Paperchecker
Paperchecker is a command-line AI paper agent that runs locally to review research papers while protecting user privacy.
Paperchecker is a light command-line interface agent designed to help users review and query their own research papers locally. It runs on Linux and uses local tools and paper retrieval to answer questions based on user-provided documents. Users can place text-based PDF, Markdown, or text files into a designated knowledge folder and build indexes for retrieval. The default model is Qwen3-14B-AWQ, and the system supports the Model Context Protocol for tool registration. It saves session history to markdown files and supports optional checkpointing.
