Many students now ask ChatGPT for a quiz. It works, and it can be a good study partner. So why use a separate app? The short answer: ChatGPT is great at talking, and Quizfix is built to keep track. This page shows where each one fits.
What ChatGPT does well for study
ChatGPT has a study mode. OpenAI launched it in July 2025, and it is on all ChatGPT plans on the web, iPhone and Android. Instead of just giving the answer, it asks you questions and gives hints. It checks what you know as you go.
When you ask, ChatGPT can quiz you, make practice questions, explain what you missed, and make flashcard style review. Some accounts also show a Quizzes shortcut. You can upload a PDF, Word file or slides and ask for questions on it. The best part is follow up. If an answer confuses you, you can ask why, and ask again in simpler words.
There are limits. OpenAI says study mode can make mistakes, so check important facts. The study option is not in Projects or custom GPTs. Your quiz lives inside one chat, so you need to come back to that thread and ask again to review. Spacing reviews over days is up to you.
What Quizfix adds
Quizfix is not a chat. It is a study app with one loop. You add your slides, a PDF, a Word file, photos of notes, a YouTube lecture or a web article. Quizfix makes a test with multiple choice, true or false and fill in the blank questions. Every question comes from your material, and each answer says why.
After the test, your score and the exact questions you missed are saved. The Fix round turns misses into cards and drills them. Cards come back with spaced repetition when they are due. Set your exam date, and each day Today's session gives you due cards plus a few questions on weak topics. Readiness shows how much you know now, from your real answers.
Why tracking matters
A quiz helps most when you come back to it. Ebbinghaus (1885) showed that we forget fast without review. Cepeda et al. (2006) found that spacing study over days helps memory more than one long session. Butler and Roediger (2008) found that feedback after a multiple choice test helps you keep the right answer. So the value is not one quiz. It is the next five reviews, on the right questions, on the right days.
ChatGPT can do any single step. Quizfix does the steps in order, every day, without you having to remember. Our guide on spaced repetition before an exam explains the plan in detail.
A good way to use both
- Make a test from your material with the quiz generator or PDF to quiz.
- Look at the questions you missed.
- If a miss makes no sense, ask ChatGPT to explain that idea in a new way.
- Run the Fix round in Quizfix, then let Today's session bring the cards back.
- In the last days, take a Mock exam with a timer. See how to study for an exam in a week.
