Visual tutor
Some ideas are easier to see.
Turn a question or your notes into a narrated visual explanation. Pause a drawing, ask about part of it, revisit a section, and try the lesson’s checkpoint.
Want a different voice for the explanation? Gossip style turns the topic into a lively study analogy while keeping the lesson grounded in your material.
Study Simulator
Read it once. Work with it in more ways.
A guide to find the shape of a topic. Flashcards to retrieve the details. A quiz to see what needs another pass. A podcast when you want to listen.
Flashcards
Practice retrieving one idea at a time.

How Study Simulator works
Writing & research
A clearer draft. A better look at your sources.
Revise a passage, check grammar, plan an essay, find a citation, or look up scholarly sources. Check for AI writing and plagiarism, with clear notes on what each check can and can't tell you.
Detector scores and web matches are signals to review, not proof of authorship or copying.
Exam prep
Find what you know. Then find your next question.
Try original sample questions for the available entrance, healthcare, and AP tests, with answer explanations. Make a separate quiz from your own material when you want focused practice.
Free original questions for SAT, ACT, AP, nursing and medical school preparation, with worked explanations for every answer.
One task? There’s a tool for that.
Study, writing, source research, word counting, and everyday calculations. Go straight to the task you need.
A few things to know.
A quick tool when you need it. An account when you want to keep it. Pro for your course workflow.
Can I try StudySim without signing up?
Yes. You can try the AI tools free without signing up. The word counter and calculators are always free. Sign in when you want to save your work.
What is Study Simulator?
StudySim is an AI study workspace from XYZAI, Inc. that turns your own notes, PDFs, slides and recordings into study guides, flashcards, quizzes and study podcasts. It is the home for your study tools and saved courses. Use a quick tool on its own, or open a course to return to its sources, study guides, flashcards, quizzes, podcasts, and saved visual lessons.
What does StudySim Pro add?
Pro turns everything saved in a course into study guides, flashcards, quizzes and podcasts. See Pricing for plans.
Will my existing courses still be there?
Yes. All your courses and saved work are still here. Open Study Simulator to find them, or select "Where are my tools?" in the sidebar for a quick tour.
Can I trust every AI answer or detector score?
Review AI explanations against your sources, especially before an exam or submission. Writing detectors can be wrong, and a web similarity scan cannot establish copying or misconduct. Each tool explains the scope of its output.
How much does StudySim cost?
The free tools cost nothing and have usage limits. Pro is $1 for your first 3 days, then $20/month or $120/year unless you cancel. Cancel from your account at any time.
Start with what you’re working on.
A problem, a paragraph, a page of notes. Bring it to StudySim and choose your next step.
