Study

Study lives in the same app.

Tap Study at the top of the screen. Four tabs hold your day, your courses, your cards and your notes.

Or tap the tabs inside the phone. It is a sample, so nothing you do there is saved.

A phone on chud's Study screen, the greeting Good morning, a Next up card to review 3 cards, and Tuesday's classes with the Unit 3 test on Friday.

The real Study Today parts, with sample data. The page layout is an illustration.

Why students keep it open

Four reasons it beats a search bar at 11pm.

It teaches. In Study, it checks.

Pick Understand and you get the steps your class went too fast through. In a Study chat, a question comes back to make sure each step landed before the next one arrives.

Your course, unit by unit.

12 courses written out unit by unit (10 of them AP exams), 471 topics in all. Open your course and every unit is there by name.

Your notes become the quiz.

Write your notes in Study, then turn any note into a flashcard deck or a quiz in one tap.

And it does the rest of your week.

The same Pip that drills your units writes the email, plans the trip, argues with your thesis and debugs the code. School is one lane, not the whole road.

The course count is read off the shipped curriculum every time this page loads. Try one right now. Ask up to 4 questions free, no account. chud keeps your guest chat only in this browser.

Start from where you are

Pick the night you're having.

These are real prompts, shown in full. Tap one and it opens in Pip, ready to send. If it needs your work, add it first.

Step by step

Explained one step at a time.

Pick Understand and Pip breaks a concept into the steps your class went too fast through. In a Study chat, it checks each one before moving on. Ask it about an essay and it shows you the reasoning behind it, so the next one is yours.

How the study side works

Exam practice

Practice that follows your course.

12 courses are written out unit by unit: SAT and ACT, plus 10 AP exams. Open one and every unit is there by name, each with a lesson written ahead of time. Here is every course, and how finished it is.

471 topics across 12 courses, with lessons written one at a time.

SAT28 topics
ACT28 topics
AP Biology30 topics
AP US History41 topics
AP Calculus AB29 topics
AP World History95 topics
AP Physics C: Mechanics34 topics
AP Chemistry92 topics
AP Human Geography28 topics
AP Physics 129 topics
AP Physics 222 topics
AP Physics C: E&M15 topics

These are counted from the shipped courses when this page loads, not typed into the copy, so they cannot quietly drift away from the product. A course still being written stays on this list at whatever it really is, rather than waiting until it looks good. That is the only reason to believe the rows that read 100%.

Feedback

Wrong answers are the useful part.

Get one wrong and Pip shows the right answer and a short reason, while the thought is still warm. Paste your own work and it marks what's weak.

More on how it teaches

After the exam

It's still there when the exam's over.

The same Pip that drills your units writes, plans and argues back. Résumés, scholarship-essay coaching, interview practice, the group project nobody else started. School is one lane, not the whole road.

What Pip is like to talk to

Before you go

The questions everyone asks first.

Short answers, no fine print, and every one of them links to the page that proves it.

Help that teaches, with no ads on any plan.

Every plan starts with the same promise: explain it, and check it landed when you ask.
