Khan Academy's Socratic tutor that guides students toward answers rather than supplying them.
What it is good at
Deliberately designed not to give answers — it asks guiding questions, which is the opposite design choice from every other solver here and makes it the only one that is integrity-aligned by construction. Backed by a nonprofit with no advertising model, and the free teacher tier is real and usable.
Use it for
Analyzing Khanmigo's scaffolding moves against Vygotskian zone-of-proximal-development theory, identifying where the tutor does and does not hand over cognitive work. Assigning tutoring on prerequisite gaps for co-requisite students so class time stays on college-level content.
Where it falls short
Content ceiling is roughly algebra 2 and precalculus, and the platform is not marketed or licensed for higher education — it fits developmental and co-requisite math and nothing above it. Learners under 18 require a parent or guardian to sign up on their behalf, which blocks direct assignment in dual-enrollment sections. Adult students sometimes react poorly to a tool visibly built for high schoolers.
