Messaging/Prompts Hourly Limits

I am mainly using ChatGPT for content generation and re-writing. I am interested in the Plus version and ready to pay, but for some reasons, I am seeing Instagram Reels and YouTube Videos and Shorts, Quora Questions, that say, that there is an hourly sort of limit on the number is messages/prompts. There is no such mention on your website or in any communication.

You may want to add it to clarify it for potential customers and clear the air. And lastly, I want to know if there is any limit or not. And if yes, what is the limit.
