Google Gemini is Google’s AI assistant and the family of AI models behind it. It is the chatbot at gemini.google.com, the assistant on most Android phones, the AI inside Gmail, Docs and Search, and the models developers call through the Gemini API.
One name covers all of them, which is why it confuses so many people.
This beginner-friendly guide explains what Google Gemini is in November 2026, which models it uses (Gemini 4 Argon, Carbon and Hydrogen), what it can do, what is free and what each paid plan adds, how to start using it on any device, how it compares with ChatGPT, and how to fix the most common problems.
- What it is: Google’s AI assistant (app and website) plus the Gemini AI models built by Google DeepMind.
- Latest models: Gemini 4 Argon (flagship, Oct 2026), Carbon (long agent tasks, Nov 2026) and Hydrogen (fast everyday model, Nov 12, 2026).
- Free? Yes. The free plan covers chat, Gemini Live voice, Canvas, Gems, image help and limited Deep Research.
- Paid plans: Google AI Plus $4.99, AI Pro $19.99 (adds Gemini 4 Argon and Gemini in Gmail/Docs), AI Ultra $99.99 or $199.99 (US prices).
- Where: gemini.google.com, the Gemini app on Android and iPhone, Chrome, Google Search, Workspace apps and the Gemini API.
- Start now: open gemini.google.com, sign in with a Google account and type a question.
What Google Gemini Means (App vs Model)
“Gemini” is used for two connected things:
| Gemini the assistant | Gemini the models | |
|---|---|---|
| What it is | An app and website where you chat, talk, upload files and create images | The large language models that power the app and other Google products |
| Who uses it | Everyone with a Google account | Google products and developers through the API |
| Where | gemini.google.com, Android, iPhone, Chrome | Gemini API, Google AI Studio, Google Cloud |
| Examples | “Summarise this PDF”, “Plan a trip”, Gemini Live voice chat | gemini-4-hydrogen, Gemini 4 Argon |
Gemini replaced the older Bard chatbot in early 2024 and has since taken over from Google Assistant as the main assistant on most Android phones. It is built by Google DeepMind, Google’s AI lab.
Gemini Models in November 2026
Google shipped three Gemini 4 models in about six weeks this autumn. Older Gemini 3.x models are still around in some places while the rollout finishes.
| Model | Released | Best for | Who gets it in the app |
|---|---|---|---|
| Gemini 4 Argon | October 13, 2026 | Hard reasoning, writing, analysis | AI Pro and AI Ultra |
| Gemini 4 Carbon | Early November 2026 | Long, multi-step agent work | Rolling out, mainly in agent tools |
| Gemini 4 Hydrogen | November 12, 2026 | Fast everyday chat, coding and agents | Everyone (free users via automatic model choice); also powers Google Search |
| Gemini 3.8 Flash | 2026 | Previous fast model | Being replaced by Hydrogen |
All of them understand text, images, audio, video and PDFs, and the API models have a context window of about one million tokens, enough for several long books at once. For deep dives, see our Gemini 4 Hydrogen guide.

Is Gemini Free? Plans and Prices
Yes, Gemini has a genuinely useful free plan. Paid plans are sold through Google One as “Google AI” plans. US monthly prices, checked in November 2026:
| Plan | Price | Main models | Usage | Extras |
|---|---|---|---|---|
| Free | $0 | Fast Flash-class / Hydrogen | Base allowance | 15 GB storage |
| Google AI Plus | $4.99 | Flash, more Gemini 3.1 Pro | About 2x Free | 400 GB, 200 Flow credits, family sharing |
| Google AI Pro | $19.99 | Gemini 4 Argon | About 4x Free | 5 TB, Gemini in Gmail/Docs, 1,000 Flow credits |
| Google AI Ultra | $99.99 or $199.99 | Argon, Deep Think | 5x or 20x AI Pro | Up to 30 TB, YouTube Premium, agents |
Usage is measured in compute rather than a fixed number of messages, and it refreshes every five hours up to a weekly cap. Prices vary by country, and students can often get AI Pro free for a year. Full details are in our Google AI Plus vs Pro vs Ultra comparison.
How to Start Using Gemini (Step by Step)
On a computer
- Go to gemini.google.com in any browser.

