Your app idea → a tiny v1 plan + your first 3 prompts

FirstThree turns a one-sentence app idea into a tiny v1 plan for the AI builder you use (Cursor, Lovable, Bolt, Replit or ChatGPT). You get what v1 includes, what to skip and why, the simplest stack, the main screens and three copy-paste prompts in build order. Free, no sign-up, ideas aren't stored.

Hi, I'm Yuri. I'm an IT manager, and I build small things with AI tools in my spare time. The thing that kept killing my projects was the first prompt. I'd ask for the whole app, get a pile of half-working features, and give up.
FirstThree is the step I now do before opening the builder. You describe the idea in one sentence and pick Cursor, Lovable, Bolt, Replit or ChatGPT. It gives you a tiny v1, a list of what to skip, and three prompts in order, each ending with a "Done when" check. It's free, you don't need an account, and ideas aren't stored.
It won't always get the scope right, and that's the feedback I'd find most useful: where did it cut too much or too little for your idea?
