Most people pick an AI plan the way they pick a gym: they sign up for the big one, feel good for a week, then pay for it for a year while using a fraction of it. The whole game is matching the plan to what you actually do, not to the feature list. So here is the landscape first, plainly, then a prompt that makes the call for your own usage.
The AI plan worth paying for is the one that matches what you actually use each week, not the highest tier on the pricing page.
Every main AI plan, side by side
Prices pulled from each provider's official page on 7 September 2026, in US dollars per month. Prices and tier names change often and vary by country, so treat this as a snapshot and check the provider's page before you buy.
| Tool | Free | Everyday paid tier | Power tier | Best for |
|---|---|---|---|---|
| ChatGPT (OpenAI) | Yes | Go $8, Plus $20 | Pro $100 | The all-rounder and biggest app ecosystem |
| Claude (Anthropic) | Yes | Pro $17 | Max from $100 | Writing, long documents, careful reasoning |
| Gemini (Google) | Yes | AI Pro $19.99 | AI Ultra from $99.99 | Living inside Google apps, plus big storage |
| Perplexity | Yes | Pro $17 | Max $167 | Research with sources and citations |
| Grok (xAI) | Yes | SuperGrok $29.99 | Heavy $49.99 | Real-time answers and anything on X |
| Copilot (Microsoft) | Yes | Pro (check the page) | — | Working inside Word, Excel and Outlook all day |
One honest note on that table before you read a price as gospel: Copilot's public pricing page would not load cleanly when I pulled the rest, so I have left its paid figure as "check the page" rather than quote a number I could not verify today. That is the rule for this whole guide, a real price or none.
Which one is for you, in a line each
- ChatGPT if you want one tool that does a bit of everything. It has the widest set of features and the biggest app and plugin ecosystem, so it is the safe first pick if you do not yet know what you will lean on most.
- Claude if your work is mostly words. It is the tidiest writer and the best at long documents and staying careful over a long reasoning task, which is why a lot of people who write for a living keep it open.
- Gemini if you live in Google. It sits inside Docs, Gmail and the rest, so the win is not a cleverer model, it is AI in the tools you already use all day, plus a big chunk of storage bundled in.
- Perplexity if you mostly want answers you can trust. It is built as an answer engine that shows its sources, so it is the one to pay for if your real job is research and you need to see where a claim came from.
- Grok if you are on X and want it now. Its edge is real-time access to what is being posted this minute and a looser style, so it fits news, reactions, and anything happening live.
- Copilot if your day is Microsoft 365. If you are in Word, Excel and Outlook from nine to five, the value is AI baked into those, not a separate chat window you have to switch to.
How to tell if you should pay at all
- Start from what you do, not the features. Write down the last five things you actually asked an AI to do, because you pay for the whole tier but only ever use a slice of it, and the slice is what should decide the plan.
- Treat the free tier as the real baseline. Run a normal week on the free version first, because for light or occasional use it is often enough, and the paid plan only earns its money once the free one keeps stopping you.
- Know what the roughly-twenty-a-month tier is actually for. On most tools it buys higher limits and the smarter model, not a different product, so it is worth it only if you hit the free ceiling often. A rate limit is just the tool saying "that is enough for now, come back later", and if you never see that message you are not being held back.
- Leave the hundred-plus power tiers for genuinely heavy days. Those plans are built for people in the tool for hours daily, so unless that is you, you are paying a premium for headroom you will never reach.
- Stop stacking plans that do the same job. Pick the one tool you reach for first and cancel the overlapping second, because most people quietly pay for two or three AI tools that all write, summarise and answer, then only ever open one.
The thing running under all of it: most people are not underpowered, they are overpaying for a tier they barely use. The question is never "which AI is best", it is "which plan matches my actual week".
The prompt that decides it for your usage
The table tells you the landscape. This prompt tells you your answer. Paste it into a new chat with any AI tool, or save it as a skill, which just means keeping the file so it is there next time you are weighing up a tool. It asks a few plain questions, then gives you a straight free, paid, or cancel call with the reason.
You are a plain-spoken advisor helping me decide whether an AI subscription is worth the money for how I actually use it. You are not a salesperson and you do not push me toward the paid option. Talk like a smart friend, not a pricing page. Ask me these questions ONE at a time, wait for my answer to each before asking the next, and keep them simple: 1. Which AI tool or tools are you paying for or thinking of paying for right now? 2. What are the last few real things you used AI for? Give me actual examples, not categories. 3. How often do you use it: a few times a month, a few times a week, or most days? 4. When you use the free version, do you ever hit a wall (it slows down, cuts you off, or says you have reached a limit)? How often? 5. Is there one specific paid feature you know you need (for example longer documents, image generation, voice, or a particular newer model)? If you are not sure, say so. Once you have my answers, give me a clear recommendation in this shape: - The call: STAY FREE, PAY FOR ONE TIER UP, or CANCEL / DON'T SUBSCRIBE. Say which, in the first line. - Why, in two or three plain sentences tied to MY answers, not general claims. - What I would be paying for that I probably will not use, named specifically, so I can see the waste. - If I am paying for more than one tool, which single one to keep and which to drop, and why. - One thing to try for a week before deciding, if my answers were not clear enough to call it. Hard rules: - Do NOT state current prices, tier names, or model names as fact. They change often and vary by country. If a price matters to the decision, tell me to check the tool's own pricing page and give me the question to answer there, rather than quoting a figure. - Never invent a benchmark, a statistic, or a claim that one tool beats another. If you do not know something for sure, say "check this yourself" and tell me where to look. - Base every part of the recommendation on what I actually told you. If my answers are too thin to decide, say so and ask for the one more thing you need, rather than guessing. - Do not upsell. If the honest answer is that the free tier is enough for me, say that plainly.
Where the line is
- The honest bit: prices move, so this is a snapshot, not a live feed. Every figure here was pulled from the provider's own page on 7 September 2026, and the one I could not verify is marked "check the page". Always confirm on the official page before you pay.
- The prompt is only as good as your answers. Undercount how often you really lean on the tool and it will tell you to stay free when paying would genuinely help. Treat it as a way to see your own usage clearly, not as financial advice. You stay the one who decides.
Set it up once
Read the table for the lay of the land, then run the prompt on the one tool you are actually paying for or tempted by. Ten minutes, and you will know whether this month's payment is buying you anything. Do it once and it pays for itself the first time it talks you out of a plan you were not using.
If you want the short version first, the reel for this walks through the free-versus-paid call in under a minute. Comment WORTH on the post and I will send you this exact prompt.
