Otter.ai

Best for: Business meetings, interviews, lectures

Pricing:

Real-World Tips

Improve Accuracy

  1. Use a good microphone - Quality input = quality output
  2. Reduce background noise - AI struggles with competing sounds
  3. Speak clearly - Natural pace, distinct words
  4. Use speaker labels - Train the AI on who’s who

Post-Processing

Even the best AI needs human review for:

  • Proper nouns
  • Technical terms
  • Homophones (their/there/they’re)
  • Industry jargon

Budget 15-20% of audio length for review/editing.

Cost Optimization

For occasional use: Otter.ai free (300 min/month)

For regular use: Otter Pro or Happy Scribe subscription

For bulk processing: Whisper locally (free, just your electricity)

Speed Comparison
