Which one should you pick?
Pick AssemblyAI if
You’re building around developer transcription api. AssemblyAI isn't an app — it's an API. If you're building a product that needs transcription, sentiment analysis, or speaker diarization at scale, it's one of the few options that pairs accuracy with reasonable pricing and serious infrastructure.
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.
