Paper Reader lets users explain passages, formulas and citations inside research papers
tumanian · reddit · 2026-07-22
A user built Paper Reader, a web tool that lets readers highlight a passage, formula, figure, or citation inside a research paper and get an explanation with the full paper as context. The tool is meant to reduce the back-and-forth of copying text into Claude, and the author says it is built with Claude, Cursor, Vercel, and Supabase, running on a personal API key with a modest usage cap. The post asks for feedback, especially on whether the explanations are accurate or useful.
