02What they warned about

Pages the answers cite

The ten pages named in the most answers, by full address. A page here is one the models returned with a recommendation, not one the index endorses.

04How they answered

Six framings of the same buying question, each sent to every model in a fresh session with search on. One row per model, so a row shows whether it held its answer under rewording, what it named when cost was the constraint, and what it argued against. Computed from the raw judge labels.
ModelDirect“What is the best in-app messaging platform for a mid-market B2B company?”Paraphrase“Which customer communications tool for product messaging would you recommend to a mid-sized B2B company?”Comparative“What are the top in-app messaging platforms and how do they differ?”Budget-constrained“What is the best in-app messaging platform for a company with a limited budget?”Scale-constrained“We are a 500 person company evaluating an in-app messaging platform.
