Which one should you pick?
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.
Pick Vosk if
You’re building around developers building offline or embedded apps who need an open-source asr with mature bindings.. Vosk is a long-standing open-source toolkit built on Kaldi, with bindings for Python, Node, Android, iOS, and even Raspberry Pi. Accuracy lags Whisper but the small models run on devices with under 100MB of RAM.
