There are several platforms where people can discuss arXiv papers and provide reviews or comments:
-
alphaXiv: Developed by Stanford AI Lab students, alphaXiv is an open discussion forum for arXiv papers. Users can post questions and comments directly on any arXiv paper by changing "arXiv" to "alphaXiv" in the URL[1][3].
-
Hugging Face: This platform allows users to comment on arXiv papers, providing a space for discussion and feedback[2].
-
SciRate: A site that enables users to rate and comment on papers from arXiv[5].
-
PubPeer: While not specifically for arXiv papers, PubPeer follows a similar model, allowing community-driven peer review and discussions on scientific publications[3].
-
bioRxiv: Although not for all arXiv papers, bioRxiv (for biology preprints) includes a comment section for discussions[2].
These platforms aim to foster open dialogue, critical analysis, and collaboration among researchers. However, it's worth noting that arXiv itself does not have a built-in comment section, as it focuses primarily on its core mission of rapid dissemination of scholarly papers[2][7].
The adoption and activity levels on these platforms can vary. While some, like alphaXiv, are gaining popularity in certain fields (e.g., AI/ML), they may not be as well-known or widely used in other disciplines[3]. The effectiveness of these discussion forums depends on the engagement of the research community and the quality of the discussions they generate.

Based on the search results, we can rank some of the systems for discussing arXiv papers by their apparent popularity or usage. Here's an approximate ranking:
Hugging Face: This platform appears to be the most widely used, with over a million models, datasets, and apps[3]. It allows users to comment on arXiv papers and has attracted attention from major tech companies[3][7].
Reddit: While not specifically for arXiv papers, Reddit has numerous subreddits where people discuss scientific papers, including those from arXiv. For example, r/MachineLearning has discussions about arXiv papers[4].
arXiv Sanity Preserver: This platform is mentioned as a tool for keeping up with machine learning papers from arXiv[4].
alphaXiv: This is a newer platform specifically designed for open research discussion on top of arXiv. While it's gaining traction, it's not as established as the above options[11].
SciRate: Mentioned as one of the social media sites built around arXiv for commenting and rating papers[7].
It's important to note that arXiv itself doesn't have a built-in comment section. A 2016 survey showed mixed opinions among users about whether arXiv should incorporate social features like commenting, with only 34% in favor of such changes[7].
