Gemini in Full, from Setup to 12 Hands-On Features

To put it bluntly, Gemini is not a chat window but an assistant wired into the Google ecosystem. Nail down the basics like memory and app integration first, then learn the 12 hands-on features in order. Follow it from start to finish and your setup is done.

1. Basic Setup: Turning It into Personal Intelligence

Turning On Memory

This is the switch that makes Gemini remember you. Turn on memory in settings and it reflects the preferences and facts from previous conversations in its next answers. To turn it on, activate the memory item in the Gemini app's settings menu. You can view and delete what it remembers as a list, so turn it on without worrying.

Google App Integration

Connect Gmail, Google Calendar, and Google Drive and searching mail or checking your schedule takes a single sentence. For example, requests like "find last week's quote email" or "tell me my free time next week" are handled right away. Just turn on the Google Workspace connection in the Apps or Extensions menu in settings.

Pre-entering Your Requests

This pins down your answer style and user information in advance. Save instructions like "always summarize in 3 lines" or "answer in a warm, friendly tone" and you won't have to repeat them every time. Write down your job and interests too and the answers become noticeably more personal.

Etc.: Memory Transfer and Usage Check

The memory transfer feature that imports conversations from other AI tools and checking your current plan's usage limit are in the same settings area. Free plans have a cap on how many times you can call advanced models, so check the limit indicator often.

2. The 12 Hands-On Features

3. Detailed Guide by Feature

Image and Video Generation

There is an order. First define the subject in one sentence, then add one sentence each for background, lighting, and art style. An example prompt:

A rainy Seoul alley at midnight, a person with an umbrella reflected in neon signs,
cinematic still lighting, realistic photographic style

If the first result disappoints, do not start over; keep going in the same conversation with "change this." It gets revised while keeping the style. For video, short clips of around 5 seconds are stable, and specify only one movement. Give "the person walks" and "the camera turns" at the same time and it breaks. If you need a person's face, check the portrait rights issue first.

The Canvas Feature

You do not need to know how to code. Say "make me a minesweeper game" and a working game comes out right away. Fine-tuning is done with sentences, like "add a flag feature" or "split difficulty into 3 levels." For a PPT draft, give the topic, the number of slides, and the audience together, like "10 slides for new-hire training." Check the result in the preview, and download any version you like as a file. Canvas content gets overwritten as the conversation grows, so save the final version immediately.

Deep Research

First, get a plan. Say "research the 2026 EV battery market" and Gemini shows a research plan first. Narrow the scope here, like "only the Korean market, focused on CATL and BYD." Decide the desired length up front too, like "about 5 pages of A4." Get in the habit of always scanning the source list in the result and separately verifying only the key figures. If a figure is wrong, the whole report collapses. When the research is done, get a 3-line summary and the full report from the same material separately. You need one for reporting and one for sharing.

YouTube Summary Analysis

The key is to paste the link and attach a purpose. Memorize three patterns. First, attach "in 3 lines" and "as an outline" to "summarize" to control the length. Second, pull out the practical version with "extract 5 benchmarking points." Third, dig into a section with "explain in detail from the 10-minute mark." Videos without subtitles have lower recognition rates, and for videos over 2 hours, ask about the first half and second half separately. Pass the summary result into NotebookLM and it becomes Q&A material.

Gems (Custom Assistants)

The order for building one is naming, role definition, tone, and fixing the output format. An example:

Name: YouTube Planner
Role: An expert who drafts plans for videos with 100,000+ views
Tone: Firm and concise
Output format: 5 title candidates, an outline, a script for the first 30 seconds

Upload reference material with the knowledge button and it prioritizes that scope. Upload a channel analysis report and it matches your channel's tone. Gems are better when you dig deep into one. Two, a planning one and a research one, give better results than a single all-purpose Gem. A Gem that works well can be shared with friends via a link.

NotebookLM Integration

There is an order. Upload the material first, skim the whole thing with an audio overview, then dig in with chat. For a contract review, narrow the scope like "gather only the penalty clauses in this contract." For a paper, point to a location like "explain the figures in Table 3." It says it doesn't know what isn't there, so use it with confidence. Note that scanned PDFs need text recognition first. If the letters are broken, the answers are broken too. Upload meeting minutes split by date and time-series questions become possible. Requests like "gather what was decided in last quarter's meetings" work.

Scheduled Tasks

Put the time, repeat cycle, and content into one sentence. Like "summarize 5 IT news items every Monday at 9 a.m." For a daily to-do checklist, setting the time for the night before is good. You can toggle scheduled tasks on and off in settings, so set them without worrying. If no result arrives, check the notification inside the Gemini app first, not the spam folder. There is a maximum number of schedules, so delete the ones you don't use.

Making Music

Put the genre, mood, length, and purpose into one sentence. Like "a calm acoustic BGM of 1 minute for a cafe video." If you need lyrics, give the topic and language together, like "a K-pop style birthday song for a child." Treat the first result as a sketch, and when a direction you like emerges, pick with "make 3 more in the same style." For video use, make a 5-second intro and a 1-minute main version separately. It is cleaner than stitching them together.

Automatic File Generation

Do not end the conversation as text. One line like "make the above into Excel" produces a table file. There are three tips. First, define the table headers in advance, like "make a table with date, item, and amount." Second, if you have a company template, upload the template file along with it. Third, for a report, scan for typos on screen before receiving it as PDF. Fixing it after you receive the PDF means starting over. For a list, receiving it as CSV and opening it in Excel keeps the letters from breaking.

4. Recommended Learning Order

If you are new, finish turning on memory, app integration, and pre-entering your requests first. Then build one Gem and one NotebookLM and run them daily. Once you are comfortable, add Deep Research and scheduled tasks. Follow this order and within a week you'll feel like you hired an assistant.
