Capital sitting on the shelf does not sell itself. Point the camera at a piece, get a listing draft, and put it where buyers already are.

From a photo to where you sell
Adding an item by hand means typing a name, writing a description and picking a category. Then doing the whole thing again for the next item.
Photograph the item
Open RareSync on your phone and shoot the item where it stands. Photos you already have work too.

Read the draft
We fill in the name, the description and the category from the photo. Change what we got wrong, and say whether this is one unique thing or a run of identical copies.

Crosslist it to where you sell
Connect Square or Shopify and push the item across. Sell it in one place and it comes down in the others.

What goes wrong when you sell a lot of unique items

- Sold in the shop. Still up online.
- It sold on Saturday. Monday it is still listed on Shopify. RareSync keeps one record behind every listing, so a sale in one place takes it down in the rest.
- Photos and write-ups never catch up.
- New stock arrives and the listings sit, because the photos are not ready or the words are not right. Photograph the item and we write it up, and we tell you if it is already in there.
- You cannot tell which one this is.
- Six brown baskets on a shelf and no way to tell which listing is which. One gets moved and you are back to guessing. Point the camera at the basket and we pull up its listing.
What comes with it
Square and Shopify are the two stores you can connect today. You do not need either one to start: build the whole catalog first and connect a store when you are ready.

Drafts written from your photos
Name, SKU, description and category, filled in from the pictures you take.

Square and Shopify
Connect one or connect both. Your store carries on working the way it does now.

Unique, or identical copies
One of a kind gets its own record and its own photos. A run of the same thing gets a count.

One catalog behind all of it
Every item is one record, with its photos and its words in the same place. That record is what your stores are listing.

Sold once, down everywhere
A unique item can only sell once. We take it down wherever else it was listed.

Everyone who works the shop
Staff get their own sign-in, and you decide what each person is allowed to change.
A catalog from photos
Each item is one record, with its photos and its copy in the same place. That record is what every store you connect is listing.

Find it with the camera
A photo finds the item the way a scan would, without printing and sticking labels. Someone who has never seen it before can still look it up.

An account
An email address, or the Google account you already use.
A phone with a camera
RareSync runs in the browser. It is how items get into the catalog.
A store, eventually
Square or Shopify, whenever you are ready to sell.
A plan to connect it
Building a catalog and looking around costs nothing. You need a plan before a store connects.

You approve every listing
What we write is a draft. Every fact we read off the photo waits on your tick, and the item sits in your catalog until you crosslist it.

It sits alongside the store you have
Your Square or Shopify setup keeps running exactly as it does now. There is nothing to migrate and nothing to switch off.
RareSync identifies your inventory from a photo, like a barcode, without printing and sticking labels. Photograph a unique item. RareSync finds it in your catalog, or writes the listing if it is not there yet. You check the draft, then crosslist it to where you sell. Which brown basket is this? Point the camera at it. The listing comes right up. New stock gets a name and a write-up from the same photo. You read it over before it goes out. If it looks like something you already have, RareSync says so.
Start with one item
Try it free. Photograph one item and see what we write. No card needed. It runs in a browser, so there is nothing to install.
