Step 1

One-Click Product Capture

Browse to any eBay product page, click the SyncList extension icon, and hit "Capture." Our scraper extracts everything you need in under 2 seconds:

Product title, price, and condition
Full description with formatting preserved
Up to 20 high-resolution images (auto-upgraded to max)
Item specifics (brand, size, color, material)
Full category breadcrumb path for accurate mapping

Step 2

Intelligent Auto-Fill on Every Platform

SyncList doesn't just paste text into forms. It uses platform-specific DOM manipulation to interact with React-based forms exactly like a human would — triggering the right events, waiting for dynamic content to load, and selecting the correct options from dropdowns and modals.

Each marketplace has its own dedicated filler script that understands the platform's unique form structure. Facebook's category-to-size chaining, Depop's pill-based category selection, Mercari's 3-level modal traversal — SyncList handles them all.

Pill-based category selection with 200+ category paths. Multi-select type fields, universal fields (occasion, material, body fit), and smart gender detection from eBay breadcrumbs.

Mercari

3-level category modal traversal, automated shipping flow (weight, dimensions, carrier selection), and precise condition mapping. Every field filled in under 30 seconds.

Poshmark

Category mapping, size selection, brand identification, and condition setting. SyncList handles Poshmark's unique listing flow including cover shot prompts.
