AI Prompts for Claude for Brand Voice

Read these three to five pieces of writing that represent our brand at its best: [PASTE SAMPLES]. Identify the voice patterns that appear consistently across all of them. I am looking for: sentence length and rhythm, level of formality, vocabulary range, how we handle humor or personality, what we avoid saying, and the overall feeling the writing creates. Give me a structured breakdown, not a vague description.

Our brand voice is: [PASTE GUIDE]. Read this batch of content pieces: [PASTE CONTENT].

Here are 10 pieces of content from our brand over the past 12 months: [PASTE SAMPLES OR DESCRIBE].

Our brand voice is described as: [PASTE GUIDE]. Create a scoring rubric that any editor on our team can use to evaluate whether a piece of content matches our voice.
