MathaCarta — arXiv Explorer

MathaCarta helps you discover mathematical research while you read. Highlight a theorem name, mathematical topic, or author on a webpage, and MathaCarta automatically searches arXiv and displays the number of matching articles, article titles, author names, and links. MathaCarta also includes a PDF reading mode. Open a local PDF or an online PDF, highlight selectable text, and search arXiv without leaving the reader. Features: • Automatic arXiv searches from highlighted text • Author and theorem/topic search modes • Article counts and links to arXiv papers • Selectable-text PDF reading mode • Right-click option to open a PDF in MathaCarta • Local caching to reduce repeated searches • No account required • No AI service • No analytics Search results are based on arXiv title, abstract, or author metadata. Counts are query matches and do not verify that a theorem is mentioned in the full text. Author-name matching is heuristic, so common names may produce mixed results. MathaCarta sends selected search text to arXiv when a search is triggered. Local PDFs are processed on your device. Online PDFs are retrieved from their original host after you approve access.
