Paste your OpenAI API key below (get one at platform.openai.com → API keys). It is stored only in this browser, and only ever sent straight to OpenAI to transcribe your audio — nowhere else.
Pick your sermon audio file. Files up to 25 MB go straight through; bigger ones are split into pieces automatically and joined back together.
Press Transcribe and wait. A one-hour sermon usually takes a few minutes.
Copy the transcript or download it as a text file.
About cost: transcription is not free — OpenAI charges about $0.36 per hour of audio (a few cents per sermon), billed to whatever payment method is on your OpenAI account. Your key, your account, your bill.
