Every 100 words our AI reviews your transcript and assesses if this seems accurate (that it makes sense) and assigns a rating: 👍👍, 👍, 👎, 👎👎
If you're seeing a single or double thumbs down, we suggest you review your transcript for accuracy, and if inaccurate, look into making microphone adjustments to help improve this.
