# System Design
## Components
- Chat UI (Frontend)
- Backend (API)
- Vector DB (pgvector)
## Data Flow
- Backend → Vector DB: retrieve context
One canvas, four ways to think
Each mode gives you a tailored palette and a prompt written for the job.
System Design
Services, queues, DBs, LLMs — the whole architecture.
App / UI Flow
Screens, actions, and navigation between them.
Database Schema
Tables, relations, and types as models or migrations.
Task Planning
Work items and dependencies as an ordered plan.
Start from templates
SaaS app, REST API, RAG pipeline, event-driven — drop one in and tweak.
Agent-ready prompts
Structured markdown with components, connections, and build instructions.
Save & share
Keep diagrams in the cloud and share a read-only link with anyone.
From sketch to spec in three steps
1
Sketch
Drag nodes onto the canvas and connect them. Start from a template or a blank slate.
2
Connect
Label the edges with the data flow, actions, or relationships between components.
3
Generate
Sketchstack turns the diagram into a clean, structured prompt — ready to hand to your agent.
