How they differ
Inline highlighting vs whole-paper structure
Explainpaper is well known for the highlight-to-explain interaction: you select a confusing sentence or term and get an explanation in place. arxvi instead produces a structured breakdown of a whole paper or section — problem, method, key equations in plain language, results, and a summary — which suits scanning and note-taking. Both reduce jargon; they just work at different granularities.
Reading in your language
arxvi provides a full multilingual interface and a dedicated translator that keeps equations and citations intact, plus a bilingual glossary. As of 2026, Explainpaper focuses on English explanations rather than translation, so arxvi is the stronger fit if you want to read papers in Chinese, Japanese, Korean, Spanish, or German.
