Review each bot’s usable knowledge sources, source limit, and settings that determine who may access that knowledge. These fields show how a tool may fit a support or internal-information workflow.
Ask how source access is managed before adding private material.

Citations in an answer let readers follow it back to the material supporting the response. Compare whether citations are listed and how they appear in the product’s published details.
When users ask questions in multiple languages, check the languages the tool supports.
Check code and hosting terms
