Certainly Review (2026): Features, Pricing & Verdict
Certainly is the most ecommerce-native conversational AI platform in this review series. Founded in Denmark (originally as BotXO) and trusted by Carlsberg, Booking.com, Tiger of Sweden, Trustpilot and Siksilk, it was built from the ground up for online retail — not adapted from a generic chatbot tool. Its proprietary NLU engine covers 90% of common ecommerce customer queries out of the box, supplemented by LLM integration for human-like open-ended responses. Beyond support deflection, Certainly actively drives revenue: sizing assistance, product recommendations, upselling and cart guidance turn the chatbot from a cost centre into a growth lever. The trade-off is enterprise positioning: no public pricing, custom contracts from approximately $650–$1,200/month, and a platform recommendation of $1M+ annual revenue before deployment makes sense. This is not a tool for small stores or those testing chatbots for the first time.

What Is Certainly?
Certainly (formerly BotXO) is a conversational AI platform built exclusively for ecommerce. Where general-purpose chatbot builders cover a wide surface area of business types, Certainly has spent years focusing on one question: how do you make AI conversations increase revenue and reduce support cost for online retailers? The result is a platform with pre-built intents for 90% of the most common ecommerce queries — sizing, product questions, order tracking, returns, promotions — combined with proprietary NLU (Natural Language Understanding) trained on millions of ecommerce conversations, supplemented by LLM integration for natural, contextual responses when query complexity demands it.
The platform is headquartered in Copenhagen with customers and partners in over 20 countries. Its customer list spans fashion (Siksilk, Tiger of Sweden, Rat & Boa), food and beverage (Carlsberg, Feastables), travel (Booking.com), professional services (Trustpilot, Deloitte) and logistics (Pakke.dk). The breadth of ecommerce verticals represented in that list is itself a signal of the platform’s general applicability within online retail.
Core Features
Ecommerce-specific NLU + LLM hybrid
Certainly’s core AI architecture combines two layers. The first is its proprietary NLU engine — trained specifically on ecommerce conversations and pre-loaded with intents for the queries online retailers see most. This delivers high accuracy on structured questions like “what’s my order status,” “do you have this in a size 10,” or “what’s your return policy” without requiring extensive custom training. The second layer is LLM integration (OpenAI ChatGPT) that handles open-ended, contextual queries that fall outside structured intents — keeping conversations natural even for edge cases the NLU hasn’t seen. This hybrid approach avoids the brittleness of pure rule-based systems without sacrificing the accuracy that ecommerce queries require.
Zero-party data collection
One of Certainly’s genuinely differentiated features is its zero-party data collection capability. As visitors interact with the chatbot, the platform captures declared preferences — style preferences, size, budget range, product interests — which are stored and can be fed back into CRM and marketing tools like Klaviyo. This transforms customer conversations from one-off support interactions into a continuous data asset. Pakke.dk reports 4× higher conversion rates for traffic coming through the chatbot versus standard web navigation, and Siksilk attributes a 40% Average Order Value increase to Certainly’s conversational product guidance.
Conversational commerce — sales, not just support
Certainly frames the chatbot explicitly as a digital twin of your best salesperson rather than a support deflection tool. Beyond answering questions, the platform can guide users through product selection, recommend complementary products (“frequently bought together”), handle size selection on the product detail page, add products to cart, and walk customers through checkout. The AOV impact — a 20% lift is cited by Sharma Brands CEO Nik Sharma — is the metric Certainly leads with in its marketing, and it’s backed by documented case studies from multiple customers.
Integrations and channels
Certainly integrates with 30+ platforms including Shopify, BigCommerce, Magento, Zendesk, Freshdesk, Gorgias, Dixa, HubSpot, Klaviyo, Facebook Messenger, Instagram, Microsoft Teams, Jira, Pipedrive and Azure. Deployment covers website widgets, mobile apps, Messenger and Instagram. The 14+ language support with particular strength in Scandinavian languages (Danish, Norwegian, Swedish, Finnish) reflects the platform’s geographic roots and makes it particularly strong for Nordic ecommerce expansion.
