ChatFly

ChatFly lets you build a custom AI chatbot without writing any code. You feed it your data — PDFs, Word documents, Excel sheets, website links, even content from Notion or Google Drive — and it creates a chatbot that answers questions based on that information. It's essentially a private ChatGPT trained on your business knowledge, ready to handle customer support, lead generation, or internal Q&A.

The process is straightforward. You start by connecting your data sources, and ChatFly crawls them to build a knowledge base. Then you tune the bot's behavior: set rules, adjust creativity vs. focus mode so the tone and accuracy match your needs. You can also customize the chatbot's appearance with your brand colors, logo, and even suggested prompts. Finally, you deploy it — either by embedding a widget on your website (a simple script tag), or via API into your own app. It also integrates with Slack, Messenger, WhatsApp, Telegram, Zalo, and Zapier, so it can live wherever your customers are.

This tool is ideal for businesses that want to automate customer support without hiring developers. A support team can reduce repetitive questions, a marketing team can use it for lead capture, and an educational institution can create a virtual assistant for students. The free plan lets you test everything, while paid plans scale from 2 to 10 chatbots and 2,000 to 50,000 message credits per month.
