Frequently Asked Questions
Quick answers to common questions about RepurposeAPI
How does it work?
Upload your audio or video file via our API, and we'll process it using AI (Whisper for transcription, GPT-4 for content generation). You'll get back transcripts, chapters, summaries, blog posts, and more—all structured and ready to use.
What formats do you support?
We support MP3, MP4, WAV, M4A, and FLAC files up to 50MB. Works with podcasts, interviews, webinars, YouTube videos, and any audio content you want to repurpose.
Is it really free?
Yes! Every account gets 30 minutes of free processing per month. Perfect for testing or processing a few episodes. No credit card required to get started. Paid plans available for higher usage.
How accurate is the transcription?
We use OpenAI's Whisper model, which typically achieves 95%+ accuracy for clear audio. Accuracy depends on audio quality, accents, and background noise. You can review and edit transcripts before generating other content.
Can I use this commercially?
Absolutely! All plans (including free) allow commercial use. You own all the generated content—transcripts, blogs, captions—and can publish, sell, or use them however you like.
How long does processing take?
Transcription takes about 1.5-2x the audio length (30-min podcast = ~45-60 min). AI tasks like summaries and blogs add 1-3 minutes each. You'll receive results via polling or webhooks (coming soon).
