Write one line about your day in English. Prubi puts it in the Japanese people actually use, shows what each part means and how to read it in kana, and reads it aloud 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.

No list to memorize. The Japanese comes from the line you wrote today, so it is the thing you actually want to say.
Listen in a native voice, play it slowly, read along, then hide it and write it yourself. The wording changes with who you are talking to — casual with a friend, です/ます with a shop clerk, keigo with someone older.
It is an AI draft. Depending on the moment and the person, another wording can fit better. Change who you are speaking to, or make it again.
