Spec inputs
Markdown output
Ready to generate.
Review the generated draft
Generated structure is useful, but the review still matters. Confirm that every MUST has a matching acceptance criterion, every non-goal is concrete, and every verification line is something a reviewer can actually observe.
After generating the draft, paste it into the Ambiguity Checker and compare it with the Spec Review Checklist.
What does the Spec Builder generate?
It generates a markdown technical specification with context, requirements, non-goals, edge cases, acceptance criteria, verification, rollout notes, and open questions.
Does the Spec Builder send my idea anywhere?
No. The tool runs client-side in the browser and does not submit form contents to a backend.
Is the generated spec final?
No. Treat it as a structured draft. A human still needs to confirm product decisions, architecture constraints, examples, and verification coverage.
Can I download the generated spec?
Yes. The generated markdown can be copied or downloaded as a .md file from the browser.
