Thank again for the feedback. I went with your idea of using images of cute robots and it indeed feels better than the realistic images. I'm launching the updated version on ProductHunt today: https://www.producthunt.com/posts/teamsmart-ai
Good idea. Btw if you install the extension you will see that I had already replaced the human pictures with pictures on AI generated images. They are still faces, but you can clearly see that they are not real people.
