Costs vary widely: AIFlowChat starts at $0 (freemium), $29/month (basic), up to $150+/month (enterprise). Chatbase starts at $0, $50/month for small business. Tidio is $25/month. Relevance AI is enterprise-only, starting at ~$5k/month. Botpress open-source is free forever (plus infrastructure costs).

Can I train a chatbot on my company documents?

AIFlowChat, Chatbase, and Botpress all support document training. Chatbase is fastest for this use case (8-15 minutes for 100+ page PDFs).

Is an open-source chatbot builder suitable for production?

If you have a DevOps team. Botpress is production-ready and deployed by 50,000+ developers. The tradeoff: you manage updates, security patches, and infrastructure. For teams without DevOps, a managed platform like AIFlowChat is safer.

How accurate are AI chatbots trained on documents?

Document-trained chatbots are 88-93% accurate for FAQ-style questions. Chatbase achieved 91% accuracy in our testing. Accuracy drops for out-of-domain questions (where the document doesn't contain an answer). Always pair with human fallback options.

AIFlowChat, Chatbase, and Relevance AI all offer white-label options, allowing you to customize the domain, branding, and appearance. This typically requires a paid plan—AIFlowChat starts at $50+/month, Chatbase at $50+/month, and Relevance AI has custom enterprise pricing. White-label is ideal for agencies and resellers.
