It's hard to understand an app's features just by reading them in a list. It's easier when you see them inside a situation. Here are seven real moments — the names are invented, but the problems are ones we've been hearing for months from testers and shops — where KAIXO solves something that, without KAIXO, used to get solved worse.
1. Hotel reception · "Good evening, do you have a reservation?"
Who: Marta, receptionist at an 18-room boutique hotel in Donostia. A guest arrives at 11:40 pm, tired, speaking Mandarin. Marta doesn't.
Before: the guest shows the Booking screen, Marta opens Google Translate, types the question, hands the phone to the guest, waits, reads. Five minutes to confirm the name, another five to explain breakfast and Wi-Fi. The queue grows.
With KAIXO: Marta has her phone sitting on a stand at the counter with KAIXO Direct in hands-free mode. She speaks in Spanish, the guest speaks in Mandarin — the system detects the language automatically, translates and reads it aloud through the speaker. Neither touches the screen. The conversation lasts what it should: three sentences, thirty seconds.
The trick here: hands-free Direct kills the "give me the phone, wait, now you" dance. The phone stays put, both speak, the speaker projects. It's the natural posture at any counter.
2. Restaurant · "What's exactly in this?"
Who: Joaquín, waiter at a tavern in central Madrid. A table with three German tourists; one of them points to a dish on the Spanish menu and asks something.
The problem: the menu lists "callos a la madrileña". Joaquín knows what it is. The customer doesn't — and she's also allergic to celery.
With KAIXO: Joaquín pulls out his phone, opens KAIXO Direct, and the customer asks him in German whether the dish contains celery. The phone translates to Spanish, Joaquín answers "yes, it has celery in the base", and the phone translates back. The customer switches dishes. Thirty seconds. No gesture theater.
If the menu had been chalked on a board, Joaquín could also use Photo translation: the customer points the camera at the sign, KAIXO returns the menu in German keeping the layout. Useful when you walk into a place with no printed translated menu.
3. Pharmacy · urgent allergy
Who: a French tourist at a pharmacy in Pamplona during San Fermín. He has a skin reaction and doesn't know if it's from something he ate, the sun, or a cream. The pharmacist only speaks Spanish and Basque.
With KAIXO: the pharmacist opens Direct set to Spanish ↔ French. The tourist explains his symptoms, she asks what he's taken, what he applied, whether he has a fever. Clear conversation, no misunderstandings. She decides whether to recommend something over-the-counter or send him to the health center.
This is one of the cases where testers tell us the difference really matters. "I think I understood that…" isn't the same as understanding properly before giving medical advice.
4. Transnational family · grandma and grandson
Who: Lucía lives in Boston with her parents. Her grandmother lives in a village near Salta, Argentina. Grandma speaks Spanish, Lucía only speaks comfortable English (she understands Spanish but struggles to speak it).
Before: short calls, Lucía answering in monosyllables, the parents interpreting. Conversation that doesn't flow. Grandma ends up thinking "she's not interested".
With KAIXO: text chat and video calls with real-time translation. Lucía writes in English, grandma reads in Spanish; grandma replies in Spanish, Lucía reads in English. On video calls, live subtitles appear as they speak. Lucía starts to understand more Spanish by hearing it subtitled, and she dares to drop loose phrases. The conversation, after a couple of months, flows.
There's a detail we often overlook: KAIXO isn't just a translator. Simultaneous translation with visible subtitles helps you learn the other person's language, almost without meaning to. It's a side effect we see in mixed families.
5. International business · the order to Tokio
Who: Pablo, importer in Lima of a brand of Japanese kitchen utensils. He deals directly with the manufacturer in Osaka. His contact, Hiro-san, writes English only middlingly; Pablo doesn't speak Japanese.
Before: emails in simplified English, "stock available?" type phrases, misunderstandings about quantities, delays from back-and-forth.
With KAIXO: Pablo and Hiro-san communicate by chat. Pablo writes in Spanish, Hiro-san receives it in Japanese. Numbers, dates and product references stay untouched (KAIXO doesn't translate digits or codes). When they need to talk — payment, shipping dates, an issue — they do a video call with live subtitles. The professional relationship gets smoother and bigger orders close with less friction.
