SOI — Second-hand market

SOI.market

About this app

Buy and sell second-hand in Bangkok without the fear of getting scammed.

SOI holds the buyer's money safely until the item is in their hands, so neither side has to trust a stranger. Snap a few photos and the AI assistant writes your listing in about 90 seconds. Arrange delivery — standard courier, or Lalamove when it's urgent — without leaving the chat, and follow it end to end.

• Protected payments — the seller is paid only after the buyer confirms the item arrived
• AI listing assistant — photos become a title, a suggested price and a description
• Delivery built in — standard courier, or Lalamove when it's urgent, tracked in the app
• Chat with real offers — negotiate, accept and pay in one place
• Buyer protection on every order
• PromptPay and Thai mobile banking

Listing is always free. SOI earns a commission only when your item actually sells.
