Nifty is an AI-powered reselling platform that combines crosslisting, cloud automation, inventory management, and sales analytics for eBay, Poshmark, Mercari, Depop, Etsy, and Whatnot sellers.
About
Nifty is an all-in-one software platform for online resellers who sell across multiple marketplaces such as eBay, Poshmark, Mercari, Depop, Etsy, and Whatnot. It addresses the most time-consuming parts of reselling: creating listings for each platform, keeping inventory in sync, remembering to delist items after a sale, performing daily engagement tasks, and calculating actual profit after fees and expenses.
The product groups three functions into a single suite. An AI crosslisting tool fills in listing fields automatically and translates item details between marketplaces. Cloud-based automation runs platform-specific bots that share, relist, follow, and send offers even when the user's device is turned off. An analytics module records every sale, extracts marketplace fees, organizes expenses such as mileage and inventory costs, and produces tax-ready profit reports. Nifty also offers Otto, an AI assistant for resellers, and a beta MCP server for connecting external AI assistants. The service is operated by Nifty AI LLC and runs in a browser on phones, tablets, and computers.

Who It's For
Nifty is built for resellers of all sizes, from part-time thrift flippers selling a handful of items per week to full-time sellers running large multi-marketplace businesses. Typical users source inventory from thrift stores or wholesale and resell on Poshmark, eBay, Mercari, Depop, Etsy, or Whatnot. It suits sellers who want to expand reach through crosslisting, recover hours spent on repetitive engagement tasks, and understand true profit after marketplace fees — including those preparing expense records for tax season.
