Annotation Demos

Explore annotating with Hypothesis in the three most widely used formats for published documents: webpages (HTML), PDFs, and EPUBs.

Webpages (HTML)

Annotate any webpage: If you’ve already equipped your browser with Hypothesis, just navigate to a webpage and then activate Hypothesis in your browser to start annotating.

If you don’t have Hypothesis in your browser yet, click on Paste a Link in the menu at the top of this page and type or paste any web address in the box to visit that webpage with Hypothesis enabled.

PDFs

Annotate any PDF: If you’ve already equipped your browser with Hypothesis, just navigate to a PDF online or open any PDF saved on your device using your browser’s File menu, and then activate Hypothesis in your browser to start annotating.

If you don’t have Hypothesis in your browser yet, you can also drag and drop any PDF on the target at docdrop.org to open it with Hypothesis enabled.
