Stop taking notes. Start being present. Convoxa doesn't just transcribe what's said. Snap the whiteboard, drop in the deck, jot a thought — while it's still recording — and it weaves all of it into one note: what was discussed, what was decided, what you said you'd do. LIVE NOTES Meetings aren't only spoken. Someone shares a deck, sketches something on a whiteboard, sends a PDF nobody reads out loud. Add it mid-recording and it doesn't sit at the bottom of the note as an attachment — it becomes context. A photo of a whiteboard is read and written into the note alongside what people were saying about it at the time. THE TIMELINE UNDERNEATH Every line is timestamped. Tap one to hear exactly how it was said, so nothing in the note has to be taken on faith. TWO WAYS TO TRANSCRIBE Cloud transcription handles 60+ languages and labels who said what. On-device transcription runs completely offline, using your iPhone's built-in speech recognition. A NOTE YOU CAN ACTUALLY EDIT The note arrives formatted: headings, paragraphs, bullets, numbered lists, checklists. Underneath that is a full rich text editor, not a read-only recap. Rewrite a line that missed the point. Tick off action items as you finish them. Highlight, color, restructure. Your edits are yours and stay exactly where you put them. ONE PRESS TO START Action Button, Siri, Lock Screen, or Control Center. Start at the beginning of a meeting or halfway through — long meetings, quick calls, or a thought in the car. Recording starts before the moment passes. CONFIDENTIAL BY DEFAULT On-device transcription never sends your audio anywhere. It doesn't leave your iPhone, because it never needs to. If you choose cloud transcription for accuracy or language coverage, the audio is deleted the moment it's processed. It is never stored, never shared, and never used to train anything. Neither are your notes — they aren't read, kept, or fed into any model. AFTER THE MEETING Every note is searchable from Spotlight without opening the app. Export as plain text, Markdown, or PDF. Everything syncs privately over iCloud, so a meeting recorded on your iPhone is on your iPad before you sit down with it. PRICING Free to try, with recording hours included in every mode — cloud transcription included, nothing held back to a preview. Convoxa Pro is a monthly subscription that unlocks unlimited on-device transcription and 20 hours of cloud transcription each month. Payment will be charged to your Apple Account at the confirmation of purchase. Subscription automatically renews unless it is canceled at least 24 hours before the end of the current period. Your account will be charged for renewal within 24 hours prior to the end of the current period. You can manage and cancel your subscriptions by going to your account settings on the App Store after purchase.

LumenDoc turns receipts, bills, medical letters, warranties, contracts and everyday paperwork into a searchable document library. Scan a page, let AI Vision extract the details, track what you spend, and turn important dates into reminders or calendar events. WHY LUMENDOC SCAN PAPERWORK FAST Capture receipts, bills, IDs, school forms, appointments and important letters with your iPhone camera. LumenDoc extracts text, dates, amounts, vendors and document categories so your library is useful from the first scan. ASK YOUR DOCUMENTS Instead of digging through folders, ask questions like: - When is my appointment? - How much did I spend at Coles? - Where is the warranty for my appliance? LumenDoc answers from your own scanned documents and links back to the source. TRACK SPENDING FROM RECEIPTS AND BILLS Receipts, invoices, bills and fines can feed a spending dashboard automatically. See totals, merchants, categories and trends without connecting a bank account. REMINDERS AND CALENDAR INTEGRATION Turn due dates, appointments, renewals and expiries into reminders or calendar events so bills, warranties, appointments and important follow-ups do not get lost. DESIGNED FOR PRIVACY Your scanned page images stay on your device after AI Vision OCR. LumenDoc sends document images to Google Gemini through our private backend only when AI Vision is used for scanning. Library Ask sends relevant OCR text excerpts, not your page images. Your data is not used to train AI models. FREE AND PRO Free includes 5 lifetime AI Vision scans and 15 lifetime Library Ask questions. Free counters do not reset. LumenDoc Pro includes 100 AI Vision scans per subscription cycle, unlimited Library Ask, full spending history and private iCloud backup. After a Pro user's AI Vision quota is used, scanning continues with on-device OCR until the quota resets on the billing anniversary. Subscriptions are managed by Apple through the App Store. Cancel any time in iOS Settings. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://lumendoc.net/privacy
