About
Dorian Keil handles everything on this site that can be put on a stopwatch or a spreadsheet. "Fast" and "laggy" are opinions until somebody runs the same hundred prompts through an app at 2 PM and again at 11 PM and writes down the median. That is his job. He reports p50 and p95 response times, image generation success rates, and the point at which a free tier stops answering.
He came out of software QA, and it shows in the way he reads a pricing page. Every review he touches gets a section on what you are actually charged: the currency the subscription is billed in, the foreign transaction fee that follows it, whether a "credits" model stacks on top of the monthly fee, and the exact merchant descriptor that lands on a bank statement. For an adult product, that last one is not a footnote.
The other half of his beat is the boring documents. He reads the terms of service and the privacy policy to the end, notes who the stated data processor is, whether messages are used for training, and whether a delete request removes conversations or just the login. When a service will not say, the review says that it will not say.
