Khanmigo or Photomath?
Photomath is free, solves from a photo and only does maths. Khanmigo costs $4/month, covers more subjects and, above all, does not give the answer: it guides with questions until the student gets there alone. If the goal is handing in homework, Photomath; if it is learning, Khanmigo.

The differences that actually matter
Teaching the method or solving the exercise
Photomath solves and shows the steps; Khanmigo refuses to solve and guides you with questions instead. The difference is not quality but pedagogical intent, and it completely determines what the user learns.
Subject coverage
Photomath does maths and little else, in great depth. Khanmigo covers Khan Academy's whole catalogue: maths, science, history, economics. If the problem is only maths, the specialist is enough; if it spans several subjects, it is not.
Speed versus learning
Photomath solves in seconds, and that is exactly its virtue and its risk. Khanmigo takes longer because the process is the product. Which suits you depends on whether the priority is handing in homework today or passing the exam in a month.
Frequently asked questions
Which should I recommend to my child?
Khanmigo, if the goal is learning, because it does not hand over the shortcut. Photomath can help as support once they have tried and want to see the correct procedure. The problem is not the tool but using it before attempting the exercise.
Does Photomath explain or just give the answer?
It shows the working step by step, not just the final number, and that is its most valuable part. Even so, reading a correct procedure is not the same as producing one: to consolidate you have to redo it without looking.
