AI users to test your app, catch bugs, and give feedback
Jina's synthetic users act like your real users. They run QA tests, catch bugs you didn't know existed, and give you feedback on how to improve your app. Completely autonomously.
We initially built Jina as an AI QA engineer. The value prop was simple - turn a prompt into a test case.
But as we worked with customers, we discovered something much more powerful. We could have Jina *be* your user.
Take on your user's persona, explore your app like them catch bugs like they would. All in addition to of course a core foundation in writing QA tests from a single prompt with 0 maintenance.
