Automations like: integrate your Codex CLI workflow with OpenClaw, or streamline your team's Gemini CLI tasks.

How it helps

AionUi saves you time and hassle by allowing you to easily customize your assistants and automate repetitive tasks across multiple CLI tools.

Real use case example

"A solo developer, Alex, uses AionUi to build a customized coworker for their Gemini CLI that automatically logs issues and assigns them to team members. Alex configures the coworker in 5 minutes using AionUi's intuitive interface. As a result, their team works more efficiently and effectively."

Use AionUi when you're new to creating customized coworkers and automation for CLI tools.

If you're senior
