ChatGPT, Claude or Gemini? Which AI assistant to use now
All three got big upgrades in September. Here is what changed, what each one is best at, and how to pick the right one for you without paying for all three.
By Manish
If you have tried to choose an AI assistant lately, you have probably felt a bit lost. ChatGPT, Claude and Gemini all released new versions in September 2026, within a few weeks of each other. Each company says its new model is faster, smarter or cheaper. And all three look almost the same when you open them: a box where you type, and an answer that appears.
So which one should you use? The honest answer is that all three are very good now. The difference is less about which one is “smartest” and more about which one fits the way you work. This guide explains what changed, what each assistant is best at, and a simple way to test them yourself before you spend any money.
The quick answer
If you only read one part of this post, read this:
- Pick ChatGPT if you want one tool that does a bit of everything: chat, pictures, voice and help with everyday tasks. It is the most widely used, so it is also the easiest to find help for.
- Pick Claude if most of your work is writing, editing or reading long documents. Many people find its writing sounds more natural, and it is strong at helping with code.
- Pick Gemini if you already live in Google: Gmail, Google Docs, Drive and Calendar. It works inside those apps, which saves you copying and pasting.
- Not sure? Start with the free version of two of them, try the same three tasks in each, and keep the one you like. More on that below.
| ChatGPT | Claude | Gemini | |
|---|---|---|---|
| Made by | OpenAI | Anthropic | |
| Free plan | Yes | Yes | Yes |
| Standard paid plan (US) | $20 a month | $20 a month | $19.99 a month |
| Newest model (Sept 2026) | GPT-6 Sol | Claude Opus 5.5 and Sonnet 5.5 | Gemini 3.8 Flash |
| Best for | Everyday all-round help, pictures, voice | Writing, long documents, coding | Working inside Gmail, Docs and Drive |
What changed in September
September was a busy month. Here is what happened, in plain words.
On 2 September, Google released Gemini 3.8 Flash. Flash is Google’s fast, low-cost model for everyday jobs. It can read text, pictures, sound, video and PDF files, and Google says it does better than the version before it at the same price.
On 22 September, two big releases landed on the same day. OpenAI launched GPT-6 Sol and GPT-6 Luna. Sol is built for everyday work, writing and coding. Luna is a smaller, very cheap version. OpenAI cut the price of both to about half of what the models they replace cost. That price is for developers who build apps on top of OpenAI, but it also tends to mean more features for regular users over time.
Also on 22 September, Anthropic released Claude Opus 5.5, its most powerful everyday model. Anthropic says it does most work about as well as its very top model, runs more than 30% faster, and costs 40% less to run than the model before it. Six days later, on 28 September, came Claude Sonnet 5.5. That is the middle model most people use day to day. It kept the same price and got faster.
Finally, on 29 September, OpenAI announced “dots”. These are AI helpers inside ChatGPT that keep working on a job in the background, even when you log off. For now they are only for people on higher paid business plans, so most readers will not see them yet.
The big picture: each new model is both better and cheaper than the last. If you tried one of these tools a year ago and gave up, it is worth trying again.
What they cost
Good news first: all three have a free plan. You can use ChatGPT, Claude and Gemini without paying anything. The free plans have limits. You can only send a certain number of messages, and you may not get the newest model all the time. But for light use, the free plans are often enough.
If you want more, the standard paid plan for each one costs about the same: around $20 a month in the United States. ChatGPT Plus is $20, Claude Pro is $20, and Google AI Pro is $19.99. Google’s plan also comes with extra cloud storage, which is useful if you already pay Google for storage.
Two warnings about prices. First, they change often, and they are different in each country. In the UK, for example, tax pushes the price up. Second, all three companies also sell much more expensive plans for heavy users. You almost certainly do not need those to start. Always check the official price page before you pay. If you want to save, our guide to paying less for AI has eight simple ways.
