Cerego is an online tool designed to help you learn more effectively and remember more of your chosen subjects. Based on principles from neuroscience and cognitive science, Cerego adapts to your progress and calculates what content you need to review—and when.
Currently there are about 50 courses you can start learning on Cerego, covering topics such as art history, statistics, the periodic table, and computer shortcuts. The courses are like interactive flashcards, and users can add their own content (useful if you're studying for a test or are taking an online learning course).
The highlight of Cerego is its learning algorithms, which the developers say optimizes learning for each individual. Every time you use the system, it assigns a "memory strength" for each of your answers (based on factors like your cumulative performance and last time you saw that item). Then it creates a new lesson with the items you need to review most so you can best retain that knowledge over the long term.
You can learn more about the fascinating science of it in the video above. The app is in invite-only beta right now, but the first 2,000 Lifehacker readers can sign up right now via the link below.
Update: If you haven't received your invite yet, please be patient. We've "Lifehackered" the Cerego servers.
