AI Prolocutor — The AI Agent That Places Phone Calls for You Phone calls take time, attention, and emotional energy. Restaurants need to be booked. Customer service needs to be argued with. Reservations need to be rescheduled. AI Prolocutor turns each of those calls into a 30-second briefing — then places the call for you while you watch. HOW IT WORKS Tell AI Prolocutor what you need in plain words: "Book Sushi Ono for two at 7:30 tonight, no allergies, ask about parking." The Preparation agent organizes the request, searches for the place if needed, and produces a structured briefing. Tap to call, and the AI handles the conversation in real time using the voice model you selected. Whenever something comes up that was not in the briefing — the restaurant asks for your phone number, customer service asks for an order ID — the AI pauses, surfaces the question on screen, and resumes the moment you tap an answer. EIGHT SCENARIOS, READY TO GO · Restaurant reservations · Hotel bookings · Beauty and spa appointments · Fine payments and appeals · After-sales and refunds · Government services · Cross-language calls · Savings and negotiations Each scenario has its own preparation flow and conversational style, so the AI sounds appropriate to the context — relaxed at a café, firm with customer service, formal at a government office. CHOOSE YOUR AI MODEL · Qwen 3.5 Omni Realtime — strong Mandarin, fast in mainland networks Switch any time depending on language, latency, or voice preference. REAL-TIME INTERVENTION When the AI does not know an answer, it does not invent one. It pauses, asks you on screen, and waits. Tap a quick answer or paste a fact — the AI continues the call seamlessly in your voice. WORKS WITH KIKAGO BLUETOOTH (OPTIONAL) Pair the Kikago Bluetooth audio dongle to route an actual phone call through AI Prolocutor — the AI speaks directly to the other party while you stay silent. Or use software-only mode for practice, demos, and learning the flow. LANGUAGES Native call experience in Mandarin Chinese, English, Japanese, Korean, French, German, Spanish, and Thai — with first-class cross-language handoff. PRIVACY YOU CAN VERIFY · Call transcripts and recordings stay on your device · Audio is streamed only to the AI provider you chose, for the duration of the call · No advertising tracking, no contact-list access, no cross-app tracking · Apple Speech Recognition runs on-device when selected WHO IT IS FOR People who would rather do anything than make a phone call. Travelers and expats handling local services in another language. Caretakers helping parents with appointments. Anyone tired of waiting on hold to argue about a refund. Download AI Prolocutor and never dial alone again.

Most money apps want eleven fields before they'll let you save anything. LemonBook wants one. Tap Money Out or Money In, type the amount, done. Merchant, category, date, note, receipt — all optional, all addable later. The point is that you actually record things, not that you record them perfectly. SIMPLE BY DEFAULT - Two taps from opening the app to a saved entry - One detail is enough — an amount alone, or just a name, or just a photo - Money in is mint, money out is coral. You can read a month at a glance. - Come back and fill in the rest whenever you feel like it SAY IT NOW, FILE IT LATER "Hey Siri, capture an expense in LemonBook." Siri asks how much. That's the whole interaction — no unlocking, no opening the app, no choosing a Book while you're holding a coffee and a receipt in the same hand. The amount lands in your Siri Inbox, which is a holding area rather than a Book. Next time you open LemonBook it's waiting on the Today tab, and you decide where it belongs. Nothing gets filed somewhere wrong because you were in a hurry. It's the same idea as the rest of the app: capture now, organize later. Voice just makes "now" faster. YOUR LEDGER, THE WAY A LEDGER SHOULD WORK - This month, last month, this year, or everything — with a running net - Search merchants, categories and notes - Month-by-month sections, so a long history stays readable - Categories with their own colors, or no categories at all - Loose ends — a quiet list of entries still missing a detail, if you want it PRIVATE BY DESIGN Your entries sync through your own iCloud account. LemonBook has no server, no sign-up and no login — there is no account for us to lose. Nothing you write is sent anywhere else, and no AI reads your receipts. Sync is included for everyone, free and Plus alike. LEMONBOOK PLUS — one purchase, not a subscription - Unlimited Books — keep business, personal and travel apart - Attach receipts and PDFs to any entry - Export to CSV, or a PDF packet for tax season - View several Books together, or merge two into one - Richer summaries LemonBook Free is not a trial. One Book, unlimited entries, unlimited categories, full search and filters, Siri capture, and iCloud sync — all yours, permanently. Plus is there for when your little book grows. Made by IMPLEMON.
