How to Use Gemini in 2026: A Step-by-Step Beginner's Guide

To use Gemini, go to gemini.google.com or open the Gemini app, sign in with your Google account, type what you need in the box at the bottom and click Submit. Give it the details a colleague would need. From the same box you can attach files, start Deep Research or open Canvas, and you can edit your prompt if the first answer misses.

The first few prompts usually go one of two ways: Gemini gives you something surprisingly useful, or something so generic you wonder what the fuss is about. The difference is almost always in how you ask. This guide walks through the basics in the order you'll need them, from a first prompt to the features that save real time once you're comfortable, such as Deep Research, Canvas, skills and scheduled actions.

If you're still deciding whether Gemini is for you, start with my explainer, What Is Google Gemini?, which covers the plans, prices and privacy settings. This post is about using it.

How to start using Gemini

You can start using Gemini free with any personal Google account, on the web or in the mobile app. Google's Use Gemini Apps help page gives these steps for a computer:

1. Go to gemini.google.com and sign in.
2. Type your prompt in the text box at the bottom.
3. To include a file or image, click Add files and follow the steps.
4. Click Submit.
5. For a fresh topic, click New chat at the top left (it sits under Menu when the sidebar is closed).

Sign in before you do anything serious. Google's page notes that file uploads and other features aren't available without signing in. On a phone, the Gemini app works the same way: type, talk or attach, then send.

How to write a prompt that gets a useful answer

A good Gemini prompt reads like a clear request to a capable colleague: what you want, the background, and the form the answer should take. Google's own prompting tips boil down to five habits: write naturally, be clear and concise, give context, use specific keywords, and split complex work into separate prompts.

The context is the part people skip. Before a vendor renewal call, I typed "summarize this proposal" and got a tidy, useless paragraph. What worked was saying why I needed it and what I'd do with it:

I have a 30-minute call tomorrow with a vendor about renewing our project software.
Attached is their renewal proposal.
1. Summarize what changes from our current contract in five bullets.
2. List anything that raises our cost or locks us in longer.
3. Suggest three questions I should ask on the call.
Keep it under 250 words and plain enough to read on my phone.

Notice the numbered asks. When a request has three parts, numbering them makes it far less likely one gets dropped. And "plain enough to read on my phone" is a format instruction, which is the cheapest way to stop Gemini from writing an essay.

How to choose a model in Gemini

Gemini picks a model for you by default, and you can switch from the model menu in the chat box. Google's About Gemini models page says auto selection routes each prompt to the most efficient model and thinking level, and that most prompts go to Flash-Lite for quick answers. Models with a lock icon need a plan upgrade.

Auto selection is the default whatever your plan; the table shows what you can choose by hand. Google describes Argon as its top-tier model, so it's the one to try when Pro still isn't getting a hard task right.

You can also set a thinking level of Low, Medium or High, and Google says it defaults to Low. My habit: leave it on auto for everyday questions, and only raise the thinking level for something with several steps, like comparing two contracts or planning a project timeline. For a quick rewrite, extra thinking just means extra waiting.

How to upload a file and ask about it

To ask Gemini about a document, click Add files below the text box, choose the file or image, then type your question. The question matters as much as the file. "What's in this?" gets a summary; "What does this commit me to, and by when?" gets the dates and obligations you actually care about.

For work files, check your company's policy first. On a personal account, your activity settings decide how Google keeps and uses what you upload, and my Gemini explainer walks through them in its privacy section before you share anything sensitive.

How to fix an answer you don't like

When an answer misses, edit your prompt rather than starting over. Google's help page gives three ways to steer a response:

• Edit the prompt. Click Edit text to the right of your prompt, change it, and click Update. Gemini writes a new response.
• Look at other drafts. Above the latest response, click View other drafts (or Show drafts) to see alternatives for some prompts.
• Just reply. "Shorter." "Less formal." "Use the numbers from page 3." Follow-ups are usually faster than rewriting the original.

Then check it. Google's page says plainly that Gemini can make mistakes and you shouldn't rely on it for professional advice. Anything with a number, a date, a name or a quote goes back to the source before it goes into an email.

How to use Deep Research in Gemini

Deep Research has Gemini search many sources, write a plan, and come back with a full report with sources, usually in about 5 to 10 minutes. It's on the free plan with lower limits, per Google's plan page. The steps on a computer, from Google's Deep Research help page:

1. Go to gemini.google.com.
2. In the text box, click Add files, then Deep Research.
3. Optional: click Sources to choose where it looks. Google Search is on by default; you can add Gmail or Drive if they're connected.
4. Type your research question and click Submit.
5. Read the plan Gemini drafts. Click Edit plan to change it.
6. Click Start research. You can leave the chat; Gemini tells you when it's done.
7. When the report is ready, click Open.

