Why did we build this? We noticed many users only need advanced AI models like o3 and o3 Pro occasionally, but existing solutions require a $200/month subscription. That’s expensive for people with urgent, one‑off problems. What’s unique about our launch? You can access top-tier models (o3, o3 Pro, o1 Pro, GPT‑4.1, etc.) instantly, pay only when you need them, and even try them out for free - no heavy commitment or recurring cost. What we’re most proud of? We built the entire system ourselves app, landing page, backend and already onboarded 50 early users. We’re proud to give people affordable access to cutting‑edge AI exactly when they need it most.
