Sprak

From språk — Swedish for language.

Write in your language.
They read it in theirs.
Your real chats become your study deck.

A messenger for families and friend groups that span languages. Real‑time translation, voice playback, dictation — and the words you actually use with the people you actually talk to quietly become flashcards. No abstract textbook lists.

Write in English.
They read it in Italian.
Or Dutch. Or French.

Every message is translated as you send. The recipient reads it in their language; the original is always one tap away. Swipe sideways on any message to flip through the translation languages you've selected.

Pick the languages
you want to read in.

This is where you choose which languages incoming messages get translated into. Add as many as you like — they're the ones that show up when you swipe a message.

Each pack is ~30–40 MB and lives on your device. Remove any time.

· 03   Dictation & auto‑detect

Speak. We write.
In whichever language you happen to be in.

Tap the mic and start talking. The send‑in language picker tells dictation which of your languages to expect — flip the flag and you're dictating in a different one.

When you type, you don't have to pick anything: Sprak auto‑detects the language you're writing in, even if it's different from the one currently selected.

· 04   Group chats

A group chat
where everyone speaks
their own language.

Aunt Maria writes in Portuguese. Cousin Sara reads it in Swedish. The teenagers chat in English. Nobody has to be the family translator any more.

· 05   Language learning

From a chat
to a flashcard.

Two ways to save vocabulary while you're chatting:

  • tapSingle‑tap a word to add that word on its own.
  • holdLong‑press the message bubble to save the whole phrase.

Both land directly in the matching Learning Track — Sprak knows the language, so nothing to file. From there: spaced‑repetition queue, daily session, listen‑and‑repeat with pronunciation feedback.

· 06   Live dictionary

Words you're studying,
underlined as you read.

Any word that lives in your phrasebook is gently underlined wherever it appears in your chats. Tap it and a dictionary card slides up — definition, the message you originally captured it from, and a shortcut to the full study card.

Reading becomes review without breaking the flow of the conversation.

Add a learning track — choosing learning & reference languages
Add a learning track — second variant

· 07   Tracks & reference languages

Learn German from English.
Learn Japanese from Chinese.

Every learning track has its own reference language — the one you already speak that translations and definitions appear in. If you're comfortable in English and Chinese, each track can use whichever feels more natural.

One person can run several tracks at once, each anchored to a different mother tongue.

· 08   Bundles

Send vocabulary
like a mixtape.

Built for the moment a language teacher or a conversation group wraps up a session: bundle the words and phrases you covered, send it to every student, and they review it on their own time — each entry lands directly in their phrasebook and learning queue.

Also: a hand‑picked stack for your kid before a school trip, for a friend learning your language, or for yourself before a flight. The metaphor is a cassette; the format is a study deck.
