Not arXiv. arXivv is an independent experiment and is not affiliated with, endorsed by, or operated by arXiv or Cornell University. The name was chosen for convenience: swap one letter in an arXiv URL. arXiv is a registered trademark of Cornell University.

arXivv

The missing data layer for arXiv, built for AI and LLMs. Every arXiv paper as Markdown, JSON and plain text, plus an MCP server, served from the URLs you already use.

Two rules

1. Drop-in: swap arxiv.org for arxivv.org and every arXiv path keeps working.
2. Our formats: add an extension to a paper id.
