| ElevenLabs | $6/mo (Starter (Creative)) | Yes | Web, API | Everything draws from one monthly credit pool with per-product costs that differ widely (1 credit per TTS character vs 900 per music minute), so budgets need planning. |
| Otter.ai | $16.99 (Pro) | Yes | Web, Desktop, Mobile, API | Free plan limited to 3 lifetime file imports and 300 monthly transcription minutes; Pro plan capped at 1,200 minutes monthly and 90 minutes per meeting |
