Frequently Asked Questions
What is the best AI chatbot tool for small businesses in 2026?
Tidio is the best starting point for most small businesses — easy to set up, strong free plan, and works on any website. For businesses wanting a chatbot trained specifically on their content, Chatbase is the best choice and takes under an hour to configure from scratch.
Can I build an AI chatbot without coding?
Yes. Chatbase, Tidio, ManyChat, HubSpot, and Landbot all require zero coding. Upload your content or connect your accounts, customize the flow, and deploy. Botpress and Voiceflow have no-code modes but benefit from technical knowledge for advanced use cases.
What's the difference between a chatbot and a live chat tool?
A chatbot handles conversations automatically using AI or pre-defined rules — no human required. Live chat requires a human to respond. Most modern tools like Tidio and Intercom combine both — AI handles routine questions and escalates to a human when needed.
How does ManyChat's comment-to-DM automation work?
You set a keyword trigger on an Instagram or Facebook post. When someone comments that keyword, ManyChat automatically sends them a DM with your message, link, or offer. It captures their contact info, adds them to a sequence, and follows up automatically — all triggered by a single comment on your post.
Is Chatbase good for customer support?
Yes — especially for knowledge-base style support. Train it on your FAQs, documentation, and product info, and it answers customer questions accurately 24/7. For complex support with ticket management, routing, and escalation workflows, Intercom or Tidio handle those better.
