Place the block once. Peakhour manages your storefront forever.

A Shopify Theme App Extension block that merchants place once via the theme editor. Peakhour controls what products appear, in what order, with what AI-generated title — autonomously, in real time, without the merchant ever touching the theme again.

10 rail types

Every rail type is intelligence-driven, not manually curated

Choose the right rail for the moment — or set to Auto and let Peakhour decide what your storefront needs right now.

Dead Stock Clearance

Surfaces your highest-risk products first. AI chooses from the current dead-stock scoring data.

Trending Now

Products with accelerating sales velocity this week — not last month's bestsellers.

New Arrivals

Products added in the last 14 days, prioritised by early engagement signals.

Price Drops

Products with active discounts or recent price reductions — auto-populated from Shopify.

Bestsellers

Top performers by revenue over the last 30 days, updated nightly.

Back in Stock

Products that were out of stock and have been restocked — high-intent signal for returning shoppers.

Low Inventory Selling Fast

Urgency rail: products with fewer than 10 units remaining and positive velocity.

Complete the Look

Category-based cross-sell: products that complete an outfit, kit, or set.

Frequently Bought Together

Order-graph recommendations: products other shoppers bought in the same session.

Auto (AI decides)

Peakhour picks the best rail type for the current moment — balancing clearance pressure, trending velocity, and inventory health.

How it works

Set it once. Peakhour manages it forever.

The merchant makes one decision — where to put the block. From there, every product selection, ordering, and merchandising decision is made by Peakhour.

01

Install the Smart Rail block in Shopify's theme editor

Open your Shopify theme editor, find the Smart Rail block in the app extensions list, and drag it to any section of your homepage, collection page, or product page. No code, no developer.

02

Choose a rail type or set to Auto — Peakhour handles the rest

Select from 10 rail types or leave it on Auto. When set to Auto, Peakhour evaluates your current inventory health, trending velocity, and clearance pressure to decide what the rail should show in real time.

03

Dead-stock intelligence feeds which products appear

The products in your rail aren't guesses — they come from your daily dead-stock scoring data. Products with the highest clearance need and the lowest recent visibility get surfaced first.

04

Every click and add-to-cart feeds back into scoring

Shopper interactions on the rail are captured as events. A product that's in the rail but getting zero clicks has a different problem than one getting clicks but no purchases. Both signals update the scoring model.

Full feature set

The storefront that manages itself

Eight capabilities that turn your product rail from a static block you maintain manually into a live, intelligent, self-managing storefront layer.

10 intelligent rail types

From Dead Stock Clearance to Frequently Bought Together — each rail type is driven by live intelligence data, not a static product collection.

Zero-code merchant setup

Place the Smart Rail block in Shopify's theme editor via drag and drop. One block, one decision. Peakhour manages everything inside it from that point forward.

AI chooses products from scoring data

The products that appear on your rail aren't manually selected — they're chosen from your live intelligence data. Dead-stock scores, velocity, and inventory levels all feed the selection.

Event tracking

Every impression, click, and add-to-cart is captured. This data feeds back into dead-stock scoring and recommendation accuracy — the storefront becomes a live data collection layer.

Discount badge & urgency labels

AI adds context labels where appropriate: 'Only 3 left', 'Price dropped', '40% off this weekend'. Generated from your actual inventory and discount data — not scripted.

On-store chat widget

Catalog-grounded chat for storefront visitors. Anonymous shoppers get instant answers; a seamless sign-in nudge converts them into known customers before the session ends.

WhatsApp handoff button

'Continue on WhatsApp' bridges the anonymous web session into your owned WhatsApp channel. One tap — the conversation context carries over, the shopper becomes known.

Works with Dawn, Craft, Sense, and more

Built as a native Shopify Theme App Extension. Compatible with all major Shopify themes — no custom theme required, no developer needed for installation.

Why it matters

"Set it once. Peakhour manages it forever."

Manual product curation is invisible work. Every weekend someone has to log in, drag products around, update featured collections, remove out-of-stock items, and add new arrivals. It takes hours and it's never perfectly current.

Smart Rail eliminates that entirely. The block you place once becomes a live intelligence surface — pulling from your dead-stock scores, your trending velocity, your inventory levels. What shoppers see tonight is different from what they saw this morning, without you touching a thing.

Without Smart Rail

  • Manually update featured products weekly
  • Out-of-stock items showing to shoppers
  • Dead stock buried in unpromoted collections
  • No data on which rail products convert

With Smart Rail

  • Rail updates itself from live intelligence data
  • Dead stock surfaced with urgency labels automatically
  • Every click + add-to-cart feeds back into scoring
  • WhatsApp handoff converts anonymous web sessions
