Give an unlimited free version with less features than pro

Make a free version unlimited with less features that allows people to see if they like it and have the pro be so much better to drive sales. If you have a free version people would be on the app more than just a brief time the more they are on the app the more chance they will want to subscribe to the pro. What happens is the limited free version doesnt make someone want to upgrade it makes them want to go to another AI. Some food for thought
