Watch Science Based Learning in action
Read AI-generated articles, have voice conversations, drill grammar, and play trivia — all calibrated to your exact level, with every new word saved for spaced-repetition review.
The Scientific Method
Our approach isn't just effective—it's proven. We combine three pillars of cognitive science with AI-generated infinite content so you never run out of fresh material at your level.
Spaced Repetition
The SM-2 algorithm schedules reviews at the exact moment your brain is about to forget, moving knowledge from short-term to long-term memory — automatically.
Active Recall
Every tool forces your brain to retrieve information — translating, speaking, answering. This strengthening of neural pathways is the key to true mastery.
Consistency Tracking
Set daily goals, build streaks, and watch your vocabulary grow. Visual progress feedback turns learning into a habit you actually keep.
Choose Your Learning Path
Start with the tools that match why you are learning, then let the app adapt every lesson to your language and CEFR level.
For working professionals
Practice the vocabulary your work actually needs
Create custom books for your field, read level-matched articles, and save every new term for spaced-repetition review.
For students
Turn classwork into active recall
Use translation feedback, tense drills, and CEFR-calibrated reading to reinforce grammar instead of only recognizing answers on a worksheet.
For conversation builders
Move from study mode to speaking mode
Practice pronunciation, ask questions in Professor Mode, and keep vocabulary moving from short-term recognition into long-term fluency.
7 Powerful Learning Tools
Each tool targets a different skill — reading, speaking, grammar, vocabulary, translation — so every session is fresh and effective.

Getting Started
ScienceBasedLearning is an AI-powered language learning app that combines cognitive science (spaced repetition, active recall) with 7 interactive tools — from voice conversations to grammar drills to AI-generated reading. Available for iPhone and Android with support for 15 languages at CEFR levels A1 through C2.
Getting started takes under a minute. When you first open the app, choose your target language from 15 available options, set your CEFR level (A1–C2), and pick a daily learning goal (5, 10, 15, or 20 minutes). The app immediately calibrates all content to your level. You can change your language or level at any time in Settings.
Once you register, we send a verification email — click the link within 24 hours to activate your account. After you confirm, you may receive a follow-up email with a direct link to download the app and start learning. Your free-tier access begins immediately, so you can explore the app right away. If you do not receive the verification email, check your spam folder or use the resend option on the login page.
Yes — you can sign in with Google. Tap "Sign in with Google" on the login screen. If this is your first time signing in with Google we will create an account for you using the Google email and profile. If you run into issues, contact support and include the email shown by Google.
We currently support 15 languages: Arabic, Dutch, French, German, Greek, Hindi, Italian, Japanese, Korean, Mandarin (Chinese), Polish, Portuguese, Russian, Spanish, and Swedish. More languages may be added in future updates.
CEFR (Common European Framework of Reference) is the international standard for measuring language proficiency, from A1 (complete beginner) to C2 (mastery). When you set your level, all content — reading articles, grammar drills, conversations — is automatically calibrated to match. You can change your level anytime as you progress.
The interactive study tools — spaced-repetition flashcards, AI conversation practice, listening drills, grammar puzzles, reading comprehension, pronunciation feedback, and daily streak tracking — are available exclusively in the mobile app. Download it free from the App Store (iPhone) or Google Play (Android). The website is used to create and manage your account, and also offers free reading material: a blog, step-by-step language learning guides at sciencebasedlearning.com/learn, and a learning techniques library — all accessible without an account.
