The platform allows users to quickly add any word by typing or pasting it, or by extracting text from screenshots, photos, and real-world objects using advanced OCR and object recognition. This ensures that vocabulary acquisition is always contextual and relevant to the user's learning journey. Once words are captured, FluentBoo transforms them into smart flashcards.
Learning and practice are central to FluentBoo's methodology. Its AI Tutor provides nuanced explanations, including slang and cultural context, to ensure a deep understanding of how to use each word correctly. The app incorporates a spaced repetition system (SRS) that intelligently schedules reviews based on user confidence, maximizing long-term retention with minimal effort. Users can rate their confidence levels (Again, Hard, Good, Easy) to optimize their daily review sessions.
Beyond flashcards, FluentBoo offers a suite of tools to solidify learning. Users can generate custom stories that naturally integrate their saved words, complete with text-to-speech audio narration tailored to their fluency level. An interactive AI Tutor chat allows for real-time language practice, offering instant translations, grammar explanations, and response suggestions. Pronunciation can be mastered through Shadowing Mode, where users listen to native speakers, record their own voice, and receive instant feedback.
FluentBoo also includes various testing modes such as Multiple Choice questions, timed Word Matching games, Spelling practice, and Sentence Arrangement exercises to reinforce understanding of grammar and usage. Users can track their progress, build learning streaks, and earn achievements. The platform supports importing existing vocabulary lists from popular tools like Sheets, Docs, Notion, Anki, Readwise, Kindle, and Excel, consolidating all learning resources in one place.
FluentBoo offers a free plan with optional paid plans (Pro and Max) that provide extended usage limits for daily learning, image processing, AI discussions, premium story mode access, offline translation, and early access to new features. Subscriptions can be managed via App Store or Google Play accounts, with transparent pricing and a focus on user data privacy.
