Hello, I am looking for an LMS app for Open edX like the Hypothes.is app for many other LMS [Hypothesis in Your LMS : Hypothesis](https://web.hypothes.is/education/lms/) ?

@palml If Hypothes.is supports LTI, you might be able to embed it in Open edX?

Otherwise, there are at least two other options currently for Open edX:

1. The **Notes Tool** , which is a supported tool part of the official Open edX distribution:

1. **The HarvardX Annotation Tool (HxAT)**, an annotation tool developed by HarvardX - we currently manage an instance of it for some of OpenCraft’s clients:

> **[lduarte1991/hxat - The HarvardX Annotation Tool (HxAT)](https://github.com/lduarte1991/hxat#the-harvardx-annotation-tool-hxat)**
>
> Contains the currently-in-development project by HarvardX to bring the annotation tool currently living in the edX platform to a more accessible LTI implementation.

> **[Annotation tools supported by HUIT Academic Technology](https://atg.fas.harvard.edu/annotation#annoX)**
>
> Academic Technology for FAS currently supports two annotation-related toolsets that can be added to Canvas course sites. Click below to learn more about each, and contact atg@fas.harvard.edu with any questions.
