ChatGPT vs Google: When to Use Which

Most people use Google for everything. Then they try ChatGPT and aren't quite sure what it's actually for. Both answer questions, so what's the difference?

The short version: Google is brilliant at finding things. ChatGPT is brilliant at explaining things. Those are different jobs, and once you see the distinction, you start using both much more effectively.

What Google actually does

Google is a search engine. When you type something in, it scans billions of web pages and shows you the ones it thinks are most relevant. The links you see are real pages written by real people (or organisations).

Google doesn't write anything. It finds. That's its whole job.

We tested this on a range of everyday questions and Google excels at a specific type: anything where you want a link to something real, current, or local. "What time does the chemist close?" Google will show you the shop's page, with their actual hours. ChatGPT might guess.

What ChatGPT actually does

ChatGPT is a language model. It doesn't search the internet in real time (unless you're using the paid version with browsing turned on). Instead, it generates a written response based on everything it was trained on.

Think of it as a very well-read friend. They can explain things, help you draft a letter, suggest ideas, and answer follow-up questions. They won't always be right about last week's news, but they're excellent at walking you through a concept step by step.

We've found it genuinely useful for things like: "Can you explain what a fixed-rate mortgage is, in plain English?" Try asking that in Google. You'll get ten articles to click through. Ask ChatGPT and you get a clear paragraph in seconds.

Use Google when...

You want to find something specific on the internet.

• Today's news, weather, or sports results
• A specific website ("HMRC self-assessment login")
• Opening hours, phone numbers, or addresses
• Local businesses ("electricians near me")
• Shopping and price comparisons
• Images, maps, or videos
• Something that happened in the last day or two

For anything time-sensitive or location-based, Google is the right tool. It's reading live, up-to-date pages. ChatGPT is not.

Use ChatGPT when...

You want to understand something, write something, or think something through.

• Explaining a complicated topic in plain language ("What does probate actually mean?")
• Drafting a letter, email, or complaint
• Summarising a long document you paste in
• Getting ideas (gift ideas, holiday suggestions, recipe variations)
• Working through a decision ("I'm thinking of switching energy suppliers, what should I consider?")
• Asking follow-up questions ("What about if I'm on a fixed income?")

ChatGPT is also good at adapting. If the first answer is too complicated, just say "can you explain that more simply?" It won't mind. Our guide to ChatGPT prompts for beginners has a list of questions worth trying if you're not sure where to start.

A real example: planning a holiday

Say you're thinking of a week in the Cotswolds in May.

You'd use Google to: check specific hotel prices, read recent reviews on TripAdvisor, find out if a particular village has parking, or look at a National Trust site's opening times.

You'd use ChatGPT to: get a suggested itinerary, understand the difference between two areas, ask "what's worth seeing that most tourists miss?", or get a packing list for a spring trip.

They work well together. Google for facts. ChatGPT for thinking.

The one thing ChatGPT gets wrong that Google doesn't

ChatGPT can sound very confident while being wrong. It's trained to write fluent, plausible text, which means it can produce incorrect information in a perfectly convincing way. This is called "hallucination" in AI circles.

Google links to real pages. If the page is from the NHS or Citizens Advice, you can trust it. ChatGPT has no sources attached by default.

The rule we follow: if the answer matters a lot (health, money, legal), verify it with Google or a trusted website. Use ChatGPT to understand, then double-check the facts.

Our guide to staying safe with AI covers this in more detail, including what not to share with any AI tool.

What about Perplexity and Gemini?

Perplexity AI is worth knowing about. It combines the search side (it actually looks things up live) with the AI explanation side. Every answer comes with numbered sources you can click. It's a good middle ground if you find yourself wishing ChatGPT could check the web.

Google Gemini is Google's own AI assistant. If you use Gmail or Google Docs, you may already have it. It's similar to ChatGPT but tends to connect better with other Google tools.

A quick cheat sheet

Use Google for: finding, shopping, local searches, news, images, maps.

Use ChatGPT for: explaining, writing, summarising, brainstorming, conversation.

Use both for: anything complex. Let ChatGPT help you think, then check the facts.
