So well-formatted and natural, you'll barely need to edit.
Fine-tune anything in our editor, cut costs, and export in the format you need.
We orchestrate multiple transcription, translation, and AI engines. Our proprietary segmentation technology transforms raw output into natural, well-timed subtitles ready for the screen.
Fluen Studio generates subtitles automatically, applying time codes and line breaks.
Tune the subtitles to perfection by styling the appearance and adding your changes and personal touch.
Export production-ready MP4 files with hardcoded subtitles, subtitle files in SRT, VTT, TTML, SBV, and more, or the text transcript.
Our segmentation engine turns raw transcription into natural, well-paced subtitles by analyzing speech patterns, structure, and timing. We automatically route to the best engine for your content (OpenAI, Deepgram, or AssemblyAI), and you can add domain terms to your Glossary for greater accuracy.
