Study Made Simple, Smart, and Sustainable

constant. is an AI-powered learning app designed to turn your notes, textbooks, lecture slides, and readings into effective study material—without the manual effort. Upload a photo, PDF, or document, and constant. automatically generates high-quality multiple-choice questions that test your understanding of the content. These questions are organized into decks, ready for you to review anytime.

Built on the principles of spaced repetition, constant. ensures that what you learn actually sticks. It schedules reviews at the right time to strengthen memory and recall. But unlike traditional flashcard apps, you don't need to spend hours writing your own cards—the AI does the heavy lifting for you.

When you're studying, constant. goes beyond simple question-answering. If a question is unclear or sparks curiosity, you can dive deeper with an integrated chat AI that understands the context of the exact question you're working on. This makes studying more interactive, personalized, and engaging.

With constant., you spend less time preparing and more time mastering what matters. It's study made simple, smart, and sustainable.
