24 alternatives to Comments on Science
Comments on Science is a free and public user-generated database of scientific comments. Commenting on papers in academic journals is a complicated process, with many steps between an idea for a comment and the appearance of that comment in a (mostly closed-access) publication. The goal of Comments on Science is to reduce this friction and enable accessible and free scientific communication. About the site: I decided to build something useful in the month of May and this is what I made. It has a few features like following (users, papers, or comments), tagging, voting, etc. It was a nice…

One year ago I open-sourced my very first 'real' project and shared it here. I was a college student in my senior year and desperately looking for a job. At the time of sharing it i couldn't even afford a domain and naively let someone buy the one i had my eyes on lol. It's been a hell of a year with this blowing up, me moving to another country, and switching 2 jobs. In a year we somehow managed to hit 26k stars, grow a 1000+ person discord community, and support 37 languages. I couldn't be more grateful for the community that helped this grow, but now i don't know what direction to take…

Key features: 24 specialized agents analyzing sections, scientific rigor, and writing quality // Detailed feedback with actionable recommendations. // PDF report generation. //…

Commentblocks▲101Hey HN, I'm a freelance web developer and got tired of the endless email chains during website QA. Clients would send screenshots with red circles, or worse, Word docs with "the button on the page with the thing." I'd spend more time decoding feedback than actually fixing stuff. So I built Commentblocks. You add a script to your staging site, send clients a link, and they click anywhere on the page to leave a comment. That's it. No signup for them, no explaining how to use it. Each comment captures the exact element, viewport size, browser, and URL. Comments show up in a dashboard or can go…

http://paperkast.com Hello everybody, I just wanted to share a link aggregator website: paperkast.com. It's a article sharing and discussion hub. It's opened recently. I think it was a need for the academia. I don't think there is an online community for paper discussion. Twitter is good for publication sharing but there is no central discussion around a paper. It's all over the place. Seperately, we know that the link aggregation style has a good reputation. It's a good stimulation for discussion. What do you think of it?
