We almost shipped the wrong design. 🤦‍♂️

~2x faster conversion while the others designs all floundered. That was the result of simulations doing the talking while building password only access for Vibe Check instead of arguing in circles.

"Failing" designs cost the collective time of every user and then again by a Product team working on needless iterations. We ve baked this simulation first mindset into our new tool, Vibe Check. We launch on Product Hunt next week! Support us and ensure actual conversion on your next product designs.

Vibe Check is officially live, we'll help discover your time to value

To promote our Product Hunt launch of Vibe Check today, we are offering free evaluations. We are looking for Vibe Coded prototypes to promote and discover their time to value. To take part, just share the link and what journey you'd like to test and we'll provide a link and report on your UX performance analytics.

Here's an example for Vibe Tickets

A thinking simulation like this and a UX performance report like this.

Learn by doing, learn by seeing. Now launching Tues March 31st

"Enter any web address! Test any prompt!" PMs and designers more often than not just Freeze when confronted with an empty input box. This has gave us pause. We intended to launch VibeCheck today but we are delaying to build clickable demos showing how teams can compare their results with competitors.
Now that building is so fast, validation is the new bottleneck. Creating your interface and variants may take seconds, but the main challenge remains verifying what your audience can achieve.
Adding demos and canned prompts, helped designers find their rhythm on our Figma plugin. We need to do the same on the web interface to help PMs and Founders 'learn by doing', but also 'learn by seeing' on web URLs.
Since we can only launch once a quarter on PH, we've pushed our Vibe Check launch back to March 31st, launching with demos
