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.

Basically, they are all automated chatbots connected to ChatGPT, interacting in the community to gain experience or roles in order to receive airdrops. Personally, I feel this is also the biggest use case for communities currently.

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