If you really don't understand AI Agents, you can check out the Discord of major projects that haven't issued tokens, the more top-tier the better.

Most of them are automated chatbots connected to ChatGPT, used to gain community experience or roles in order to receive airdrops. Personally, I feel that this is currently the biggest use case in the community.

On Twitter, there are also quite a few automatic replies and creations, but unfortunately, they are too easily banned, and the cost is much higher than on Discord.
