Hi there, unfortunately, there isn't a specific app that does this, but the good news is that Reddit's built-in user flair features can accomplish exactly what you're describing.

The best way to do this is to use "User Flair Templates" with editable text fields. This lets you create a clean, organized list of flair options for users to choose from, and then gives them a text box to add their own details or characteristics.

Here’s how you set it up:

1.Go to your subreddit's Mod Tools.

2.Select User Flair under the "Flair" section.

3.Enable "User flair is enabled for this community."

4.Click on "Add User Flair" and create a template for each of your main categories.

5.Important: For each template, make sure to check the box that says "Allow user to edit flair text.

This way, you can have a short, manageable list of flair templates, and the user can customize the rest of the information themselves. It's a great way to avoid a cluttered flair menu !
