Describe a task in plain English. Deltix runs it on a simulator and tells you if a real user could complete it.

Privacy by default
Your source and your build stay on your Mac.
The agent runs locally against your simulator. We never access your source, your build, or your signing identities.

While a run is in progress the agent acts on what it sees on screen, like any user would. Those screenshots and the run record sit in your account so you can review and replay. Delete anytime, or bring your own model key to route inference traffic off our bill.
Step
01
Sign up
Free. No credit card. No invite needed. Verify your email and you’re in.
Step
02
Install the Mac Agent
A small native app. Sign in with the account you just created. That’s the only one-time setup.
Step
03
Connect a simulator
Pick any iOS Simulator already running on your Mac. The Agent attaches to it and stays out of your way.
Step
04
Run your first task
Write a task in plain English, like "sign up and send your first message." The agent tries it. You watch it work.
Task
Try once
“Can my user actually do this?”
Ad-hoc. You’re building a new flow and you want to know if it works for a real user, without scheduling a research session. Write the task, watch the agent try, read the screenshot of where it got stuck.
Playbook
Save and replay
“Did we break it?”
Take any successful run and save it as a Playbook. Replay it deterministically on every build, from the dashboard. Pass or fail in seconds.
Experiment
Compare two builds
“Which design wins?”
Run the same task against two builds of your app, side by side. See which one your users can complete and which one breaks, before the design debate goes to A/B testing in production.
Task
“Sign up with email and verify the welcome screen appears.”
