AI is a genuinely useful assistant and a genuinely noisy market β every week there is a new tool, a bigger claim and another subscription. These tools keep you in charge: they compare what AI really costs, work out whether the free tier covers you, estimate the minutes a task actually saves, check what you should never paste into a prompt, practise spotting a deepfake, and walk you through using AI honestly at work, at study and at home β with the limits said out loud. No hype, no doom, no magic words: just the maths, the habits and the human. The full detailed report costs less than a coffee: $2.95.

AI subscriptions are sold by the month and forgotten by the year. This calculator takes the three tools you pay for (or are considering), asks what each costs and β the question nobody asks β how many hours a week you genuinely use it, then returns the monthly total, the yearly total and the honest cost per hour of real use. That last number is the one that reframes everything: a $20-a-month tool you touch for two hours a week is more than $2 an hour, and a free tier doing the same job starts looking very different. Compare first, subscribe second, and review the list twice a year.
Compare up to three AI tools side by side β what each costs a month, how many hours a week you genuinely use it, and the honest cost per hour of real use that the marketing never shows.
A free tier you would genuinely use for the job, not one that exists in name only. If the free version runs out of messages after a morning, price it as a paid tool and let the calculator show what the upgrade really costs per hour of use.
The monthly total is divided by your weekly hours of real use multiplied by 4.33 weeks. It is a planning figure, not an accounting one β the point is the comparison between tools, and the honesty of seeing a $240-a-year subscription against two hours of weekly use.
Every six months is a sensible rhythm. AI pricing, free tiers and your own usage all shift faster than any subscription review you have ever done, and the tools you stopped using are exactly the ones that keep billing.
Every tool answers instantly from our own knowledge and calculators β no AI wait, no account. Honest maths and plain-language guidance, always educational and never a substitute for professional advice: AI tools change fast and vary by provider, so each answer tells you what is generally true, what to verify yourself, and what your next step should be β never hype, never doom, never a promise that a bot will fix everything. AI output can be wrong, biased or invented, so the habits here (verify, protect your data, keep a human in the loop) matter more than any model. Results are estimates and next-step aids, not professional opinions, and nothing you type is stored. Want the deeper, personalised version? Each has a $2.95 full report.
