ChatGPT is an AI tool based on Letterdrop that can be integrated into websites, allowing visitors to ask questions and receive helpful answers based on the content of guides, blogs, and resource pages. It can handle queries on any topic covered in the website's content, using semantic search technology to understand the intent behind user queries and assist them in quickly and accurately finding the information they need.

ChatGPT can serve as a complement to traditional keyword-based search widgets, allowing users to ask natural questions using simple language. This tool can also assist marketing and support teams in efficiently addressing customer queries and quickly directing them to relevant content. ChatGPT offers a free limited service, capable of handling up to 20 queries per hour. Paid accounts provide additional benefits, including continuous indexing of new content, making it easier to update the chatbot with the latest information. Users can also access the Slack integration of Letterdrop, enabling team members to ask real-time questions about the content directly from Slack.
