Honestly? Sometimes you should just use ChatGPT.

It's free, it's already on your phone, and it's a better model than anything we could build. We're not going to pretend otherwise. Here's the four things it can't do.

01

You have to explain your class. Every time.

ChatGPT has never heard of Honors Chemistry at Harvard-Westlake. So you write a paragraph describing it — and then you write it again on Thursday. We read your school's 2026–27 catalog back in September. You tap your course once.

02

The chat scrolls away. The deck doesn't.

Try finding the cards you made on Monday. Your deck is still sitting under your course, units in order, where you left it.

03

It's one link for all 22 of you.

Nobody has ever dropped a ChatGPT conversation in a group chat and said "use this." Send a Scratchpaper deck and it opens for everyone in your section — no app, no account.

04

You can say it out loud.

We show every step, hand you a video on the concept, then give you one more problem to do yourself. We don't hand over the answer. That's a sentence you can say to your teacher.

It teaches. It won't do it for you.

Not a policy page — this is what actually happens when you ask it to just give you the answer.

REAL EXCHANGE · ALGEBRA 1 · UNIT 4
Student just tell me the answer to #7, i'm out of time
Scratchpaper Not going to hand it over — but we'll get you there fast. #7 gives you 2x + 7 = 19. Before anything else: what has to happen to the 7 so that the x-term is alone on the left? Tell me that one move and I'll walk the rest with you.

What you actually get.

01

Flashcards, a quiz, or a summary

Built from your course's real units — or paste your own notes and we'll build from those instead.

02

Homework, worked all the way through

Photograph the problem or type it. Every step shown, a video on the concept underneath it, and one more problem so you can prove you've got it.

03

A tutor that asks before it tells

Explains at your grade level and coaches you to the answer instead of reciting one.

04

A study plan that fits your actual week

Tell it the test date and how much time you really have.

What's not done yet.

We'd rather you hear it from us than find out at 11pm.

Unit breakdowns are richest on core courses

The 79 Common Core / NGSS / AP-framework courses have full unit maps. The 2,578 school-catalog courses have department, level, and grade band — unit detail is being filled in school by school.

!

Photos work — handwriting is hit and miss

Point your camera at the worksheet and we'll read it, and we'll show you what we read so you can catch a misread. Clear print is reliable; messy handwriting and dark photos still trip it up.

It can be wrong

It's an AI. Check it against your teacher's material, and tell us when it misses — there's a thumbs-down on every screen and we read all of it.
