AI WORLDUsing Gemini in Gmail and Docs to save time
Learn how to use Google's built-in AI helper to summarise chaotic email threads, draft quick replies, and polish your documents.
Hook: Imagine having a friendly assistant sitting right inside your inbox and word processor, ready to clear your desk of drafts and summaries. This guide is for busy professionals who want to reclaim hours lost to repetitive typing and endless email chains.
- You will need a Google Workspace account (business or personal) with Gemini enabled.
- Open your Gmail and Google Docs in a web browser on your computer.
Summarise a long email thread in Gmail
When you return to work and find a thread of 15 back-and-forth emails, you do not need to read every single line. Gemini can digest the conversation and give you the key points.
Open a long email conversation. Look at the top right of your screen or near the top of the email for a small, sparkling star icon (this is the Gemini button). Click it, and a side panel will slide open.
"What are the key decisions made in this thread, and what are the next action items for me?"
Draft a quick email reply
Instead of staring at a blank screen trying to find the perfect polite words, let the AI write the first draft.
Click reply on an email, then look for the pen icon with a little sparkle next to it (often called the "Help me write" button) at the bottom of your compose window.
"Write a polite email declining the invitation to Tuesday's meeting because of a schedule conflict, but offer Thursday at 2:00pm as an alternative."
Gemini will show you a draft. You can click "Insert" to put it into your email, then edit it to sound like you.
Start a document from scratch in Google Docs
Starting a new business proposal or project outline is often the hardest part of writing. You can use Gemini in Google Docs to build a solid foundation in seconds.
Open a blank Google Doc. Click on the empty page, and look for the floating icon of a pen with a sparkle on the left margin. Click it to open the writing assistant.
"Create a professional project proposal outline for a local garden landscaping job, including sections for scope of work, timeline, and estimated costs."
Click "Create", and watch the AI build the structure for you to fill in.
Refine and polish your writing
If you have written a paragraph but feel it sounds a bit too casual, or perhaps too long-winded, you can ask the AI to reorganise the text.
Highlight the text you want to change in Google Docs. A small sparkle icon will appear near your cursor. Click it to see a list of options like "Formalise", "Shorten", or "Rephrase".
"Rewrite this to be more engaging for a customer newsletter."
- Sending without a human double-check: AI is highly capable, but it can occasionally experience a "hallucination" (when an AI confidently makes up a fact that is not true). Always proofread drafts before hitting send.
- Being too vague: If you just write "draft an email about the project", the AI has to guess the details. The more specific you are with your instructions, the better the result.
- Sharing sensitive secrets: Do not paste highly private customer information, passwords, or top-secret legal details into the prompt box. Keep your prompts professional but general.
Open your Gmail right now, find the last email newsletter or long conversation you received, click the Gemini star icon in the top right, and select "Summarise this email". See how accurately it captures the main points in just two seconds!
