"Very helpful app!"
It's very handy. Right at your fingertips, you can find everything that AI offers these days. The ability to create your own presets is a big plus. I don't have to go to the specific webpage to talk to my AI assistant. I have it under one shortcut on my Mac.

"Time saver masterpiece"
Before I used @KerligAI, I had to switch to my browser, open ChatGPT, paste my question, and then wait for the response. Now I can open @KerligAI via a shortcut. It collects information from my clipboard. I can directly ask questions, and the answers are generated in no time.
