# Menso > AI users run real tasks on your live site and show where they get stuck, with a replay of every step. Menso is an AI usability testing tool. An AI user with a persona runs one task on a live website in a cloud browser; the result is a replay of every step with the AI user's think-aloud and a TRACES score from 0 to 100. Each result is one AI user's run (n=1), a diagnostic for that route, not a substitute for research with real people. ## Pages - [What is AI user testing, and how does Menso run it?](https://menso.io/how-it-works): AI users run real tasks on your live site and show where they get stuck, with a replay of every step. How Menso runs a test, what you get and what it costs. - [What is a TRACES score in AI usability testing?](https://menso.io/traces): TRACES is Menso's 0–100 score for one AI user test: six weighted dimensions, each with a written reason. How it is computed and what it cannot tell you. - [How do I test my signup flow before launch?](https://menso.io/use-cases/signup-flow): Test a signup flow without recruiting users: what to check by hand, what an AI user adds, and two real runs from the Product Hunt board with their limits. - [Which AI usability testing tool fits your team?](https://menso.io/compare/ai-usability-testing-tools): Five kinds of AI usability testing tools, from human panels to agentic QA: who each fits, what each costs, with sources. Menso is one option, not ranked first. - [Product Hunt board](https://menso.io/product-hunt): top launches from Product Hunt's weekly board, each put through the same Menso task, with a TRACES score and a public replay for every run that was scored. - [Pricing](https://menso.io/pricing): plans, credit packs and the credit cost of each test. - [MCP server](https://menso.io/docs/mcp): connect Claude Code, Cursor or Windsurf to Menso with one API key, start a test and read its TRACES score and findings. ## Price Pro: one Fast test ≈ $0.64, one Deep test ≈ $4.83 at $29 / 1,800 credits, plus 10 credits (≈ $0.16) of research when you start from just a URL; Free 100 credits = 2 Fast tests, no card.
