# SummarizePaper

> SummarizePaper (summarizepaper.com) publishes AI summaries of research papers from arXiv, open-access journals (any DOI) and preprint servers (bioRxiv, medRxiv, HAL, ChemRxiv, PsyArXiv and the other OSF servers, Europe PMC), in English and French, with rewrites in 16 languages and four reading levels. Each paper page gives a detailed summary, the key points, a lay summary anyone can understand, a blog-style article, related papers and the BibTeX entry, generated from the full text of the paper when its license allows it (CC BY, BY-SA, BY-NC, BY-NC-SA, CC0), from its abstract otherwise. Its AI assistant answers from the full text and figures of one or several papers and, after each answer, lists its claims with the sentence of the paper that supports each one, checked word for word, and a link to that passage. Around the summaries, research tools help follow a field, check a draft before submission, review the literature on a research question and prepare a journal club or a press kit. It is free to read and is run by an astrophysics researcher, Quentin Kral.

Paper pages follow the pattern `https://www.summarizepaper.com/<lang>/paper/<id>/`, where `<lang>` is `en` or `fr` and `<id>` is an arXiv ID (https://www.summarizepaper.com/en/paper/2302.13303v1/) or, for other sources, `doi_` followed by the DOI with `/` written `--` (https://www.summarizepaper.com/en/paper/doi_10.1093--mnras--stad1234/). Older `/arxiv-id/` addresses redirect there. Every summarized paper is listed in the sitemap. Summaries are produced by OpenAI language models from the version published by arXiv, the publisher or the preprint server; the original paper remains the reference.
