Not sutre what you mwan by prices up? but I would never use AI descriptions, and would never buy from anyone who obviously does. You can spot them a mile away.
AI description is a personal choice. It is still in it's infancy and has some glitches (doesn't seem to pull down item condition for example). Some people think it takes more time to proof-read than it's worth. Busy Sellers like yourself seem to value it more.
