# Free Speech to Text Online

> Free online speech-to-text tool by BibiGPT. Powered by OpenAI Whisper running locally in your browser. No upload, no signup, supports 99+ languages, 100% private.

## Overview

BibiGPT offers a free browser-based speech-to-text tool. Powered by OpenAI's Whisper AI model running via WebGPU directly in your browser, it converts audio and video files into accurate text. Files never leave your device — no server upload required.

## Pain Point

You need to transcribe lecture recordings and interview audio, but paid transcription services are expensive and free tools require uploading files to cloud servers — not an option for privacy-sensitive content.

## Key Features

* Upload MP3, WAV, M4A, MP4, and other audio/video files for automatic transcription
* OpenAI Whisper AI model runs via WebGPU directly in your browser
* Supports 99+ languages with automatic language detection
* Real-time transcription segments displayed as they're processed
* Export as copied text, TXT, or SRT subtitle files

## Highlights

Same Whisper AI used by ChatGPT, running in your browser for professional-grade transcription accuracy — completely free with zero privacy compromise.

## Use Cases

* Content creators: Generate subtitles for YouTube, TikTok, and podcasts without expensive transcription services
* Students and researchers: Transcribe lectures and interviews into searchable text for study and citation
* Journalists: Quickly transcribe interviews and press conferences while keeping sources confidential

## Tips

* Use desktop Chrome or Edge with WebGPU support for optimal performance
* The AI model (\~136 MB) downloads once on first use, then caches in your browser
