About This Tool

This tool converts audio or video inputs into time-stamped subtitle files, enabling efficient captioning workflows for media teams and educators. It uses speech-to-text models to transcribe speech, then aligns text to precise timecodes and exports to SRT or VTT formats. The system supports multiple languages, optional speaker labeling, and punctuation restoration for readability. It is designed for batch processing, quality review, and integration into publishing pipelines. Benefits include faster caption creation, improved accessibility, and easier indexing for search engines. Typical use cases include video production, e-learning, marketing clips, and live-event archives. Core differentiators are high language coverage, adjustable transcription quality, and flexible export options that fit content platforms and CMSs.
The tool emphasizes reliability and scalability, handling long-form content and noisy audio with configurable noise suppression. It provides clear confidence markers for segments requiring human review and offers glossary support to improve domain-specific vocabulary. By exporting standard formats, teams can publish captions across platforms with consistent timing and punctuation, boosting accessibility and engagement.

  1. Provide audio or video input and select the primary language.
  2. Choose subtitle format (SRT or VTT) and optional glossary or diarization.
  3. Run transcription to generate time-stamped captions.
  4. Review confidence markers and adjust punctuation/settings as needed.
