Find Your Optimal Model →Frequently Asked Questions
Can AI-generated marketing copy be used directly?
AI-generated marketing copy works well as a first draft, but should always be reviewed before publishing. Common issues: generic phrasing, repetitive structure, missing brand voice nuances. The best workflow: AI generates 10 variants, human selects the best 2–3 and refines them. For regulated industries (finance, pharma, alcohol), all AI copy must go through compliance review before publication.
How do I maintain brand voice across AI-generated content?
Create a detailed brand voice system prompt that includes: tone descriptors (e.g., "professional but approachable"), example copy from your best-performing content, prohibited words/phrases, target audience persona, and platform-specific formatting rules. Include this as the system message for every API call. Claude models are particularly good at following detailed style guidelines — they maintain voice consistency across 100+ variants better than other models.
