How the AI Transcription Works
Upload Your File
Select or drag any audio or video file. The file is read locally by your browser — never uploaded anywhere.
Whisper AI Decodes Speech
The OpenAI Whisper model runs via WebAssembly in your browser. It automatically detects speech and converts it to text.
Download Transcript
Copy the transcript, download it as a .TXT file, or export SRT subtitles with timestamps for video captioning.
Frequently Asked Questions
Is my audio or video file uploaded to a server?
No. Transcription runs 100% client-side in your web browser using WebAssembly. Your audio and video files never leave your device.
Which languages are supported?
OpenAI Whisper supports over 98 languages including English, Hindi, Gujarati, Spanish, French, German, Portuguese, Russian, Japanese, Chinese, Arabic, Korean and more.
What audio and video formats are supported?
Supported formats include MP3, WAV, OGG, FLAC, AAC, M4A, MP4, WebM, MOV, AVI, MKV — any format your browser can natively decode.
Can I download SRT subtitle files?
Yes. After transcription completes, you can download the transcript as a plain .TXT file or as a .SRT subtitle file with precise timestamps.
Why does the first transcription take time?
The Whisper model weights are downloaded from HuggingFace CDN on first use (77–488 MB depending on model). This is a one-time download cached in your browser. Subsequent transcriptions using the same model are instant.
