Verdict on BST

BST is the best option if your primary cross-sell strategy is Amazon-style "frequently bought together" recommendations. The AI-powered suggestions are genuinely smart, and the mobile-first design ensures bundles look great on every device. The free plan is limited to 1 manual bundle, but the Core plan unlocks AI recommendations at a fair price. If you want focused cross-sell rather than a full bundle builder, BST delivers.

Key Features

  • Abandoned checkout recovery via WhatsApp messages
  • Customer workflows for returns, feedback, and order updates
  • WhatsApp-based remarketing and customer retention campaigns
  • Interactive quiz and spin-the-wheel engagement tools
  • AI chatbot trained on FAQs and store documents

Verdict on Irin

Irin AI is a WhatsApp marketing tool with AI chatbot capabilities. With zero reviews and starting at $29/month, it is completely unproven and expensive. The concept of WhatsApp-based customer engagement is sound but better-established alternatives like Interakt exist.

Does it work on mobile?

Yes, BST is built mobile-first. The widget automatically adapts to screen size and is designed to look great on phones, tablets, and desktops.

Can the AI chatbot be trained on my store data?

Yes, you can train the chatbot on your FAQs and store documents. The Pro plan supports unlimited documents and URLs for training.
