Planex
AI-powered project blueprint generator with multi-step wizard and streaming output
Overview
Planex is an AI-powered project blueprint generator. Users describe their project vision, configure a tech stack, select modules, and generate comprehensive planning documents through a multi-step wizard. The AI generates architecture docs, user stories, database schemas, API designs, and folder structures.

AI Integration
The AI uses an expert software architect persona and generates:
PLAN.md— Project overview and roadmap- Architecture documentation
- User stories
- Database schema design
- API design
- Folder structure recommendations
Generation is streamed section-by-section, with each section receiving previous sections as context to maintain coherence across the blueprint.
