You write a prompt describing what you need — like "reschedule my dentist appointment to next Friday." The AI reads your prompt, calls the number, and has a natural conversation in Japanese to accomplish your goal.
Yes. The AI can respond to questions from the person on the other end, like confirming your name, suggesting alternative times, or providing details you included in your prompt.
You'll see a complete transcript of the call in real-time. If the AI can't resolve the issue, the transcript gives you all the information you need to follow up.
No. You write everything in English. The AI speaks Japanese on the call and the transcript is shown in both languages.
Yes. Sign up, make one call — no credit card, no commitment. We want you to see how it works before you decide.
