ZapVox — Communication Assistant for WhatsApp Web

Transcribe, translate and summarize voice messages. Local reminders, privacy mode and screen lock.

🎙️ ZapVox turns voice messages into text, translates, summarizes and adds privacy tools — right inside the conversation. KEY FEATURES ✓ AI transcription: click the ✍️ button next to any audio and read the text in seconds. Recognizes 99+ languages automatically. ✓ Translation into 100+ languages: the translation appears in the bubble itself, below the original. ✓ Smart summary: long recordings become a short topic summary. Great for meetings. ✓ Sentiment analysis: read the tone of the conversation (positive, negative or neutral). ✓ Search what was said: search 90 days of your own transcriptions by subject, speaker or phrase — and jump straight to the message in the chat. Free for everyone. ✓ Glossary (Pro): teach the AI the exact spelling of the terms you use every day — medications, legal jargon, proper names. ✓ Export and daily digest (Pro): export a chat's transcriptions, or get one summary of every audio received during the day. ✓ Message scheduling 📅: schedule a message to a contact for the right moment, with variables like {{name}} and {{date}}. It uses WhatsApp's official click-to-chat — not bulk sending — with safety limits built in: spacing between sends, timing variation, and hourly and daily caps. Free: up to 3 per day. Pro: higher caps, same safety limits. ✓ Interface in 3 languages: Portuguese, English or Spanish — it follows your browser and you can switch anytime. ✓ Quick review: words transcribed with lower confidence are highlighted, so you only double-check what matters. ✓ Reminders 🔔: create one straight from an audio or from the panel. ✓ Privacy Mode 🔒: blurs contact names, photos and message content. Hover reveals one item at a time. Shortcut Ctrl+Shift+0 (Mac: Cmd+Shift+0), customizable. ✓ 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 choose to sync reminders and scheduled messages across your own devices. Cloud transcription is optional and requires login. In BYOK mode the audio goes from your browser straight to your own AI provider, without passing through our servers. PLANS Free: 10 cloud transcriptions per day, up to 15 minutes of audio per day, 3 scheduled messages per day. Pro: 150 cloud operations per day for each feature — transcription, translation, summary and sentiment count separately — and up to 150 minutes of audio per day (fair use). BYOK: connect your own OpenAI or Groq key and the AI features stop counting against ZapVox limits — usage then runs on your own provider quota.
