Kurage Architect
From conversation to implementation-ready design docs."I know what I want to build, but the requirements won't come together." Kurage Architect grows that vague idea into a system design document you can implement from directly — by talking it through with AI. Open source, powered by a local LLM (Gemma 4).

What it does
Asks 1–3 focused questions at a time, separating decisions, proposals, assumptions and open questions.
Architecture, class and sequence diagrams in Mermaid, embedded straight into the design doc.
Export as Markdown, requirements JSON, HTML or PDF — a perfect input for AI coding sessions.
The brain is a local Gemma 4. Your ideas are never sent to external AI providers.
Your design matures through 7 stages: discover → clarify → specify → plan → design → review → ready.
Even if the LLM fails, your answers are saved. Resume the design when it recovers.
HOW IT WORKS
Three steps
No registration. Design projects are isolated per X account.
A short description is enough. Kurage asks the right questions to firm up requirements.
Download as Markdown / JSON / Mermaid / PDF and go straight to implementation.
