ChatLab vs Verloop side by side.

Verloop is strong where it is strong: voice AI agents that handle phone calls in more than 80 languages, speech recognition trained on a very large corpus, customizable voice personas and accent handling, and a WhatsApp-first approach that suits markets where messaging is the primary channel.

Around that core it is less complete. Verloop does not train from website URLs, a sitemap or markdown, which changes how you build the knowledge base entirely. There is no choice of AI model, no creativity setting, no knowledge base optimizer, no rate limits and no domain restrictions. There is no iFrame embed, no advanced website training filters, no client summaries, no Offer Cards and no minified sender bar. On integrations there is no PrestaShop, CS-Cart or Abicart. Verloop has also moved from published pricing to a contact-sales model, and WhatsApp Business API costs are billed on top by Meta.

ChatLab is Free or $15/mo at $3.13 per 100 conversations, published on the website. For voice-first support in multilingual markets Verloop is a genuine specialist. For a website chatbot that trains itself from your pages, it is the wrong shape of tool.
