Turn your idea into a build-ready scope.
Fullscope asks the questions that matter and turns a rough idea into a scope your coding agent can build from.
Enter starts. Shift+Enter adds a line.
Why Fullscope
Stop making product decisions while the agent is coding.
Every choice you never made gets made for you mid-build, by a model optimizing for plausible. Fullscope moves those decisions to before the first line of code, where they are cheap to change.
Better than a blank chat.
A chat window leaves you to guess what to say. Fullscope leads with real questions, one at a time, each shaped by what you answered before. Choices when the options are knowable, free text when they are not, and a recommendation when the evidence already points somewhere. You can always overrule it.
Watch your project take shape.
Answers do not vanish into a transcript. They become a living scope: the problem, the users, what version one includes, what it deliberately leaves out, and the decisions behind all of it. Open questions are tracked, not forgotten.
Bring the result anywhere.
Scope it in Fullscope. Build it in Claude Code, Codex, Cursor, Kiro, Lovable, Replit, or whatever you use next. The scope leaves as clean, structured files a coding agent can follow, not a wall of prompt text.
How it works
Start with the idea in your head.
One sentence is enough. Fullscope opens a Project around it and asks the first question.
Answer real questions.
Each question is chosen because of everything you have said so far, and asked in the cheapest way that gets a reliable answer.
Make the calls that matter.
Fullscope recommends where it can and asks where it cannot. Unknown is a valid answer; it gets tracked instead of papered over.
Take away a build-ready scope.
A complete, structured record of what to build, what to skip, and why. Ready for the coding agent you already use.
