Difficulty Level

Medium – Creating an effective agent requires defining clear goals and workflows, but ChatGPT provides prompts and templates to simplify the process.

Use Case Example

Imagine you are about to build a new website. Rather than take other people’s opinions on what makes a website look “on trend”, you decide to analyse all the winners from the 2025 Web Awards and produce a report. You ask your intern, Jack, to create the report, but after realising it would take 40 hours of work, Jack quickly adds it to the bottom of his to do! Here’s where ChatGPT Agent mode comes in. With a simple but solid prompt, it will open a small embeded browser window and get to work. Sit back with a coffee and a copy of Jack’s last performance review, as Chatgpt Agent Mode does the rest!

In around 20 minutes, ChatGPT Agent Mode has scanned 1800 winning websites, and produce an impressive visual report. Now we can teach this to Jack the intern, so he can drop the excuses and do it next time!
