  • You want a recorded result for each struggling student and a hand-off to a person.
  • You want students on the same misconception grouped into one live session.

Choose Khanmigo if

  • You want a very large library of lessons, videos and practice already in place.

Where Khanmigo fits

Khanmigo sits on top of Khan Academy’s huge library and its research record, with free tools for teachers and a dedicated writing coach. Zelvi has no library of its own: it teaches from your course’s material and records whether each struggling student recovered.

What our side of this rests on

  • Answers cited back to your own material, with the instructor one tap away when the material does not cover itOn our go/no-go benchmark every answer retrieved the right passage, carried a valid citation and stayed inside the material, and every out-of-scope question routed the learner to the instructor rather than a guess — against 54.2% for handing the model the whole document.
  • About two dozen teaching tools, all from the course’s own material: reading level, translation, feedback, lesson plans, worksheets, rubrics, exit tickets, report comments and family emailsFeedback cites the course pages it relies on, translation keeps the English term beside each subject term, and every pasted text is fenced from the instructions.
  • Students stuck on the same misconception are grouped, and the instructor brings them into one short live sessionGroups are built from the escalations Zelvi already opened, keyed on concept and misconception, and only students enrolled on the course can be invited.
  • See which learners are struggling and which concepts they are stuck onTwenty-nine automated checks on the cohort report, plus five more driven through a real browser.
  • Interactive anatomy diagrams with tap-to-reveal labelling for active recallSix anatomy diagrams ship today, each one a labelling task the learner completes rather than a picture to look at.

Questions people actually ask

Can Khanmigo teach from our own course material?
Khanmigo is built around Khan Academy’s content. Zelvi is built around yours: it reads what your instructor publishes and cites it.
Can a school use both?
Yes. Khan Academy for broad practice on standard topics; Zelvi for a course whose own syllabus decides what must be learned.
