PaperLab: An Overleaf-like Workbench for Iterative Paper Revision

PaperLab is an Overleaf-style paper iteration workspace integrating DeepSeek Harness (dsh). It aims to address the fragmentation of PDF annotations, LaTeX source code editing, compilation results, and Git history, integrating "reading, annotating, editing, viewing PDFs, and rolling back versions" into a unified workflow. Its core features include a three-column interface that supports precise annotation on the rendered real PDF; an AI revision workflow based on the dsh agent that automatically executes "read annotation - edit source - compile check - Git commit" and provides real-time trajectory monitoring; and complete version management, supporting history browsing, Diff comparison, and one-click rollback. PaperLab does not directly invoke model APIs; all AI executions are completed within the dsh environment, ensuring model credentials are secure.
