The full lifecycle
Eight challenges every modern fashion brand faces, and how Conversational AI from Certainly resolves each one.
Shoppers browse, second-guess, and bounce. The catalogue is too big to navigate alone.
An AI agent acts as a personal stylist: occasion-based picks, outfit pairings, real-time inventory aware.
+4.2x conversion on AI-assisted discovery
70% of returns are size related. Brands fit differently. Regions size differently.
Region-aware size conversion plus brand-specific fit memory. Fewer wrong sizes leave the warehouse.
Cuts size-related returns by up to 35%
Same dress, three blues, four lengths, two fits. Customers pick the wrong one.
MCP-native Shopify integration disambiguates variants in real time, in chat, in the customer's language.
Up to 35% fewer wrong-item returns
Higher price tags mean longer consideration. Most carts go cold.
Proactive nudges, finance options, and live answers on fit, fabric, and delivery before they leave.

Best customers churn quietly. Restock alerts get lost in inboxes.

Omnichannel and brick-and-mortar
Most fashion buyers move between web, app, DM, and store within a single decision. The AI agent travels with them.
Shopper asks 'Do you have this in 38 in Copenhagen?'. Agent answers in chat with real-time inventory and reserves the item for two hours.
Pick a store, choose a window, get a QR code. No forms, no second tab. Works on web, WhatsApp, and Instagram DM.
Book a fitting room, a stylist session, alterations, or bridal. The agent reads store calendars and confirms instantly.
Tried in store but did not buy? The agent follows up on the channel the shopper prefers, with the items they actually tried on.
In-store conversational AI
Brick-and-mortar is not a separate channel, it is the moment of truth. Certainly puts the agent in the fitting room and on the associate's headset, so every visit converts and every shopper feels known.
Shopper-facing
Shoppers scan, chat, and get the right size, the right colour, or a styling pairing. No queue, no abandoned room.
Scan and chat
QR codes on mirrors and tags open the agent in the shopper's language, instantly.
Other sizes, other colours, on demand
Real-time store and warehouse stock. The agent reserves and routes to the room.
Call an associate, only when it counts
Triaged handoff to a human, with full context, when the moment is high-value.
Associate co-pilot
A clienteling co-pilot on tablet or earpiece. Customer history, product knowledge, and outreach drafts, all in one prompt.

Members ask about points, perks, and drops in chat. The agent reads loyalty data and offers early-access links to qualifying customers only.
Basics, denim, socks, base layers. One message, repeat order in the right size. Lift repeat purchase rate by up to 22%.
Saved items go on sale or low stock. The agent reaches out with a personal message, not a generic blast.
