One word.
Every language you speak.

Most apps make you rebuild the same vocabulary for every language pair. ParallelLingvo keeps one concept — with all its translations, sentences and pronunciation — in a single card. Learn a word once, progress in three languages at the same time.

AI-built lessons — give it a word, a list or a topic; it builds translations, examples and a ready lesson.
Learning you can guide — parents assign lessons, set priority and see each child's progress.
One concept. All your languages. — a single concept links to several languages at once, not separate pairs.
Built for teachers — mixed-language group? Just search for the word instead of switching translators.
Connect via MCP — add words straight from any AI tool you already use through an MCP connector.
Focus on difficult words — mark tricky words and train them separately.

FAQ

Good questions

Which languages are supported?

48 at launch: the major European languages plus Mandarin, Japanese, Korean, Arabic, Hindi, Indonesian and Vietnamese. More can be added without redesigning storage.

Can I really learn more than three at once?

Yes. Translations stay attached to the same concept, so a session in one lesson moves every selected language forward.

How is it different from a flashcard app?

Flashcards are bilingual by design — one deck per pair. Here the structure itself is multilingual, and you type the word out letter by letter instead of just recognising it.

Does it work on mobile?

Yes — a mobile-first web app, an Android app, and a Telegram mini app. Native iOS is planned.
