About Fello AI

I have been struggling with marketing content and AI has saved my life and time. I highly recommend it.

It was great using GPT to write text for our new website will be using this again for social media as well.

This app is amazing.The app allows small businesses equal access and equal opportunity to level up! First day, this app helped my husband tremendously with his business.

Probably best AI chatGPT app I tried in the mac App store. It has everything I need... good job!

Super nice app. Really appreciate simple design. No complicated settings or anything. It just works perfectly.

Really efficient and helpful. Really love the search function because I have a lot of chats every day and sometimes need to go back.