The plan step is where you get a better report. I once asked for an overview of how project management tools price their plans, and the draft plan included enterprise products I'd never consider. One edit to limit it to tools for small teams, and the report came back about the options I could actually buy. From the report's panel, Share & export sends it to Google Docs.

How to use Canvas to write and build

Canvas opens a document or code editor beside the chat, so you can work on a draft with Gemini instead of copying answers back and forth. From Google's Canvas help page:

1. Below the text box, click Add files, then Canvas.
2. Describe what you want, such as a one-page project brief or a simple web page.
3. Click Submit. The draft opens in the Canvas panel.
4. To change part of it, select the text in the panel and type what you want changed, or click Suggest edits.
5. When it's done, click Share & export at the top right for Export to Docs, Copy contents and more.

Canvas can also turn a doc into slides, a quiz, an infographic, a web page or an Audio Overview. Selecting a single paragraph and asking for a change is the habit worth learning, because the rest of the document stays as you left it.

How to talk to Gemini with Gemini Live

Gemini Live is a spoken conversation you can interrupt, and on a phone you can share your camera or screen. It's included on the free plan, according to Google's plan page. On an iPhone, from Google's Gemini Live help page:

1. Open the Gemini app.
2. Tap Live at the bottom (or swipe left).
3. Follow the on-screen setup the first time, then start talking.
4. Tap the Camera icon to show Gemini what you're looking at, or Turn on screen sharing to share your screen.
5. Tap Hold to pause with the mic off, or End to finish and see the transcript.

I use Live to rehearse. Walking to a meeting where I had to explain a budget change, I talked it through out loud and asked Gemini to push back like a skeptical finance lead. Hearing my own weak spots before the room did was worth more than another pass at the slides.

How to save instructions you repeat as a skill

A skill is a set of saved instructions Gemini can reuse, so you stop pasting the same paragraph into every chat. Skills are replacing Gems: Google's transition page says personal accounts move in November 2026, existing Gems are recreated as skills automatically, and work and school accounts follow in 2027. To create one on a computer, per Google's skills help page:

1. Go to gemini.google.com.
2. In the sidebar, click Customize. It may be tucked under More.
3. At the top, click Skills, then Create.
4. Choose Create with Gemini and describe the skill, start from a template under Recommended, or click Create manually to write a name, description and instructions yourself.
5. In any chat, type / (or @ if your app has the newer shortcut) and pick the skill. Gemini can also use an active skill on its own when it fits.

You need to be 18 or older with Keep Activity turned on, and Google says skills work without a paid plan. My first skill was my weekly update: three sections (done, next, blocked), plain sentences, no more than 150 words. Now I paste my rough notes, call the skill, and the format is right the first time. Google's advice for writing one matches that: say when to use it, keep it focused and include an example of the output you want.

How to schedule Gemini to do something regularly

Scheduled actions let Gemini run a prompt at a set time, such as a weekday morning summary. To set one up, Google's scheduling help page says to type a prompt that includes when and how often, then click Submit. Gemini replies with a summary of the schedule.

Every weekday at 7:30 a.m., give me a five-bullet summary of news about the commercial real estate market in Chicago, with a link for each item.

• 10 active schedules is the most Google allows at once.
• Manage them under Scheduled in the sidebar: edit, pause, resume or delete.
• Keep Activity must be on, and the feature is still rolling out to personal accounts.
• Gemini prepares the response within the hour before delivery, so fast-moving numbers like stock prices won't be live.

How to manage your Gemini chats

Your past chats sit under Recent in the sidebar, and each one has a More menu. From Google's chat management page:

• Pin a chat you'll come back to; pinned chats stay at the top of Recent.
• Rename a chat so you can find it later. "Vendor renewal questions" beats an auto-generated title.
• Delete a chat to remove it from your Gemini activity too. On work or school accounts, your admin controls this and you can't delete chats.
• Use Temporary chat, next to New chat, for anything you don't want saved in your history. Google's help page says temporary chats can't use connected apps or Gems.

To keep an answer outside Gemini, click Share & export below the response, then Export to Docs, which saves a new doc in your Google Drive, per Google's export help page.

Your first week with Gemini: a simple plan

The fastest way to learn Gemini is to use it on real work for a week, not on test questions. This is the order I'd suggest:

1. Day 1: Rewrite one email you're stuck on. Paste it in and say who it's for and what you need them to do.
2. Day 2: Upload a long document you've been avoiding and ask what it commits you to.
3. Day 3: Run one Deep Research report on a decision you're actually facing, and edit the plan before it starts.
4. Day 4: Draft something in Canvas and practice changing one paragraph at a time.
5. Day 5: Turn the instructions you typed most often this week into a skill.

By the end of the week you'll know whether the free plan's limits are enough. Google says limits refresh every five hours up to a weekly cap, and the paid plans raise them. If you're weighing Gemini against the alternative most people know, the side-by-side in Gemini vs. ChatGPT shows where each one is stronger.
