Status: Evolved into ShopForge · Core ideas proven here; agentic architecture built there

A full-stack web application for Etsy sellers managing digital products. ShopSmith was the proving ground. It validated that AI-powered content generation, structured publish workflows, and local-first data ownership could meaningfully reduce the friction of running a digital art print shop. The lessons learned here directly shaped ShopForge’s architecture.

Key Features

AI-Powered Content Generation: Uses Google Gemini to analyze product files and auto-generate titles, descriptions, tags, mockup images, and risk flags optimized for Etsy’s marketplace.

Guided Publish Workflow: A 9-step keyboard-driven workflow that walks sellers through the entire listing process, from template selection through evidence recording, with copy-paste automation and readiness validation.

Upload Kits: Downloadable ZIP bundles containing properly named images, digital files, text content, and step-by-step instructions for offline publishing.

CSV Reconciliation: Bulk-match published Etsy listings using CSV exports with 3-tier matching (SKU, title + price, title-only) for tracking what’s been published where.

Architecture

Built with React 18 and Express on a fully TypeScript stack, backed by SQLite for local-first data ownership. Includes Sharp for image processing, FFmpeg for media handling, and Real-ESRGAN for image upscaling. The application uses content-addressed blob storage with SHA hashing for version tracking and derivative caching.

The publish system uses an abstracted provider model (EtsyManualProvider) designed for future API integration without changing the core workflow. Sixteen readiness checks with severity tiers (blockers vs. recommendations) ensure listing quality before publish.

What Carried Forward

ShopSmith’s procedural pipeline worked, but it didn’t learn. Every listing started from scratch: no memory of what prompts produced better images, no awareness of which copy patterns drove more sales, no ability to adapt its own behavior. That ceiling is exactly what motivated the shift to an agentic architecture in ShopForge, which added self-improving memory, multi-tier QA, and graduated autonomy on top of the domain knowledge proven here.
