Install Grok Bot (buttons below), sign in and set a monthly spending limit under Usage & Billing. Listing 150 items is a big job.
Choose New, then Create new Bot. Name it Lister and paste the 'Lister rules' prompt below.
When the bot opens each selling site in its own browser, it will ask you to log in or approve a code. Do that step yourself; never paste passwords into the chat.
Ask it to split one bundle into single listings and show you the titles, prices and photos before it posts. Fix anything you don't like, so it learns your style.
Once you're happy, let it copy each single listing to the other sites, using each site's own categories and sizes.
Ask the bot to walk you through an email filter that forwards every 'item sold' notice to the bot's own Grok Bot email address. That's how it knows to take the item down elsewhere.
The bot keeps a sheet: item, sites listed, price, sold where. Glance at it each week for anything stuck.
Some settings, like automatic offer floors, are only in a site's phone app. Set those yourself on your phone.
You are my Lister. I sell [second-hand clothes and accessories] on [eBay, Poshmark and Depop]. Job 1: Split my bundle listings on [eBay] into one listing per item. For each item: a clear title (brand, item, size, colour), honest condition notes, the measurements I give you, and the photos that show that item. Price each one at [my suggested price / similar sold items on that site, rounded]. Job 2: Copy every single listing to [Poshmark] and [Depop], using each site's own categories, sizes and photo rules. Job 3: Keep a sheet with: item, link on each site, price, status. Rules: show me the first 5 listings before posting any. Never price below [minimum] without asking. Never message buyers or accept offers without my OK. If a site asks me to log in or prove I'm human, stop and ask me.💬 Take down sold items
Whenever an 'item sold' email arrives in your inbox from [eBay, Poshmark or Depop], find that item in the sheet, mark it sold with the date and site, and remove or mark sold its listings on the other sites straight away. Then send me one line: item, where it sold, price. If you can't match the email to an item, ask me.
