Frequently Asked Questions​

Can I add voice notes without a DevOps team?​

Yes! VocaFuse is designed for small teams and solo developers. You don't need to manage infrastructure, storage, queues, or scaling. Just integrate the SDK and receive transcriptions via webhook—no DevOps expertise required.

How is this different from using OpenAI Whisper directly?​

OpenAI Whisper handles transcription, but you still need to build: secure file upload, audio storage, webhook delivery with retries, multi-tenant authentication, and monitoring. VocaFuse provides the complete production infrastructure around Whisper.

Do I need to handle audio file storage?​

No. VocaFuse handles secure upload, storage, and cleanup automatically. You receive transcriptions via webhook and can optionally retrieve audio files through the API—no S3 buckets or storage management needed.
