At a glance

What it is
Google’s general-purpose AI chatbot. Available as its own app, but also baked into Gmail, Google Docs, Google Search, and every modern Android phone.
Cost
Free version is genuinely capable. Gemini Advanced is £19/month and includes the smartest model plus 2TB of Google storage.
Where to find it
gemini.google.com on any browser, the Gemini app on Android, or the “Ask Gemini” sidebar in Gmail and Docs.
Privacy
By default, Google reviews some conversations to improve the service. You can switch this off in your Gemini activity settings.
Walter’s take
The “Ford Focus” of AI — not the most exciting, but you probably already own one and the boot is bigger than you’d expect.

Section 01What is it, really?

Gemini is Google’s family of AI models, accessible through a chatbot at gemini.google.com. The interface looks much like ChatGPT — a chat box at the bottom, an answer above. The genuinely useful difference is that Gemini is plumbed directly into the rest of your Google life.

Ask it about a flight in your inbox, a meeting in your calendar, or a document in your Drive — and it can actually go and look. It also has live access to Google Search, which means it knows about today’s news in a way ChatGPT and Claude don’t (without paying extra). For people who already live inside Gmail and Docs, that’s a meaningful advantage.

Section 02What it’s genuinely good at — and not

Genuinely useful for

  • Searching your own Gmail and Google Drive in plain English
  • Drafting replies inside Gmail without leaving the inbox
  • Live web answers — current news, prices, weather, sports
  • Image generation (free, included)
  • Reading screenshots and photos you’ve taken
  • Voice conversations on your Android phone

Don’t trust it with

  • Long-form writing — it’s a bit blander than Claude or ChatGPT
  • Anything where you’d rather Google didn’t see it
  • Subtle creative work — tone tends to be safe and corporate
  • Anything you need without checking — it still hallucinates
  • Medical, legal or financial decisions you’ll act on
  • Avoiding the Google ecosystem (this is the deepest into it)

Section 03How to get started in five minutes

  1. Go to gemini.google.comIf you’re already signed into a Google account, you’re ready. No separate sign-up needed.
  2. Try a question that uses live web dataAsk “what’s the weather in Brighton tomorrow?” or “who won the football last night?” — this is where it beats free ChatGPT.
  3. Try the @ symbolType @ in the chat box and you can pull in Gmail, Drive, YouTube and Maps. Try “@Gmail summarise emails from my bank this month.”
  4. On Android, hold the power buttonGemini replaces Google Assistant. Hold the power button (or say “Hey Google”) and you can ask questions hands-free.
  5. Switch off training data sharing if it bothers youGo to myactivity.google.com → Gemini Apps Activity. You can turn it off without losing access.

Section 04A prompt to try right now

Gemini’s superpower is reaching into your inbox and calendar. Try this — it’s the kind of thing only Gemini can do well:

@Gmail look through my emails from the last 30 days and find anything that looks like a bill, subscription renewal, or one-off charge. List them as a table with the company, the amount, and the date. Flag anything that looks unusual or that I might have forgotten about.
Walter’s tip

The @ symbol is the magic. Most people use Gemini without realising it can read their Gmail and Drive. Once you start using @, it becomes genuinely indispensable for finding things buried in old emails.

Section 05Things to watch out for

Privacy — the elephant in the room

You’re handing Google more access to your data than ever before. If you’re comfortable with Google reading your Gmail (which it already does for spam filtering), Gemini is a small extra step. If you’re not, this isn’t the AI for you.

Hallucinations still happen

Even with live web access, Gemini occasionally makes things up — particularly summarising long documents or quoting specific facts. Always check anything important.

Two different products, confusingly named

“Gemini” can mean three things: the chatbot at gemini.google.com, the AI features inside Gmail and Docs (called “Help me write”), and the model itself. They share a name but behave differently.

Section 06The honest cost breakdown

Free tier: Unlimited chats with the standard model, image generation, live web search, basic Gmail and Drive integration. Easily enough for most Google users.

Google AI Pro (£19/month): The smartest model (Gemini 2.5 Pro), longer responses, deeper Gmail and Docs integration, Veo video generation, and 2TB of Google One storage. Genuinely good value if you already pay for Google storage.

Google AI Ultra (£200/month): Maximum limits, earliest access to new models, full video generation. Almost certainly overkill unless you’re using AI professionally.

Walter’s verdict

The most useful AI you’re probably already paying for. Quietly excellent inside the Google ecosystem.

If you live inside Gmail, Drive and Android, Gemini is a no-brainer — it does things ChatGPT and Claude simply can’t. If you’re a Microsoft Outlook person who’d rather Google read fewer of your emails, give it a miss. The free tier is the best of the four for live web answers.
