AI Tutor Apps Compared 2026: ChatGPT vs Gemini vs Khanmigo

Three of the biggest names in AI just added a mode that refuses to just give you the answer. ChatGPT has Study Mode. Gemini has Guided Learning. Khan Academy's Khanmigo just got a Gemini-powered upgrade for the 2026 school year, with interactive diagrams and a teacher-controlled practice tool.

They all promise the same thing: to act more like a tutor and less like a search engine. But they work differently, cost different amounts of effort to access, and fit different situations. Here's what each one actually does, and where a no-login tool still beats all three.


What "Guided" Actually Means, vs. a Regular Chatbot

A normal AI chat answers your question directly. Ask it to solve an equation, and it solves the equation. That's fast, but it doesn't teach you anything if you never see the steps.

A guided mode is built to slow that down on purpose. Instead of a final answer, it asks you a question back, breaks the problem into smaller steps, checks whether you actually understood the last step, and only moves forward once you have.

It's closer to how a patient human tutor works through a problem with you.


ChatGPT Study Mode

OpenAI launched Study Mode in 2025 and built it with teachers and learning scientists. Turn it on from the tools menu in any chat, and instead of a direct answer you get Socratic questions, explanations broken into digestible sections, and short knowledge checks along the way.

It's available to logged-in users on ChatGPT's Free, Plus, Pro, and Team plans, so you do need an account, but not a paid one.

Where it falls short

Study Mode is a setting, not a different model, so it runs on custom instructions rather than being built into the AI from the ground up. That means its behavior can be inconsistent, and you can simply switch it off mid-conversation and get a direct answer anyway.

It also wasn't designed specifically for K-12 students. OpenAI has said it's researching K-12 use with Stanford, so treat it as a study tool built with teenagers and adults in mind, not younger kids.


Gemini Guided Learning

Guided Learning is a free mode inside the Gemini app. Google built it on LearnLM, a family of models tuned specifically for teaching rather than general conversation, using research done with educators and learning scientists.

Instead of an answer, it asks open-ended questions, breaks a topic into steps, and adapts its explanation to what you already seem to understand. It can also respond with images, diagrams, or short quizzes, not just text.

You just need a Google account to use it, and teachers can share a Guided Learning link directly into Google Classroom.


Khanmigo's New Gemini-Powered Features

Khan Academy's Khanmigo isn't a chatbot mode you toggle, it's a full AI tutor product that schools and districts sign up for. For the 2026 school year, it picked up two new features built with Google.org over a six-month collaboration.

Interactive visual tutoring

Khanmigo can now generate diagrams, charts, and geometric shapes for math and science problems. Students can actually manipulate them, dragging a vertex or a line segment, and the diagram updates in real time.

Khan Academy says early classroom testing showed better engagement and stronger results on the next problem students tried on their own afterward. It's a similar idea to the step-by-step visuals in our own AI Science Solver, just built into Khanmigo's own product.

Practice My Knowledge, rebuilt for teachers

Teachers can now have Gemini draft multiple-choice practice questions from their own material, then review, edit, or reject each one before it ever reaches a student. The teacher stays in control of exactly what gets assigned.

Both features only work if your school already uses Khanmigo. There's no way for an individual student to sign up for it on their own.


A Prompt That Works in Any of the Three

If you want to test whether a guided mode is actually helping you instead of just answering slower, try a prompt like this in any of them:

"Walk me through the quadratic formula on this problem, but don't give me the final answer until I've told you what I think the next step is."

A tool that's actually built for guided learning will hold back the answer and check your reasoning first. One that isn't will usually just solve it anyway.


What Parents Should Know

If your kid's school already pays for Khanmigo, that's the one with adult oversight built in. Teachers see and approve the practice questions before students do, and it only runs inside a school-managed account, not a personal app your child downloaded on their own.

ChatGPT and Gemini are different. Both are general consumer apps your child could already have on their phone, and Study Mode or Guided Learning is just a setting inside them, not a separate, monitored product.

Conversations in ChatGPT can be stored and, unless you turn on extra privacy settings, used to improve OpenAI's models. It's worth checking each app's current data and account-age settings yourself before treating either one as a school-safe tool for a younger child.