For quick conversations at events (fairs, trade visits) they use KAIXO Direct: phone on the table, both speak, no interruptions.
6. San Fermín · the lost tourist
Who: Australian family, first time in Pamplona, arriving in July at 6 a.m. and unsure where their apartment is. All they have is an address scribbled on a piece of paper.
With KAIXO: on the street they approach a neighborhood resident. They open Direct, ask for directions. The neighbor, who only speaks Spanish, explains it's three streets to the left, that they pass through the green doorway, and the access code is right next to it. Thirty seconds. A normal conversation, not a pantomime.
If instead they see a sign with instructions (a map of the area, the rules of the bull run, public-transport timetables), they can use Photo translation: photo of the sign and they get the English version without losing the format.
If you're heading to Pamplona for San Fermín and you're coming from abroad, our recommendation is: download KAIXO before the trip, set your language, and try Direct at home. The first time you need it isn't the right moment to learn how it works.
7. Tour guide · group of six, five languages
Who: Ainhoa leads a group through the old town of Bilbao. Six people: two Italians, one French, one Japanese, one German, one Brazilian. Ainhoa speaks Spanish, English and a little French.
The problem: repeating every explanation in three languages is slow and excludes anyone who understands none of the three. With professional translator headsets the cost explodes.
With KAIXO: Ainhoa opens a group chat in KAIXO with all six. Before each important explanation, she writes the text in Spanish. Each person receives it in their language — Italian, French, Japanese, German, Brazilian Portuguese — automatically. Ainhoa explains the lighter stuff orally in Spanish and uses the chat for the "lookup" details: schedules, street names, historical facts. The group appreciates it, especially the Japanese man, who tended to be left out of the conversation.
For small one-on-one chats with anyone in the group (someone asks Ainhoa something at the end of the tour), she switches to Direct. And Latidos — KAIXO's integrated social feed — lets her post the day's tour photos at the end so each client sees them with a caption in their own language. Easy retention with no extra effort.
Which feature for which situation
Useful summary:
- Face-to-face conversation with someone who doesn't have the app: KAIXO Direct (push-to-talk or hands-free).
- Sign, menu, paper, medical prescription, product label: Photo translation.
- Text messages with someone far away: KAIXO chat with automatic translation.
- Calls and video calls: KAIXO with live subtitles.
- Multilingual groups: group chat (each reads in their own language).
- Publishing for an international audience: Latidos with automatic post translation.
What we don't solve
KAIXO isn't magic. There are things we say honestly:
- It needs internet. Wi-Fi or data. Without a connection it can't operate.
- Very strong accents or extreme noise lower transcription accuracy. In a market at 1 p.m. you need to speak with the phone close to your mouth.
- Languages with little digital representation (some regional variants, minority languages) have lower translation quality. Our focus is on 15 major languages.
- Humor, idioms, metaphors sometimes get lost — as with any automatic translation. For technical or formal conversations it works very well; for local jokes you have to accept a certain flatness.
When we say this: when someone asks us "does this work for my case?", we'd rather be clear. If your case is one of the seven above, you'll feel the difference from the first use.
FAQ
Do I have to pay to use it? There's a free plan with a daily quota enough for moderate personal use. For intense professional use (hotels, restaurants, guides) there are B2B plans with expanded quotas, and the option to top up balance when the monthly quota runs out.
What if I'm the one traveling, not a business? Same free plan, same features. Direct, Photo translations and chat all work the same.
Does KAIXO replace a professional translator? For day-to-day conversation, yes. For legal documents, sensitive contracts, high-level conferences: use it as support, not as the sole source. Automatic translation is very good, but it doesn't replace a certified sworn translation.
Are my conversations saved? Direct audio is processed in the moment and not stored persistently. Chats, like in any messaging app, are stored on your device. Full privacy policy here.
How many languages does it work in? 15: Spanish, English, French, German, Portuguese, Italian, Basque, Chinese, Japanese, Arabic, Hindi, Russian, Korean, Turkish and Indonesian.
