About this app

Create up to 20 listings in one go and get your time back.

1 listing = 10 seconds

Postfast is the reseller's AI assistant: from photo to sale, taking in valuation, buying and the day-to-day running of your business.

Photograph an item: the AI reads and improves your photos, writes the listing and estimates the price. You check it, tweak it, post it.

The real difference starts after the photo. Postfast doesn't stop at the listing: it tracks your sales, your purchases, your stock and your real margins.

How you use Postfast

In the morning, you photograph the day's items — ten or so, say. Once all the photos are taken, you hit generate: the listings are written in the background, and you post them to the platforms whenever you get a moment, or while the rest are still generating.

You log your purchases and link them to your sales. That way you know exactly what you're making, and which purchases pay off best.

Give your listings more visibility by posting to more platforms, with better photos, in record time.

THE LISTING
• Title, description, hashtags and estimated price, straight from your photos
• Written in the language of the country you sell in
• Up to 20 listings prepared in one go, generated in the background while you carry on posting
• AI photo editing: studio background, styled setting, invisible mannequin

Better listings, better sales.

POSTING

• Post to the platforms in your market in a few taps: Vinted, eBay, Facebook Marketplace, Etsy, Vestiaire Collective, Depop, Gumtree.
• Every platform works by assisted copy and paste: the title is copied for you, then the description the moment you need it.

TRACKING

• Sales: what's live, what's sold, what's gathering dust.
• Purchases: log what you buy from photos. The AI identifies the items and splits the cost across them pro rata. Link your sales to your purchases to see what you're really making and which job lots pay off.
• Dashboard: your margin, your sales by category and the return on every purchase in one place, so you can steer your business.
• Unsold: the list of what needs relisting, plus a guided relisting tool.
• Camera roll looking like a marketplace? Turn on automatic tidying: Postfast files your photos in a dedicated album and clears out the ones for items you've sold.

SPOT A BARGAIN

• At a car boot sale or a charity shop, photograph before you get your wallet out. The app estimates the resale value item by item and opens up price searches so you can check for yourself.
