## What is FlowLingua?

Other apps make you click. We let you read.

FlowLingua is a bilingual reader that turns any foreign-language book into a bilingual book. Import your own books, articles, videos and audio — or start with the ready-made content in the library.

Read and listen to foreign-language content as if it were your native language. Every word and every sentence is already translated — synced to the audio, with no clicking at all. No dictionary, no vocabulary drills, no loss of flow.

It is the digital heir of the interlinear tradition — the bilingual books and parallel-text editions of Ilya Frank, but without the page flipping, and for any book you choose.

▸ WHAT FLOWLINGUA DOES

• Automatic bilingual reading — the Birkenbihl method in its purest form: every word of your book sits right under the original, including grammatical structure.
• Translated sentence by sentence — plus the natural sentence translation, so nothing stays unclear.
• Synced to the audio — text and original audio run word by word together (karaoke principle). You train pronunciation, rhythm and listening comprehension.
• Import your own content — EPUB, PDF, DOCX, YouTube videos and audio files are decoded and translated automatically.
• Easy reading — a dedicated Birkenbihl mode for relaxed, uninterrupted reading.
• Vocabulary tracking — unknown words come pre-marked; you remove the mark once you know them.
• Shadowing & speaking practice — repeat sentences right after native speakers, with sentence repeat.
• Learn offline — download content and keep learning anywhere. Progress syncs automatically.
• 20 languages — from English, Spanish and French to less common languages.
 • Listening-Reading (L-R) without the three-window setup — one screen.

▸ HOW IT WORKS

1. Import — bring your own book, video or audio, or pick ready-made content.
2. Understand — everything is already translated, word by word and sentence by sentence.
3. Stay in flow — press play and let the audio guide you. The translation is there when you need it.

▸ WHO IS THIS FOR?

• You want the books you actually care about as bilingual books — without flipping pages or clicking every word.
• You want to read foreign-language books and understand them right away.
• You know the Birkenbihl method and finally want a tool that decodes automatically.
• You come from a reader where you have to click every single word — and you're done with the clicking.
• You've drilled vocabulary and still never understood a real book.

▸ WHY FLOWLINGUA EXISTS

I wanted to learn languages — but memorizing vocabulary and grammar put me off. So I researched how polyglots really do it: understand, don't memorize. That's why I built FlowLingua as an app.

FlowLingua combines three proven input methods: the Birkenbihl method (decoding), Listening-Reading (listening and reading at the same time) and Comprehensible Input by Stephen Krashen (understandable content that interests you).

▸ SUPPORTED FORMATS

EPUB · PDF · DOCX · YouTube · MP3 & audio files

▸ FREQUENTLY ASKED QUESTIONS

Can I use FlowLingua as a bilingual book reader?
Yes — import any EPUB, PDF, video or audio file and FlowLingua turns it into a bilingual book: original and translation together, word by word and sentence by sentence, synced to the audio. The library also has ready-made content to start with.

Do I need prior knowledge?
No. The word-for-word translation makes texts understandable even if you don't know a single word yet.

How is this different from vocabulary apps?
You learn with real books, videos and audio — not quiz exercises. Understanding comes first.

Does it work offline?
Yes, content can be downloaded.

Stay in flow. Not in the dictionary.
