A World of Content Awaits
The world is full of amazing stories. Korean dramas that capture your heart, Japanese anime with breathtaking animation, French cinema that explores the human condition, Spanish series with gripping plots, Bollywood films with incredible music — but language barriers often keep us from experiencing them.
Traditional subtitles have limitations: they might not be available, could be poorly translated, or simply don't exist for the content you want to watch. Fan translations can take months. Official subtitles might never come.
What if you could watch anything, in any language, with real-time subtitles generated instantly?
That's exactly what FluentCap makes possible.
How Real-time Subtitles Work
FluentCap uses advanced speech-to-text technology from providers like Deepgram, AssemblyAI, and Gladia to transcribe audio in real-time.
The Technology Behind It
Here's how the process works:
- Audio Capture — FluentCap captures system audio directly from your computer
- Speech Recognition — Audio is sent to AI providers who transcribe it in milliseconds
- Text Display — Subtitles appear on your screen with minimal delay
- Optional Translation — Transcribed text can be translated to your preferred language
This works with any video source because FluentCap captures at the system audio level — not tied to any specific app.
Supported Languages
Thanks to providers like Deepgram and AssemblyAI, FluentCap supports over 100 languages including:
- East Asian: Japanese, Korean, Mandarin, Cantonese, Vietnamese
- European: Spanish, French, German, Italian, Portuguese, Russian
- South Asian: Hindi, Bengali, Tamil, Telugu, Urdu
- Middle Eastern: Arabic, Hebrew, Persian, Turkish
- And many more...

Best Practices for Watching Foreign Content
Optimize Your Setup
- Start FluentCap before the video — avoid missing the first few seconds
- Position subtitles carefully — don't overlap with hardcoded subs
- Use fullscreen mode — subtitles can overlay on top
- Pause when needed — FluentCap continues transcribing
Audio Quality Tips
For best transcription accuracy:
- Good speakers or headphones — ensures clear audio capture
- Avoid background noise — close other audio-playing apps
- Standard volume — not too quiet, not distorted
Learning While Watching
If you're learning the language:
- Start with content you've already seen in your native language
- Use the transcript to look up unfamiliar words
- Switch between transcription-only and translation mode
- Take notes on phrases you want to remember
