It was a Tuesday night in our kitchen. The kettle had just clicked off. Hannah was standing by the counter holding her phone out to me with the screen up, the way you hold up a moth you found in the bathroom. A WhatsApp voice note was playing on loop. My mum's voice. Forty-seven seconds.
"What is she saying," Hannah said. Not a question. A small, tired plea.
I listened. Mum was telling Hannah something. Half the sentence was in Hindi. A third was English. The rest was a kind of warm in-between that's not really either — the actual language my family speaks. There were three different words for "you" in there, each one carrying a different temperature of respect. There was a joke. There was a question Hannah was supposed to answer.
I translated it. Hannah nodded. She typed back a polite English reply with one heart emoji, because that is what you do when you have no other option. Then she put the phone face-down on the counter and said, very quietly, "I want to be able to do this myself."
That was the night. Not the dramatic one. Not a wedding or a Diwali or a phone call gone wrong. Just a kettle, a voice note, and a woman I love deciding she was tired of being the one person at the table who needed subtitles.
What we tried
Hannah is, for the record, very good at trying. She is the kind of person who finishes books. So when she said she'd learn Hindi, I believed her, and I bought her every reasonable option on the market.
Duolingo Hindi was the obvious first stop. The streak got her to day 47. I have the screenshot. She learned the Devanagari script — actually learned it, can sound out a roadside sign in Delhi — and a small vocabulary of nouns that have not, to my knowledge, ever come up in a real conversation with my family. Elephant. Mango. Newspaper. The gamification was the problem, weirdly. Every time she missed a day, the green owl would send her a notification that felt less like encouragement and more like a small accusation. Hannah wasn't learning Hindi for fun. She was learning it because in three months she was going to be sitting on a sofa across from my Nani, and Nani does not care about your streak. The guilt loop made it worse, not better. After about seven weeks she muted the notifications, then deleted the app, and felt like she'd failed at something she hadn't even started.
Rosetta Stone Hindi came next. The pictures-and-immersion thing is genuinely lovely for some learners. For Hannah it was like being handed a beautifully bound dictionary when she needed a phrasebook. There was no shortcut to "what do I say when my future mother-in-law offers me a third roti." It taught her the word for "boy" and "girl" and "the boy eats an apple," which, with respect, is not how anybody talks.
Pimsleur Hindi was the third try. Audio-first was closer to what she needed. She liked the rhythm of it, listened on walks. But the Hindi it teaches is what I'd call newsreader Hindi — the formal, slightly stiff register you'd hear on Doordarshan in 1994. My family does not speak newsreader Hindi. Nobody under 70 does. When Hannah tried a Pimsleur sentence on my brother over FaceTime, he laughed and said "are you reading this off a teleprompter."
Each one had a sliver of what she needed and a mountain of what she didn't.
I want to be clear: these are good products. Duolingo has taught more people more languages than any tool in human history. Rosetta Stone built the entire category. Pimsleur is genuinely excellent for the slow, deep learner. None of them were built for a 33-year-old British woman who needed to be in conversational shape for an Indian family WhatsApp group by autumn. That's a niche of one. Nobody was going to build it for her.
So I sat with that for a while. And then I started building it for her.
The gap
Here is the thing nobody tells you about Hindi: there are at least three of them, and Hannah needed the third.
There is textbook Hindi — the Hindi of grammar drills, Sanskrit-derived vocabulary, and sentences about elephants. This is what almost every app teaches, because it's clean, rule-based, and easy to test. It is not what gets spoken at a dinner table.
There is spoken Hindi — the actual everyday register, looser, faster, full of contractions and English loanwords that have been Hindi for so long that calling them English feels wrong. "Train," "ticket," "office," "scene." This is closer to what Hannah needed, but most apps don't teach it because it's harder to systematise.
And then there is Hinglish — the actual operating language of urban Indian families in 2026 and of basically every Indian diaspora WhatsApp group I have ever been in. A typical sentence from my mum: "Beta, can you tell Hannah ki the function is on Saturday, and bring something nice to wear, okay?" — where "beta" is a warm word for someone younger and "ki" just means "that". That's one sentence. Three languages of grammar in it. No Hindi app teaches this because no Hindi app's curriculum team thinks of it as Hindi. But it is the Hindi that 400 million people actually speak when they are relaxed.
