Smarter, More Accurate YouTube Subtitles

YouTube's built-in captions get the words roughly right. Fluen gets the punctuation, segmentation, and formatting right too.

Frequently Asked Questions

How do I add subtitles to my YouTube video?

Upload your video file to Fluen (or import it from Google Drive or Dropbox), and our AI generates accurate captions automatically. Review them in the built-in editor, then export as an SRT file. In YouTube Studio, go to your video's Subtitles section, click "Add language," then "Upload file" and select your SRT. Your professional captions will appear exactly as you reviewed them.

Are Fluen subtitles better than YouTube's auto-captions?

Yes, significantly. YouTube's auto-captions miss punctuation, break lines mid-word, ignore capitalization, and produce long, unreadable subtitle blocks. Fluen generates broadcast-quality captions with proper punctuation, smart segmentation at natural sentence boundaries, correct capitalization, and optional speaker labels. The difference is immediately visible to your viewers.

Can I translate my YouTube captions into other languages?

Absolutely. Once your captions are generated and reviewed, translate them into 50+ languages with Fluen's AI translation engine. Each translation is context-aware and automatically re-segmented for the target language. Export a separate SRT for each language and upload them all to YouTube Studio. Learn more about subtitle translation →

What format does YouTube accept for subtitles?

YouTube accepts SRT (SubRip) and VTT (WebVTT) subtitle files. Fluen exports both formats. SRT is the most widely used and recommended for YouTube uploads. Simply download your SRT from Fluen and upload it in YouTube Studio under your video's Subtitles settings.

How long does it take to generate subtitles?

Most files are processed in minutes. A typical 10-minute YouTube video takes about 1–2 minutes to transcribe. Longer videos (60+ minutes) take 3–5 minutes. Processing time depends on file length, audio quality, and the AI engine selected. You'll be notified as soon as your captions are ready.

Is there a free plan?

Yes. The free plan lets you caption and translate 3 files (up to 90 minutes each) and review the results in the editor, no credit card required. Downloading subtitles (including the SRT for YouTube), exporting video and importing your own SRT files require a paid plan. See pricing →
