Lacuna by Tiptree Systems
Lacuna by Tiptree Systems is a research tool that maps a GitHub repository's Python code to the academic papers it relies on.
Lacuna by Tiptree Systems is a research tool designed for developers and researchers to trace the academic origins of a GitHub repository's code. Users paste a GitHub repository URL, and the tool reads the Python code, including imports, function calls, loaded models, and citations in comments and the README. It matches each code element to the corresponding research paper and provides a one-line key idea for each paper. Users can dig backward from any paper or use the Tree view to trace ideas to earlier foundational work, sometimes dating back a century. The system uses Claude and Codex AI models to select papers and links, verifying each connection against Lacuna, where solid lines indicate agreement between both models and dashed lines show a single model selection. Users can export all findings in BibTeX, CSV, or Markdown formats.
