Khaya focuses on speech recognition and pronunciation across Ghanaian languages, teaching you how to say something correctly. Google Gemini, ChatGPT Voice, and other mainstream assistants can handle questions in Twi and English but don't understand natural code-switching, the way most Ghanaians mix languages in the same sentence. Nkomo is built for that natural mixing, and it keeps your privacy explicit and in your control.
Kofi was driving through Kumasi traffic when his sister called. She had a question in Twi about a bank application deadline. She needed to know exactly when to submit it and what documents to include. Kofi had read the details in English on his laptop that morning, but now he was in traffic with maybe two minutes before the light changed. His sister wouldn't have waited for him to type a careful response anyway.
He could have pulled out his phone and opened one of the mainstream assistants. But the moment he tried to answer in the natural way he'd speak to his sister ("Ebe next Friday oo, but yoo check the form for the full list of documents") the assistant would either ask him to pick one language or it would misread what he'd actually said. It would split the languages into separate thoughts instead of understanding them as one continuous idea. Khaya would give him perfect pronunciation feedback if he practiced the Twi words, but it's not designed to carry on a conversation. It teaches you; you don't talk to it.
With Nkomo, he held the phone to his ear, spoke naturally in the mix his sister would hear from him, and heard back a response that helped him explain what she actually needed to do. The assistant understood the Twi and the English as one thought.
His sister got the deadline right. But more than that, Kofi didn't have to stop the car, restart his brain into one language, or pretend to speak a different way than he actually speaks.
What Khaya teaches you: pronunciation and recognition
Khaya's purpose is clear from what it does. You say something in Twi or another Ghanaian language, and it gives you feedback on how you said it, where your pronunciation needs work, where your tone shifts. It's built for learning and practice. If you're working to improve your Twi pronunciation or you're helping a child learn the language, Khaya is exactly what you're looking for. It's not trying to be a conversational partner.
Mainstream assistants: powerful but demanding one language at a time
Google Gemini, ChatGPT Voice, Meta AI, and similar tools can do a lot. They can answer questions, help you draft something, reason through a problem. For most Ghanaians, the issue isn't that they don't work in Twi or English individually. The issue is they assume you will pick one. Code-switch mid-sentence and they stumble. They treat your Twi and English as separate inputs instead of as one natural stream of thought.
They also treat everything you tell them as training data. That's how they learn. It's also why most ask you to agree to terms where your conversations can be used to improve the model. For some people, that's a tradeoff they're comfortable with. For others, the fact that your private family matters, your health questions, or your work problems are being collected is reason enough to look elsewhere.
Nkomo: built for the way you actually code-switch
Nkomo was designed specifically for people who speak both Twi and English naturally, mixed in the same breath. You don't have to pick a language before you speak. You don't have to mentally translate yourself into one lane and stay there. With Nkomo, you speak the way you actually speak. The assistant understands it, and you can use it hands-free, holding to speak and interrupting naturally the way you would in a real conversation.
The other core difference is privacy. Nkomo is explicit about what stays on your device and what reaches the cloud. You set it once (never, ask each time, or just this session) and your history is kept where you decide it should be. If you turn off cloud storage, your messages are purged immediately. You can export all your data or delete your account with a single tap. None of that is buried in fine print. It's right there in the app.
Kofi didn't have to think about any of that when he answered his sister. He just spoke. But the architecture underneath was built from the start to keep his family conversation private by default, not as an afterthought or a setting he had to hunt for.
