I Tried 5 Free AI Homework Helpers — Here's Which One Actually Saved Me Time

I tested ChatGPT, Wolfram Alpha, Photomath, and others for homework help. Here's what worked, what didn't, and which one I actually use.

I've been using AI tools to help with homework for the past semester. I tested five different free options to see which ones actually save time and which ones are just distracting. Here's what I found.

1. ChatGPT (Free Version)

ChatGPT can help with almost any subject — math, writing, science, history. I used it for explaining concepts and reviewing essays.

What worked: Explaining why I got a math problem wrong. I'd paste the problem and my answer, and ChatGPT would explain the mistake clearly.

What didn't work: It sometimes gives confident-sounding but incorrect answers, especially for math. I had to verify everything.

Time saved: 10–15 minutes per homework session, but only if I verify the answers.

2. Wolfram Alpha (Free Version)

Wolfram Alpha is specifically for math and science. You type in a problem and it shows you the answer and the steps.

What worked: Checking my math answers. If I got a different answer than Wolfram Alpha, I'd find my mistake.

What didn't work: It doesn't explain the reasoning — it just shows steps. Sometimes the steps are hard to follow.

3. Photomath (Free Version)

You take a photo of a math problem and Photomath solves it with steps.

What worked: Quickly checking if my answer is right. The step-by-step solutions are usually clear.

What didn't work: The free version has limited steps shown. For harder problems, you need the paid version.

4. Khan Academy (Free)

Khan Academy isn't an AI homework helper, but it's my go-to for understanding concepts I'm stuck on.

What worked: Finding a video explanation of a concept I didn't understand. Usually there's a video that explains it better than my textbook.

What didn't work: Takes time to find the right video. Not instant help.

5. Quizlet (Free Version)

Quizlet is for making and studying flashcards. I use it to make flashcards from my notes, then study them.

What worked: Studying for tests. The spaced repetition algorithm is genuinely helpful.

What didn't work: Making the flashcards takes time upfront. You have to be disciplined about using it.

My Honest Assessment

Free AI homework helpers are useful for checking answers and understanding concepts you're stuck on. They're not useful for actually learning the material — you still have to do the thinking.

How to Use AI Homework Helpers Without Cheating Yourself

The biggest risk with AI homework helpers isn't academic dishonesty — it's using them in a way that prevents you from actually learning. Here's how to use them productively:

Use them after you've tried: Attempt the problem yourself first. Use AI to check your work or understand where you went wrong, not to get the answer before you've tried.

Ask for explanations, not answers: Instead of "what's the answer to this problem?", ask "can you explain the concept behind this type of problem?" or "I got X as my answer, but the correct answer is Y — where did I go wrong?"

Verify everything: AI tools, including ChatGPT, make mistakes. Always verify important answers against your textbook or another source.

Use them for understanding, not completion: The goal is to understand the material, not to complete the homework. If you're using AI to complete homework without understanding it, you're setting yourself up for failure on exams.

AI Tool Comparison Table

Tool	Best For	Free Tier	Accuracy
ChatGPT	Explanations, writing feedback	Yes (limited)	Good but verify
Wolfram Alpha	Math, science calculations	Yes (limited)	Very high
Photomath	Math step-by-step	Yes (basic)	High
Khan Academy	Concept learning	Yes (full)	High
Quizlet	Memorization	Yes (limited)	N/A

The Academic Integrity Question

Using AI to understand concepts and check your work is generally acceptable. Using AI to complete assignments you submit as your own work is generally not acceptable and may violate your school's academic integrity policy.

The line isn't always clear. When in doubt, ask your teacher: "Is it okay to use [tool] for this assignment?" Most teachers appreciate the honesty and will give you a clear answer.

Frequently Asked Questions

Q: Is using ChatGPT for homework cheating?

It depends on how you use it and your school's policy. Using it to understand a concept is generally fine. Using it to write an essay you submit as your own work is generally not fine. Check your school's academic integrity policy and ask your teacher if you're unsure.

Q: Is Wolfram Alpha accurate for all math?

For standard math (algebra, calculus, statistics), Wolfram Alpha is very accurate. For unusual problem formats or highly specialized topics, verify the answer. The step-by-step solutions are generally reliable.

Q: Can AI tools help with essay writing?

AI tools can help you brainstorm, outline, identify weak arguments, and check grammar. Using AI to write the essay for you is academic dishonesty. The line is between using AI as a tool to improve your writing vs. having AI do the writing.

Q: What's the best free AI tool for math homework?

Wolfram Alpha for calculations and checking answers. ChatGPT for understanding concepts and working through problems step-by-step. Photomath for quickly checking arithmetic and algebra.
