Models have a default voice, and it rarely matches yours. Style control means telling the model how to write, not just what to write: the tone, the reading level, sentence length, words to use or avoid, and the structure of the result.
A short style guide in the prompt, with an example and a check of the output against its rules, works better than adjectives like “professional” or “friendly”. For finer control, directional stimulus prompting adds hints such as keywords the answer should include. These guides cover writing a style guide prompt, keeping style and density consistent across long documents, and steering output with hints.
The library lists all guides with filters for topic, level, category and reading time.
