ChatGPT, Claude, Gemini Plans: Four Things to Check Before You Pay
The time to subscribe is when free usage runs out, or when the feature you need only exists behind a paywall. Here are the criteria to weigh before you even look at the price tags for ChatGPT, Claude, and Gemini.
A paid AI plan is worth considering at one of two moments: when your free usage runs out, or when the feature you need is locked behind a subscription. Start by writing down where you actually get stuck. Then look at the cheapest plan that solves that specific problem, and the decision gets much simpler.
What are you actually paying for?
It helps to think of AI plans the way you think of mobile phone plans. If your everyday usage is light, you will not use up all the headroom that a bigger plan gives you. On the other hand, if you keep hitting limits, the extra capacity alone can justify the payment. Beyond capacity, you also need to check whether the plan includes the specific features you need.
The three services bundle higher usage and extra features in different ways. ChatGPT Go raises the limits on file uploads, image generation, and tool use. Claude Pro increases usage limits, gives you access to more models, and includes Claude Code. Google’s AI plans bundle Gemini app usage together with things like cloud storage. So before you even look at the price tags, decide which of these you actually need: working with files, generating images, coding, or storage.
What to check before you pay
First, write down the tasks you do with AI over and over. Be specific: are you uploading files to review their contents, generating images, or using it for coding? This is far more useful than a vague “I want to use AI better,” because it narrows down which features matter.
Second, note the moments when the free tier frustrated you. Distinguish between running out of usage and not having the model or feature you wanted. If it is the former, limits are your comparison point. If it is the latter, the question is whether the plan includes that feature at all.
Third, verify those conditions on the plans you are considering. On the signup screen, look again at the amount that will actually be charged and the features you will actually get. The prices and limits below are as of September 2026. Be especially careful not to treat a price listed in dollars as the final amount you will pay in Korea.
How do the three services differ?
Here are the plans a newcomer is most likely to compare first.
| Service and plan | Price | Difference to look at |
|---|---|---|
| ChatGPT Go | $8 per month in the US | Higher limits than free for file uploads, image generation, and tool use |
| ChatGPT Plus | $20 per month | Access to models that think longer before answering, plus wider limits on messages, file uploads, and deep research |
| Claude Pro | $20 per month, $200 per year | At least 5x the free tier’s usage per 5-hour window, plus more models and Claude Code |
| Google AI Plus | 7,500 won per month | 2x the free tier’s Gemini app usage, with 400GB of storage |
With ChatGPT, the question is whether you simply need higher limits for file and image work, or whether you also need the models and deep research included in Plus. Claude Pro enters the comparison if you need a wider range of models or Claude Code. Monthly and annual billing take very different amounts out of your account at once, so factor in how long you expect to keep using the service.
For Gemini, it makes sense to weigh AI usage and storage together. Google AI Plus raises storage from the free 15GB to 400GB. Google AI Pro offers 4x the free tier’s usage limits and includes 5TB of storage along with Gemini inside Gmail and Docs. If you want to use Gemini in your documents and email, this feature may be a factor in choosing a plan.
When should you look at the expensive plans?
Even when you move up the ladder, the first thing to check is still your own usage. ChatGPT Pro’s $100 per month plan offers 5x the usage of Plus. The $200 per month plan offers 20x, but as of September 10, new signups and upgrades to it have been temporarily suspended.
Claude Max is split into $100 and $200 per month tiers, offering 5x and 20x Pro’s usage respectively. Google AI Ultra starts at 119,000 won per month on Google’s official Korean page, with a higher option listed at 300,000 won per month. Their usage limits are 5x and 20x Pro’s, respectively.
The same “5x” does not mean the same thing
This is where you can go wrong: comparing services by the multiplier alone. Claude Pro’s multiplier is measured against the free tier, while Max’s is measured against Pro. Google AI Plus and Pro are measured against the free tier, while Ultra is measured against Pro. Multipliers are only useful for reading how much a plan increases over another plan within the same service.
What will you actually pay in Korea?
The currency on the screen and the amount that leaves your account can be different things. As of September 2026, ChatGPT supports billing in Korean won. But Go’s $8 per month is the US price. Do not treat it as what you will pay in Korea; check the amount on the signup screen.
Claude’s listed prices exclude tax. Do not budget based on the $20 figure alone. Look at the total including tax at the checkout stage. Gemini’s Korean plans are quoted in won, as shown above. Because each service presents its pricing differently, avoid simply picking whichever number looks smaller.
Four things to check before you pay
- Have you written down, specifically, the tasks you repeat and the features you need?
- Have you identified whether the free tier fell short on usage or on features?
- Have you checked what baseline each limit multiplier is measured against?
- Have you re-checked the final amount and the available features on the signup screen?
The value of a paid plan lies in securing the features and capacity your work actually requires. Start with the plan that solves the problem you have right now, then come back later and compare what you actually used against what you paid. Even when you look at pricier plans, the starting point is not the big multiplier but what you personally are missing.
