Do Authors Need a 'Character Relationship Map'?

Hello! I am an aspiring novelist.

A few years ago, while writing, I found it challenging to document and develop critical aspects like the 'Character Relationship Map', 'World Building', and 'Timeline'.

 

So, I decided to create features for them.

The first feature I developed is the 'Character Relationship Map'. Do you think this feature would be beneficial for authors?

I'd like to hear your honest opinion.

Here are the features:

1. Ability to create character faces using AI.

2. Provided character relationship diagram sheet.

3. Easy drawing of relationship diagrams.

4. Capability to create and share character relationship diagrams with friends.
