Which one should you pick?
Pick OpenAI Whisper API if
You’re building around developers wanting raw transcription. Raw Whisper through OpenAI is still one of the cheapest ways to get high-quality transcription — $0.006/min for Whisper or gpt-4o-transcribe, and $0.
Pick Otter.ai if
You’re building around meeting-heavy teams. Otter pivoted hard into meetings and away from straight transcription, which makes it great if you live in Zoom/Meet/Teams and want auto-summaries plus action items — and slightly awkward as a pure podcast transcription tool. The free plan caps you at 300 minutes and 30 minutes per file.
