About Deltix

Write a task in plain English. An AI agent runs it on a simulator on your Mac and tells you if a real user could complete it. Save the successful run as a regression check you can replay later. We never access your source, your build, or your signing identities. Those screenshots and the run record sit in your account so you can review and replay. Everything in Deltix is built on a single thing: an AI agent attempting a user task.
