Kreen lives in Chrome's side panel. After each question, it drafts a grounded note and active-recall cards, then files them into study sessions you export to Anki or Word.
A 67-year-old woman with Hashimoto thyroiditis comes to the clinic because of fatigue and tingling in both feet. Hemoglobin is 9.1 g/dL and MCV is 112 fL. Vibration sense is decreased in both lower extremities. Which of the following is the most likely underlying cause of her findings?
Missed one?Capture the question you're on and Kreen turns it into a note and cards.
Interactive preview — click through it. Example content; every note is a draft to check against your sources.
Doing questions is only half the work. Kreen makes the other half — reviewing what you missed — fast enough to happen every time.
Every note comes with cards that make you produce the answer, whether open recall, exam-style vignettes, or cloze, because testing yourself beats rereading.
Cards go straight into Anki, so the concepts you missed come back on a spaced-repetition schedule instead of disappearing after the block.
Notes are drawn from the question in front of you, not invented facts, and presented as a draft you verify and edit before you trust it.
No copy-paste, no tab-switching. Kreen works right beside the question.
On a supported question bank, click Capture question. Kreen reads the page only when you ask it to.
A concise, high-yield note and cards in the style you choose, each with a short explanation of why.
After the block, send cards to Anki and notes to a formatted Word document in one click.
A focused tool that stays out of the way until you need it.
Stuck mid-question? A progressive hint nudges your reasoning without revealing the answer.
Open recall, exam-style vignette, or cloze deletion, chosen per card.
One-click Anki decks named after your session, and printable notes with a recall-cue margin.
Pin an ECG, image, or table from the question so it stays attached to the note.
Notes are tagged by subject, system, and topic, and grouped by study session.
Turn a session's notes into a short spoken review for the commute or the gym.
Medical content deserves care. Kreen is designed to support your judgment, not replace it, and to touch as little of your data as possible.
As a medical graduate, I built Kreen around a simple observation from question-bank study: the questions you miss are the most valuable ones, but reviewing them properly takes time most students don't have mid-block.
Kreen closes that gap with careful, verifiable notes and active-recall cards, designed to support clinical reasoning rather than shortcut it. Feedback is always welcome — get in touch.
Free to install. Works alongside the question bank you already use.
