Codex is great for coding, but also really good for knowledge work. when used properly, codex can take over executing actions correctly and precisely over multiple software products, enabling more focus and less context switching.

I am using OpenAI Codex to help me to write complete automation framework. Like previously I am manually written the test scripts but after using it it enhance me the speed of writing scripts as well as with more efficient manner and just give some images and videos to help to understand the AI agents what are you want ? So its convert into your accordingly demand coding

I use Codex, Claude Code and Cursor daily, but focused on different tasks. Codex as an app is the best overall and has the most reliable models. Would like to see better and easier ways to spin up cloud agents, like Cursor does.
