How it works

How does a garment go from phone photos to sold — without you?

You photograph a garment, WonderSnap reads its tags and writes the Shopify listing, and you approve it. WonderSync then cross-lists the item to eBay Germany and eBay US. When it sells anywhere, the other listings are delisted in about two seconds — so one-of-a-kind stock can never sell twice.

WonderSnap
Photograph the garment

Up to six phone shots: front, back, brand tag, care label, an optional hang-tag and one detail. Any phone camera works — files are normalized automatically, iPhone HEIC included.
WonderSnap
The AI reads the tags first

Pass one is OCR: brand, size and fabric straight off the care and brand tags. An uncertain read isn't guessed at — a second model verifies it before it lands in your draft.
WonderSnap
A complete listing drafts itself in about a minute

Title, description, colours, tags, one of ~90 garment categories mapped to Shopify's taxonomy — and a condition line that discloses flaws instead of hiding them. Buyers trust listings that mention the repair.
WonderSnap
You approve. Nothing ships without sign-off

Uncertain fields arrive flagged in the review screen. Edit anything, set the price, and one click publishes to your Shopify store — photos, category and single-unit inventory included.
WonderSync
It cross-lists itself to eBay — in German, too

WonderSync pulls the listing from Shopify, fetches each eBay category's live required aspects, and maps your English data to the German fields ebay.de demands — Marke, Größe, Farbe, Abteilung. The US price defaults to ×1.1; photos stay on Shopify's CDN.
WonderSync
Sold once — gone everywhere in ~2 seconds

Shopify sales arrive by webhook; eBay sales are caught by 60-second polling; a 10-minute reconciliation sweep re-checks everything independently. One atomic claim decides the winner, and failed delists retry with backoff until a critical alert names the exact order to cancel.

The shelf

Two tools. One shelf. Each does one job wonderfully.

Every WonderTool is its own product with its own home — this page is the shop window. Both are built for the same person: a reseller whose every item exists exactly once.

WonderSnap

Web app · AI listing generator for Shopify resellers

Questions & answers

What resellers ask before they try a tool

What is WonderTools?

WonderTools is a Latvian app studio that builds focused tools for vintage and secondhand resellers: WonderSnap turns garment photos into ready-to-publish Shopify listings, and WonderSync keeps Shopify and eBay inventory in sync so one-of-a-kind items never sell twice. The company behind it is Brīnumbode, SIA, registration number 40203261853.

How do I stop overselling when I sell on Shopify and eBay at the same time?

WonderSync watches every channel with three overlapping layers — order webhooks, 60-second polling and a 10-minute reconciliation sweep. The moment an item sells anywhere, an atomic database claim locks it so exactly one channel can win, and the other listings are delisted in about two seconds.

How long does it take to list a vintage item on Shopify with WonderSnap?

About a minute per garment. You take up to six phone photos, WonderSnap reads the brand, size and fabric off the tags and drafts the full listing — title, description, condition with flaws disclosed, category. You review it, set the price, and publish to Shopify in one click.

How much do WonderSync and WonderSnap cost?

Do I need a Shopify store to use WonderTools apps?

Yes. Both tools connect to a Shopify store once, through a custom-app token you paste in Settings. WonderSnap publishes finished listings into that store; WonderSync additionally connects your eBay account — one sign-in covers both ebay.de and ebay.com — to cross-list and sync from it.

Can I try both tools without paying much?

Yes. WonderSync's Basic plan is free forever for 25 cross-listed products and needs no card. WonderSnap's trial is $1 once, for 10 complete listings, with no subscription required. Between them you can run a small reselling operation end to end before spending more than one dollar.

Where is my data stored, and is it GDPR compliant?

All WonderTools products run in the European Union — the database is a Supabase Postgres project in Frankfurt — and are built to GDPR requirements: data minimisation, encryption in transit and at rest, deletion on request. Marketplace credentials are encrypted with AES-256-GCM. Write to hello@wondertools.app for any data request.

Who is behind WonderTools?

WonderTools is the product studio of Brīnumbode, SIA, a company registered in Latvia under number 40203261853 — the entry is public in the company register. The name means "the wonder shop" in Latvian. The same few people design, build, host and answer support for every tool.

Give the busywork to the machines.

Both tools are built for stock that exists exactly once, and both cost almost nothing to find out. The worst case is five minutes. The best case is your weekends back.
