The TsugiCloud App Store hosts a number of free LTI tools including a peer grading tool, a GIFT based quiz engine, writing prompt tool, a youtube launcher with analytics and grades, and many other tools. By installing the App store in any LMS that supports Content Item you can quickly search for and install the tools in the TsugiCloud store. In addition to LMS systems, TsugiCloud tools can be integrated into Google Classroom.
