Research Comments

Your notes and discussions on the paper, private or shared, connected to the paper's DOI across the web.

Read a paper, highlight a passage, add your comment, vote in polls, and share the discussion with anyone. Notes and threads are connected to the paper itself, so they can follow the same article across PubMed, journal websites, preprint servers, and the web. Instead of losing research discussions in emails, chats, screenshots, or scattered notes, Research Comments keeps the conversation next to the paper. With Research Comments, you can: • Comment on research papers while you read • Anchor notes to specific passages, sentences, or figures • Share a full thread or selected comments with one link • Let anyone open shared notes in a normal browser • Read public paper discussions without signing in • Sign in to comment, reply, vote, create polls, and save papers • Vote in article-specific polls and see what others think • Follow activity across comments, likes, votes, polls, and discussions • Create private notes or group discussions • Discuss papers with teams, labs, journal clubs, courses, or collaborators • Save papers into Projects and build a structured research library • Like papers and track activity across public and private discussions • Keep comments connected to the DOI, not just one website URL Research Comments works as a Chrome sidebar and on researchcomments.com. Open the extension on a paper, or use the website to find a paper by DOI, URL, or title. Because comments are linked to the paper’s DOI, the same research discussion can stay unified even when the article appears on different platforms. A paper viewed on PubMed, a journal page, or a preprint server can lead to the same shared thread. Sharing is simple. Copy one link to send the full discussion, or share only the comments that matter. When a comment includes a quoted passage, the context travels with it, so readers understand exactly what part of the paper you are discussing. The activity feed gives Research Comments a social layer for science. See new comments, likes, votes, poll responses, and discussions across papers, so useful insights do not disappear after a paper is closed. Use Research Comments to: • Discuss papers where you already read them • Share research notes without extra setup • Keep feedback attached to the article • Vote on paper-level questions and impressions • Follow what is happening across research discussions • Organize papers by project or topic • Run lightweight paper discussions with others • Build a more connected research workflow Research Comments is built for researchers, students, educators, journal clubs, teams, and anyone who reads scientific literature online.
