About AIUtilBox

We build free, simple tools that help you create content and get more out of AI.

Our mission

AI can save hours of work, but writing the right prompt or the perfect caption still takes time. AIUtilBox gives you small, focused tools that do one job well, for free.

What we offer

Social media tools for Instagram captions and bios, LinkedIn headlines and posts, hashtags and YouTube titles.
AI prompt tools that help you write better prompts for ChatGPT, Claude, Gemini and Midjourney.
An AI tools directory to help you find the right AI app for any task.

How our tools work

Our tools run in your web browser using proven writing formulas and templates. That keeps them fast, free and private, since your text is not uploaded to our servers.
