- Hey HN, I built Underpriced AI to solve a problem I had as a part-time reseller: standing in a thrift store trying to figure out if something is worth buying. How it works: - Snap a photo of any item - AI identifies the brand, model, maker, era, etc. - Pulls recent sold prices from eBay and other marketplaces - Gives you an instant valuation with confidence
- Post excerpt:
- I built this to help resellers (people who buy items at thrift stores/estate sales and flip them on eBay) figure out what things are worth before buying. You take a photo, the app identifies the item and pulls comparable sales data to estimate value. It also generates listing titles and descriptions.

- Post excerpt:
- I built Underpriced AI, an app that identifies items from photos using Claude Vision and prices them using real sold data from 6 marketplaces (eBay, Poshmark, Mercari, etc.). This week I added barcode scanning as an alternative input. The interesting part is the cost savings: Photo scan: Claude Sonnet 4.6 Vision (~$0.05) + Perplexity Sonar (~$0.004) = ~$0.05

# Design Brief: Gradient Glow
Luminous radial glows and translucent glass panels, widely used across modern AI products.
## Design Tokens
```css
:root {
--background: #050a08;
--surface: #161c19;
--foreground: #f4f6f5;
--muted-foreground: #9aa39c;
--accent: #3dcf8a;
--radius: 16px;
--font-heading: "Inter", ui-sans-serif, system-ui, sans-serif;
--font-body: "Inter", ui-sans-serif, system-ui, sans-serif;
}
```
Color area ratio: Background #050A08 (~55%) · Surface #161C19 (~15%) · Text #F4F6F5 (~12%) · Muted Text #9AA39C (~8%) · Accent #3DCF8A (~10%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.
## Layout & Conversion Structure
- Hero layout: Split Copy & Visual
- Navigation: Full-Width Top Bar
- Theme & density: Dark · Balanced
- Border radius & elevation: Large Radius; use elevation shadows to separate layers
- Primary visual medium: Product UI Screenshot / Component
- Conversion CTA: Start Free / Sign Up · Trust bar uses User Count, Rating, or Key Metrics
- Headline hook: Direct Action Command
- Hero components: Large Hero Product Shot, Metrics Strip
- Spatial layout notes: Split Copy & Visual hero structure paired with start free / sign up CTA and user count, rating, or key metrics.
- Visual summary: Gradient Glow (Dark canvas, balanced density) featuring split copy & visual layout and product ui screenshot / component visuals.
## Avoid
- Muddy low-contrast text over gradients
- Overuse of full-screen rainbow backgrounds
- Cluttered dense tables in the hero
Implement the UI following the design tokens and layout specifications above: use only these color variables, and reserve the accent color strictly for primary actions and active states. Adopt only this visual style—never copy any reference product’s brand name, logo, copy, or imagery.
