Gemini in Gmail and Docs

The difference: Gemini can see what's on your screen

In the standalone app you copy text in and Gemini works on the copy. Inside Gmail and Google Docs it works the other way round: the Ask Gemini side panel and the Help me write button can already read the email thread or document you have open, so you skip the paste and just ask. That single difference, Gemini seeing your actual content, is what makes the in-app helpers worth learning.

One honest caveat before you look for these buttons. The in-app Gemini features in Gmail and Docs depend on your account type and, usually, a paid plan (an eligible Google Workspace edition or a Google AI plan). Two colleagues on different accounts see different screens; a missing button means "not included on your account", not "broken". Google's Using Google Workspace with Gemini page is the place to check what your account includes. Work accounts add one more wrinkle: beyond the base Workspace edition, an organisation can buy add-ons that switch specific Gemini features on for some staff and not others, so two colleagues on the same edition can still see different buttons. Either way the question is always "what does my account include", not "is it broken". If you don't see the side panel, everything below still works by pasting the same text into the free app at gemini.google.com. You just lose the "sees your screen" convenience.

Throughout this lesson we're back with the Fernway Group, our fictional practice company, and you're Tom Elliott, its Sales Lead, working through the email thread where he, Priya and Maya sort out a scheduling clash.

Gemini in Gmail: summarise, draft, search

Open an email or a thread in Gmail and look for Ask Gemini (often a small spark icon at the top right). Click it and a panel opens down the side. Three jobs it does well:

Summarise the open thread. With a long back-and-forth open, the panel offers a one-click summary, or you type "summarise this thread and tell me what was agreed and who owns what". Because it can see the whole thread, you don't paste anything.
Draft a reply. When composing or replying, the Help me write prompt lets you describe the email you want and get a first draft in the compose box, ready to edit.
Search your mail in plain English. You can ask the panel questions like "when did Priya say the new starters begin?" and it looks across your mailbox rather than making you remember search operators.

Here is the worked example. Tom opens the Fernway thread (five messages arguing about whether new-starter onboarding clashes with the Harlow renewal) and asks the panel to make sense of it.

Summarise an open thread in GmailGemini

Summarise this thread in three bullet points. Then tell me clearly what was finally agreed, the exact dates, and who agreed to do what. Only use what's in the thread.

Why this works: With the thread already open, the side panel can see all five messages, so you ask for exactly the shape you need, a summary plus who agreed to what, instead of pasting anything or reading it all yourself.

A good reply captures the real compromise: onboarding stays in the week of 18 August, but the sales-shadowing sessions move to Monday 25 August, and Maya agreed to redo the schedule and send it round. Now Tom drafts the confirmation without leaving Gmail. Notice he hands Gemini the exact dates. The panel can see the thread, but spelling out the decision stops it guessing.

Draft the reply with Help me writeGemini

Draft a short, warm reply from Tom confirming he's happy with the compromise: onboarding stays the week of 18 August, sales-shadowing moves to Monday 25 August. Thank Maya for the sensible idea. Under 80 words. Don't add any dates or details that aren't in what I've told you.

Why this works: Giving the sender, tone, length and the precise decision turns a blank reply into a describable target. The 'don't add dates I haven't given you' line is a guardrail against invented detail.

The draft lands in the compose box. It is a draft, not a sent email. You read it, tweak it, and only you press send.

Gemini in Docs: draft, then refine

Google Docs has the same idea in two forms. In an empty or part-written document you'll see a Help me write prompt; select existing text and you can Refine it: rewrite, shorten, elaborate, or change the tone. There's also an Ask Gemini side panel that can summarise the document or pull in material from your Drive and Gmail.

Say Tom needs a short internal note to the wider team explaining the agreed schedule. He starts in a blank Doc and uses Help me write.

Draft a note with Help me write in DocsGemini

Write a short internal note to the Fernway team explaining the August plan: new-starter onboarding runs the week of 18 August as planned, and the sales-shadowing sessions move to Monday 25 August so the sales team can focus on the Harlow renewal. Friendly and reassuring. A short heading and two short paragraphs.

Why this works: A named audience (the whole team), the facts, and a length give Docs a target. Asking for a heading and short paragraphs means you get something structured you can publish, not a wall of text.

The first draft is close but a little stiff. Rather than retype, Tom selects it and refines, the same iterate-don't-restart habit from Phase 0, except the text stays in the document.

Refine selected text in DocsGemini

Make this a bit warmer and less corporate, and add one line thanking Maya and Priya for sorting the clash. Keep it roughly the same length.

Why this works: Refining keeps everything that already worked and changes only what you flag. Selecting the text first tells Gemini exactly what to act on, so you steer the draft instead of starting a new one.

You can refine as many times as you like: "shorter", "add a bullet list of the key dates", "more formal for a client version". Each pass edits the draft in place. That tight loop, on text Gemini can already see, is the whole reason to work inside Docs rather than the standalone app.

When to use which

Reach for the in-app side panel when the content is already in Gmail or Docs and you want to act on it in place: summarising a thread, drafting a reply, reshaping a paragraph. Reach for the standalone app when you're starting from scratch, when you want to keep confidential material out of a document, or when your account simply doesn't include the in-app features. They're the same underlying assistant; you're only choosing whether it works on your live screen or on text you paste.

Example prompts

Catch up on a thread you were cc'd onGemini

Summarise this thread for someone who was only cc'd. What's been decided, what's still open, and is there anything that needs a reply from me?

Why this works: Asking specifically for decisions and open questions, rather than a recap, turns a summary into something you can act on. You learn what needs a reply, not only what was said.

Adjust a draft's tone before sendingGemini

Rewrite this draft to be a little more casual and warm. It's going to a colleague I know well. Keep it under 60 words and keep the request clear.

Why this works: Naming the reader and the feeling you want ('respectful of their time', 'no pressure') gives Gemini a concrete target, so the rewrite matches the relationship rather than a generic 'professional' default.

Find something in your mail without operatorsGemini

Search my mail: when did we agree the Harlow renewal date, and who confirmed it? Quote the line and tell me which email it's from.

Why this works: Plain-English mail search saves you remembering exact senders or dates; asking Gemini to quote the line means you can verify the answer against the real email rather than trusting a paraphrase.

Common mistakes

Expecting the side panel on every account. Ask Gemini and Help me write depend on your account type and usually a paid plan. If they're missing, you're not doing anything wrong. Use the free app instead.
Assuming "it can see the thread" means "it got the thread right". The panel can still misread a long exchange or drop a date. Skim the real thread against the summary before you act, especially for anything with a deadline in it.
Letting a drafted reply send itself. Help me write puts a draft in the compose box; it doesn't send. Read every word; it goes out under your name, not Gemini's.
Over-trusting mail search. "When did we agree Harlow?" can return a confident answer built from the wrong email. Ask it to quote the line and which message it came from, then glance at that message. A fluent answer is not a checked one.
Pasting confidential detail into a shared Doc. Anyone with access to the Doc can see what you put in it. Keep sensitive material out, and check your organisation's rules on what may go into Gemini at all.

Keeping current

Google renames and reshuffles these in-app helpers often: button names, where the panel lives, and which accounts get what all move. How Gemini is licensed at work moves too: the AI Expanded Access add-on introduced in February 2026, for instance, changed which staff get which features on top of their Workspace edition, so if a colleague has a button you don't, an add-on is one likely reason. Your admin, or the Using Google Workspace with Gemini page, can confirm what your organisation has switched on. When your screen doesn't match this lesson, trust your screen and check Google's official pages: Collaborate with Gemini in Gmail and Collaborate with Gemini in Google Docs.
