Fully Local Pdf Chatbot
This project is a private document analysis tool that enables conversational interaction with PDF files by executing all language model inference and processing entirely on the local machine. By running models directly within the browser or local environment, it ensures that sensitive user data remains offline and inaccessible to external servers or third-party cloud providers.
The system utilizes retrieval augmented generation to provide context-aware answers, supported by local document text extraction and vector embedding indexing. This architecture allows for semantic search and information retrieval without relying on external database services or internet connectivity.
Beyond core conversational capabilities, the tool includes observability features that log the internal steps of model reasoning and retrieval chains. This execution tracing allows for the debugging of performance issues and the optimization of response quality during the document analysis process.
Features
