OpenAI Whisper AI Transcription - Free & Local

Extracting spoken dialogue from videos or podcasts usually requires expensive software subscriptions or sending your private recordings to third-party cloud APIs. VideoBox introduces a revolutionary free speech-to-text tool powered by OpenAI's Whisper model, running 100% locally in your browser. Transcribe interviews, lectures, and meetings securely without ever uploading your files.

How Our Local Transcription Works

  • Select an AI Model: On your first use, your browser downloads a compact version of the Whisper AI model (cached for future use). Choose between Tiny for maximum speed, or Small for highest accuracy.
  • Drop your media: Feed in any MP4 video or MP3 audio file. With local processing, you can transcribe hour-long lectures without worrying about arbitrary upload limits or API costs.
  • Export Subtitles: The AI engine will analyze the audio offline. In minutes, you can copy the plain text transcript, download a TXT file, or export an SRT file perfectly timed for video subtitles.

Why Local Speech Recognition is Essential for Privacy

Audio recordings often contain highly sensitive personal or corporate information. By utilizing WebAssembly and client-side machine learning, VideoBox guarantees that your voice data remains strictly on your own hardware. You get enterprise-grade transcription capabilities completely free, with zero risk of data leaks, making it the perfect tool for journalists, students, and professionals handling confidential media.
