MyProMind vs Qedra

Adaptive Courses Drop in a syllabus, slide deck or video. ProMind structures content into recall-ready blocks and generates aligned questions instantly. Every learner gets a path tuned to what they already know. Spaced Repetition ProMind's FSRS engine tracks how well you know each concept across courses and assessments, scheduling reviews at the optimal moment, right before you'd forget. Study less, retain more. Assignments & Groups Assign practice sets, conversational checks, or full-length exams to a class, cohort, or department. Track completion, mastery, and where each learner is stuck in one live view. Deep Analytics Nine views into learning, live. Engagement, effectiveness, mastery, velocity, predictions. For cohorts and individuals. Catch the slip before the test does. AI Tutor A 1-on-1 conversational examiner grounded in your course content. Adapts in real time, scores per question, asks follow-ups, and re-tests gaps until mastery is genuine. Learning Marketplace Thousands of curated, vetted decks across subjects, languages, and corporate domains. Fork them, remix them, ship them to your learners in a click.

Work through supported calculus, algebra and matrix problems offline, with exact answers and steps you can follow. Qedra brings university mathematics to your iPhone and iPad. Calculations run on your device, even in airplane mode. No account is needed. BUILD THE PROBLEM YOU MEAN Enter derivatives, integrals and limits with guided fields. Use a matrix grid for determinants, inverses, row reduction, rank and eigenvalues. Check the live preview before solving, or type directly with the mathematics keyboard. UNDERSTAND THE WORKING Open a step to read its named rule, explanation and assumptions. Fractions stay exact. Where a verification check is available, Qedra shows its result and limitations. Some inputs remain symbolic or receive a method-limit explanation. KEEP YOUR REVISION NOTES Save useful problems in a course notebook, add your own notes and labels, search your collection and mark topics to revisit. Saved problems keep their original notation, operation and real or complex setting. Notebooks stay on this device. PRACTISE WITH HINTS Try a problem yourself, ask for a hint and reveal the solution one step at a time. Supported practice topics include power-rule derivatives, polynomial integrals, integration by parts, 2 × 2 determinants and linear equations. Scratch work is not automatically graded. MATHEMATICS FOR YOUR COURSEWORK - Algebra, equations and inequalities - Limits, derivatives and supported integrals - Partial derivatives, multiple integrals and vector calculus - Exact determinants, inverses, row reduction, rank and eigenvalues - Discrete mathematics, probability and statistics - Complex arithmetic Decimal-comma input, notation settings, a rule reference library and translated explanations help you follow the mathematics in your own way. START WITH THE FREE TIER Get unlimited answers, three full worked solutions per day, the most recent 100 unpinned history entries, one course notebook and one practice example per topic. Pinned history stays until you delete it. Text sharing and copying answers as LaTeX are included. The free tier can show a banner on the Solve screen. QEDRA PRO Pro adds unlimited worked solutions and history, more course notebooks, additional practice variations, formatted solution PDF export and no ads.
