About

Upload files or add website URLs, a GPT chatbot will be built for you that can answer any questions about your content in real-time. Boost your chatbot's performance by training it on a range of data types, such as text, PDFs, and website URLs. You can use all 3 data types at once. Custom Q&A allows you to guide your chatbot in addressing questions that it may not be answering correctly or completely. ChatFast stands out from the crowd with the ability to ask for visitor information using natural language at the perfect moment. This is important because you don't want to miss out on getting important leads. Always stay in the loop with chat transcripts and new contact information sent to your email address. Webhook is also available to directly transfer your contacts to your favorite CRM in real-time. Simply enable public access for the chatbot and include the provided script in either the body or footer of your website (such as WordPress, Shopify, etc.).
