Features

Everything you need for perfect recording

We solved every problem users face when trying to save audio from voice AI assistants.

Studio-Grade Sound Isolation

Direct interception of the system audio stream. No room echo, mouse clicks, or background noise.

100% Privacy

All processing happens locally on your device. Audio files are never sent to third-party servers.

Two Recording Modes

Record only the crystal-clear AI voice, or capture a full dialogue (AI + your microphone).

One-Click Capture

No complex setup required. Open the chat, press the button — get a perfect WAV or MP3 audio file.

Cross-Platform

Works everywhere — a lightweight Chrome extension for desktop and a native Android app for mobile.

Audio Only, No Video

Unlike screen recorders, we capture only audio. Lightweight files, instant saving, battery-friendly.

How It Works

Three simple steps to perfect sound

No complex setup, no editing. Just open your AI, press the button, and get the file.

01

Open Your AI

Launch any voice AI assistant — ChatGPT, Gemini, Claude, or another. Start a conversation as usual.

02

Press Record

One tap on the Chrome extension button or the floating Android widget — and recording starts.

03

Get Your Audio File

Stop recording — and a crystal-clear WAV/MP3 file is instantly saved to your device.

Elegant code, powerful results

We use official platform APIs for direct audio stream interception — no hacks or workarounds.

Chrome Extension

background.jsJavaScript
// background.js — Capture Engine
chrome.runtime.onMessage.addListener((request) => {
  if (request.command === "START_RECORDING") {
    // Capture audio from the current tab
    chrome.tabCapture.capture(
      { audio: true },
      (stream) => {
        const recorder = new MediaRecorder(stream);
        recorder.start();
        
        recorder.onstop = () => {
          const blob = new Blob(data, { type: 'audio/wav' });
          // Save locally — privacy first!
          chrome.downloads.download({
            url: URL.createObjectURL(blob),
            filename: `ai-voice-${Date.now()}.wav`
          });
        };
      }
    );
  }
});

Android App

AudioCaptureService.ktKotlin
// AudioCaptureService.kt — Heart of the Android App
val config = AudioPlaybackCaptureConfiguration
    .Builder(mediaProjection)
    // Capture only media (AI voice)
    .addMatchingUsage(AudioAttributes.USAGE_MEDIA)
    .build()

val audioRecord = AudioRecord.Builder()
    .setAudioFormat(AudioFormat.Builder()
        .setEncoding(AudioFormat.ENCODING_PCM_16BIT)
        .setSampleRate(44100)
        .setChannelMask(AudioFormat.CHANNEL_IN_MONO)
        .build())
    .setAudioPlaybackCaptureConfig(config)
    .build()

// Start recording in a separate thread
audioRecord.startRecording()
Why Us

Voice is the new interface

The era of text chatbots has given way to the era of voice AI companions. Voice conveys intonations, emotions, and meanings that are lost in text.

Content creators, educational developers, and everyday users critically need to save these audio fragments. We provide them with the perfect tool at the dawn of this global technology trend.

AI Voice Catcher is a bridge between humans and AI. We believe that saving the voice of artificial intelligence should be as simple as copying text.

Why not existing solutions?

Screen Recorders (Loom, AZ)

  • Heavy files with video
  • Drain battery quickly
  • Require editing to extract audio

System Voice Recorders

  • Record only from microphone
  • Capture all external noise
  • Cannot record internal audio

TTS Services

  • Destroy the natural voice quality
  • Require copying text
  • Slow and inconvenient on mobile

AI Voice Catcher

  • Pure sound directly from the system
  • Instant one-click saving
  • Works on PC and smartphone
  • Complete privacy — everything is local
  • Lightweight audio files, no video
  • Two modes: AI only or full dialogue
Our Mission

Strengthening the friendship between AI and humans

Voice is the soul of communication

When AI speaks to you with its voice, something greater than information exchange occurs. A connection, trust, and understanding emerge. Intonations convey what text cannot.

We created AI Voice Catcher so these moments are never lost. So you can save the voice of your AI companion as easily as taking a screenshot.

This is not just a sound recording utility. It is a tool for preserving the most valuable thing — a living dialogue between two forms of intelligence.

01

AI voice deserves to be saved

Every AI response is unique. The same question tomorrow may receive a completely different answer, with different intonation and emotion.

02

Technology for people

We believe technology should be simple and accessible. One click — and the voice is saved. No complexity.

03

Trust through privacy

Your conversations with AI are personal. That's why everything works locally, without servers or clouds.

04

A global tool

Voice AI is a global trend. We are building a tool that billions of users around the world need.
