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.
