## MochiBook Description
MochiBook is the easiest way to track expenses — just talk.

Press the mic. Say "lunch 200" or "計程車 350". MochiBook understands your voice, picks the right category, and saves the entry. Mandarin, English, mixed — all work.

Meet Mochi — your fluffy bookkeeping companion. Daily streaks feed it XP; it grows from baby to legend as you record. Every entry is a small win for both of you.

• Multi-currency: USD, TWD, JPY, KRW, HKD, EUR, GBP, SGD, CNY
• Multi-language: Mandarin, English, code-switched
• Offline-safe: recordings queue when you're off network, sync when you're back

HOW YOUR VOICE IS PROCESSED
When you hold the mic, the recording is sent over HTTPS to OpenAI's Whisper for transcription and GPT-4o-mini for parsing, via our Cloudflare Worker proxy. The audio is discarded after transcription; only the structured text entry is saved on your device. You acknowledge and accept this processing during onboarding.
