Dropchat is an AI tool that lets you chat with information in various formats, like books, websites, and even videos. Imagine having a conversation with a PDF document to understand its content or asking a YouTube video questions about its topic. Dropchat uses AI to analyze the information you provide and then builds a chatbot that can answer your questions in a conversational way. It also offers a private library to save your chatbots and documents for future use, and even creates a “second brain” system where you can revisit key points through notes and flashcards.