- Open it and sign in. Agree to make it your phone’s assistant if asked.
- Long-press the power button or say “Hey Google” to call Gemini from anywhere.
- Tap the Live button for a voice chat, and the camera icon to show it what you see.
On iPhone
- Install Google Gemini from the App Store. Check that the developer is Google LLC.
- Sign in with your Google account.
- Add the Gemini widget to your Lock Screen or Home Screen for quick access.
Good first prompts: “Summarise this PDF in five bullets”, “Write a polite reply to this email”, “Plan a 3-day trip to Jaipur on a budget”, or “Explain how this spreadsheet formula works”.
Where Else Gemini Shows Up
- Google Search: AI Overviews and AI Mode use Gemini, now Gemini 4 Hydrogen worldwide.
- Chrome: Gemini can read the page you are on and answer questions about it.
- Gmail, Docs, Sheets, Slides: drafting, summaries and formulas on AI Pro and up or business plans.
- Gemini Notebook (formerly NotebookLM): research notebooks built from your own sources. See our NotebookLM guide.

- Google Home and TVs: Gemini is replacing the older Assistant on many smart devices.
Gemini for Developers
Developers use the same models through the Gemini API and Google AI Studio, billed separately from consumer plans.

|---|---|
| Gemini 4 Hydrogen | $1.50 / $7.50 |
| Gemini 4 Argon | $2 / $10 until November 30, 2026, then $4 / $20 |
| Gemini 3.8 Flash | $0.75 / $3.75 until December 31, 2026, then $1.50 / $7.50 |
For coding agents, Google now points personal accounts to Antigravity, since Gemini CLI stopped serving personal accounts on June 18, 2026. See our Claude Code vs Gemini CLI comparison for how the tools differ.
Gemini vs ChatGPT vs Claude
| Gemini | ChatGPT | Claude | |
|---|---|---|---|
| Made by | OpenAI | Anthropic | |
| Main paid plan | $19.99 AI Pro | About $20 Plus | About $20 Pro |
| Biggest strength | Google app integration, storage bundle, Search | Huge feature set, Codex, GPTs | Writing and coding quality |

If you already live in Gmail, Drive and Android, Gemini is the most convenient. See our full ChatGPT vs Claude vs Gemini vs Grok comparison, and who owns ChatGPT if you are curious about the companies behind them.
Privacy: What Google Keeps
- Your chats are saved in Gemini Apps Activity by default. You can turn it off or set auto-delete in the Gemini settings.
- Google may use saved chats, including some reviewed by humans, to improve its products unless you turn activity off. Do not share passwords or private documents you would not want reviewed.
- Connected apps like Gmail are only used when you enable them, and you can disconnect them at any time.
- To clear history, follow our step-by-step guide to delete Gemini chats.
Troubleshooting
| Problem | Fix |
|---|---|
| “Gemini isn’t available” or the app won’t open | Check you are 13+ (18+ in some regions), signed in with a personal account, and in a supported country. Update the app. |
| Work or school account blocked | Your admin controls Gemini. Ask them to enable it or use a personal account. |
| Paid models not showing after you subscribed | Make sure you are signed in with the account that paid. Reload the app or sign out and back in. |
| “You’ve reached your limit” | Wait for the five-hour refresh, switch to a lighter model, or upgrade. |
| Gemini can’t see my Gmail or Drive | Open Settings, then Apps (connected apps), and turn on the Google apps you want. |
| “Hey Google” opens the old Assistant | In the Gemini app settings, set Gemini as your digital assistant. |
| Answers look wrong or outdated | Ask Gemini to search the web and show sources, or use Deep Research for important topics. Always check facts that matter. |
My Take
For most people, the free Gemini plan with Hydrogen is good enough for daily questions, writing and summaries, and Gemini Live is one of the best free voice assistants around.
If you also want Gemini 4 Argon, Gemini inside Gmail and Docs, and 5 TB of storage, AI Pro at $19.99 is the plan worth paying for.
Ultra only makes sense if you can name a specific Ultra-only feature, such as heavy video creation or agents.
