If you run a WhatsApp Business account, you know the scene: the queue keeps growing, a customer sends a 2-minute voice message with the order, the address and three questions in the middle of it — and you can't just stop everything, put on headphones and listen. Worse: by the end of the day nobody remembers exactly what was agreed, because none of it ever became text.
The good news is that you can turn those voice messages into text on the spot, inside the conversation, without leaving your Business account and without changing the way you already work.
Yes, it works with a WhatsApp Business account. The path is WhatsApp Web: your Business account opens normally at web.whatsapp.com, and that's where ZapVox works.
How it works on a Business account
ZapVox is a browser extension (Chrome, Edge and other Chromium-based browsers). It isn't a separate app and it isn't a bot plugged into the official API: it installs in your browser and adds a 🎙️ button to every voice message on WhatsApp Web.
Because a WhatsApp Business account is also accessed through WhatsApp Web (the same web.whatsapp.com, linked to your Business phone), the extension behaves exactly the same: one click on the customer's voice message and the transcription appears right below it, inside the chat.
One accuracy note: ZapVox does not run inside the WhatsApp Business app (neither the phone app nor the desktop program). It runs in the browser, on WhatsApp Web signed in with your Business account. In practice it's the same inbox — just opened in a browser.
Step by step
- Install ZapVox in your browser (Chrome or Edge).
- Open
web.whatsapp.comand link it with your Business phone, the way you already do. - Open any chat with a voice message. Hover over it: the 🎙️ button appears.
- Click it. In a few seconds the text shows up below the audio, inside the chat.
- Copy it, paste it into your system or CRM, or use the summary and translation buttons when the message is long or in another language.
What changes in day-to-day support
| Situation | Listening only | With transcription |
|---|---|---|
| Order by voice (items, quantity, address) | Listen twice to write it down correctly | Text ready to paste into the order |
| Busy support queue | One audio at a time, in real time | Skim several and prioritize |
| Noisy shop or quiet office | You need headphones | Read it on screen, no sound |
| "What exactly did the customer agree to?" | Replay the old voice message | Search the text by keyword |
| Customer sends audio in another language | Hard to handle | Transcribe and translate |
A reading assistant, not a bulk sender
It's worth being explicit about what ZapVox is not: it doesn't send bulk messages, it doesn't automate replies and it doesn't replace the official WhatsApp Business API. It's a reading assistant — it helps you quickly understand what arrived for you, in text, so you can keep replying your own way.
That distinction matters: bulk-sending tools put accounts at risk. Reading a voice message a customer sent you, turned into text for you, is a completely different thing.
What it costs
The free plan gives you 10 transcriptions a day (up to 15 minutes of audio a day), no credit card — enough to test it on real conversations before deciding. ZapVox Pro costs R$ 29.90/month (Brazilian reais) and raises that to 150 transcriptions a day and up to 150 minutes of audio a day, with no watermark and with summary and translation unlocked.
If more than one person on the team uses the same WhatsApp Business account on different computers, there's an Additional computer add-on at R$ 9.90 each.
Who benefits most
Anyone selling through WhatsApp (delivery, retail, resellers), customer support teams, service providers who get briefs by voice, clinics and offices that book appointments through Business, brokers, accountants — any operation where customers would rather talk than type. If your bottleneck is "too many voice messages to listen to", transcription removes most of it.

Install ZapVox on ChromeFrequently asked questions
Does ZapVox work with WhatsApp Business?
Yes — through WhatsApp Web. Your Business account opens normally at web.whatsapp.com and ZapVox, a browser extension, adds a transcription button to every voice message. It does not run inside the WhatsApp Business mobile or desktop app.
Do I need the official WhatsApp Business API?
No. ZapVox doesn't use the official API and doesn't send messages. It only transcribes, summarizes and translates the voice messages that reach you on WhatsApp Web, inside your browser.
Can I transcribe older voice messages in a chat?
Yes, as long as the audio is still available in the WhatsApp Web conversation. Open the chat, find the voice message and click the transcription button.
How many voice messages can I transcribe for free each day?
The free plan gives you 10 transcriptions a day, with up to 15 minutes of audio a day, no credit card. The Pro plan costs R$ 29.90 per month and raises it to 150 transcriptions and 150 minutes of audio a day.
My team uses the same WhatsApp Business account on several computers. Does that work?
It does: each computer needs ZapVox installed in its browser. To use the same Pro subscription on more than one computer there's the Additional computer add-on, at R$ 9.90 each.
