Thanks for hunting @garrytan 💪!

Hi all, I'm David, the other co-founder of @Snap. We want to make research part of every team's workflow.

Please try it out and let us know what you think!

This actually works, guys! Feels like Playwright MCP in action, but extracting relevant data from every step. Great job, team! 👏

Already got some great feedback. It would be amazing if I could click 'Continue' on the task I assigned. It stopped before completing the full goal, probably because of my mandatory analysis step takes a bit of time and it hit a timeout on your end.


Love how it helps teams validate designs faster without recruiting testers. Great launch!

V grateful that the design space is getting such a valuable addition to the ecosystem. Hopefully this saves companies thousands of wrong directions and gets value to market faster
Congrats to @erictli and the whole Snap team on the launch! This is a really interesting approach — the ability to run instant usability tests with AI personas could be a game changer for validating functionality, user flows, and overall experience before launch. Curious to know — can we define our ICPs so the AI personas align with our target audience profiles? That would make the insights even more precise and actionable.

Finally, someone’s making usability testing actually doable for busy teams! Building AI personas from real user transcripts is such a clever shortcut.... I am wondering if you’ve seen any surprising insights vs. manual tests? Btw Congrats team!!

Well this one sounds really exciting! And brilliant ofc. AI-driven usability testing could save designers days of manual feedback loops.

This could really save time. Just an idea for you: a question template for user interviews would be great to attach to your trial, something that helps uncover real user habits and shape an AI persona that’s genuinely useful in testing. Not all user interviews are equal, unfortunately.

Hey everyone, I’m Eric, co-founder of @Snap. Thanks to @garrytan for hunting 🚀

Before this, I was a designer at companies like Uber and Bread, where I saw firsthand how valuable usability testing is in improving product quality. I also saw how rarely teams have time to do it.

Recruiting participants, scheduling sessions, conducting interviews, and analyzing recordings can take weeks. As a result, most teams only research a small percentage of features (if at all).

Snap lets you run instant usability tests with AI personas built from your real users.

  1. Build a persona in seconds by uploading interview transcripts or describing your target audience

  2. Drop in a prototype link, upload images, paste a website URL, or use our Figma plugin

  3. Your AI personas will test the design like real users, thinking out loud as they decide what to do next

  4. Get results in minutes with transcripts, recordings, and actionable recommendations

We're seeing evidence in academic research that AI users can simulate real user behavior with surprising accuracy. We believe this will help teams make user-centered decisions in the 95% of cases where research wouldn’t have happened before. If AI is making it faster than ever to build, it should also make it faster to learn.

We'd love your thoughts, feedback, or ideas for how you'd like to see us evolve Snap!

P.S. If you prefer to do research with real users, we also have a product for that.
