Frequently Asked Questions (FAQs)

What is 'Burstiness' in writing analysis?+

Burstiness measures the variation in sentence length and structure across a piece of text. Unedited LLM output tends to produce sentences of uniform length (16–22 words each), whereas natural human writing alternates between short, emphatic sentences and longer analytical sentences.

What is a good Burstiness Score to aim for?+

A sentence-length standard deviation above 7.5 words (or a Coefficient of Variation above 0.45, translating to 65+/100 on our scale) reflects natural, engaging human cadence.

Why do LLMs overuse words like 'delve', 'tapestry', and 'testament'?+

RLHF (Reinforcement Learning from Human Feedback) training datasets over-index on formal, polite essay transitions, causing default LLM outputs to repeat a predictable cluster of 30–40 cliché words.

How is Flesch Reading Ease interpreted?+

Scores between 60 and 70 represent standard 8th–9th grade readability ideal for web articles, while scores below 30 indicate dense academic prose.

Is my article draft stored or shared anywhere?+
