ChatGPT Agent Mode: Automate Large Tasks With a Browser Based AI Agent

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!
