Our summary

CodexQA Jev Browser is a tool for checking if a website works correctly. Normally, an AI assistant looks at a picture of a page to decide where to click. This project speeds up the process by turning the webpage into a multiple-choice menu for the AI.

The software builds a list of every visible button and text box. It then uses Jev, an AI tool that chooses from options rather than writing an answer, to pick the right action. Once a test succeeds, the steps are saved so they can be replayed later without the AI.

This is useful for people who want to automate website checks. It requires a private access code, called an API key, to connect to the AI. The authors report that this method was faster and cheaper in their tests, but the software only interacts with items it can currently see.

Key takeaways

The tool only lets the AI interact with buttons and text boxes that are currently visible.
A task is only marked as finished when the required proof actually appears on the screen.
Successful website tests can be saved and run again later without needing the AI to decide.
