Extension Metadata

About this extension
Kreen turns the practice questions you work through into study material you'll actually review.

Capture a question while you study, and Kreen's side panel builds:

• Smart notes: a concise, grounded explanation of the concept behind the question, with the key takeaway pulled out.
• Anki cards: cloze and basic cards generated from your notes, ready to export.
• Figures: the images and tables from the question are kept with your notes.

Export your way:
• Anki package (.apkg)
• Straight into Anki through AnkiConnect
• Printable study document (.doc)

Built for USMLE students who want to go from "I missed this" to "I'll remember this" without retyping anything.

How it works
Kreen runs in Firefox's side panel. Sign in with your Kreen account, capture a question from the page you're studying, and the note and cards appear in the panel. A free plan is included, with higher daily limits on paid plans.

Privacy
Kreen only reads the question page when you choose to capture it. Your notes are stored in your Kreen account. Details: https://kreen.uz/privacy.html
