Möbius Assessment vs TAO

Möbius Assessment provides online homework and assessment capabilities for mathematics and STEM courses. Its math engine supports complex STEM learning and math autograding, while the platform offers 15 question types, from multiple choice to open-ended responses. Assessments can use algorithmically generated and randomized questions for homework, placement, proctored, or adaptive tests. With Show your work, instructors can award partial credit when a final answer is wrong. Educators can configure more than 50 assignment properties, including scheduling, feedback, access conditions, and security. Assignments can guide students through different learning paths, reinforce content, or revisit earlier objectives; students receive immediate feedback and instructors get engagement and understanding data. Möbius integrates with Canvas, Moodle, Blackboard, and Brightspace, including single sign-on and grade syncing. It is certified for LTI 1.3 Core and supports LTI Advantage Deep Linking. DigitalEd describes the environment as mobile-ready and lists Android, iOS, Linux, macOS, web, and Windows. Pricing is available by request. DigitalEd says versions older than 12 months are unsupported.
