Deltix

Deltix is an AI agent that tests mobile apps the way a real user would. A tester or developer writes a task in plain English, such as signing up and sending a first message, and the agent attempts it on an iOS Simulator running on the user's Mac, then reports whether a real user could complete it. Each step and screenshot is recorded so the team can see where the agent hesitated or got stuck. The product has three modes built on the same agent. A Task is a single exploratory attempt for a new flow. A Playbook turns a successful run into a deterministic regression check that can be replayed from the dashboard against each new build, without maintaining XCUITest assertions. An Experiment runs the same task against two builds of an app side by side to compare which one users can complete. Setup involves creating an account, installing a small native Mac Agent, and attaching it to a running simulator. It suits mobile developers, designers and QA teams who want usability and regression checks without scheduling research sessions. The vendor states that source code, builds and signing identities stay on the user's Mac, while run screenshots and records are stored in the account and can be deleted at any time. Users may bring their own model key to route inference away from the vendor's bill. Deltix is in open beta, supports iOS today, and is free to start with no credit card. Paid plan prices are not published. The tool is a software testing product rather than a writing tool.
