Read PDFs

Install the extension, then look up words in any PDF

Papers, reports, ebooks. Words you looked up light up on later pages, and reviews take you back to the page you found them on. Files never leave your computer.

A PDF paper open in Echo's reader, with the recall card for “attention”, looked up on page 3

Opening each kind of PDF

PDFs on the web

Just open them. If you chose “Read PDFs”, Echo opens them for you; otherwise click “Open this PDF in Echo” at the bottom right, and after the first time Echo asks whether to always do it. “Open in browser” is always at the top.

PDFs on your computer

Drag the file into Echo's reader, or click “Open a PDF file” in the toolbar popup. The first time, turn on “Allow access to file URLs” in the extension's settings so reviews can take you back to the page.

Scanned PDFs

A PDF made of images has no text, so words can't be looked up yet. Echo says so and offers “Open in browser”.
