Every week, dozens of new AI tools launch. Most of them are wrappers around the same models, dressed up with a landing page and a monthly fee. Our job at MustUseAI is to tell the difference between the tools worth your money and the ones that are not — and we take that job seriously.
Here is our process. First, we research: we read the documentation, check the actual pricing page (not the marketing headline), and look for a real free tier or trial so you can verify our claims yourself. If a tool hides its pricing, that is already a red flag.
Second, we score what matters: does it do one thing genuinely well, is the output quality consistent, and would we pay for it ourselves? Our ratings reflect that judgment call — a 4.8 means we would happily put our own credit card down.
Finally, we revisit. AI tools change fast: prices move, features get cut, quality drifts. We re-check listings regularly and update our verdicts. If a tool stops being worth it, it leaves the directory. That is the deal.
