Product statement
is a language-learning app designed to help users learn a new language through reading books.
The app offers an immersive, engaging experience that encourages users to learn in context, helping them understand vocabulary, grammar, and sentence structure while reading real books. Booklet is designed to complement traditional language-learning methods like language classes and apps such as Duolingo, targeting language learners who prefer reading as a learning method.
Core Value Proposition
- Immersive Learning with Books: Users learn by reading the books they love, rather than isolated vocabulary or grammar exercises.
- Reading assistance: Users can instantly translate any word or phrase they encounter while reading, and specify which words they want to learn or don't want to learn.
- Contextual Understanding: Vocabulary and grammar are learned in the context of real language usage, making learning more effective and enjoyable.
- Personalized Learning Experience: Tailored exercises, translations, and progress tracking to suit the user’s learning pace.
How does Booklet differ from …?
: Duolingo is an excellent app for practicing languages, but focuses on structured exercises and gamification rather than reading books. Booklet complements Duolingo by offering a way to practice language learning through reading, which is what users love most, and appeals to users who enjoy reading.
: Kindle is a great platform for reading e-books, but it doesn't cater to language learners. It doesn't offer easy translation or the ability to practise language skills. Booklet, on the other hand, allows users to quickly translate words and phrases as they read and provides exercises to reinforce learning.
Target Audience
Primary audience
- Language learners who love to read** or understand the importance of reading to improve their language proficiency.

Demographics
- Age Range: 15-40 years old, spanning teenagers, university students, and working professionals. These individuals are typically tech-savvy and comfortable using mobile apps for educational purposes.
- Language proficiency: Learners at an A2 to B2 . Absolute beginners may find the complexity of reading books challenging, while those at a higher proficiency level may not require Booklet's support.
