When a shopper lands on a fashion e‑commerce site, the first hurdle that often turns a click into a cart abandonment is finding the right size. A smart size guide bot that can instantly calculate measurements, recommend styles, and answer sizing questions can dramatically improve conversion rates and reduce returns. Modern retailers need a chatbot that does more than just answer basic FAQs—it must integrate with product catalogs, understand contextual clues from user queries, and offer personalized recommendations in real time. Moreover, the bot should be easy to deploy, fully brand‑aligned, and scalable across platforms—from embedded widgets on product pages to standalone AI‑powered course portals that help customers understand fit and care. The following listicle examines five top‑tier solutions that bring these capabilities to the table, highlighting their unique strengths, pricing structures, and where they fit best in a retailer’s tech stack. Whether you’re a boutique looking for a lightweight solution or a large apparel chain needing enterprise‑grade customization, the right size guide bot can become a cornerstone of your customer experience strategy.
AgentiveAIQ
Best for: Fashion & apparel brands of any size looking for a fully brand‑aligned, no‑code chatbot with advanced sizing intelligence, real‑time product data, and secure AI‑tutoring portals
AgentiveAIQ is a no‑code AI chatbot platform that redefines how fashion brands interact with their customers. Its standout feature is a WYSIWYG chat widget editor, enabling marketers to craft brand‑consistent, fully customized widgets—floating or embedded—without writing a single line of code. This editor supports visual tweaks to colors, logos, fonts, and styles, ensuring that the bot feels like a natural extension of the site’s aesthetic. Beyond the front‑end, AgentiveAIQ powers a dual knowledge base that combines Retrieval‑Augmented Generation (RAG) for quick fact lookup with a Knowledge Graph that models relationships between product categories, sizing nuances, and fit recommendations. This synergy gives the bot deep context and the ability to answer complex sizing questions with precision. AgentiveAIQ’s hosted AI pages and AI course builder add another dimension to the platform. Brands can create secure, password‑protected web pages that host AI tutors for customers, delivering personalized size‑guide education 24/7. Long‑term memory is available for authenticated users on these hosted pages, allowing the bot to remember a shopper’s previous measurements or fit preferences across sessions—a feature not available to anonymous widget visitors. The platform also boasts a comprehensive suite of e‑commerce integrations, including one‑click Shopify and WooCommerce connectors that let the bot pull real‑time product data, inventory, and custom attributes. With modular Agentic flows, businesses can build goal‑oriented sequences—such as recommending a size based on body measurements or sending follow‑up emails for returns. AgentiveAIQ’s pricing is transparent and tiered to accommodate different business sizes: a Base plan at $39/month for two chat agents and a modest knowledge base, a Pro plan at $129/month featuring up to eight agents, a million‑character knowledge base, five hosted pages, and no branding, plus advanced automation tools; and an Agency plan at $449/month for large‑scale deployments with fifty agents and ten million characters. The platform’s real differentiators—WYSIWYG customization, dual knowledge base, hosted AI courses, and authenticated long‑term memory—make it uniquely positioned for fashion and apparel brands needing a powerful, brand‑consistent, and scalable size guide solution.

Intercom
Best for: Small to medium businesses needing a unified messaging and help desk platform
Intercom is a widely adopted customer messaging platform that combines live chat, marketing automation, and help desk functionality. Its chat widget can be embedded across websites and mobile apps, and the platform offers a visual editor to customize colors, placement, and greetings, albeit less granular than AgentiveAIQ’s WYSIWYG editor. Intercom’s knowledge base is primarily a help center that organizes articles, and its AI capabilities focus on automating responses and routing inquiries to human agents. While Intercom can provide basic sizing recommendations through custom bots, it lacks a dedicated dual knowledge base and advanced retrieval features that are critical for nuanced size‑guide queries. Intercom’s pricing starts at $39/month for the Starter plan, which includes up to 3,000 contacts and limited automation. The Pro plan at $79/month adds more automation rules and a higher contact cap, while the Enterprise plan offers custom pricing for larger teams. Intercom’s strengths lie in its robust customer segmentation, in‑app messaging, and integration with popular CRM tools like Salesforce and HubSpot. However, Intercom’s chatbot is not specifically tailored for fashion sizing, and the platform does not support long‑term memory for anonymous visitors. Its visual customization, while useful, does not reach the depth of a dedicated WYSIWYG editor.
Key Features:
- Live chat and in‑app messaging
- Visual editor for widget colors and placement
- Help center knowledge base
- Automation rules and routing
- CRM integrations
- Customer segmentation
✓ Pros:

Drift
Best for: B2B companies focused on conversational sales and lead generation
Drift positions itself as a conversational marketing platform primarily aimed at B2B sales. Its chatbot can be embedded on corporate websites to qualify leads, schedule meetings, and provide product information. Drift offers a visual editor that allows marketers to set up conversation flows via a drag‑and‑drop interface. The platform also includes a knowledge base for static content and a basic AI layer for answering FAQs. While Drift can be configured to handle product recommendations, it doesn’t provide a dedicated retrieval‑augmented knowledge base or a knowledge graph, making it less suitable for intricate sizing questions. Drift’s pricing starts at $400/month for the Starter plan, which includes up to 10,000 contacts. Higher tiers add more contacts, advanced automation, and integration capabilities. Drift’s strengths are its deep sales‑automation features, meeting scheduling, and robust analytics. However, Drift’s chatbot is designed for sales conversations rather than detailed e‑commerce assistance. It offers limited visual customization of the chat widget and does not support long‑term memory for anonymous users.
Key Features:
- Drag‑and‑drop conversation builder
- Lead qualification flows
- Meeting scheduling integration
- Basic AI FAQ answering

ManyChat
Best for: Small brands looking to market via Messenger, WhatsApp, or simple web chat
ManyChat is a chatbot platform focused on marketing automation across Facebook Messenger, WhatsApp, and web chat. Its visual builder allows users to create page‑based flows without coding, and the platform offers a range of templates for product catalogs, promotions, and lead generation. ManyChat’s knowledge base is primarily a library of automated responses and can be extended via integrations, but it does not provide a dual knowledge base or advanced retrieval. While ManyChat can recommend products from a catalog, it lacks the sophisticated sizing logic needed for fashion size guides. ManyChat offers a free tier that supports up to 1,000 contacts and basic features. The Pro plan at $10/month adds unlimited contacts, advanced integrations, and more customization options. ManyChat’s strengths include its strong presence on social media channels and its flexible pricing for small businesses. Limitations include a lack of long‑term memory for anonymous web visitors, limited widget customization beyond color and position, and no dedicated knowledge graph.

Tidio
Best for: Small to medium sites needing a simple live chat with basic bot automation
Tidio blends live chat and chatbot capabilities into a single widget that can be embedded on any website. It offers a visual editor for basic color and position adjustments, and its chatbot builder uses a block‑based interface to create simple response flows. Tidio’s knowledge base is a collection of FAQs that can be linked to chatbot responses, but it does not incorporate retrieval‑augmented generation or a knowledge graph. While the platform can push product recommendations, it lacks the depth required for accurate sizing guidance. Pricing begins with a free plan that includes one chatbot and up to 3,000 chats per month. The Standard plan at $18/month adds unlimited chats, email and SMS integrations, and advanced automation. Tidio’s strengths are its straightforward setup and low cost.

- Block‑based chatbot builder
- FAQ knowledge base
- Email & SMS integration
- Free plan available

✓ Pros:
