Generic AI replies often sound like they came from a stranger: too formal, too long, or full of phrases you would never say. This guide shows you how to teach Gemini your writing habits, then use those habits to draft replies you can send after a quick review. You'll finish with a reusable style summary and a repeatable routine.

Gemini can't know what you actually decided or what a colleague really meant. It can draft the words, but you choose the facts, the dates and the final message.

💡 Tip: tap a step’s number when you finish it — a green tick appears and your browser remembers how far you got.

✅ Before you start

A Gmail account where Gemini features are available to you. Look in Gmail for a sparkle or Gemini icon. Some features may require a paid Google plan, and on a work or school account your administrator may have turned them off. Check Google's official help or pricing pages for current plan details rather than relying on this guide.
Three emails you wrote yourself: one short, one polite decline or follow-up, and one longer update. Copy them into a note or document.
You should already know how to open a Gemini chat and paste text into it.
Time: about 25 minutes the first time, then about 5 minutes per reply.

Step 1 of 6

Confirm Gemini is on in Gmail

Open Gmail in a web browser on your computer and click Compose to start a new message. Look for a small sparkle or Gemini icon, or a "Help me write" style option, in the compose window or a side panel. Clicking it should open a writing panel with a text box.

If nothing like this appears, the feature may not be on for your account yet, or your plan may not include it. In that case, you can still use the Gemini chat in Steps 3 and 4 by copying and pasting emails into it.

✅ You'll know it worked when

a Gemini writing option appears and offers to help you write or reply.

🔄 If it looks different

on a phone, check the Gmail app's menu or toolbar for a Gemini option.

Step 2 of 6

Collect three emails you wrote

Open your Sent folder in Gmail and find three messages you're happy with. Pick variety: a short one, a polite decline or follow-up, and a longer update. Copy each body into a single document, separated by a line that reads Email 1, Email 2 and Email 3. Variety matters because one email alone can make Gemini copy a single pattern.

Before you paste anything, remove personal details such as phone numbers, account numbers, home addresses and names you wouldn't want shared. If you're using a work account, follow your organization's rules about sharing internal information with AI tools.

If you have only one or two good samples, that's fine for now. Use what you have and add more later.

💬 ExampleLabel each sample like this: "Email 1: [paste short email here]"

✅ You'll know it worked when

you have three cleaned-up emails in one place, ready to paste.

Step 3 of 6

Ask Gemini to describe your writing style

Open a new chat with Gemini. Look for a New chat button or a plus icon, then paste your three emails with the instruction below. Gemini should reply with a short bulleted summary covering greeting, sentence length, tone, sign-off and phrases you repeat.

Read the summary carefully. If it sounds generic, reply with: "Quote one phrase from each email that shows my style." Those quotes make the pattern easier to judge. Once the summary is accurate, copy it into your notes and label it "My email style." This is your style guide for every future draft.

If the response is cut short or doesn't list all five points, ask it to continue from where it stopped.

💬 Try typing thisType your own details into the dashed boxes, then copy."Here are three emails I wrote. Describe my writing style in five short bullets: greeting, sentence length, tone, sign-off, and phrases I repeat. Email 1: Email 2: Email 3: "➤

✅ You'll know it worked when

Gemini's bullets match how you actually write, and you can recognize yourself in them.

Step 4 of 6

Draft a reply to a real email

Open an email in Gmail that needs an answer. Click the reply option, then open Gemini's writing panel. If the panel has a box for instructions, paste your style summary there along with what you want to say. If it doesn't, copy the incoming email and your style summary into the Gemini chat from Step 3 instead.

Gemini will usually produce a draft within a few seconds. Give it clear facts: the answer you want, any date or number that must appear, and the length you prefer. If the draft misses the point, don't start over. Tell it what to change, because a precise correction works better than a vague "try again."

💬 Try typing thisType your own details into the dashed boxes, then copy."Using my style summary, draft a reply to the email below. Say yes to Thursday's meeting, ask for the agenda, and keep it to short sentences."➤

✅ You'll know it worked when

a draft appears that answers the email and uses your usual greeting or sign-off.

Step 5 of 6

Review, tweak and send

Read the draft out loud. This is the fastest way to catch clunky phrasing. Check every name, date, number and promise, because Gemini can get details wrong or fill gaps with guesses. Then edit by hand: change one or two sentences so the draft sounds more like you. If the tone is off, tell Gemini exactly what to change.

Only send when you'd be comfortable saying every sentence yourself. If you find yourself rewriting most of it, your style summary may need more detail, so go back to Step 3 and add a sample that matches this situation.

💬 Try typing this"Shorten the second paragraph, and keep my usual sign-off."➤

✅ You'll know it worked when

you can send the reply after changing no more than two sentences, and every fact in it is correct.

Next step ↓

✏️ Sketch — your screen may look a little different

Step 6 of 6

Reuse your style summary for future emails

Create a note called "Email templates" and paste your style summary at the top. Under it, save one reusable request you can copy for each new email. Whenever you need a reply, start a fresh Gemini chat, paste the summary, then paste the email you're answering.

Don't count on Gemini remembering your style between chats. Some features may keep information across conversations, but that can change, so paste the summary each time. Every few months, add a new sample email and update the summary so it keeps up with how you write now.

💬 Try typing thisType your own details into the dashed boxes, then copy."My style summary: . Now draft a reply to this email: ."➤

✅ You'll know it worked when

a new chat, started from your note, produces a draft that sounds like you on the first try.

⚠️ Common mistakes

Sending without reading the draft. AI can invent dates, names or promises. Fix it by reading aloud and checking every fact before you click send.
Using only one sample email. A single message can make every draft sound identical. Fix it by giving Gemini three varied emails, including one that is short and one that is longer.
Pasting private details without thinking. Emails often contain phone numbers, account details or confidential work information. Fix it by removing personal details first and following your organization's rules if the account is for work.

🚀 Try it now

Open one short email you've been putting off, copy one of your own short sent emails into a Gemini chat, and ask it to describe your style in three bullets. Then ask it for a two-sentence reply to the email you're putting off. Read the result aloud, change one word, and decide whether to send.
