Epsilon PDF viewer

The PDF reader for scientific papers: search formulas as you type them, copy them as LaTeX, peek at links. Fill and sign too.

Epsilon PDF viewer: the PDF reader made for scientific papers. ★ SEARCH FORMULAS, NOT JUST WORDS Type a formula into the find bar, in LaTeX (\alpha_1) or plain (alpha_1). Epsilon finds every place it appears, however the authors typed it, and highlights exactly its symbols. ★ PEEK AT ANY LINK WITHOUT LOSING YOUR PLACE A link to an equation, figure, section or citation opens in a panel below, its target marked. Your page stays where it is. Cmd/Ctrl + click a link to peek. ★ SELECT BY FORMULA, COPY AS LATEX The selection follows the formula's structure: drag into a fraction or a bracket and it is taken whole. Copy, and you get LaTeX, ready for your notes or your next paper. ★ MOVE THROUGH THE PAPER, AND BACK The outline shows every section, the one you are reading marked. Jump to any of them; Back takes you to where you were. ★ WORKS WITH EVERY JOURNAL Whoever the publisher, Epsilon reads the formulas in its papers: search them, select them, copy them. ★ EVERYTHING YOU EXPECT FROM A PDF READER • Any PDF, on the web or on your computer • Highlight the passages that matter • Add text anywhere on the page • Draw, freehand, on any page • Sign: type, draw or upload your signature • Fill in forms, right in the viewer • Print it, or save a copy • Presentation mode: full screen, page by page • Your look: Epsilon's or Chrome's, in light or dark ★ YOUR PAPERS STAY WITH YOU Everything runs in your browser.
