For individuals
The Japanese phone call you've been putting off? Hand it off.
Tell HayAICall who to call and what you need — in English, Vietnamese or Japanese. It calls in natural Japanese, follows your instructions, and sends you a clear result.
Works for anyone who would rather not make the call: residents, students, families, travelers — or anyone short on time.
What you can ask for
Everyday calls, handled.
Book an appointment
Clinics and dentists, salons, restaurants, offices — with your preferred days and times.
Change or cancel
Move a booking to another day, or cancel it politely.
Ask a question
Prices, availability, procedures, documents you need to bring.
Confirm or follow up
Application status, a delivery, whether a document is ready.
Opening hours
When they're open, last reception time, closed days.
Something else
Describe it in your own words — the AI works out how to say it in Japanese.
You stay in control
The AI only says what you allow — and asks before it guesses.
- Tick exactly which details the AI may share on each call.
- It says it is calling on your behalf — with a greeting and name you choose, or as an AI assistant if you prefer. It never pretends to be you, and never denies being an AI if asked.
- If they ask something you didn't provide, the AI asks you live — or tells them you'll follow up.
- Results in your language: the outcome first, then what to bring, transcript and recording.
Make your first call in a couple of minutes.
Free to start. The app is available in English and Tiếng Việt.
