Is it permissible to sell a home-schooling plan for children that was created by artificial intelligence with modifications made to it, and what are the regulations for pricing in this case?

There is no objection to using artificial intelligence or other legitimate means in the plan, as what is important is the safety of the final content from Shariah prohibitions, its correctness, and its conformity to what it is marketed as. This can be achieved through review and scrutiny or by presenting it to specialists. As for price determination, there is no Shariah limit for it, so whatever the buyer and seller agree upon makes the sale valid, according to the Almighty’s saying: "O you who have believed, do not consume one another's properties wrongfully except by trade [involving mutual consent] from among you," and the Prophet's (peace be upon him) saying: "Indeed, selling is only by mutual consent." In terms of virtue and reward, gentleness, tolerance, and sincere advice are better than abundant profit.
