Clerk.io review: AI search, recommendations, chat, audience and email for online stores. Usage-based pricing, free trial, Shopify and Magento support.
Researched and fact-checked by Bartu Cavusoglu · Updated October 26, 2026
Clerk.io is an AI platform for online stores. Its pitch is that stores already pay to bring shoppers in, so every visitor who leaves without buying is lost money. The platform tries to help shoppers find the right products, add more to their baskets and come back later.
It is made of five products: Search, Recommendations, Chat, Audience and Email. The founder, Hans-Kristian Bjerregaard, previously worked at the Danish retailer Unisport and built Clerk.io around one system that connects people and products, rather than separate tools that need constant manual tuning.
A store connects to Clerk.io once, through a direct platform integration or the open API. Customer and product data is then brought into one shared platform, and every Clerk product works from that same data. The company says this gives all tools a complete view of each shopper instead of siloed data.
The AI uses that data to predict what shoppers browse, buy and want next. Personalization relies on sales and behavioral data rather than cookies, and each product adapts in real time. The same engine drives search results, recommendations, chat answers and email content.
Search covers intent, typos, behavior, sales data and availability. Recommendations show complements, alternatives and next products, and Chat gives product-aware answers that guide shoppers toward relevant items. Together these cover discovery and basket building during a visit.
Audience turns behavior and purchase intent into segments usable in Email, Meta and Google. Email sends personalized product emails with products picked automatically. The platform also includes a customer data platform, analytics, merchandising and a predictive AI revenue calculator.
Clerk.io is an AI platform for online stores. It offers Search, Recommendations, Chat, Audience and Email, all working from one shared integration, to help shoppers find products, add more to their baskets and return.
Clerk.io uses usage-based tiers that get cheaper per unit as usage increases. The pricing page has a calculator in GBP, DKK, EUR and USD, but fixed prices are not shown in the page text. B2B and Enterprise packages are quoted individually.
Yes. The site offers a free trial and a free demo that shows the platform with the store's own products. The sources do not describe the length or limits of the trial.
It lists direct integrations with Shopify, Magento 1 and 2, BigCommerce, Shopware, WooCommerce, PrestaShop, DanDomain, LightSpeed, SmartWeb and Shoporama. Custom platforms can connect through the open API.
Usage is based on API calls for Search, Recommendations and recommendation emails, the number of uploaded customers with an email for Audience, and the number of sent emails for automated email. The knowledge center has more detail.
No one-off implementation fee is charged. Instead, the agreed usage tier is invoiced from the date of signature. Additional work beyond the implementation packages is billed as a Clerk.io Workday at 99 EUR per hour.
The company says it uses sales and behavioral data, not cookies, to deliver personalized experiences. It describes this approach as GDPR and CCPA friendly.
It suits independent and mid-market ecommerce businesses that want AI-driven search, recommendations, chat, audiences and email in one platform. B2B sellers and large operations can request custom packages.
