I never thought I’d say this, but we can literally chat with PDFs now. Thanks to tools like LangChain, static documents are becoming interactive. You upload a PDF, hook it up with ChatGPT through LangChain, and suddenly you’re having an intelligent conversation with the content—asking questions and getting clear, context-aware answers, almost like talking to a subject-matter expert. Now imagine combining that level of smart interaction with real-time communication inside your app. That’s where Sceyt comes in.
