OpenAI's hosted transcription API is a strong way to turn audio into text. RealtimeVoiceKIT is for teams that want that Whisper API workflow in production without stitching together file storage, retries, status polling, transcript review, subtitles, translation, and billing from scratch. We are an independent product, not an official OpenAI site, built for practical speech-to-text workflows around OpenAI transcription.

Frequently asked questions
Is RealtimeVoiceKIT the official OpenAI Whisper API?
No. RealtimeVoiceKIT is an independent transcription product. It is built for teams that want an OpenAI Whisper API workflow plus a complete app, exports, webhooks, translation, and account management.
Why not call OpenAI's transcription API directly?
Calling the raw API is a good choice when you only need a transcript string. RealtimeVoiceKIT helps when you also need uploads, storage, retries, status pages, subtitles, sharing, translation, summaries, and billing-ready developer API keys.
Can I export subtitles from Whisper API transcripts?
Yes. RealtimeVoiceKIT exports transcripts as plain text, SRT, and VTT so you can use the result in video editors, players, and publishing workflows.
Can I start free?
Yes. The Free plan includes 10 transcription minutes every month, no credit card required.
