When to use Otter.ai
Otter excels at live transcription during press conferences, panel discussions, and routine interviews where the content is not confidential. Its automatic speaker identification saves significant editing time in multi-person conversations. The searchable transcript archive makes it easy to find quotes across months of interviews. For on-the-record interviews and public events, Otter's convenience features are genuinely useful and the cloud processing tradeoff is acceptable.
When to use Whisper
Whisper is the right tool whenever the audio involves confidential sources, sensitive story material, or any recording you would not want a third party to access. Whisper processes everything on your local machine. The audio file never leaves your device. OpenAI released Whisper as open-source software under the MIT license, so the code is fully auditable. The large-v3 model handles accents, background noise, and multiple languages well. The tradeoff is setup complexity and the lack of real-time transcription.
The verdict
The deciding factor is confidentiality. If the interview is on-the-record and the content is not sensitive, Otter's real-time features and speaker ID make it the more productive choice. If the audio involves a source who could face consequences if identified, or material that is not yet published, use Whisper. Many journalists use both -- Otter for daily work, Whisper for investigations.
Frequently asked questions
Does Otter.ai store my recordings on their servers?
Yes. Otter.ai processes audio on their cloud servers and stores transcripts in your account. Otter's privacy policy allows them to use your data to improve their services. Audio and transcripts are accessible to Otter employees with appropriate permissions. For interviews involving confidential sources, this is a significant concern.
How accurate is Whisper compared to Otter?
Both produce high-quality transcriptions. Whisper's large model achieves near-human accuracy on English audio. Otter has an advantage with real-time transcription and speaker identification. Whisper's accuracy varies by model size -- the large model is most accurate but slower. For pre-recorded interviews, accuracy is comparable.
Can I run Whisper on my laptop?
Yes. Whisper runs on most modern laptops. The small and medium models work well on machines with 8 GB of RAM. The large model benefits from a GPU or Apple Silicon for reasonable speed. On a MacBook with M-series chips, the large model transcribes roughly at real-time speed. On older machines, use the medium model.
Does Whisper identify different speakers?
Whisper by itself does not perform speaker diarization (identifying who said what). You can combine Whisper with tools like pyannote-audio for speaker identification. Otter handles speaker identification automatically, which is a meaningful advantage for multi-person interviews.
Is there a middle ground between Otter's convenience and Whisper's privacy?
Yes. MacWhisper and other desktop apps wrap the Whisper model in a user-friendly interface while keeping processing local. You get a polished transcription experience without sending audio to the cloud. These apps cost $10-30 as a one-time purchase.
