How Kaup works
Kaup replaces endless scrolling with intent. You say what you want, the bids come to you, and a trade unlocks a private thread. Here's the full loop.
Post a Want or an Offering
Two ways to start. Post a Want to declare what you're after — Kaup surfaces matching Offerings to your feed. Or post an Offering to list something you have and let bids roll in.
Snap a photo and let AI draft the title, category, and description for you.
Bids come to you
People bid on your Offering with cash, a barter (their item for yours), or a service. Every bid opens a live window — a countdown that keeps things moving instead of sitting dead in a DM.
No haggling in the open. Bids are private until you decide.
Feature the ones you like
As bids arrive, you can Feature your favorites to signal interest without committing. Bidders see momentum; you keep control right up until the window closes.
Reputation scores travel with every trader, so you know who you're dealing with.
Pick a winner, unlock the thread
When the window closes you choose the winning bid. That — and only that — unlocks a private messaging thread to arrange the swap. No spam, no cold DMs.
AI safety scoring watches every thread for pressure, scams, and off-platform pushes.
Meet, trade, confirm
Arrange the exchange, meet up, and both parties confirm the trade is complete. Completed Trades build your reputation and unlock more of the platform.
Barter is free forever. Cash trades keep a small, transparent fee.
