InstagramCapture paths
Start from the way your team already shoots products.
SECND supports phone-first intake on mobile and the same full workspace on web and desktop—identical tools, whichever fits your team.
Capture from the shop floor
Use the iPhone app when your team photographs products as they come off the rack, then finish review and publishing in the web or desktop app.
- Take product photos on mobile
- Start listing drafts immediately
- Continue in the web or desktop workspace
Work from web or desktop
Upload photo batches, review inventory in a dense grid, and publish across marketplaces from the browser or the desktop app—the same feature set on both.
- Process large photo folders
- Review generated products in bulk
- Publish across selected marketplaces
Workflow
One path from intake to sold.
One day-to-day workflow: bring in inventory with the AI listing tool, review exceptions, and keep every marketplace channel honest with POS-aware inventory sync.
Bring inventory in
Upload photos, import existing listings, or connect the system your shop already uses.
Let SECND structure it
AI drafts titles, descriptions, categories, tags, pricing context, and marketplace fields.
Review the exceptions
Your team works from a dense queue and only fixes the items that actually need a decision.
Publish and keep synced
Listings go live across channels, and sold inventory is delisted everywhere else.
Product surface
Show the operating system, not another cross-listing promise.
The strongest proof is the product itself: inventory density, review states, channel sync, and useful AI assistance at the point of work.

1 pass
AI where it removes work
Image understanding and listing generation sit inside the workflow instead of becoming another tool.
1 source
Physical and online stock together
Square, Shopify, and marketplace inventory stay tied to one product record.
