01
Getting started — straight from your Google account
There is nothing new to sign up for. Start with the account you already use.
001
Go to gemini.google.com and sign in with the Google account you already use. That is all it takes.
002
If you have an Android phone, the app may already be installed. Look for it in your app list.
003
On an iPhone, download the Gemini app from the App Store.
004
You can use most features for free. A paid plan raises the limits and adds advanced features.
005
Just type your question in Korean in the box at the bottom of the screen. There are no commands to memorize.
006
Your past conversations stay in the left-hand menu. To pick one up again, tap it.
007
If you do not want your conversations saved, you can turn that off under Activity in Settings.
008
If you save information about yourself in Settings, you will not have to explain your background every time.
009
If the text is too small, use your browser's zoom. On a phone, increase the font size in the app.
010
The copy button under each reply lets you paste the result straight into a document or a KakaoTalk message.
02
Your first question — how it differs from search
Search gives you links. Gemini gives you an organized answer.
011
Search gives you a list of links, while Gemini gives you an organized answer. They serve different purposes.
012
Do not ask in a few words like "restaurants nearby." Add your situation. For example: a quiet Korean set-menu restaurant to take my parents to.
013
Under an answer, the source-check feature shows the links behind it. For anything important, be sure to click through.
014
Saying "put it in a table" makes comparing much easier.
015
If you do not get the answer you want, narrow it down by adding one condition at a time.
016
For recent news, it answers together with search, so it is strong on questions where the date matters.
017
The button that regenerates the answer lets you see a different take.
018
If a long answer is too much, set the length yourself, for example "in 5 lines."
019
For foreign-language material, paste it in and say "summarize in Korean."
020
If you want to keep a question, rename the conversation so it is easy to recognize.
03
Asking with photos and screens
If something is hard to put into words, take a picture and ask.
021
You can upload a photo and ask "what is this?" Machine parts, plants and road signs all work.
022
If you photograph a paper document and upload it, it reads the text and organizes it for you.
023
Photograph a foreign-language menu or notice and you get a translation along with an explanation.
024
You can photograph a medicine envelope or instruction sheet and ask how to take it, but get final confirmation from a pharmacist.
025
You can also photograph your phone screen and ask, "What should I tap here?"
026
It can usually read handwritten notes too. Try having it organize the notes you took in a meeting.
027
For a photo that contains a table, say "move this into a table" and it formats it so you can paste it into Excel.
028
Cover up personal information in photos before you upload them. Name tags and badges are easy to catch by accident.
029
Blurry photos get misread. Retake them straight on, in good light.
030
Make it a habit to check what it read against the original once.
04
Gems — build your own helper
Save the tasks you ask for often as a helper, and call on it whenever you need it.
031
A Gem is your own helper, with a task you ask for often saved in it.
032
Give it a clear purpose, like a "résumé polishing helper," and write down its rules.
033
If you put a tone of voice and things to avoid in the helper's description, it follows them every time.
034
If you add the materials you use often, you will not have to repeat the background.
035
Keeping separate helpers for work and personal use stops the answers from getting mixed up.
036
It does not need to be perfect from the start. Fix the rules one line at a time as you use it.
037
There are also ready-made helpers. Try one first, and change it into your own if you need to.
038
If you make a helper that summarizes job postings, you can organize each week's postings in the same format.
039
Name your helper so its purpose is obvious. It will be easier to find later.
040
If the results are off, fix the helper's rules. That is better than correcting your instructions every time.
05
Using it with Gmail and Google Docs
Draft emails and tidy up documents right where you already work.
041
You can create an email draft right in Gmail. It takes the context of the email you received into account.
042
If you call up a draft in Google Docs, it writes directly inside the document.
043
You can have it answer based on your own files in Drive.
044
If you have it summarize a long email thread, you quickly see what you need to reply to.
045
If you get stuck on a spreadsheet formula, describe in words what you want to do and ask for the formula.
046
For scheduling emails, give it conditions such as "polite, with three suggested times" and the result comes out clean.
047
With a work account, available features may differ depending on your administrator's settings.
