⚡ SnapToSell

On-Device AI Reseller Copilot & Real-Time Net Profit Engine
Turn thrift and estate sale finds into high-converting, platform-compliant listings across eBay, Etsy, Poshmark, Mercari, and Facebook Marketplace — powered 100% locally by open-weight AI.

Over 25 million vintage dealers, thrifters, and secondhand resellers face the same tedious bottlenecks:

1. Listing Fatigue: Writing differentiated descriptions, adhering to eBay's strict 80-character title limit, and researching 13 unique Etsy SEO tags takes 10–15 minutes per item.
2. Platform Commission Blindness: Calculating actual take-home profit after factoring in eBay final value fees (13.25% + $0.30), Etsy transaction & payment fees, or Poshmark's 20% cut is confusing and error-prone.
3. Thrift Dead Zones: The best sourcing happens in church basements, estate auctions, and flea markets with zero cellular connectivity.
4. Cloud API Bills: Paying per-image and per-token cloud API fees eats directly into a reseller's razor-thin side hustle margins.

SnapToSell is a local-first web application engineered from the ground up to solve reseller listing bottlenecks without a single byte leaving the user's laptop.
