before merge
Connect agents to GitHub pull requests to automatically validate UI changes, test user flows, and verify accessibility. Agents comment directly on PRs with evidence-backed findings, catching regressions before they ship.
Linear Integration
Issue-driven testing workflows
Trigger agent validation directly from Linear issues. Agents test the described user journey, document their findings with screenshots and reasoning, then update the issue with results—creating a seamless design review workflow.
