Is there a place where I can read real use cases / actual deployments of AI Agents?

The internet is flooded with examples similar to below but these in my head are not true AI Agents right?

1. If email arrives with pdf, check pdf for invoice information and put it in a google sheet is not a AI Agent? Its a workflow that now has llm call as a node 2. Check my google search console and suggest ideas for SEO - This again is a cron job (run every xhrs), collate information and feed it into a llm to generate ideas. This is a workflow as well. 3. personal assistants - I ask for information and llm figures out which tool to call and gets it and writes to a database

perhaps coding agents which do some stuff autonoumously when prompted is a good example. Is there a compilation of real use case anywhere online?
