About Verspira
Verspira provides on-device speech recognition and subtitle editing within a web browser. It converts audio recordings and video files into editable text without uploading media for automatic speech recognition (ASR). Users can process common formats such as MP4, MOV, WEBM, WAV, MP3, and M4A locally, with transcription results displayed as timeline segments. The platform includes an online subtitle editor for reviewing, adjusting timing, and exporting SRT or VTT files. Optional features include system translation for live captions and a burned-in subtitle export that may send files to servers only when explicitly requested. Accounts are optional and used solely for storing preferences and identity, while speech recognition runs entirely in the browser. The tool supports approximately 99 languages for transcription, with specialized models for Mandarin and other languages.
