Methodology

This comparison is based on an analysis of user reviews collected from major platforms including the App Store and Google Play. These reviews were processed and labeled by a large language model using a predefined dimension lexicon, allowing for systematic categorization by:

• dimension (specific feature areas like response speed and text quality)
• sentiment (positive or negative assessment)
• keywords (user-stated terms and phrases)

It's important to note that different tools may have different review volumes, which could influence the balance of feedback. Dimension-level analysis includes both quantitative metrics (positive/negative counts) and qualitative insights (keyword trends), providing a comprehensive view of user experiences across key performance areas.
