Know what you actually know, before the exam does
alcoia asks you a question about what you just read, in your own words, right when a passage looks like it slipped past. Answer it and keep going. Miss it and you find out now, while you can still do something about it, instead of in the exam.
Reading it is not the same as knowing it
A page can feel understood because it was easy to get through, and a highlighter hides that difference by making everything look handled. alcoia checks quietly while the reading is fresh, so the gap between feeling ready and being ready shows up early.
How it feels to use
It stays out of the way while you are reading well. When you slow down or start re-reading, it asks one short question about the sentence you just read. Get it right and it says nothing. Get it wrong and it explains, once, then leaves you to keep going.
Why a question and not a summary
Pasting a page into a chatbot gives you three tidy paragraphs and the feeling that you understood it. You read none of it, and it is gone in days. Being made to recall something is what moves it into memory you can use later. alcoia asks; it does not summarise.
What your professor can see
If your course uses alcoia, your instructor sees the class as a group and never you on your own. What you read outside the assigned material is never collected, and nothing about your reading is shared with your instructor or with us beyond the anonymous group view.