Real-World Performance
Scored Categories
Pricing
| Tier | Approximate range | Typical profile |
|---|---|---|
| Standard | ~$650/month | Mid-market ecommerce, single brand |
| Advanced | ~$1,200/month | Multi-brand, multilingual deployment |
| Enterprise | Custom | Large-scale, bespoke integration, global rollout |
Certainly explicitly positions itself for ecommerce businesses with at least $1M annual revenue and 10,000+ monthly site visitors. Brands below that threshold are advised to focus on other tools until they reach a scale where conversational commerce delivers meaningful ROI. The G2 and Capterra reviews consistently rate support quality highly, suggesting the team provides meaningful onboarding value for the price point.
Strengths
- Deepest ecommerce NLU in category — 90% of common queries pre-built
- Proven revenue lift: +40% AOV (Siksilk), 4× conversion (Pakke.dk)
- Zero-party data collection — preferences captured for CRM/marketing
- Cart guidance, upselling, sizing assistance — sales not just support
- Carlsberg, Booking.com, Trustpilot customer validation
- 30+ integrations: Shopify, Klaviyo, Gorgias, Zendesk, HubSpot
- 14+ languages with Scandinavian NLU strength
- G2 consistently praises support responsiveness
Weaknesses
- No public pricing — enterprise contract required
- Minimum ~$650/month excludes small and early-stage stores
- Platform not suited for businesses below $1M revenue / 10k traffic
- Can freeze with large datasets (user-reported on G2)
- Builder simplicity limits channel-specific customisation (G2 feedback)
- Advanced features require developer involvement
- Complex multilingual rollout can take weeks to months
Verdict: 7.8 / 10 — The Ecommerce Conversational AI Standard; Premium Priced
For high-growth ecommerce brands with the traffic and revenue to justify the investment, Certainly is the most purpose-built conversational AI platform in this category. The ecommerce-specific NLU, zero-party data collection, and documented revenue impact (not just ticket deflection) make it qualitatively different from general-purpose chatbot builders adapted for online retail. The pricing — enterprise-only, $650–$1,200/month minimum, no self-service — creates a meaningful access barrier. For brands at the right scale, the ROI math from AOV lift and ticket deflection typically closes quickly. For everyone else, Botsonic, SiteGPT or Chatbase will serve the FAQ automation need at a fraction of the cost while you build toward the revenue threshold where Certainly makes sense.
Frequently Asked Questions
What makes Certainly different from general chatbot builders?
Certainly is built exclusively for ecommerce, with a proprietary NLU engine trained on millions of ecommerce conversations. It comes pre-loaded with intents for 90% of the most common customer queries in online retail — sizing, order status, returns, promotions, product questions — rather than requiring you to build these from scratch. It also includes sales features (cart guidance, product recommendations, upselling) that general-purpose chatbot builders don’t offer. The downside is that it’s not suitable for non-ecommerce use cases.
What is zero-party data and why does Certainly emphasise it?
Zero-party data is information customers explicitly share during a conversation — style preferences, size, budget range, product interests. Unlike third-party cookies (which are disappearing) or inferred behavioural data, zero-party data is declared and consented. Certainly captures this during chat interactions and can feed it into connected CRM and marketing platforms like Klaviyo to enable highly personalised follow-up communications and product recommendations. This turns chatbot conversations into a durable marketing asset.
Is Certainly suitable for small ecommerce businesses?
No — Certainly explicitly recommends its platform for stores with at least $1M annual revenue and 10,000+ monthly visitors. Brands below this threshold are unlikely to generate enough conversation volume to justify the custom enterprise pricing ($650–$1,200/month minimum). For smaller ecommerce businesses, tools like Botsonic ($16/month), SiteGPT ($19/month) or Chatbase ($40/month) deliver FAQ automation at a fraction of the cost.
What ecommerce platforms does Certainly integrate with?
Certainly integrates natively with Shopify, BigCommerce and Magento on the commerce side, and with Gorgias, Zendesk, Freshdesk and Dixa on the helpdesk side. CRM and marketing integrations include HubSpot and Klaviyo. Additional integrations cover Facebook Messenger, Instagram, Jira, Microsoft Teams, Pipedrive and Microsoft Azure, with over 30 integrations total.
How long does it take to deploy Certainly?
A basic single-language deployment for a Shopify store can be operational within a few days. Multilingual deployments across multiple markets — particularly if requiring customisation across brand tone, regional policies and multiple language NLU models — can take weeks to a couple of months. The setup complexity scales with the breadth and depth of the deployment, not with the technical capability required (the platform is no-code for the core build).
