Features and specs

What each product offers, as listed by its team.

ZapVox 5 features
React 6 features
  • One-click transcription
    A Transcribe button on every WhatsApp Web voice message turns the audio into text right below the bubble, in the language it was recorded in.
  • Translation into 99+ languages
    Translate the transcript of a voice message into any of 99+ languages without leaving the conversation.
  • Summaries of long audios
    Turn a several-minute voice message into a short summary, so you get the point without listening to the whole thing.
  • Tone reading
    Surfaces the sentiment behind the message - useful when the audio is long or the conversation is delicate.
  • Privacy by design
    WhatsApp audio is decrypted inside your own browser and is never stored on our servers.
  • Component-Based Architecture
    React encourages the creation of reusable UI components, which can be leveraged to build complex user interfaces efficiently. This promotes better code organization and separation of concerns.
  • Virtual DOM
    React uses a virtual DOM to optimize and accelerate the process of updating the browser’s DOM, significantly improving application performance.
  • Strong Community and Ecosystem
    React has a large and active community, which means plenty of third-party libraries, tools, and community support are readily available to assist developers.
  • JSX Syntax
    React’s JSX syntax allows developers to write HTML structures within JavaScript code, making the code more readable and easier to debug.
  • Unidirectional Data Flow
    React promotes a unidirectional data flow, which helps maintain the predictability and ease of debugging, especially for larger applications.
  • Extensive Documentation
    React's official documentation is comprehensive, well-organized, and provides numerous examples and tutorials to help developers get started and advance their skills.

Possible disadvantages

  • Steep Learning Curve
    React comes with a steep learning curve for beginners, especially those unfamiliar with JavaScript ES6 and JSX syntax.
  • Boilerplate Code
    Setting up a React project often requires boilerplate code, which can be cumbersome and time-consuming compared to simpler frameworks.
  • Fast-Paced Development
    React and its associated libraries evolve rapidly, necessitating frequent updates and learning new patterns, which can be overwhelming for developers.
  • Complexity in Larger Applications
    As a React application grows in size, managing state and props across components can become complex, sometimes necessitating additional state management libraries like Redux or Context API.
  • SEO Challenges
    React, being a JavaScript library, can present challenges for search engine optimization (SEO) due to Googlebot's limitations in executing JavaScript, although this can be mitigated with server-side rendering (SSR) or static site generation (SSG).

Overall verdict

  • React is generally considered a good choice for developing modern web applications. Its performance, large community, extensive ecosystem, and ease of integration with other technologies make it a compelling option for many developers. However, whether it's the best choice depends on the specific requirements and constraints of your project.

Why this product is good

  • React is a popular JavaScript library for building user interfaces, particularly single-page applications where a dynamic and responsive interface is essential. It is maintained by Facebook and a community of individual developers and companies. React's component-based architecture allows for reusable and self-contained components, making development more efficient and scalable. Features like the Virtual DOM improve performance by updating only the necessary parts of the UI.

Recommended for

  • Developers looking to build interactive user interfaces
  • Projects requiring fast rendering and dynamic updates
  • Applications that will benefit from component reusability and maintainability
  • Teams interested in leveraging a rich ecosystem and community support
  • Projects intending to use React Native for mobile app development in conjunction

Questions & Answers

As answered by people managing ZapVox and React.

Which are the primary technologies used for building your product?

ZapVox's answer

  • A Chrome Manifest V3 extension written in TypeScript, which also runs on Edge and other Chromium browsers
  • Supabase (Postgres plus Edge Functions) as the backend and orchestration layer
  • Speech-to-text and language models from Groq (Whisper), Google Gemini and OpenAI, with the option to bring your own key
  • Audio decryption done locally in the browser with HKDF-SHA256 and AES-256-CBC, the same scheme WhatsApp uses internally
  • Vercel for the website and Stripe for billing

What makes your product unique?

ZapVox's answer

Most transcription tools ask you to leave the conversation: export the audio, upload it somewhere, wait, come back. ZapVox works where the message already is — a Transcribe button sits on every voice message inside WhatsApp Web, and the text appears right under the audio bubble.

It is also more than a transcript. The same click can translate the message into 99+ languages, summarize a long recording, or read the tone behind it — and it works in groups, not just one-to-one chats.

The audio is decrypted inside your own browser before anything leaves it, and it is never stored on our servers.

Why should a person choose your product over its competitors?

ZapVox's answer

It stays inside WhatsApp Web. There is nothing to export and no second tab to open - the button sits on the message itself, and the text lands under the audio bubble.

It also does the whole job from that one click: the transcript, translation into 99+ languages, a summary when the recording runs long, and a read of the tone behind the message. Most alternatives are built for meetings and calls, not for the chat where the audio actually arrives.

The audio is decrypted inside your own browser and is never stored on our servers, which matters when the messages come from clients, patients or your own team.

And the price is friendly: a free tier with no credit card, and Pro from R$ 29.90/month (about US$ 5.50) with a 7-day trial.

How would you describe the primary audience of your product?

ZapVox's answer

People whose work arrives as voice messages and who cannot always stop to listen to them.

In Brazil, where WhatsApp is the default channel for business, that means a lot of sales, support, real estate, legal and healthcare work, plus freelancers and small business owners who get dozens of audios a day and need the content, not the recording.

The second group is anyone working across languages, where translating the message matters as much as reading it, and anyone who is simply on the receiving end of long voice messages from family and friends.

What's the story behind your product?

ZapVox's answer

ZapVox started from a very Brazilian problem. WhatsApp is where work happens here, and a large share of it arrives as voice messages - often several minutes long, often at the worst possible moment: in a meeting, in a noisy place, in the middle of something else.

The tools that existed all asked for the same detour: export the audio, upload it to another service, wait, come back with the text. That is fine once. It is unworkable when it happens twenty times a day.

So the goal was narrow from the start: put the transcript where the conversation already is, one click away, and then make it useful - translated, summarized, with the tone made explicit - without ever storing anyone's audio.
