# Hinabi > A study journal for language learners. Log sessions, visualize skills, set goals, and track growth over time. Hinabi is a free web application that helps language learners track their study habits and progress. It provides cumulative charts, skill breakdowns, streak tracking, and goal setting — all designed around consistent, lightweight logging. ## Core Features - **Session Logging**: Log study sessions in seconds — choose a skill, enter the duration, and optionally add a note about what you covered. - **Six Core Skills**: Track Reading, Listening, Speaking, Writing, Grammar, and Vocabulary independently. - **Duration & Quantity Tracking**: Log both how long you studied and what you accomplished — pages read, episodes watched, flashcards drilled. - **Active vs Passive**: Categorize sessions as production or comprehension to build both sides of fluency. - **Cumulative Progress Charts**: See your total study time grow over days, weeks, and months with interactive visualizations. - **Skill Distribution**: Identify imbalances across your six core skills to maintain well-rounded learning. - **Streak Tracking**: Build and maintain study streaks with daily heatmaps showing your consistency. - **Time-of-Day Insights**: Hourly heatmaps reveal when you study most, helping optimize your schedule. - **Goal Setting**: Set daily, weekly, or monthly targets — minutes studied, sessions completed, or hours invested. - **WaniKani Integration**: Sync milestones (Lessons, Passed, Burned) and level data from WaniKani automatically. - **Anki Integration**: Connect your Anki data to track flashcard reviews alongside other study activity. - **Any Language, Any Method**: Works with any language, any level, and any study method — textbooks, immersion, apps, tutoring. ## Links - Homepage: https://hinabi.app - Sign Up: https://hinabi.app/signup - Log In: https://hinabi.app/login
