Turn your class handouts into a study app for the test
For French, Spanish and Latin, courses 1 to 4. Snap the worksheets your teacher gave you; Cahier makes practice from exactly that.
Free: one unit from up to 6 pages. No card needed.
What you actually get
Real screens from the demo unit, not mock-ups.
Your unit: every activity built from your handouts 
The skill map: what you know and what's shaky 
Practice: graded on the spot, with the why
Three steps to test day
Snap your handouts
Worksheets, vocab lists, readings, song lyrics. Up to 8 photos or PDFs per unit.
Check the skill map
See the skills Cahier found and untick anything that isn't on your test.
Study until the test
Short reviews spaced toward your test date, a mock test, and drills on what you keep missing.
Not another generic flashcard app
Built from your handouts
Your teacher's vocab, your teacher's grammar point, your teacher's reading. Not a textbook someone else picked.
More than flashcards
Conjugation grids, error hunts, sentence builders, dictation, reading checks, sorting, and for Latin, case finding and scansion.
Spaced to your test date
Tell Cahier when the test is. Reviews get closer together as it gets near, then a mock test.
Your mistakes, drilled
Cahier tracks the kind of mistake you make (wrong ending, wrong gender, wrong tense) and gives you more of exactly that.
The AI reads your handouts and writes the questions. Our code grades every answer and picks what you see next. It never writes your French for you.
For parents
What you'd want to check before your kid uses it.
Answer keys are checked
Every question's answer is checked before a student sees it. Anything that fails the check is thrown out.
No ads, no data sales
No ads, no tracking cookies, and nobody trains AI on your child's work.
Teachers see scores, not typing
If your child joins a class, the teacher sees scores and kinds of mistakes, never what they typed.
13 and up
Cahier asks for a birth month and year first. Under-13s can't sign up.
Payments by Lemon Squeezy
Lemon Squeezy takes the payment and sends the receipts. Students under 18 send a link to a parent to pay.
Delete any time
Account → Delete my account removes everything right away. Uploaded handouts are deleted 30 days after a unit is built.
For teachers
Build a unit once from your own handouts and give it to the whole class.
Classes with a join code
Students join with an 8-character code or link. You see scores and the kinds of mistakes your class makes.
You review first
Look over every activity before you publish it to the class, and swap or edit anything you don't like.
Approval required
Every teacher account is checked by hand before it can make classes.

Questions
Which classes does it work for?
French, Spanish and Latin, courses 1 to 4 (French 1 through French 4, and the same for Spanish and Latin). Pick your language and course when you start.
What can I upload?
Photos or PDFs of anything your teacher handed out: worksheets, vocab lists, readings, notes, song lyrics. Up to 8 files per unit. Crop out other people's names and faces when you can.
Is the AI going to get the answers wrong?
Every answer key is checked before you see it, and questions that fail the check are dropped. If something still looks off, tap Report on the question.
Does it do my homework for me?
No. Cahier makes practice questions from your handouts and grades your answers. It doesn't write sentences or essays for you.
What does free include?
One unit, from up to 6 pages of handouts, with every activity type. No card needed.
I'm under 18. How do I pay?
Send a link to a parent from the Billing page. They choose a plan and pay; your account updates on its own.
Can I cancel?
Yes, any time: Manage billing on the Billing page (or a parent's link), or the link in the Lemon Squeezy receipt email. The plan stays on to the end of the period already paid, then stops renewing. Your units stay.
Can I get a refund?
Yes. Email us within 14 days of a charge and we'll refund it in full. A parent who didn't approve a purchase their child made gets a full refund any time. Details are in the Terms.
Can my teacher see my answers?
Only if you join their class, and then only your scores and the kinds of mistakes you make, never what you typed. Not your other units or your handouts.
How do I delete my account?
Account → Delete my account. It goes right away. You can download all your data first.
