Just built WeBuyBack — a resale marketplace where you can sell and buy stuff locally or online, kind of like OfferUp + AI magic.

Trying to get first 50 users. Would love feedback, early signups, or just a roast

Link: https://webuyback-marketplace-hub.lovable.app

If you flip gear, collect cool stuff, or just wanna list something, it’s free & instant.

Your site says "10k+ active users"

You're in high school? This is pretty good considering. Couple of things :

1. I uploaded a picture that was clearly an iPad Mini - it said so in the image I believe - and the AI decided it was a Pro and could not be convinced otherwise

2. eBay does the same thing, having the AI write flowery prose for the description. It's more annoying than helpful. Would be nice if, instead of the AI filling out the character limit with generic details, it could recognize it was light on info and prompt the user for specific details.

Cheers though good luck with it
