Gemini is Google’s AI assistant and the name of its family of models. You meet it in the Gemini app and website, inside Gmail, Docs and other Google products, and as a developer platform. Google sells paid access through its Google AI plans, which bundle Gemini usage with storage and, on some tiers, extras such as YouTube Premium.
This review covers what Google documents about the plans, how usage limits work, what recent release notes show about where the product is heading, and how Google describes data handling for personal accounts. It is written for people deciding whether Gemini or another assistant fits how they work, especially if they already live in Google’s apps.
How we researched this: we did not run hands-on tests for this article. It is based on the vendor’s own documentation and public sources, checked on 11 November 2026. Features and prices change, so confirm details on the vendor’s site before you buy.
Key takeaways
- Google’s UK plans page lists Free, Google AI Plus (GBP 4.49 a month), Google AI Pro (GBP 18.99) and Google AI Ultra (from GBP 79.99, up to GBP 189.99). In the US, Google announced at I/O on 19 May 2026 a new $100 Ultra tier and a cut in the top Ultra tier from $250 to $200.
- Limits are compute-based. Google says they depend on prompt complexity, features used and chat length, refresh every five hours until you reach a weekly limit, and can be extended by buying AI credits.
- Google’s release notes show quick change: Skills arriving in chat on 30 September 2026 with a plan to replace Gems, and Gemini 4 Argon rolling out to Pro and Ultra on 13 October 2026.
- With Keep Activity on, Google says your activity can be used to improve its services, including training generative AI models. Some chats are reviewed by humans and kept for up to three years, disconnected from your account.
- Work and school accounts have different data terms, and Google points to a separate Workspace privacy hub for them.
What it is
Gemini is both a set of models and the apps built on them. Google’s plans page describes a Gemini app with image generation and editing, Deep Research, Gemini Live, Canvas, Gems and a notebook feature, plus access to developer tools such as Google AI Studio and Google Antigravity. A business edition, Gemini Enterprise, is sold separately.
The models are large language models, which can produce confident but wrong answers. See what is a large language model for the basics.
Recent changes from Google’s release notes
| Date | What Google’s release notes say |
|---|---|
| 21 July 2026 | Gemini 3.6 Flash, an upgraded Flash model for everyday tasks, becomes available to all Gemini app users |
| 29 July 2026 | Voice dictation comes to the Gemini macOS app |
| 19 August 2026 | Student hub and study notebooks on mobile, with free Google AI Pro for one year in the US or AI Plus in 140 or more countries for eligible college students |
| 10 September 2026 | The Gemini app launches on Windows, summoned with Alt and Space |
| 30 September 2026 | Skills arrive in Gemini chat for saving reusable instructions; Google says they will eventually replace Gems, with existing Gems migrating automatically |
| 13 October 2026 | Gemini 4 Argon rolls out to Google AI Pro and Ultra subscribers; Antigravity comes to the macOS app; a Customize menu connects 40 or more apps |
These changes matter for buyers because model names and features differ across the pages we read. For example, Google’s May announcement refers to Gemini Omni and Gemini 3.5 Flash being added to paid plans, while its current plans page names Gemini 4 Argon and Gemini 4 Carbon. Read the live page for what your plan includes.
Who it is for
- People who already use Google apps. The plans bundle storage, Gemini in Gmail, Docs and Vids, and, on some plans, YouTube Premium Lite or YouTube Premium.
- Students. Google’s release notes describe free access offers for eligible college students.
- Heavy users and developers. The higher tiers advertise multiples of Pro usage and Antigravity limits.
- Businesses. Gemini Enterprise Business is listed from $21 per seat per month for up to 300 seats, and Standard and Plus editions from $30 per seat per month with unlimited seats.
If your files and email are not in Google’s ecosystem, much of the bundle value disappears and a standalone assistant may be a better fit. See the ChatGPT review and Claude review.

