## What is Retain Cards?

Retain is a flashcard app designed to help you master large volumes of content quickly. Built by a medical student for high-intensity programs, Retain combines an advanced spaced repetition algorithm with an intuitive, vibrant interface to accelerate your learning without draining your energy.

Whether you are importing existing decks or creating new ones from your class materials, Retain streamlines your workflow so you can spend less time formatting and more time learning.

Key Features:

Modern, Fatigue-Free Design: Replace outdated, visually exhausting interfaces. Customize colors for each deck, giving every subject a unique visual identity that reduces cognitive fatigue.

Anki Import Utility: Easily bring your Anki flashcards to Retain. Our utility analyzes your deck and lets you import specific content by tags.

Clean Cloze Deletions: Ditch the confusing bracket syntax. Highlight and hide text with a simple button or keyboard shortcut.

Side-by-Side Notes & Quick Clipping: Upload PDFs directly into the editor to view notes alongside your cards. Spot a vital diagram? Drag to clip sections of your notes and instantly paste them into your flashcards.

AI-Powered Study Partner: Leverage AI for study tools legacy apps can't match. Go hands-free with voice study mode while the AI quizzes you aloud. Type a focus using natural language to curate an instant session, and get automatic AI card suggestions from your clipped notes.

Seamless Cloud Syncing: Switch effortlessly from your laptop to your phone. Retain logs your reviews instantly in the cloud.
