Articos is a fast, recruitment free user research platform that helps you validate product ideas, test UX flows, and understand customer needs without waiting weeks to find real participants. Instead of booking calls and chasing no shows, you run AI moderated interviews with realistic synthetic users that match your target personas. In a short time, you get clear feedback on what people understand, what confuses them, what they would pay for, and what would stop them from using your product. It is built for founders, product managers, designers, and agencies who need quick direction before they commit time and budget to building the wrong thing.
