Unofficial Hypothesis extension автор Diego de la Hera

This unofficial extension let's you use Hypothesis to collaboratively annotate, highlight, and tag web pages and PDF documents.

Use it to hold discussions, read socially, organize your research, and take personal notes on webpages, PDFs and EPUBs.

This is an unofficial extension and it is not endorsed by Hypothesis.

Once installed, click on the extension's button to see public annotations on the websites you visit. Log in to your Hypothesis account to make your own public and private annotations.

- Select text to annotate. Add tags and post publicly or save privately.
- Reply to or share any annotation. Link to notes or whole pages.
- Annotate together in groups. Collaborate privately with others.
- Search your notes. Explore all public annotations and profiles.

Hypothesis does not monitor, track or collect any of your personal data beyond what is necessary for creating, saving and reading your annotations. See the privacy policy for more information.
