Write one line about your day in English. Prubi turns it into natural Korean you would actually say, shows how it sounds and what each part means, and reads it in a native voice.
Prubi
Prubi is an AI-powered cloud note service and Personal Wisdom OS. Save your notes, photos, documents and schedules in your own private account, and let Prubi AI help you retrieve past records, organize what you wrote today, and review the schedule you saved for the days ahead. Free and paid subscription plans are available.
Sensitive records — passwords, account numbers, a photo of your ID — go in the personal vault. Entries and their attachments are encrypted on your device with AES-256-GCM before upload, so the server keeps only ciphertext plus the salt and IV needed to decrypt it. The key is never stored, so what the server holds cannot be read on its own; if you forget the vault password, only a recovery key you made in advance can reopen it.
Write one line about your day in English. Prubi turns it into natural Korean you would actually say, shows how it sounds and what each part means, and reads it in a native voice.
No lists to memorize. The Korean comes from what you wrote today — the line you actually want to say.
Listen in a native voice, slow it down, read along out loud, then hide it and write it yourself. Real Native voices sound closest to a real person.
It's an AI draft — depending on the situation and who you're talking to, another phrasing may sound more natural. Switch the tone or ask for a new version.
I finally finished my report, so I treated myself to a latte.
드디어 보고서 다 끝내서 나한테 라떼 한 잔 사 줬어.
deu-di-eo bo-go-seo da kkeun-nae-seo na-han-te ra-tte han jan sa jwo-sseo
드디어 = finally · 보고서 다 끝내서 = finished the whole report, so · 나한테 = to myself · 라떼 한 잔 사 줬어 = bought (myself) a latte — casual, to a friend
An example — your card is made from your own line.
1. Write one line about your day in English — the way you would tell it.
2. Pick who you would say it to: a close friend, a shop or service staff member, or someone older. Prubi matches the Korean politeness to that person.
3. Listen in a native-sounding voice, slow it down, read along out loud, then hide it and write it yourself.
No — it's a journal and notes app. Your line becomes a natural Korean draft with its meaning and each part explained, so you understand what you are saying. For anything important, check it with a native speaker.
You choose who you are talking to. A close friend gets casual Korean (banmal), a shop or service staff member gets the polite -yo form, and someone older or your boss gets the respectful form.
Yes. Listen as many times as you like, slow it down, and read along out loud. Real Native voices in Premium sound closest to a real person.
Writing your line, getting the Korean card and listening are free. Premium adds Real Native voices and lets you review all your saved lines at once.
