Hi @abredi your project looks amazing!
I love all the images you chose and the functionality is really cool, but it has some details that you can easily fix.
Letters with a white color disappear when the user uploads a white image, to fix this issue you can add a black background with some 40% transparency.
Also, all users can edit each article, you can fix it that in order to only the owner of the article have the permission to edit it.
Paperclip is deprecated instead you can use Active Storage
