Which one should you pick?
Pick NVIDIA NeMo if
You’re building around ml engineers training custom asr, including parakeet and canary models.. NeMo is the toolkit behind Parakeet, currently near the top of Hugging Face's open ASR leaderboard. A heavy framework with PyTorch Lightning under the hood, suited to teams comfortable training their own models.
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.
