Ebbinghaus is a simple, focused flashcard app built around the science of spaced repetition – so you remember more in less time, without clutter or distractions. Create your own decks for any topic (languages, exams, work, hobbies) and let the app handle the review schedule for you, based on Ebbinghaus' classic forgetting curve. +++ WHY EBBINGHAUS? +++ + Minimal, distraction-free design: Just your cards. No feeds, gimmicks or noisy UI – ideal for deep focus. + Spaced repetition built-in: Cards are automatically scheduled using increasing intervals so you review right before you’re likely to forget. + Free review mode: Want an extra run-through before a test? Flip through any deck (shuffled) freely without affecting your spaced-repetition schedule. + Progress you can see: A simple chart shows your recall ability over time at different intervals (1, 2, 4, 8, 16, 32 days), plus lifetime correct vs incorrect cards. + Smart reminders: Optional daily notifications per deck so you never miss a review session. + Dark mode: Easy on the eyes for late-night study sessions, with a thoughtful dark theme throughout the app. + Private by design: Your cards live on your device. No account required. Whether you’re learning a language, preparing for an exam, or just want a better memory, Ebbinghaus gives you a calm, science-backed way to make what you learn actually stick.

Have you ever dreamed about learning from what you actually like to read? Some words that appear again and again while you are reading in a foreign language, any website, any article, or piece of news. You don’t know or don’t remember how to translate them, and sometimes translators mislead with infinite dictionaries of possible translations. CluedUp.ai will help you not only reduce the time spent translating and tracking relevant, contextual information, but also conveniently save the words and practice along with relevant vocabulary in a learning-friendly environment. So how does it work? No destruction while reading. You just select a single word, click the badge and see the translation of the selected text inside the surrounding context, click the save button, and that’s it. What’s next? The saved word appears in the learning dashboard. We track each 10th of your savings and build a custom learning pipeline based on your selection word complexity and semantic relevance. In simple words, if you save the words related to “sleeping” at around the B1 level, we will provide you with vocabulary lessons related to sleeping at the current level. You can choose the vocabulary complexity you want to practice, and we will do our best to fit the vocabulary pool to your needs. What languages do we support? While our primary focus is on expanding the language support, we currently offer features for the Estonian community that want to progress in English. Am I safe using the extension? Yes! We want to emphasise that we want to teach you new vocabulary usage, not track your personal data. CluedUp.ai has no interest in tracking any personal data. Moreover, you are completely safe to translate any text. We don’t save your translation history until you explicitly save the relevant word. Any extra concerns? We get it. You can always click the pause button and prevent the extension from working in your private pages. If you have any issues or concerns, please contact support@cluedup.ai to get instant assistance. Every user’s voice is important to us, and we will do our best to provide you with the best possible experience. Learn more about our privacy policy here https://app.cluedup.ai/privacy_policy
