Questions? We're Here to Help
Everything you need to know about FluentCap and getting started.
Great question! Instead of paying us a subscription, you connect directly to speech-to-text providers like Deepgram or AssemblyAI using your own API key. This means you pay only for what you use, and you get access to generous free credits ($50-200) that providers offer to new users.
FluentCap itself is completely free — forever. You only pay providers for the actual transcription, which is typically $0.15-0.40 per hour after you use your free credits. Most providers offer $50-200 in free credits, which is hundreds of hours of transcription!
FluentCap can capture: (1) Your microphone for recording your voice, (2) System audio for transcribing anything playing on your computer — movies, YouTube, Zoom calls, podcasts, or (3) Both simultaneously for capturing both sides of a conversation.
FluentCap needs an internet connection to send audio to the speech-to-text provider for processing. However, all your transcripts are stored locally on your computer, so you can access them anytime — even offline.
Thanks to our amazing providers, FluentCap supports 100+ languages for transcription and translation. Deepgram and AssemblyAI both support major world languages including English, Spanish, French, German, Chinese, Japanese, Korean, and many more.
Absolutely. Your privacy is our priority. Audio is only sent to your chosen provider during active transcription. All transcripts are stored locally on your machine — we never see, store, or have access to your data.
Modern AI models achieve remarkable accuracy — typically 95%+ for clear speech. Providers like Deepgram and AssemblyAI have invested years in perfecting their technology, and we're grateful they make it accessible to everyone.
Yes! This is one of our favorite use cases. You can capture system audio from any video source — Netflix, YouTube, local files — and see real-time transcription. You can also enable translation to see subtitles in your preferred language. It's like having a personal translator!
