FAQ

What metrics are compared?
Length (characters, words, tokens), readability (average sentence length, average word length), and structure (heading count, list item count, code block count).
How many responses can I compare?
You can compare 2 to 4 responses at the same time. Use the + Add Response button.
How is token count calculated?
Token count uses the word-based heuristic from the built-in tokenizer (~1.3 tokens per word).

Paste 2–4 AI model responses and compare them across multiple metrics: length (characters, words, tokens), readability (sentence length, word length), and structure (headings, lists, code blocks). Best and worst values are highlighted per metric.
