What I learned:
— Users didn't understand the app in the first 3 seconds
— Voice input stopped automatically (browser default) → users lost trust
— Pro/Perso buttons always visible = cognitive load for new users
What I shipped this week:
— Onboarding carousel (3 slides, swipeable, shows exactly what to do)
— Push-to-talk mic (WhatsApp style — hold to record)
— Rotating suggestions under input instead of static buttons
— Receipt attachments (Pro) — photo or PDF per transaction
— Email export via Resend (PDF + CSV + receipts)
— Multi-country VAT (10 countries including USA)
— FR/EN auto-detection based on country
