It tackles one of the annoying parts of mobile QA, turning test cases into something that runs reliably on devices.
With CoWork, I can upload the existing test cases then it plans the steps and executes them on a real device and the part that really caught my attention is how it handles changes during execution. If the app has a different label, an unexpected popup, or the flow changes, it doesn't just blindly continue. It can replan and bring a human into the loop when a decision actually matters. That feels much more practical than treating AI as something that should always make the final call.
I also like that it's focused heavily on mobile testing, including Android, iOS and Flutter, rather than trying to be an AI tool for every type of testing at once.
