Pros	Built on widely adopted open-source Mermaid syntax Diagrams stay portable and diff-able AI lowers the barrier to the syntax Real-time collaboration and a visual editor Integrates natively with many docs and code tools	Question-by-question grading with dynamic rubrics lets instructors score one question across an entire class and retroactively apply rubric changes, producing far more consistent feedback than grading paper by paper. Answer grouping and template overlay surface identical or near-identical responses so common answers can be scored in bulk, which meaningfully cuts grading time on large sections. The built-in code autograder runs student submissions against test cases and pairs automated results with manual style review, making it genuinely useful for computer science and engineering courses. Strong support for the full assessment lifecycle, including bubble sheet processing, assignment statistics, item analytics, and a structured regrade request workflow that keeps disputes organized. A free Basic plan gives individual instructors real functionality, lowering the barrier to trying the platform before an institution commits.
Cons	Syntax-first approach is not for everyone Pricing transparency varies across sources Higher tiers described as increasingly sales-led No native mobile app Single-language interface focus	Pricing is not fully transparent: the most powerful features and collaborative grading sit behind Institutional licensing that requires contacting sales, so what you actually pay varies by enrollment and negotiated terms. AI-powered and collaborative grading are gated to paid or institutional tiers, meaning solo instructors on the free Basic plan miss some of the platform's most time-saving capabilities. Setting up rubrics, autograder configurations, and scan workflows involves an initial learning curve, and getting the most value requires up-front effort per assignment. It is purpose-built for grading assessments rather than a general LMS, so institutions still need separate tools for course delivery, communication, and content hosting.