Google says the $200 tier was reduced from $250 and offers the same capabilities as before. The articles we read did not state the US prices for AI Plus and AI Pro, so we do not give them.
Pricing model
Checked on 11 November 2026. The UK table below is in pounds from Google’s plans page. Prices differ by country, so confirm yours.
| Plan | UK price per month | Usage | Storage |
|---|---|---|---|
| Free | GBP 0 | Baseline | 15 GB |
| Google AI Plus | GBP 4.49 | 2x Free | 400 GB |
| Google AI Pro | GBP 18.99 | 4x Free | 5 TB |
| Google AI Ultra | GBP 79.99 or GBP 189.99 | 5x or 20x Pro | From 20 TB |
Business and developer options

|---|---|
| Gemini Enterprise Business | From $21 per seat per month, up to 300 seats |
| Gemini Enterprise Standard and Plus | From $30 per seat per month, unlimited seats |
| Google AI Studio | Free to start; paid plans for higher rate limits |
| Google Antigravity | Free to start with basic weekly limits; paid plans for more |
| Gemini platform | Pay as you go |
Google says paid access is available in 150 or more countries (Plus in 160 or more), and that some benefits require users to be 18 or older. Bundles make comparison harder, because part of what you pay buys storage and video services. Our guide on how to read an AI tool’s pricing page explains how to separate them.
Strengths
- Integration with Google apps. Gemini in Gmail, Docs and Vids is listed on paid plans.
- Bundle value. Storage and YouTube plans are packaged in, if you would buy them anyway.
- Generous free tier. The Free plan lists Deep Research, Gemini Live, Canvas and Gems.
- Frequent updates. Release notes show monthly additions across mobile and desktop apps.
- Clear privacy hub. Google publishes retention periods and a human review description for personal accounts.
Limits and cautions
| Caution | Detail |
|---|---|
| Compute-based limits | Limits depend on prompt complexity, features and chat length, so you cannot count prompts. They refresh every five hours up to a weekly limit. |
| Regional differences | Several features, such as Gemini Spark and AI Inbox in Gmail, were described as US only. Prices and features vary by country. |
| Moving names | Models, tiers and features such as Gems versus Skills change often. |
| Premium features gated | Project Genie is described as Ultra only, and some features require users to be 18 or older. |
| Errors | As with any assistant, answers can be wrong. See how to check AI output for mistakes. |
Privacy and data
Google’s Gemini Apps Privacy Hub describes how personal-account chats are handled.
| Topic | What Google says |
|---|---|
| Keep Activity on | Chats and uploads are saved to Gemini Apps Activity, which you can review and delete. Activity is used to improve Google services, including training generative AI models. |
| Keep Activity off | Future chats do not appear in Activity but are kept for 72 hours so Gemini can respond. They are not used for training unless you send feedback. |
| Temporary chats | Kept for 72 hours and not used to train Google’s AI models. |
| Auto-delete | Activity auto-deletes after 18 months by default. You can change this to 3 or 36 months or turn auto-delete off. |
| Human review | A subset of chats is reviewed by human reviewers, including trained service providers. Reviewed chats are disconnected from your account and kept for up to three years, even if you delete your activity. |
| Ads | Google says Gemini Apps chats are not being used to show you ads. |
Google adds that audio, Gemini Live video and screenshares are not used to improve services by default, and that settings do not control processing to create anonymised data. It also says Google still uses chats to respond to you and to protect users. The hub covers personal Google Accounts. Work or school accounts may be subject to different terms, which Google covers in a separate Workspace privacy hub that we did not review. Read how to protect company data when using AI tools before using a personal account for business content.

Who should and should not use it
Best for you if
- You use Gmail, Docs and Google storage daily and want AI built into them.
- You would benefit from the storage and video bundles on Pro or Ultra.
- You are a student who qualifies for the free offers, subject to Google’s eligibility rules.
Look elsewhere or take care if
- You do not use Google’s apps, so the bundle adds little.
- You need a firm commitment that chats are never reviewed or used for training, and are using a personal account.
- You want stable feature names and limits, since both are changing.
Questions to ask before buying
- What is the price in my country and which features are available there?
- Which model does my tier include today?
- Is Keep Activity on or off, and what auto-delete period do I want?
- Do I want the storage and YouTube extras, or am I paying for them without using them?
- Will I hit the five-hour or weekly limit, and would AI credits cover it?
- For work use, does my organisation need a Workspace or Enterprise plan with different terms?

Conclusion
Gemini’s documented strength is its fit with Google’s apps and bundles. The cautions are compute-based limits, regional differences, fast-moving model and feature names, and a personal-account data policy that includes training and human review unless you change settings.