048
Check the facts and numbers yourself before putting them in a document.
049
For presentations, it is faster to build the outline first and fill in the slides afterward.
050
When working with business files, check your company's security rules first.
06
Deep Research — have it dig deep
It looks through many sources and turns them into a single report.
051
Deep Research is a feature that finds and reads many sources on its own and organizes them into a single report.
052
Choose Deep Research from the tools menu next to the input box, then write the topic you want researched.
053
By default it relies on Google Search, and you can add your own files, Gmail or Drive as sources.
054
It takes a few minutes to produce results. You can have other conversations while you wait.
055
It suits topics whose material is scattered, such as market research, competitor comparisons and policy trends.
056
It shows you its research plan first. If the direction is wrong, correct it then.
057
Click the source links in the report and check the original before you quote anything.
058
You can export the results to a document or share them.
059
Free accounts have a limit on how many times you can use it. Save it for the topics that matter.
060
If you research the other company and its industry before proposing an advisory engagement, it changes the quality of your first meeting.
07
Creating and editing images
Make your own pictures for presentations and promotional materials.
061
If you describe a picture in words, such as "make me a picture of...," it creates the image.
062
The more specifically you describe the scene, mood and colors, the closer you get to what you want.
063
You can keep talking and ask it to revise the image it made.
064
It works well for presentation covers and blog illustrations.
065
If a person's face looks awkward, ask again with a different angle or composition.
066
Do not make images that imitate real people or trademarks. They can lead to disputes.
067
Korean text inside images often comes out garbled. Add the text yourself in an editing tool.
068
If you plan to use an image commercially, check the scope of use in the service's terms.
069
You can also edit your own photo, for example by changing only the background.
070
Think ahead about whether this is a situation where you must disclose that an image was made with AI.
08
NotebookLM — study with your own materials
It answers only from what you upload, which cuts down on made-up answers.
071
NotebookLM is a tool that answers only from the materials you have uploaded.
072
Because it does not invent anything beyond your materials, the burden of fact-checking drops considerably.
073
Put in a job posting, a contract or a textbook and ask what you want to know. It also shows where in the material the answer comes from.
074
You can make an audio summary of your materials and listen to it on the go.
075
When you have a lot to study, ask it to pull out a list of key questions.
076
If you put several documents in one notebook, it also compares the differences between them.
077
It is especially well suited to preparing for certifications and exams.
078
Another good way to use it is to gather your career materials and pull out supporting evidence for each application.
079
In Gemini's research feature, you can also use a notebook as a source.
080
When you add sensitive materials, keep the sharing setting private.
09
Using it on your phone and by voice
Give instructions by speaking, even when you are on the move.
081
In the phone app, tap the microphone and ask by speaking. It is faster than typing.
082
You can also listen to the answer aloud, which is handy when you are on the move.
083
On Android, you can call it up right from the screen and ask about what you are looking at.
084
It may mishear dialect or fast speech, so speak clearly and slowly.
085
Recognition gets worse in noisy places. Use it somewhere quiet.
086
You can continue a conversation you started on your phone on your computer.
087
Do not use it while driving. Use it after you have stopped.
088
If the dictation is wrong, just fix that part by hand and send it again.
089
An answer you received by voice also stays on screen as text, so you can copy it later.
090
When you are in a hurry, such as taking notes during a call, save them by voice and have it organize them later.
10
Checking and staying safe
Be ready for when it is wrong, and know what never to upload.
091
An AI answer is reference material, not established fact. Always check numbers and dates.
092
Use the source-check feature to open the links behind an answer and read the original.
093
For medical, legal and tax matters, use it only up to a draft and get an expert to confirm.
094
Never enter a resident registration number, bank account or password under any circumstances.
095
If material contains other people's personal information, remove their names before you use it.
096
You can delete your conversation history in Settings, or turn off saving.
097
For company materials, check your company's internal rules first.
098
Features and plans change often. For the latest details, check Google's official help center.
099
The difference between free and paid is mainly limits and advanced features. If you are not in a hurry, learn on the free version.
100
The final judgment is made by a person. Read it once more before you send it.
