Frequently asked questions
Can a small business set up an AI chatbot without coding?
Yes. Many tools on this list, such as Chatbase, BotPenguin and Askli, use no-code builders. You usually upload your FAQs, website pages or documents, adjust the bot's tone and then add it to your site with a short code snippet.
Will an AI chatbot give customers wrong answers?
It can, especially if its training content is incomplete. Keep your help content up to date, test many real questions before launch, review conversations regularly and make it easy for customers to reach a human.
Can AI chatbots work on WhatsApp?
Some can. BotPenguin lists WhatsApp support, and several other platforms deploy to messaging apps. Check each tool's supported channels and any setup requirements for WhatsApp Business before choosing.
Are there free AI chatbot tools?
