Libb is a communication-evaluation brand applying Linguistic Ergonomics, a clinically derived framework, to assess whether people can process AI-generated messages. Founded by Samantha Cocroft, M. S., CCC-SLP, a licensed speech-language pathologist with more than a decade of clinical practice, Libb focuses on the cognitive demands of workplace communication.

Its Cognitive Processability Score examines how ideas and clauses connect, where ambiguity may prompt rereading, and when readers must infer information that has not been stated. Unlike grade-level readability tools, it evaluates the design of the message, not the abilities of its recipients. Libb offers unlimited self-serve evaluations and rewrite suggestions for professionals, as well as founder-led assessments of up to 50 workplace messages with clinical sign-off and tailored recommendations.

Organizations and platforms can also explore enterprise and API services for ongoing, large-scale evaluation. Libb keeps a person in the decision-making loop, processes submitted text transiently, and discards it rather than using it to train models. Its services support communication review and regulatory readiness, without providing legal advice or guaranteeing comprehension
