 # Decisions Log
 
-## 2026-02-14 — Phase 0: Business Model Analysis
+## 2026-02-14 — Product: PDF API (approved by user)
+Chose HTML/Markdown to PDF API over webhook relay and JSON schema validation. Fastest to ship, proven demand, clear monetization.
 
-### Constraints Assessed
-- €200 budget, no human identity for accounts/payments
-- Must be fully automatable by AI agent
-- Digital products only
-- Human partner handles: domain purchases, account creation, payment setup
-- Available tech: Go, TypeScript, Python; Forgejo for git; can deploy on existing infra
+## 2026-02-14 — Name: DocFast
+Product name "DocFast" — short, memorable, describes value prop (fast document generation). Domain TBD.
 
-### Models Evaluated & Rejected
-- **Content/SEO sites**: Too slow to monetize, saturated, requires ongoing content
-- **Freelance marketplace**: Requires human identity, client calls
-- **Course/info product**: Need audience first, slow ramp
-- **Chrome extension**: App store accounts need identity, review process unpredictable
-- **Newsletter**: Audience building too slow for €200 budget
-- **Marketplace/platform**: Chicken-and-egg problem, needs critical mass
+## 2026-02-14 — Tech Stack: TypeScript + Express + Puppeteer
+- TypeScript for type safety and fast iteration
+- Express for simplicity (no framework overhead)
+- Puppeteer for high-fidelity PDF rendering (Chrome-based = pixel-perfect)
+- Marked for markdown parsing
+- Chose Puppeteer over wkhtmltopdf/pdfkit for better CSS support and template rendering quality
 
-### Models Shortlisted (3 proposals)
-See proposals below — sent to user for approval.
+## 2026-02-14 — Templates: Invoice + Receipt first
+Built-in invoice and receipt templates as differentiator. Most PDF API competitors are raw converters — templates add immediate value for common use cases.
+
+## 2026-02-14 — Pricing model (planned)
+- Free tier: 100 PDFs/month
+- Pro: $9/mo for 5,000 PDFs
+- Business: $29/mo for 25,000 PDFs
+- Enterprise: custom
+Not yet implemented — need Stripe integration.
