Overview

Gemini is an artificial intelligence assistant developed by Google. It allows users to interact in natural language to write, research information, learn, analyze documents, generate content, and support creative or technical projects.

The assistant can process different types of content, including text, images, PDF files, spreadsheets, videos, and codebases. It can also use recent information from the Web and work with several Google services when authorized by the user.

Gemini is available through a web browser, on Android, iPhone, and iPad, in Google Chrome, and through an official macOS application. Available features vary depending on the device, country, language, age, account type, and subscription.

Its integration with the Google ecosystem is one of its main distinguishing features. Gemini can notably work with Gmail, Google Drive, Docs, Calendar, Tasks, Keep, Maps, YouTube, and other compatible applications.

Features

Conversation and writing

  • Answer questions and explain complex concepts.
  • Write, correct, rephrase, or summarize text.
  • Translate and adapt content for different audiences.

  • Organize and summarize data.
  • Generate tables, charts, and explanations.
  • Examine code files or compatible repositories.

Gemini can work with large amounts of content, but upload and context limits vary depending on the model and subscription.

Gemini Live

Gemini Live allows users to interact verbally with the assistant in a more natural way. Users can interrupt a response, change the subject, or add details during the conversation.

On compatible devices, Gemini Live can also use:

  • the camera;
  • images;
  • screen sharing;
  • content displayed on the screen;
  • certain connected applications.

This feature can be used to obtain an explanation while looking at an object, analyze an interface, think aloud, or request assistance during a task.

Image generation and editing

  • Generate images from a description.
  • Modify an existing image.
  • Add, replace, or remove certain elements.
  • Create visual variations.
  • Combine text with visual references.
  • Produce illustrations for a project or presentation.

Available models, limits, and usage rules may vary depending on the subscription and country.

Video and other creative content

Depending on the plan and availability, Gemini may provide access to video generation or editing features, as well as other creative tools from Google.

Some features rely on complementary products such as Google Flow. They should not be confused with all the features available for free inside the Gemini application.

Canvas

Canvas provides a separate workspace for developing and editing longer content.

It can notably be used to:

  • write and revise a document;
  • create a presentation;
  • work on code;
  • generate a web page;
  • design a prototype;
  • preview a result as it develops;
  • modify a deliverable without losing the context of the conversation.

Gems

Gems are customized assistants configured for a particular use.

Users can define:

  • their role;
  • their instructions;
  • how they should respond;
  • the tasks they should prioritize;
  • certain reference files.

A Gem can, for example, become a writing assistant, teacher, creative partner, or specialized adviser for a project.

Connected applications

Gemini can connect to several services to retrieve information or complete certain actions.

Depending on the permissions granted, it can notably:

  • search for information in Gmail;
  • access files in Google Drive;
  • use Google Docs documents;
  • create or retrieve events in Google Calendar;
  • manage tasks and reminders;
  • access notes in Google Keep;
  • use Maps, YouTube, or other compatible services.

Available applications depend on the device, country, language, and account type.

Gemini in Chrome

Gemini can be used directly inside Google Chrome to provide assistance while browsing.

It can notably:

  • summarize a page;
  • explain a concept;
  • compare content from several tabs;
  • answer questions about the current page;
  • use Gemini Live while browsing;
  • complete certain multi-step tasks when agentic features are available.

Users should review the tabs being shared and the permissions granted to Gemini.

macOS application

Google offers a dedicated Gemini application for macOS. It provides access to the assistant from the desktop without relying exclusively on a browser tab.

The availability of certain features may differ from the Web or mobile versions and may depend on the installed version of macOS.

Software development

  • Explain code.
  • Generate or correct functions.
  • Identify errors.
  • Analyze files and repositories.
  • Produce tests and documentation.
  • Create prototypes in Canvas.
  • Compare several technical approaches.

Google also offers other development tools based on Gemini, but these are complementary products and are not all integrated directly into the consumer application.

Learning

  • Explain a concept step by step.
  • Create a study plan.
  • Summarize a course or document.
  • Generate exercises and quizzes.
  • Adapt an explanation to the user's level.
  • Turn complex content into a more accessible summary.

Use cases

Writing and communication

Gemini can prepare an outline, write a message, correct text, summarize a document, or adapt content to several formats. Its integration with Google Workspace is particularly useful for people who already work with Gmail, Docs, and Drive.

Research and monitoring

The assistant can research recent information, compare sources, and produce a report with Deep Research. It can support editorial monitoring, a study, or the preparation of an article.

Document analysis

Gemini can extract information from PDF files, compare several documents, and build a synthesis. It is suitable for projects containing numerous documents or reference data.

Visual creation

The tool can generate or edit images, prepare an artistic direction, suggest variations, and support the design of a visual or prototype.

Development

Gemini can explain a codebase, suggest an implementation, detect errors, and produce tests. Canvas can also be used to create and preview certain prototypes directly from the conversation.

Personal organization

Through connected applications, Gemini can retrieve information from Gmail or Drive, check a calendar, prepare an itinerary, organize tasks, or use data from several Google services.

Learning and training

Gemini can transform a course into a summary, explain a concept, generate exercises, or prepare a revision program adapted to a specific objective.

PANACHES review

Gemini stands out above all for its deep integration with the Google ecosystem. It becomes particularly useful for people who already work with Gmail, Drive, Docs, Calendar, Chrome, Maps, or YouTube.

This continuity makes it easier to move from a question to a concrete action, such as finding a document, summarizing messages, organizing an appointment, or working with several sources. Gemini also combines research, visual creation, file analysis, and educational tools within a single interface.

Its value is less obvious for people who want to remain independent from Google services or strongly limit data sharing between applications. The power of its integrations therefore comes with a genuine need to review permissions and privacy settings carefully.

Like other generative assistants, Gemini should be used as an assistance tool rather than as an automatically reliable source.

Points to consider

  • Gemini can produce incorrect, incomplete, or fabricated answers.
  • Important information should be verified against the original sources.
  • Models, features, and usage limits may change rapidly.
  • Certain features require a paid subscription.
  • Availability depends on the country, language, age, device, and account type.
  • Connected applications may provide access to authorized emails, files, events, photos, or other content.
  • Connected applications and their permissions should be reviewed regularly.
  • Conversations, files, images, voice recordings, or screen sharing data may be retained according to the account's activity settings.
  • Retention periods and deletion options depend on Google's settings and policies.
  • Certain data may be shared with other Google services or third-party services when required to complete a request.
  • Gemini in Chrome may use the content of shared tabs to produce its answers.
  • Agentic features should be supervised when they browse or perform actions on the Web.
  • Gemini is a proprietary service dependent on Google's infrastructure and ecosystem.
  • A fluent answer or one supported by references is not necessarily accurate.
  • Gemini is not a substitute for a qualified professional when making important medical, legal, or financial decisions.
