Frequently Asked Questions

  • What is Memgrain?

Memgrain is an AI-powered study tool. It streamlines and elevates your learning experience by quickly converting various materials like notes, lecture slides, web articles and more into flashcards. Our platform allows you to organize these cards into subjects and study decks, grouping related information for efficient learning. You can then use AI to edit, chat with and test your mastery of your flashcards. Our tailored spaced repetition algorithm optimizes your study sessions, ensuring maximum retention of information by reminding you to review material right before you're likely to forget it. Engage with Memgrain for a smarter and more effective way to commit knowledge to long-term memory.

  • What type of content can be converted to flashcards?

Memgrain offers robust support for a wide array of file types to enrich your learning experience. You can upload PDFs, various image formats (JPEG, PNG, etc.), handwritten notes in digital format, PowerPoint presentations, Word documents, links to informative websites, and many other resources. Our platform is designed to accommodate diverse learning materials, enabling you to compile and memorize content that spans text, visuals, and audio. This versatility ensures that no matter what form your information takes, Memgrain is equipped to help you commit it to memory effectively.

  • What is spaced repetition?

Spaced repetition is a learning technique that involves reviewing information at increasing intervals to improve long-term retention of knowledge. It's based on the psychological observation that we remember things better if we learn them several times, spaced out over a long period, rather than cramming in a short time frame. This method is especially effective for memorization, as it gradually spaces out the review sessions before the memory fades, reinforcing the learning each time.

  • Is Memgrain only for students?

No, these tools are beneficial for anyone interested in learning and retaining information, not just students. Lifelong learners, professionals, and hobbyists can all utilize flashcards and memorization techniques to enhance their knowledge base. Whether it's mastering a new language, remembering important historical dates, or keeping up with professional certifications, spaced repetition with flashcards can significantly boost memory retention. By engaging with this active recall practice, learners of all ages ensure that information is not only learned but also retained over the long term, making it a valuable habit for continuous personal and professional growth.

  • How do you keep prices so low?

Our unique approach and small dedicated team allow us to maintain the lowest prices amongst our competitors.

  • Can I buy extra credits as a Monthly Plan member?

Yes, you can buy as many as you need beyond the 1,500 credits you get each month. If you do buy more credits, they will roll over to future periods. We will always use your monthly 1,500 credits first before using up any of your purchased credits.

  • What tools beyond the memorization tool will you be adding?

We are constantly working to find the best ways to integrate AI with learning. We will continue to develop new tools that will enhance your lifelong learning experience.

  • Is there a limit to the number of credits I can use each month?

No, but we do impose a daily limit to maintain fairness and safe use of our tools, but this limit should never be reached with normal use.

  • What languages does Memgrain support?

While our site is displayed only in English at this time, flashcards can be generated or translated into most languages.
