Just ask out loud and hear the answer — the world explained through things you already know. Only the facts, never made up. Now with a warmer, natural voice.
40 answers your questions out loud — and only with the facts. Ask anything by voice, and 40 explains it in plain language, using places and things you already know. How big is a lake? 40 might tell you it's "about 60 times the size of Central Park."
Why 40 is different:
• Facts first. 40 checks a verified knowledge base before answering and shows you the source. If it doesn't know, it says so — it never makes things up.
• Made for listening. Big buttons, a clear voice, answers read aloud — easy for everyone, including older adults.
• Explained your way. Sizes, heights and distances become familiar comparisons, so they're easy to picture.
• Live World Cup. Ask about the 2026 World Cup — scores, players and records, kept up to date.
• Your language. Use 40 in English, Traditional Chinese, or Simplified Chinese.
Just tap the microphone and ask.
A warmer, more natural speaking voice — and better at understanding seniors: pausing mid-question no longer cuts you off.
