Upload templates, feed in data or prompts, AI generates polished documents (proposals, reports, invoices, contracts). Export as PDF, DOCX, or HTML.
**Core Features:**
- Template library (proposal, invoice, report, contract, letter, resume)
- Visual template editor with placeholder fields
- AI-powered content generation (fill sections from prompts or data)
- Variable substitution from JSON/CSV data sources
- PDF and DOCX export with professional formatting
- Document history and versioning
- Team collaboration (share templates, review documents)
- API for programmatic document generation (for integration into other tools)
- Bulk generation (generate 100 personalized invoices from a CSV)
- OAuth login (Google, GitHub)
**Technical Architecture:**
- Backend: FastAPI with background task queue (ARQ/Celery) for long-running AI + PDF generation
- AI: Claude API for content generation, structured output for template filling
- PDF: WeasyPrint or Puppeteer for HTML→PDF conversion
- Storage: MinIO/S3 for generated documents and uploads
- Auth: OAuth2 (Google, GitHub) + email/password
- Database: PostgreSQL (templates, documents, users)
- Frontend: Next.js with rich text editor and document preview
**Framework Development Required:**
*jestech-api additions:*
- Background task queue abstraction (ARQ or Celery with Redis broker)
- Task status tracking and progress reporting
- File storage abstraction (upload, download, presigned URLs, lifecycle policies)
- PDF generation helpers
- OAuth2 social login (Google, GitHub providers)
- Per-user/tier rate limiting
- Claude API integration helpers
*@jestech/ui additions:*
- Rich text editor component (Tiptap/ProseMirror based)
- File upload with drag-and-drop + progress indicator
- Template preview/renderer
- Accordion component
- Side-by-side diff viewer (template vs generated)
- PDF viewer embed
- Progress bar / task status tracker
- Markdown renderer
**Why Fourth:**
Builds on billing (FormForge), charts (Analytics), and real-time (CommandPost). Adds the AI integration layer, background jobs, and file storage that enable a whole class of AI-powered products. The rich text editor becomes reusable across many future projects.
**Revenue Model:** Free (5 docs/mo) → Pro $19/mo (100 docs, all templates, API access) → Business $49/mo (bulk generation, team, priority AI)
