Ello Docs
How to set up Ello Virtual Try-On, what every setting does, how the numbers are counted, and how to fix anything that looks off. The complete documentation is also published as plain text for AI assistants at /llms-full.txt.
Getting started
Install, go live, and understand plans, billing, and limits.
- Install Ello and go live — From the Shopify App Store to a working try-on button on your product pages — most stores finish in under ten minutes, with no theme code to edit.
- Run your first try-on — Test the full experience on your own store the way a shopper will meet it — and know what to expect in the first 48 hours.
- Plans, trials, and billing — What each plan includes, how the 7-day trial works, what happens at your limit, and how overage billing stays opt-in — no surprise charges, by design.
- Try-on limits, explained — Three separate limits protect your costs: your plan's monthly allowance, a fair daily cap per shopper, and an optional per-shopper limit you control.
Set up the experience
Widget Design, placements, product coverage, and the outfit upsell.
- Widget Design: choose your style — One page shapes the whole experience: pick where results appear, set your brand color, and fine-tune everything else — with a live preview that shows each change before you save.
- Placements: where try-on lives — Five ways shoppers can enter the try-on — what each looks like, when to use it, and the automatic fallbacks that make sure an entry point is always visible.
- Products: choose where Try-On appears — Scope try-on to the right products, turn it off for the ones that shouldn't have it, see what the catalog scan decided at a glance, and fix a garment's design side or a bag's carry style yourself.
- Set up Complete the Look — Offer the matching piece the moment a try-on lands — layered onto the same photo, added to the cart in one tap. You curate every pairing; nothing is random.
Measure results
The Analytics ledger, how attribution works, and the Proof test.
- Reading your Analytics — A tour of the Analytics page: the headline numbers, the four tabs, what every metric means, and the one mistake to avoid when reading per-product revenue.
- How attribution works — The exact rules behind every revenue number Ello shows you — strict enough to hand to a CFO, and auditable down to the Shopify order ID.
- The Proof test (A/B holdout) — A slice of your shoppers browses without try-on. Every lift number is measured against them — causation on your own store, not a vendor claim.
The shopper experience
What your customers see, photo guidance, and how their data is handled.
- What your shoppers see — The full journey from the shopper's side — first visit, photo, render, outfits, wardrobe, and checkout — so you know exactly what you've turned on.
- Photo guidelines: what renders best — Three essentials cover almost everything — and the widget coaches shoppers through the rest. Here's exactly what's checked, what's rejected, and why.
- Shopper photos, privacy, and data — Where photos live, what Ello stores and what it deliberately doesn't, and how data is deleted — written to be shown to your own customers if they ask.
Troubleshooting
Widget not showing, changes not appearing, and render quality.
- The widget isn't showing — Nine causes cover essentially every case — run this checklist top to bottom and you'll find yours.
- My changes aren't appearing — You saved a setting and the storefront looks the same. Almost always, that's caching doing its job — here's how to see your change right now.
- Fixing render quality issues — When a try-on looks wrong, the cause is almost always one of four things — the shopper's photo, the product's photo, the print side, or the product type. Each has a fix.
