Botpress (botpress.com) has a generous free tier and a visual flow builder — you create chatbot conversations by connecting nodes, like a flowchart. No code needed. Sign up, create a new bot, and you'll be in the builder in 2 minutes. It comes with AI (GPT-powered) built in, so your bot can understand natural language out of the box.

The fastest way to make a useful chatbot: upload your FAQ page, product documentation, or website URL to Botpress's Knowledge Base feature. The AI reads your content and automatically answers questions based on it. This is RAG (Retrieval-Augmented Generation) — it means your bot gives answers from YOUR content, not generic AI responses. Upload and your bot instantly knows your business.

Map out the 5-10 most common questions or tasks your bot needs to handle. In Botpress's visual builder, create a flow for each: greeting, understand intent, provide answer or collect info, hand off to human if needed. The AI handles natural language, so you don't need to program every possible phrase — just define the main paths.

Botpress gives you a script tag to paste into your website's HTML — one line, copy-paste, done. It works with any website: WordPress, Shopify, Wix, Squarespace, custom HTML. The chat widget appears in the bottom-right corner. Customize the colors and welcome message to match your brand. If you use WordPress, there's a plugin that makes it even simpler.
