Questions and answers
How to upload a test from Word, Excel or PDF, how to mark correct answers, where your data is stored and how mistake practice works.
Is it free?
Your first 3 test uploads are free. After that, uploading new tests requires a subscription, while tests you’ve already uploaded can be taken for free as many times as you like.
Which file formats are supported?
Word (DOCX), PDF with a text layer, Excel (XLSX, XLS, ODS), CSV and plain text (TXT). Files in the old .doc format need to be re-saved as .docx.
How do I mark the correct answer in my file?
Any way you’re used to: bold, color or underline in Word, an asterisk or plus before the option (*B), an answer key at the end of the file (“Answers: 1-B, 2-C”) or a “Correct answer” column in Excel. If the answers aren’t marked but the correct one is always in the same position (for example, the first option), choose that when uploading or describe it in your own words — AI will take your hint into account.
Is my file sent to a server?
The file itself is not: it’s read in your browser. Only the extracted text is sent to the server, where it’s recognized by AI (Google Gemini). Your tests and history are stored in your account on a server in Kazakhstan.
What if the questions were recognized incorrectly?
After uploading, a review screen opens where you can mark the correct answers, fix the text, delete extra questions and rename the test. The test is saved only after you confirm.
Can a question have several correct answers?
Yes. During the test, these questions are shown with checkboxes and a “Check” button. An answer counts as correct when all the correct options are selected and nothing extra is.
How does mistake practice work?
It includes the questions you got wrong. If you make a mistake again, the question comes back 3–5 questions later in the same session. A question counts as learned after two correct answers in a row in mistake practice, and then it leaves the queue. The order of questions is based on the Leitner system.
Will my progress be saved if I close the page?
Yes. Every answer is saved immediately, so you can continue an unfinished attempt after reloading the page or the next day.
How do I move my tests to another phone or computer?
On the “History” page, download a backup in JSON format and restore it on the other device. It also includes your results and per-question statistics.
Can I study on my phone?
Yes, the interface is designed primarily for phones: large option buttons, a dark theme and picking up an attempt right where you left off. On a computer, keyboard shortcuts work too: 1–9 or A–D to choose and Enter to move on.
