Vibe Check: Measure and compare your Product Journeys

Vibe Check is a practical AI tool that benchmarks user experience on any website. You give it a URL and a task — say, "find the checkout button" — and it runs an AI simulation that tries to complete that task, reporting back on how easy or frustrating the journey was. It measures things like time-on-task, miss-clicks, path taken, and drop-off points. Think of it as a quick, automated usability test you can run in minutes without recruiting human participants.

Under the hood, Vibe Check uses AI models (with a zero-retention agreement with Anthropic's Claude) to simulate how a user might interact with a page. The AI leaves a "thinking" audit trail so you can see why it made each click. It also generates heat maps of where AI and future human testers tend to click or pause. The tool integrates with Figma via a plugin, making it easy to test prototypes early in the design process. Pricing starts with a free tier (5 simulations) and scales up based on simulation volume.

This tool is most useful for product designers and product managers who want to catch friction points before investing in full human user testing. It's great for quick comparative checks — testing a new design against an old one, or your site against a competitor's. Vibe Check won't replace real user studies, but it's a fast, repeatable way to get early quantitative signals and prioritize what to fix first.
