Hi, I'm Aion Ren — the researcher, tester, and writer behind UseThisAI.fyi. I've spent the last two years immersed in the AI tools landscape: testing products, reading documentation, joining beta programs, interviewing founders, and — most importantly — talking to real professionals about what actually works in their daily workflow.
I built this site because the AI tools market is chaotic. Every week brings dozens of new launches, most of them promising to "revolutionize" something. Professional review sites often just repackage press releases. Reddit threads go out of date within months. LinkedIn influencers promote tools they've used for 10 minutes. I wanted one place where every recommendation is backed by actual hands-on testing — not hype, not affiliate commissions, not guesswork.
This is a one-person operation. No AI-generated reviews (the irony), no outsourced research, no paid placements. Every tool you see recommended here — I've used it myself. If I haven't tested it, it's not on the site. Simple as that.
Every tool that makes it onto UseThisAI.fyi goes through the same rigorous evaluation process. No exceptions, no shortcuts. Here's exactly what I do:
Step-by-step tutorials walking you through setup, configuration, and advanced usage for each AI tool. Not just "click this button" — we explain the why behind each feature.
Detailed pricing breakdowns across all plans, including hidden costs, usage limits, and whether the free tier is actually usable. We tell you when a "free" plan is really a trial.
Balanced pros and cons based on hands-on testing. We don't sugarcoat limitations, and we never accept payment for positive reviews. Affiliate relationships are always disclosed.
AI tools organized by what you actually do — not generic categories. A lawyer needs different tools than a marketer. We respect that, and our recommendations reflect it.
No pay-to-play. We never accept payment for reviews, ratings, or placement. Tool providers cannot buy their way onto this site or influence their ranking. If a tool is listed, it earned its place through testing.
Affiliate transparency. Some links on this site are affiliate links — if you sign up through them, we may earn a small commission at no extra cost to you. Every affiliate relationship is clearly marked. Affiliate status has zero influence on our ratings or recommendations.
We prioritize your profession, not our commissions. In several categories, we recommend fewer tools than our competitors — not because we're lazy, but because only a handful met our standards. We would rather list two tools we trust than twenty tools we haven't properly tested.
Updated continuously. The AI landscape changes monthly. We track updates across all recommended tools and refresh reviews when things change. The "Last Updated" date on every review tells you exactly when it was last verified. Our goal: no review older than 6 months without a re-check.
Human-tested, human-written. Every word on this site was written by a person who actually used the tool. We use AI tools extensively — but we don't use them to write our reviews. The irony of AI-generated AI tool reviews is not lost on us.
Have a tool you think I should review? Found outdated information? Want to suggest a profession I haven't covered yet? I read every message — seriously.

I typically respond within 48 hours. If you're a tool founder requesting a review, please include details about your free tier or trial access — I don't review tools I can't test properly.
