How it works

Study, think, reveal. The order matters: the learning happens when you try first.

  1. A practice quiz question with four options

    1. Open your practice quiz

    Any page: a practice test, a PDF, slides, a question set. Nothing to set up.

  2. An answer selected on a practice question

    2. Think it through

    Pick your own answer first. Committing is what makes it stick.

  3. Alt+X revealing the answer with its reasoning

    3. Press Alt+X

    The answer shows in the corner, like 1 : b, with the reasoning in Eco and Max modes.

Use it to learn

Not for graded tests or exams

Using AI to answer graded work is academic dishonesty and can have serious consequences. TrustStudy is for practice quizzes and self-testing. Where the line is.

AI can be wrong

Read the reasoning, not just the letter. If it contradicts your course, trust the course and ask your teacher.

Questions

What does TrustStudy do?

TrustStudy is a Chrome extension for practice quizzes. On any page, PDF or question set, you answer a question yourself, then press Alt+X to reveal the AI’s answer (shown like “1 : b”), with the reasoning when you want it.

Can I use TrustStudy during a graded test or exam?

No. Using AI to answer graded tests or exams is academic dishonesty, and schools treat it seriously. TrustStudy is meant for practice quizzes and self-testing. See how to use AI to study honestly.

How much does it cost?

You get 3 free credits to try it. Then: Basic $5/month (300 credits), Plus $10/month (1,000 credits) or Pro $20/month (2,000 credits). Every plan includes all AI models and input modes, and credits reset each month.

What are Lite, Eco and Max?

Lite answers directly with no reasoning: fastest and cheapest. Eco and Max add reasoning, which is what you want when you’re trying to understand a question.

Are AI answers always right?

No. AI models make mistakes, especially on tricky or ambiguous questions. If an answer contradicts your course material, trust the course and ask your teacher. That’s also why we recommend reading the reasoning, not just the letter.
