Free AI Tutor for Students: Get Homework Help in Any Subject

Stuck on homework at 10pm? Can't afford a $50/hour tutor? You're not alone. Millions of students struggle with homework every night, and not everyone has access to help when they need it most.

That's where AI tutoring comes in. GradingPen's AI Tutor provides instant, step-by-step help in any subject — from algebra to AP History — for a fraction of the cost of traditional tutoring.

What Is an AI Tutor?

An AI tutor is a software tool powered by artificial intelligence that can explain concepts, solve problems step-by-step, and provide personalized help — just like a human tutor, but available 24/7 and at a fraction of the cost.

Unlike simply Googling the answer, a good AI tutor teaches you the method. It doesn't just give you the answer to "solve 3x + 7 = 22" — it walks you through each step so you understand the process and can solve similar problems on your own.

What Subjects Does It Cover?

GradingPen's AI Tutor handles 70+ subjects, including:

• Math: Algebra, geometry, trigonometry, calculus, statistics
• Science: Biology, chemistry, physics, earth science
• English: Essay writing, grammar, literature analysis, reading comprehension
• History: US History, World History, government, economics
• Foreign Languages: Spanish, French, German, and more
• AP Courses: AP Calculus, AP Biology, AP English, and all major AP subjects
• Test Prep: SAT, ACT, GRE practice questions

How It Works

Using the AI tutor is simple:

1. Type or upload your question. You can type it out, paste a problem, or even snap a photo of your textbook and upload the image.
2. The AI reads and understands your question. It identifies the subject, the type of problem, and what you need help with.
3. Get a step-by-step explanation. Not just the answer — the full method, so you learn how to solve it yourself.
4. Ask follow-up questions. Didn't understand step 3? Ask the AI to explain it differently.

Upload a Photo of Your Homework

One of the most powerful features is photo upload. Take a picture of your homework problem — whether it's a math equation on a whiteboard, a printed worksheet, or handwritten notes — and the AI reads it using OCR (optical character recognition) and provides help.

This is especially useful for math and science where typing complex equations is difficult.

Is AI Tutoring Cheating?

This is the #1 question parents and students ask. The short answer: no — when used correctly.

GradingPen's AI Tutor is designed to teach, not to do your homework for you. It explains the method and walks you through the reasoning. It's no different from asking a human tutor for help — the learning still happens in your brain.

That said, we recommend:

• Try the problem yourself first before asking for help
• Read the explanation and try similar problems on your own
• Use it as a study tool, not a shortcut

AI Tutor vs. Human Tutor: Cost Comparison

Let's be real about the numbers:

• Human tutor: $40-80/hour, typically 1-2 sessions per week = $320-640/month
• GradingPen AI Tutor: $9.99/month for unlimited help, 24/7, any subject

That's not a typo. For less than the cost of a single tutoring session, you get a full month of unlimited AI tutoring in every subject.

AI tutoring doesn't replace human tutors for everything — complex social-emotional learning and test anxiety coaching are better with humans. But for homework help, concept explanation, and practice problems? AI is faster, cheaper, and always available.
