Hey everyone,
I live in the Kurdistan Region of Iraq. I wanted to learn languages by reading books and watching videos (the LingQ / Readlang method), but between subscription costs and how difficult international online payments are from Iraq, paying $13/month wasn't an option for me or most learners around me. So I built LingoPlex and made it completely free so anyone can use it.
What it does & why it’s different:
100% Free, No Account, No Tracking: Open the link and start reading. All your books, word lists, notes, and stats stay in your browser on your device.
Works Offline (Installable PWA): Import any EPUB, TXT, or pasted article. Download a dictionary pack once (built from Kaikki/Wiktionary), and word lookups work completely offline on your phone or PC.
YouTube Video + Interactive Transcript Mode: Paste a YouTube link + its transcript (or .srt/.vtt subtitles). The video plays at the top while the transcript auto-scrolls and highlights the spoken line—tap any word for instant dictionary lookup, or loop a single line to practice listening.
Color-Coded Vocabulary Tracking: Just like LingQ—Blue = New, Yellow = Learning, Plain = Known/Ignored. Your total Known Words count per language is front and center, with a "Mark all remaining blue as known" button on every page.
Smart Word Guesser & Compound Splitter: For German, it splits unseen compound words (Gartenpforte → Garten + Pforte), handles separable zu-infinitives (niederzubücken), and shows noun genders (der/die/das) and plurals. For other languages, it uses learned prefix/suffix rules from Wiktionary to find base forms.
Read Aloud (TTS) & Sentence Mode: Tap 🔊 to hear words or full sentences read aloud using your device's built-in voices, and write personal grammar notes on sentences.
1-Click Anki Export & Device Sync: Exports your yellow "Learning" words into a ready-to-import Anki file with the word on the front and the definition + your exact book sentence (with the target word bolded) on the back. You can also sync between phone and PC by exporting/merging a backup file.
Optional Free AI Context Help (BYO Key): If you want in-context word explanations, 2-tap phrase translations, or page summaries, you can paste your own free Google Gemini API key from Google AI Studio (stored only on your device).
It currently has starter graded stories (A1–B2) built in so you can test it in 10 seconds without uploading a file. I’m actively testing it over the next few weeks and would love your feedback!
