Sign up for an account; create a workspace for storing documents; upload some PDF documents; highlight text to add a comment; share your workspace with other people to let them add their feedback. The QuickStart section of the user guide should help you get started.

You can go through an animated guide which comes in a tutorial form. The QuickStart section of the user guide should help you get started. Click the 'full text/animated' toggle in the top left to see some animated screenshots.

No, it only uses standard browser features. You do not have to install anything else.

All your documents and notes are stored in a workspace, and can only be accessed by people you invite. You can also set user roles, to grant some people view-only permission, and allow others to upload their documents to the workspace too. All documents and notes are served via HTTPS which ensures the data is encrypted over the internet. Regular off-site backups help keep your data safe. We can also arrange for a private server for your company, and behind-the-firewall installations for particularly sensitive documents.

You can print the web page to a PDF file using your browser, and upload the PDF to annotate.co. We plan to have a smoother solution in future.

Not yet, but if you'd like it in a particular language, please get in touch. It supports documents and annotations written in any language. We may be able to offer a free subscription in return for translations of the language files.

The basic document viewing functions work in iPad and Android, and there is basic annotation support on iPad too. We are working on an improved annotation interface which should make it smoother to make notes with a tablet.

Back in 2005, the two founders were doing postdoctoral research in computational neuroscience, and were looking for ways to get structured access to experimental data. Almost everything is published as text, but there are far too many research papers for any individual to read. Rather than expecting scientists to change their behavior and create databases directly, they began investigating ways for authors to layer structured information on top of written text. After a number of iterations, this led to the first version of annotate.co. With the benefit of extensive feedback from users, the focus gradually shifted from complex structured annotations to collaborative discussion around the text, as seen in the present version of annotate.co.
The ease of building up a structured index of notes across large numbers of documents reflects the software's origins in annotating scientific data and papers, and now finds applications in a wide range of areas where in-depth discussion on a collection of documents is needed - from lawyers discussing thousands of evidence documents related to a court case, to medical experts analysing research papers and textbooks, to product marketing specialists and engineers checking technical details in marketing materials - as well as original target of students and researchers discussing papers.

Yes, please do. If you use Moodle, then our Moodle plugin may be of interest. It synchronizes accounts and learning materials from Moodle into annotate. We also have a Blackboard building block and an LTI endpoint for easy connection to many learning management systems including Canvas. If your requirements do not fit well within the current structure based on shared workspaces then we'd love to hear from you. Just let us know.

Yes, see the Annotate API Documentation. The API can be used to connect an external document management system to a dedicated installation of Annotate.co. It connects with a separate server running annotate.co just for your or your company's use.

Yes, there is a restricted version for each of the premium features that you can try with a free subscription. They are normally limited by the number of notes or pages that will be displayed.

No, you can cancel at any time and no more payments will be taken. At the end of the period you have paid for, your account will be downgraded to a free account.

Yes - see the Annotate Private Cloud page for details of how we can arrange a dedicated installation of annotate.co on a private server for your company, with custom branding and logos. For larger enterprise customers we can also install in-house on company servers, and help integrate with company systems using our API.
