The AI model Google answers ChatGPT and Claude with - except instead of a separate app, it simply disappears into your phone, your inbox, and your search engine.
Technically Gemini is a family of models, not a single product. There's a version for quick chat in the browser, a version built into Android (the operating system most phones in the world run on, aside from iPhones), and a version for businesses through Google Cloud. The latest big release is called Gemini 3, and it's exactly this one that Google is pushing everywhere at once - from Gmail (Google's mail service) to search.
In practice it looks like this: you ask your inbox "who gave me a quote for the bathroom last year" and Gemini reads your emails and answers you in a plain sentence, not a link. On Android the model acts proactively - it books you a spin class ticket on its own, or finds the syllabus in an email and adds the required books to your cart. In May 2026 Google also launched "Gemini Spark" - an agent you literally email a task to, and it does it on its own through Chrome, while you watch the progress from your phone.
The reason Gemini exists is simple - Google has three billion phones, the most used search engine in the world, and all of your mail and documents. When ChatGPT showed that people want to ask AI directly instead of searching and clicking links, Google felt a threat to its own search engine. The answer wasn't a new app to download, it was the opposite - letting the AI-driven assistant disappear into the environment you already live in.
Here's Where the Real Thing Starts
There's no mystery here - the owner is Google, that is, Alphabet. But that's exactly why Gemini is a different case from ChatGPT or Claude. Gemini is built into your phone's operating system, into your mail, into your calendar. Turning it off means deciding to live without the core services you've used for years.
So for me the question isn't whether Gemini is a good model - it probably is. The question is who decides when it reads my mail and acts in my name, and whether I have any choice at all, once it's already there by default.
