## What is ideon?

Ideon is a daily thinking training app for people interested in startups or side projects who want to build the ability to generate profitable ideas.

Every day, all users receive the same theme, including a target customer and situation.
Within a time limit, you think through how the idea would make money and submit your answer.
The goal is not actual sales, but clearly designing a revenue structure.

Submitted ideas are evaluated by AI, which provides a score along with strengths, improvement points, and suggestions to make the idea clearer and more convincing.
This helps you naturally learn how to organize who you sell to, what you offer, and how value is delivered.

You can check daily rankings and compare your results with other users who worked on the same theme, adding a motivating competitive element.

With a paid plan, you can save past ideas and evaluations, review your progress, and use additional constraints for more practical training.
Ideon also offers multiple design themes, allowing you to customize the app’s appearance to match your style.
