🎙️ ZapVox turns voice messages into text, translates, summarizes and adds personal privacy tools — right in the conversation. KEY FEATURES ✓ AI transcription: click the ✍️ button next to any audio and read the text in seconds. Supports 99+ languages. ✓ Translation: translate voice and text messages — the translation appears in the bubble itself, below the original. ✓ Smart summary: long recordings become a short topic summary. Great for meetings. ✓ Sentiment analysis: detect the tone of the conversation (positive, negative or neutral). ✓ Message scheduling 📅 (Pro): schedule an individual message to a contact for the right moment, with variables like {{name}} and {{date}}. It uses WhatsApp's official chat (click-to-chat) — not bulk sending — with built-in safety limits (spacing between sends, timing variation, and hourly/daily caps). Free: up to 3 scheduled messages/day. ✓ Interface in 3 languages: use ZapVox in Portuguese, English or Spanish — it detects your browser language and you can switch anytime from the popup. ✓ Quick review: words transcribed with lower confidence are highlighted, so you only double-check what matters. ✓ Instant search: press Ctrl+K and find any past transcription in seconds. ✓ Reminders 🔔: create one straight from an audio or from the panel. Notification at the scheduled time. ✓ Privacy Mode 🔒: blurs contact names, profile photos and message content. Hover reveals individual items. Customizable shortcut (Ctrl+Shift+0 · Mac: Cmd+Shift+0). ✓ Screen Lock 🔐: protects the screen with a local PIN and auto-locks after inactivity. PRIVACY Privacy Mode, Screen Lock and reminders run in your browser. On Pro you can optionally sync reminders and scheduled messages across your own devices. Cloud transcription is optional and requires login. With BYOK mode you process audio with your own AI key, without going through our servers.
