Phase 4 · Gemini · Level 1 · Foundations
Gemini's limitations (and how to work around them)
By the end, you'll be able to…
- Explain why a Gemini feature can be missing without anything being broken
- Use a reliable check for a Gemini answer instead of trusting its confidence
- Choose the right fallback when the in-app features aren't there
Why it matters
Knowing where a tool falls short is what turns a nervous beginner into a confident user. Gemini is useful, but it has real limits, especially around which features you actually get and how much to trust what it says. Knowing them upfront saves frustration and keeps you safe.
Why this lesson matters
We're not here to sell Gemini. It's a capable assistant, but an honest look at its weak spots makes you more capable, not less. Here are the three that trip people up most, plus two quieter ones, each with a workaround you can actually use. We'll keep the Fernway Group in mind, where Maya, Tom and Priya are all on slightly different accounts and keep seeing different things.
Limitation 1: The in-app features depend on your account
This is the big one, and it's confusing. The Gemini help inside Gmail, Docs and Sheets (the side panel, "Help me write", summaries) is not available to everyone. It depends on your account type and, often, a plan. A personal free account, a paid Google AI plan, and a work or school account on Google Workspace can each show different things. So Maya might rave about the side panel in Gmail while Tom opens the same app and sees nothing, and neither account is broken.
Work around it: don't assume a missing button is a fault. If the in-app helper isn't there, use the free app at gemini.google.com. It does the same jobs, just with a little copying and pasting. And before paying for anything, check what your specific account already includes on Google's Using Google Workspace with Gemini page. Rather than hunt around blindly, you can even ask Gemini to tell you what to look for.
I'm signed in to Gemini but I can't find the "Help me write" or side panel features inside Gmail. In plain steps, how do I check whether my account includes them, and what should I do if it doesn't?
Why this works: Instead of endlessly searching for a button that may not exist on your plan, this gets you a clear checklist of where to look and what it means if it's absent.
Limitation 2: It can be confidently wrong
Like every assistant in this course, Gemini can state things that simply aren't true, and say them with total confidence. It can also invent sources that look real but aren't. This is hallucination, plausible-sounding output that's actually wrong. Because Gemini is a Google product, people expect it to be as reliable as Google Search. It isn't: it predicts likely text rather than looking up guaranteed facts.
Work around it: use Gemini to get oriented, not for final answers on anything that matters. For health, money, legal, or facts you'll act on, check it against a trustworthy source. And note the trap in the next prompt: asking "are you sure?" is not a reliable check, because it can simply be confidently wrong a second time.
Give me the figure I asked for, and list the sources you're basing it on with links. I'm going to check them, so only include sources you're confident actually exist.
Why this works: Asking Gemini to cite sources makes a claim checkable, but the check is you opening the links, not Gemini's confidence. It gives you something to verify rather than something to trust.
If you open those links and they don't say what Gemini claimed, or don't exist, you've just caught the mistake the polite way. That habit, not the tool's tone, is what keeps you safe.
Limitation 3: The integration can feel inconsistent
Because Gemini's in-app help rolls out gradually and differs by account, it can feel patchy. You might find "Help me write" in Gmail but not the exact same thing in Docs, or see a feature one week that looks different the next. Button labels and positions move too. Two colleagues following the same guide can end up on different screens.
Work around it: treat the exact buttons as something to look for on the day, not to memorise. If a feature isn't where a guide says, it may have moved or may not be on your account. The free app is your steady fallback. It behaves the same for everyone, so when consistency matters, that's where to go.
I can't find the summarise feature in Gmail today. I'll paste the email here instead. Summarise it in three bullets and tell me what the sender is asking me to do. Here's the email: [paste the email]
Why this works: When the side panel is missing or has moved, this reproduces the same result in the app that works for everyone, with no dependence on which features your account happens to have.
Limitation 4: It only knows what it can see (and what you tell it)
Inside Gmail or Docs, Gemini can work with the email or document that's open, but not with things it can't see. It doesn't know facts that live only in your head, and it won't magically know a date or decision that isn't written down. Ask it to confirm a meeting time you never gave it, and it may omit the time or guess one.
Work around it: hand it the missing facts in your prompt. If a reply needs a time, a name or a choice that isn't in the email, include it. Otherwise Gemini may guess, and guessing is where it goes wrong.
Limitation 5: Your privacy habits still apply
Convenience makes people careless. Because Gemini can sit right inside your email, it's tempting to let it loose on anything. But the usual rule holds: be thoughtful about what you feed any AI tool, especially other people's personal details or confidential work information.
Work around it: keep sensitive details out where you can, and if you're using Gemini for work, check whether your organisation has approved it and on which account. A personal Gemini account is not the place for a confidential Fernway contract.

Common mistakes
- Assuming a missing feature is a fault. It's almost always "not included on your account", not "broken". Check your plan, then use the app.
- Trusting confidence as accuracy. A fluent, assured answer can still be wrong. Verify anything that matters against a trustworthy source.
- Using "are you sure?" as your check. It isn't one. Gemini can be confidently wrong twice. Check the actual source instead.
- Memorising button positions. They move. Learn the job, keep the app as your fallback.
- Over-trusting because it's a Google product. The brand doesn't make it Search. It predicts likely text, so the same checking discipline applies as with any assistant.
Keeping current
These limitations are durable in shape, but the details (which accounts get what, where the buttons live) change constantly. When something here doesn't match your screen, trust your screen and check Google's Gemini Apps updates and Gemini Apps Help. Accurate as of 13 July 2026.