Guided vs. Answer-Only, Side by Side

  • ChatGPT Study Mode: needs a free ChatGPT account, works across any subject, best for high schoolers and college students who already use ChatGPT.
  • Gemini Guided Learning: needs a free Google account, free to use, works across any subject, includes diagrams and quizzes.
  • Khanmigo: only available through a school or district subscription, strongest for math and science with the new interactive diagrams.
  • AI Homework Helper: no account, no sign-up, works the moment the page loads, with dedicated tools for math, science, and English.

Where a No-Login Tool Still Fits

All three tools above ask for something before you can use them: an account, a subscription, or a school that already pays for one. That's a real barrier on a Tuesday night when you just need to get unstuck.

AI Homework Helper skips all of that. There's no sign-up, and the AI Math Solver and other subject tools walk you through a problem step by step the same way a guided mode does, just without needing an account first.

If you're already comfortable prompting an AI well, the guide on how to use AI Homework Helper covers how to phrase questions so you get an explanation instead of a bare answer, in any of these tools.

The premium plan adds structured study tools on top, like Quiz Me, Flashcards, and a Countdown Planner for test prep, for students who want more than a step-by-step explainer.


How to Pick, by Situation

If your school already uses Khanmigo, use it for math and science, that's what its new diagram tool was built for.

If you're in high school or college and already have a ChatGPT or Google account, Study Mode or Guided Learning both work well as a free add-on to something you're already using.

If you just need help right now and don't want to create an account or wait on your school's rollout, a no-login tool gets you unstuck immediately.

That matters more than it sounds like: the moment you have to stop, sign up, and remember a password is usually the moment you give up and just copy an answer from somewhere else instead.

None of this is really about which company built the best chatbot. It's about which one you can actually reach at 9pm on a school night, in the subject you're stuck on, without extra steps in the way.

The Catch With All Four

A guided mode makes it harder to get a lazy answer, but it doesn't make the AI right. Any of these tools can still get a fact, date, or formula wrong with total confidence.

Always check the final result against your textbook or teacher before you turn it in.


Frequently Asked Questions

What is Gemini Guided Learning and is it free?

Guided Learning is a mode inside the Gemini app that asks you questions and breaks problems into steps instead of giving a straight answer.

It's free to use inside the Gemini app and is built on Google's LearnLM models, which are tuned specifically for teaching rather than general chat.

What is ChatGPT Study Mode and how does it work?

Study Mode is a setting inside ChatGPT that uses Socratic questions, scaffolded explanations, and short knowledge checks instead of handing you a finished answer. OpenAI built it with teachers and learning scientists, and you turn it on or off through the tools menu in any chat.

It's available to logged-in users on ChatGPT's Free, Plus, Pro, and Team plans.

What did Khanmigo change with Gemini in 2026?

For the 2026 school year, Khan Academy added Gemini-powered interactive diagrams that students can drag and adjust in math and science problems, plus a redesigned tool that lets teachers generate practice questions with AI and edit or reject them before students see them.

Both came out of a six-month project between Khan Academy and Google.org.

Do I need an account or does my school need to sign up?

Yes for all three. ChatGPT Study Mode needs a logged-in ChatGPT account, Gemini Guided Learning needs a Google account, and Khanmigo's new features only work for schools and districts already signed up for Khan Academy's Khanmigo product.

A tool like AI Homework Helper skips this step entirely and works with no sign-up at all.

Which AI tutor is best for math homework?

If your school already uses Khanmigo, its new interactive diagrams are built specifically for math and science and let you manipulate the shape or graph as part of solving the problem.

If you don't have school access, Gemini Guided Learning and ChatGPT Study Mode both work for math, but neither draws an interactive diagram the way Khanmigo now does.

Is using an AI tutor mode considered cheating?

No. These modes are built to make you do more of the thinking, not less, which is the opposite of having AI do your homework for you.

It only becomes an integrity problem if you turn the guided mode off, get a straight answer, and submit it as your own work without understanding it.

Is Khanmigo, ChatGPT, or Gemini safer for a younger child?

Khanmigo has the most built-in oversight for younger students, since it only runs through a school-managed account and teachers approve the practice content.

ChatGPT and Gemini are general consumer apps with a study setting inside them, not school-monitored products, so check each one's current privacy and data settings before treating them as school-safe for a younger child.
