“Free tools transcribe fine.”
Free tools get you 80% there. The last 20% (punctuation, capitalization, natural line breaks, speaker labels) is what separates amateur subtitles from professional ones. Fluen handles all of it automatically.
“I can fix errors manually.”
You could. But on a 30-minute video, that means reviewing ~400 subtitles. With 99.4% accuracy and smart segmentation, Fluen cuts your manual review time by 90%.