There are maybe thirty phrases that, if a non-Indian partner can deliver them with the right intonation, will disarm any aunty in any room on any continent. "Aap kaise hain" — how are you. "Khaana bahut accha tha, aunty" — the food was so good, aunty. "Mujhe thodi si Hindi aati hai, lekin main seekh rahi hoon" — I only know a little Hindi, but I'm learning. None of these are hard. All of them are missing from every app I downloaded. And the stakes of getting them right — particularly the aap vs. tum vs. tu decision, which is the entire respect system of the language compressed into one syllable — are real. Calling your mother-in-law "tu" on first meeting is not a small mistake. It is the mistake.
No app was built for this because the market for "white partner of an Indian who needs to survive a wedding in Jaipur" is small. The market for "heritage learner who grew up hearing Hindi but never spoke it and now feels weird at their cousin's mehndi" is bigger but invisible. The market for "person who already passed the Duolingo Hindi tree and still cannot order food in Delhi" is, I suspect, enormous, but nobody has counted it.
I had one user. She lived in my house. I built for her.
What we built
The first decision was voice-first. Hindi has sounds that English doesn't — the retroflex t, the aspirated kh, the nasal vowels — and you cannot learn to make them by tapping word tiles. You learn them by trying, hearing yourself fail, and trying again. So Hinglish Vinglish is a speaking app. You talk to it. It listens. It scores how close you got. If your "kh" came out as a soft "k," it tells you, and it gives you the sound again, slowed down.
The second decision was Ellie.
I did not want Hannah to talk to an app. I wanted her to talk to someone. So I built her a coach: a small saffron-orange elephant with big ears and the patient, slightly weary energy of a friend who has been explaining the same joke for twenty minutes and still finds it funny. Ellie does not say "great job!" when you mispronounce something. Ellie says "hmm, close, try the back of the throat a bit more, like you're slightly disappointed in someone." Ellie has opinions. Ellie has a personality. Ellie is the reason Hannah picks up the app.
The third decision was scenarios over grammar. The app is not organised by tense or by noun class. It is organised by the actual situations Hannah was going to be in. "First meeting with the in-laws." "Compliment the food." "Polite refusal of a fourth helping." "Auto-rickshaw negotiation, Delhi version." "Replying to a voice note from an aunty about a wedding." Each scenario teaches the ten or twelve phrases you need for that exact moment, in the register you'd actually use, with Ellie playing the other person.
The fourth decision was AI scoring. Every time Hannah speaks a phrase, the app gives her a score: pronunciation, rhythm, register-appropriateness. Not a star rating. A specific note. "Your 'aap' was perfect. Your 'kaise' was a beat too fast. Try it again, but as if you've just sat down and you're not in a hurry." This is the part that took the longest to build, because off-the-shelf speech-to-text does not understand Hindi-accented English or English-accented Hindi, which is, of course, the only kind of Hindi we needed it to understand.
The fifth decision was the one I am most proud of: no streaks, no guilt trips. You open the app when you want to open the app. Ellie will not guilt you at 9pm about a broken streak. The stakes are real enough. Hannah does not need a green owl to remind her that her mother-in-law is waiting.
Where we are now
Hannah is not fluent. She is not close to fluent. But she is, for the first time, in the conversation. She can hold the first sixty seconds of any family interaction on her own. She can read a Hinglish WhatsApp message and reply with a sentence that lands. That is the milestone I cared about.
The app is rough in places. The pronunciation model still gets confused when Hannah's "th" drifts into the English th instead of the Hindi t. Ellie sometimes says "haan ji" — a polite yes — in a way that sounds vaguely sarcastic, which I have decided is a feature.
It is free to start. There is no subscription — if you want everything, it is a one-time unlock. There is no streak. There is one small elephant.
An invitation
If you are the partner of someone whose family speaks Hindi, and you have ever held a phone out at arm's length and asked them to translate a voice note — we built this for you. If you are a heritage learner who grew up hearing the language and somehow never learned to speak it, and you feel a small private shame at every family event — we built this for you too. If you have already finished the Duolingo Hindi tree and you still cannot order a chai in Connaught Place — same.
It is free to start. Ellie is in there. Try it for an hour. If it works for you, tell us. If it doesn't, tell us harder — we read everything, and the things that are broken are broken because we haven't met you yet.
