FAQ
We train an AI model on real user sessions from your production environment. Our models learn how your users use your app, how they interact with elements, and the typical as well as the edge cases flows they take
Then we connect the model to a browser, gives it a username and password and let it generate tests. Since our model is trained specifically on your software, it executes every edge case and produces automated tests
- Integrate our javascript SDK, which is simply pasting 3 lines of code when your app is mounted.
- Provide us with a seed test user on your production or staging environment, so we can generate the tests on that user
To train the model, we are recording your user sessions in a similar way to solutions like Fullstory or Hotjar. To protect your users' privacy, we hash all inner texts, so we don't store sensitive information. We also provide full privacy controls so you can mask any events from sensitive elements
Our impact on performance is non-existent as we use battle-tested open source tools used by Fortune 500 companies
