I see people being deceived by this again and again: ChatGPT can NOT read content from URLs that you give it, but it will pretend that it can (and can be incredibly convincing when it does that)
Constantly debunking this feels like a Sisyphean task, but it's really important to spread this message any time you see anyone falling into this (very understandable) trap
