what can ChatGPT actually do?
What can ChatGPT actually do? It can draft, summarize, and brainstorm from the words you give it. It cannot check a fact it has not seen, open your files unless you paste them, or remember last week on its own.
It’s genuinely good at rewriting, summarizing, and drafting from something you already gave it — a document, a list of facts, a rough idea. It’s genuinely unreliable at anything that needs looking something up right now, exact arithmetic at scale, or certainty rather than fluency. Most disappointment comes from asking for the second kind of task and expecting the first kind of reliability.
Not what it claims. What it does when you hand it the real thing.
