Quick answer: ChatGPT is very good at drafting, summarizing, rewriting, brainstorming and explaining. It is unreliable on exact facts, citations, recent events (unless it searches), and anything that needs real-world accountability. Use it as a fast assistant, then verify before you rely on it.
What ChatGPT Does Well
- Drafting and rewriting: emails, summaries, outlines and first drafts.
- Explaining: turning complex topics into plain language at the level you ask for.
- Brainstorming: names, angles, options and checklists.
- Transforming content: changing tone, length, format or language.
- Coding help: explaining errors and suggesting fixes.
Where It Struggles
- Hallucinations: it can invent facts, quotes, links and sources that look real.
- Math and counting: it can make arithmetic or counting errors unless it uses a calculator or code tool.
- Recent events: without web search, its knowledge has a cutoff date.
- Niche or local details: opening hours, prices, laws and regulations that vary by place or change often.
- Consistency: it may contradict itself in long conversations.
The Main Risks
- Misinformation: confident, wrong answers can spread if you copy them without checking.
- Privacy: anything you type may be stored or reviewed according to the provider’s policy and your settings.
- Bias: models can reflect biases in training data.
- Over-reliance: skills can fade if you stop thinking for yourself.
- Copyright and originality: check rules for any content you publish.
- Security: never paste passwords, keys or confidential files into tools you have not vetted.
A 6-Step Verification Routine
- Ask for sources, then open them. Do not trust a link until you have seen the page.
- Cross-check key facts in at least one reliable independent source.
- Ask it to flag uncertainty: “Which parts are you least sure about?”
- Recalculate numbers yourself or in a spreadsheet.
- Check dates. Ask what its knowledge cutoff is, or use a search-enabled mode.
- Get a human expert for health, legal, financial or safety decisions.
When Not to Use It Alone
- Medical, legal or tax advice.
- Safety-critical instructions, such as electrical or gas work.
- Decisions about people, such as hiring or discipline. See our guide to AI hiring tools and legal risks.
- Anything published as fact without review.
