A bigger toolset yields better results & easier content discovery

Harmonize’s full suite of online discussion & collaboration tools provides students and instructors with everything they need to have vibrant online courses, including: image, video & PDF  annotationchatpolls, and Q&A. Content is structured naturally.

When we focus only on annotation, the PDF Annotation features of Harmonize and Hypothesis are essentially the same, as are the video annotation features. For PDFs,  instructors can upload a PDF, and students can comment on it by highlighting and replying to each other’s comments.

Streamlined PDF annotation

Harmonize focuses on a simple, streamlined ability to upload a PDF with minimal instructor set up needed.

  • Harmonize works with any PDF, even if you don’t have proper OCR layers in your PDF, and we also allow dropping pins on visuals in a PDF when there is no text to highlight.
  • When grading in non-Canvas LMSes, we offer comment boxes to submit grade comments back to the LMS gradebook to be more compliant with the new federal RSI guidelines.
  • We allow direct upload of your PDF so instructors don’t have to first upload it to Canvas or Google Drive, which is easier and it doesn’t count against your file storage quotas is those systems.  Harmonize has no storage quota limits.
Save time for instructors

Additional annotation capabilities

Hypothesis does offer the ability to annotate a web page that is outside of the LMS, and it also provides the ability for students to take their own private note annotations that aren’t shared for collaboration purposes with their classmates.