ChatGPT: the all-rounder
ChatGPT is the AI assistant most people have heard of, and for good reason. It does a little of everything. You can chat with it, ask it to explain something, have it draft an email, make a picture, or talk to it out loud with your voice.
Because so many people use it, there are thousands of guides, videos and tips online. If you get stuck, someone has probably already answered your question. That makes it a friendly first choice.
Where it is strongest: everyday questions, brainstorming ideas, quick drafts, making images, and voice chat. Where to be careful: like every AI, it can sound very sure of itself even when it is wrong. Always check facts, dates and numbers that matter.
Claude: the writer and reader
Claude is made by a company called Anthropic. Many people who write a lot prefer it, because its answers often read more like a real person wrote them. It is also very good at reading long things: a big report, a contract, or a whole book chapter. You can paste in or upload a long document and ask questions about it.
It is popular with people who write code, too. Anthropic also makes [Claude Code](tool:Claude Code), a tool built just for programming.
Where it is strongest: writing and editing, summarising long documents, careful explanations, and coding. Where to be careful: its free plan has fairly tight daily limits, so heavy users may hit them quickly.
Gemini: the Google helper
Gemini is Google’s assistant. Its big advantage is that it is built into the Google apps many people already use every day. It can help you write in Google Docs, find things in Gmail, and work with files in Google Drive.
If your life already runs on Google, this saves a lot of copying and pasting between apps. The Flash models are also very fast, which is nice for quick questions.
Where it is strongest: anything inside Google’s apps, quick everyday questions, and working with pictures, video and files. Where to be careful: if you do not use Google’s apps much, you lose its biggest advantage.
Which one is right for you?
Here is a simple guide based on who you are and what you do most:
- Students: start with the free plans of ChatGPT and Gemini, and see our list of free AI tools for students. If you write long essays, try Claude for editing. Check your school’s rules about AI first.
- Writers and bloggers: try Claude first. Many writers find it needs less fixing afterwards.
- Small business owners: Gemini if your business uses Google for email and documents; ChatGPT if you want one tool for many different jobs.
- People who write code: Claude is a strong choice, and ChatGPT is also very good. Try both on a real task.
- Busy parents and everyday users: ChatGPT is the easiest place to start, especially with voice chat.
Test them yourself in 15 minutes
Reviews can only tell you so much. The best way to choose is to try them on your own real tasks. It is free, and it takes about 15 minutes.
Pick three things you actually need help with. For example: write a short email to a customer, explain something you are confused about, and summarise a long article. Then do this:
- Open the free version of two or three assistants in different browser tabs.
- Give each one exactly the same request, word for word.
- Compare the answers. Which one needed the least fixing? Which one understood you best?
- Repeat with your other two tasks.
Most people find a clear favourite very quickly. You can also compare them side by side on Solthar: ChatGPT vs Claude, ChatGPT vs Gemini or Claude vs Gemini, with prices, good points and bad points in one place.
Do not pay for all three
It is easy to end up paying for several AI subscriptions without noticing. At about $20 each, three of them add up to around $60 a month, or $720 a year. For most people, one paid plan plus the free versions of the others is plenty.
A good rule: only pay for an assistant after you have hit its free limits several times in a week. That is a sign you really use it. If you are not hitting the limits, the free plan is doing the job.
A word on trust
All three assistants can make mistakes. Sometimes they make up facts, quotes or sources that do not exist, and they say them in a confident voice. This happens less than it used to, but it still happens.
So treat any AI answer as a helpful first draft, not the final word. Check anything important, such as health, money, legal or school facts, against a trusted source. And do not paste in private information, like passwords or bank details, that you would not want stored.
The bottom line
There is no single “best” AI assistant in late 2026. ChatGPT is the friendliest all-rounder. Claude is a favourite for writing and long documents. Gemini is the natural choice if you live in Google’s apps. All three have free plans, and the paid plans cost about the same. Try two of them on your own tasks this week, keep the one that fits, and only pay when the free version starts holding you back.
