AI tutor vs ChatGPT for homework: what a chat window cannot do
ChatGPT is a general-purpose chat assistant that works from what you paste, and for a quick second explanation it is often enough. A purpose-built AI tutor differs in four checkable ways: it watches the page or screen you are working on as you work, it reads your assignment and rubric, it draws the working out while it talks, and it is designed to make you do the next step rather than hand over the answer. For homework that will be graded, those four are the difference between help and a shortcut.

What is ChatGPT good at for homework?
Breadth and familiarity. ChatGPT will explain almost any concept at almost any level, rephrase a textbook paragraph three different ways, and answer follow-up questions without complaint. Most students already have it open, which is not a small advantage: the tool you actually use beats the tool you meant to set up.
What can a chat window not do?
Four things, each of which you can verify in a session rather than take on trust.
- It has never read your rubric. A general assistant answers the question you typed. It does not know that your marker awards most of the marks for the method, or that two criteria on the rubric are the same thing said twice.
- It works from what you paste. A live session that watches your shared screen or your camera sees the wrong step as you write it, not after.
- It does not draw. An explanation of a geometry construction or a free-body diagram in a block of text is a poor substitute for watching it drawn.
- It has no reason to stop you. Copying the answer into your submission is one keystroke, and nothing in the design of a general chat pushes back.
How does CANtutor AI handle each of those?
Each assignment gets its own workspace holding the instructions, attachments and rubric, with a chat scoped to that assignment so you never paste the question in first. The AI Grader marks a draft against the real rubric and returns the specific things costing marks, and Revise with AI shows the changes as a diff you accept or reject line by line.
In a live session your camera, your shared screen and any file you upload feed the same conversation, and the tutor writes the steps and sketches graphs on a shared whiteboard while it talks. You can save a board and find it again before the test.
On the last point, the design is mechanical rather than a slogan. The tutor starts in Learn mode, which teaches the method and asks you to do the next step. Practice mode asks for your attempt before it says anything. Answer mode exists and is labelled, and every surface that shows it carries the same warning: Answer mode writes the work for you, and turning in AI-written work as your own may breach your school's academic-integrity policy. The grader ignores the mode, so the switch cannot soften a mark.
When is ChatGPT the right tool anyway?
When the question is general. What is a derivative, how does a citation work, why did the Treaty of Versailles matter: a general assistant answers those well, and a tutor session would be more than the moment needs. It is also the right tool when you want breadth across a dozen subjects in an evening rather than depth on one problem set.
The honest rule is this: if the work is not graded and the question is general, ChatGPT is fine. If the work is graded and specific to your course, use something that has read the course. Credits meter a CANtutor session, and the plans are on /plans, so it makes sense to spend them on the problem that will not budge rather than on definitions a search would answer.
What about Google Classroom?
A chat window does not know what is due. CANtutor AI can. Google Classroom connects for personal Google accounts and for school accounts where the district permits third-party apps. Some districts block it; if yours does, everything else still works and you upload your material instead. Once connected it is a read-only, one-way sync: nothing is submitted or written back to your teacher, and the assignments, due dates, attachments and rubrics arrive on their own.
Questions people ask about this
Is using ChatGPT for homework cheating?
That depends on your school's policy and on what you do with the output. Asking for an explanation is usually fine; submitting generated text as your own usually is not. The safest habit is the one CANtutor AI's Practice mode enforces: attempt it first, then ask for the smallest hint.
Can ChatGPT see my screen?
Check ChatGPT's own feature pages for what its apps can take as input; we only restate what is on the vendor's site. A CANtutor AI live session takes your camera, your shared screen and uploaded files, and draws the working on a shared whiteboard.
Does CANtutor AI use ChatGPT underneath?
The privacy policy names OpenAI as the AI that answers questions, grades work and builds lessons, and Google as the AI that runs a live voice session. The product is the layer around them: the session, the whiteboard, the rubric, the modes and the grader.
