Flashcards and a cheat sheet

How it works
- 1
Tell us about your exam
Fill in the form and share a Google Drive folder with everything for the course. Your site can only cover what you send us.
- 2
We build it from your course
We use AI to turn your materials into lessons and questions, then a person checks it for accuracy before it goes out.
- 3
Open your private site
We share it to your Claude account and email you when it's ready. Use it on your laptop or phone.
Rather do it yourself?
Grab the free prompt
It’s the prompt I used to build my sister’s first study site. Paste it into Claude with your course materials and it’ll get you most of the way there.
Just know AI still needs some finessing and love: checking every answer, filling the gaps it misses and tuning it to how your prof asks questions. That last stretch is what Lock In does for you.
Questions
How do I get my site?
Your site is shared with you privately through Claude, the AI app. You'll need a Claude account with the same email you put in the form. A free account works, and it only takes a minute to make. Your progress saves as you study.
What should I put in the folder?
Everything for the course. We build your site only from what you send, so if a topic isn't in your folder, it won't be in your site. You need the course outline and what the exam covers, plus your lecture slides or notes. Practice questions and past tests help a lot, if your course gives them out.
How is this different from asking ChatGPT for flashcards?
Generic AI flashcards tend to stay surface level. Your site is built around your course's actual content and question style, with lessons, explanations for every wrong answer, drills and a full mock exam, and a person checks it before you get it. We do use AI to build it, but from your course, not the whole internet.
How long does it take?
Your site arrives within 24 hours of payment. The earlier you request, the more time you'll have to actually use it.
Why are spots limited?
Every site is built and checked by hand, so we only take a few requests each day. Once we're full for the day, the form reopens the next morning. Request early, especially close to finals.
How do I pay?
By Interac e-Transfer ($15, our early bird price for our first students) once you submit the form. The details show up right after you send your request. If we can't build your site, or it isn't ready within 24 hours of payment, you get a full refund.
Is this allowed?
Your site is for your own studying only, and we never share your materials or your site with anyone else. Some schools have rules about sharing course materials, like lecture slides, outside the course, so check your school's policy before you send them. Your own notes are always yours to share. It's also not for assignments, take home tests or anything you're graded on directly.
Can I share my site with friends?
Please don't. Lock In is a tiny operation and each site is made for one person. If your friends want one, send them here instead. We'd really appreciate it!
Can I make one myself?
Yes! There's a free prompt further up this page that gets you most of the way. You'll still want to check the answers and fill any gaps yourself, since AI isn't perfect. Lock In is for when you'd rather have that part done for you.
Who's behind this?
I'm Steph, a product manager in Toronto. I built the first one for my sister's first year exams, and it worked well enough that I'm opening it up. Lock In is a Hundred Blooms Studio project (hundred-blooms.vercel.app). Questions? Email itsfindingsteph@gmail.com.
