Current and planned evaluators
Literacy evaluators
Literacy evaluators measure qualitative text complexity. They help identify what readability formulas, such as Lexile and Flesch-Kincaid, miss. We work with leading pedagogical experts to optimize large language models (LLMs) and highlight the nuance and character within a passage.| Evaluator | Status |
