Codex can't fix what it can't see
Codex is OpenAI's coding agent in ChatGPT. Test your iOS app or website by hand and mark a bug with one key or your voice. Codex gets it with the video, the steps and the logs.
No account. Nothing to install in your app or site.
Bugs that cost you an evening
You can't make the bug happen again
Your taps, screens and log lines are saved with the bug.
You can't explain what looks wrong
Codex gets the screen and your own words.
The AI says fixed, the bug remains
You check the fix and approve it.
What Codex gets with each bug

Questions
Do I add code to my app?
No. LastBug records the Debug build you already run in the iOS Simulator. For a website, open its address.
Which plan do I need for Codex?
Your own. LastBug has no AI of its own and no account. It hands the bug to the Codex you already use.
Can Codex see all my recordings?
No. It reads only the tasks you hand to it.
