Insights appear in your daily tools, like Slack, Claude, Cursor, Excel powered by our lightweight MCP server and ready for CI/CD
What Our Customers Say
Join hundreds of companies already using UserTrace to optimize their AI experiences
"At Grammarly, precision and user trust are everything. With UserTrace simulations, we were able to test AI suggestions across realistic multi-turn writing scenarios before rollout. It helped us surface subtle breakdowns and refine responses, giving us confidence in quality before users ever saw it."
Varsha Lalwani
Sr. Product Manager at Grammarly
"Adaface's success relies on creating seamless, high-stakes candidate interactions. UserTrace allowed us to simulate diverse candidate journeys with our interview bots, revealing where conversations broke down. That feedback directly shaped improvements and led to higher candidate satisfaction."
Deepti Chopra
Co-founder at Adaface
"Virtual Internship connects students worldwide with real companies, and every interaction matters. UserTrace simulations helped us stress-test our onboarding AI across different student personas, uncovering friction points we would have missed with manual testing. Fixing them upfront dramatically improved conversion rates."
