+
+## What This Is
+
+A personal web app for capturing tasks and thoughts with image attachments, accessible from any device. Replaces scattered paper notes and Samsung Notes by providing a single place to capture, organize, and find things — especially from laptop where Samsung Notes doesn't work.
+
+## Core Value
+
+Capture and find anything from any device — especially laptop. If cross-device capture with images doesn't work, nothing else matters.
+
+## Requirements
+
+### Validated
+
+(None yet — ship to validate)
+
+### Active
+
+- [ ] Capture tasks and thoughts from any device via web browser
+- [ ] Distinguish between tasks (actionable) and thoughts (reference)
+- [ ] Attach images to entries (from file upload or camera)
+- [ ] Organize entries with tags (emergent, not predefined categories)
+- [ ] Find entries by tag, time, or search
+- [ ] Add notes to existing entries
+- [ ] Digitize paper notes by photographing and tagging them
+
+### Out of Scope
+
+- Mobile native app — web-first, browser works on all devices
+- Real-time collaboration — personal tool, single user
+- Offline mode — online-first for v1
+- OCR/text extraction from images — manual tagging is fine for now
+- Calendar integration — focus on capture and retrieval first
+
+## Context
+
+**Current pain:**
+- Paper notes scattered, hard to find
+- Samsung Notes works on phone/tablet but no web access for laptop
+- Finding things means manually scanning through piles
+
+**User profile:**
+- Senior software engineer, DIY mindset
+- Comfortable with self-hosting and container deployments
+
+**Learning goals:**
+- Vibe coding (AI-assisted development)
+- Container deployments
+
+This project solves a real problem while serving as a vehicle for learning new approaches.
+
+## Constraints
+
+- **Deployment**: Container-based — user wants to learn/practice container deployments
+- **Platform**: Web app — must work in any modern browser
+- **User**: Single user (personal tool) — no multi-tenancy needed for v1
+
+## Key Decisions
+
+| Decision | Rationale | Outcome |
+|----------|-----------|---------|
+| Web app over native | Works on all devices including laptop without app stores | — Pending |
+| Tags over folders | Flexible organization, items can have multiple tags | — Pending |
+| Images from day one | Core need is digitizing paper notes | — Pending |
