Why AI suddenly seems to be everywhere
Four things changed at once: AI learnt to talk, got far cheaper and better, and moved into apps you already use. Here’s what that means for you.
Video transcript
Your email offers to write replies. Your search results come with summaries. So why is AI suddenly everywhere? It comes down to four changes.
The first change: you can just chat with it. AI had worked quietly in the background for years. Then, in late 2022, ChatGPT let anyone ask for help in everyday words.
Word spread fast. ChatGPT reached an estimated 100 million users in two months. TikTok took about nine months, and Instagram about two and a half years.
Second, it got far cheaper. Using an AI as good as the early ChatGPT became more than 280 times cheaper in under two years, so companies could offer it to millions.
Third, it got better. Today’s assistants follow instructions more closely, and they can see and hear too. Show one a photo, upload a document or just talk to it.
Fourth, it moved into apps you already use. Your phone, your email, your work software and your search engine now come with AI built in.
Businesses moved fast too. 78 per cent of organisations said they used AI in 2024, up from 55 per cent the year before.
You don’t need to be technical to use it, but do check anything that matters. Read the full guide below, and try spotting the AI in your own apps.
In 30 seconds
- AI learnt to talk: a simple chat window meant anyone could use it, with no technical skills.
- It got far cheaper and better, so companies are building it into apps you already use.
- You don’t need to be an expert, but knowing the basics helps you use it well and safely.
Open your email and there’s a button offering to write your reply. Search for a recipe and an AI summary sits above the links. A few years ago, AI was something you read about in the news. Now it seems to be built into everything. So what changed?
It learnt to talk
AI isn’t new. It has filtered spam and recommended songs for years, mostly out of sight. What changed in November 2022 was ChatGPT: an Jargon busterAI assistant: A chat app such as ChatGPT, Claude or Gemini that answers questions and does tasks you describe in plain language. anyone could use, just by typing into a chat window in everyday words.
It was also Jargon busterGenerative AI: AI that creates new text, images, sound or video, rather than only sorting or labelling things.. Instead of quietly sorting things, it wrote new things, from birthday poems to cover letters, in seconds. Word spread fast.

It got far cheaper, and better
cheaper: the cost of using an AI model as good as GPT-3.5, the kind behind the first ChatGPT, fell more than 280-fold between November 2022 and October 2024.
Source: Stanford HAI, AI Index Report 2025, April 2025Every answer an AI gives costs money to produce, in computing power and electricity. As that cost tumbled, companies could afford to offer AI to millions of people and build it into everyday apps.
The answers improved too. Today’s assistants follow instructions more closely, cope with much longer documents and can work through a problem step by step. Most are also Jargon busterMultimodal: An AI that understands more than one kind of input, such as text, pictures, sound and video.: snap a photo of a plant with yellowing leaves and ask what it needs, or talk to it out loud while you cook.
It moved into apps you already use
You no longer have to go looking for AI. It’s being built into the things you open every day, so you often meet it without choosing to.
- Your phoneAssistants you can talk to, tools that tidy up photos, and suggestions as you type.
- EmailSuggested replies, drafts written for you and summaries of long threads.
- Office softwareHelp drafting documents, building slides and summarising video calls.
- SearchAI-written answers above the usual links. Handy, but worth checking.
Businesses moved fast, too. Stanford’s AI Index found 78% of organisations said they used AI in 2024, up from 55% a year earlier. And it’s not just work: Ofcom found 54% of UK adults say they use AI tools, up from 31% the year before.
What it means for you
You don’t need to be technical to benefit. If you can send a text message, you can ask AI to explain a letter, draft an email or plan a trip. New to all this? What is AI? covers the basics.
- Try it on purpose. Give it one real job this week. Five things to try is a good start.
- Use the buttons when they help. You don’t have to accept every suggestion your apps make.
- Keep your judgement. AI can sound sure and still be wrong, so check anything that matters. Here’s why it happens.
Try it yourself 5 minutes
- Open your email, your phone’s photo app and a search engine.
- Look for AI features: buttons offering to write, summarise or edit, often marked with a sparkle symbol.
- Try one on something low-stakes, such as summarising a long newsletter.
- Ask yourself: did it save you time, and was it right?
