Flashcards in WhatsApp, the chat you already check 50 times a day becomes the study habit. Drop in the vocab from your last lesson, or snap the handout, and the words drip back between sessions with native-speaker audio, quick check-ins, and gentle corrections.
By session four, your tutor notices you remember most vocabulary. And you don't feel like you are actively studying.
$6/mo, first 7 days free. Reply ‘stop’ before day 7 and you’re never charged. WhatsApp only, nothing to install.
You showed up to class. Your tutor was patient. You scribbled words to remember and promised yourself you’d review them on Sunday.
Sunday becomes Tuesday. Tuesday becomes “I’ll look it up if it comes up again.” By the next session, your tutor is re-teaching last week’s words and you’re paying $30 an hour to revisit ground you already covered.
That’s not a learning problem. It’s a between-sessions problem. The hours between lessons are where your tutor’s work goes to die.
Here’s what changes: the words from your last lesson slide into WhatsApp, which you check 50 times a day anyway. You hear the native-speaker pronunciation, reply easy or hard, the ones you fumble come back, reviewing costs 30 seconds at a time. You walk back into class knowing the new words, and your tutor finally gets to push you forward instead of looping back.
Same WhatsApp contact. Pick your language, switch any time.
Set up once. Then let the gaps between lessons do the work.
Paste your tutor’s list, snap the handout, or accept the deck your tutor sent you in Pinguingo. Spaced repetition is built in, you don’t schedule a thing.
One link. One reply. Nothing to install. Pinguingo lives as a single contact in the messenger you already check 50 times a day.
Words drip in during the windows you choose, with native-speaker audio attached. Reply easy/hard, ask “how do I say…?” The ones you fumble come back until they don’t. By the next session, your tutor notices.
Your tutor’s vocab, dripped back to you in the chat you already check 50 times a day. By session four, your tutor stops re-teaching last week’s words.
Tell the bot how each word felt. Easy slows it down; hard pulls it forward in the queue. The words you fumble come back until they don’t. No streak, no guilt, just spaced repetition under the hood.
Just message Pinguingo. “How do I say…?”, “is this right?”, “rewrite this nicer.” Answers in your target language and in English, instantly, instead of saving it for a $30 =our with your tutor.
Three a day, mornings only, weekdays only, exactly at 8:14am, you set the pace.
Pick your active windows. Pinguingo is dead silent the rest of the day. We never send ‘you missed today’, because there’s nothing to miss.
Every word and example sentence arrives with clean audio in a native voice. Tap once, hear how it actually sounds, no IPA chart, no YouTube rabbit hole.
Your tutor’s WhatsApp handout. The whiteboard photo from last class. A textbook page. A menu you photographed on your last trip. Pinguingo reads the page, translates the vocabulary, and weaves it into your daily chats.
Your tutor’s handout, the whiteboard, a textbook page, a screenshot of the WhatsApp message they sent. One photo.
We translate everything in seconds. Tap to keep the words from class you actually want to nail. Skip the ones you already know.
The words drip back into your WhatsApp through the week with native audio, quick questions, mini-conversations. Not flashcards. Real use.
Your tutor teaches. Pinguingo makes it stick. Each piece below already exists as its own paid product; we pay for the underlying tools so you don’t. The whole stack lands in the chat you already check 50 times a day.
