# Travel-brochure and promotional register > Source-anchored research for Travel-brochure and promotional register. Run status: COMPLETED. Parent: [Vague attribution and promotional register in LLM prose](https://llms-explorer.com/tree/ai-isms-attribution-and-register/) · 4 facets · 6 facts · page: https://llms-explorer.com/tree/travel-brochure-and-promotional-register/ ## How it works - Wikipedia's 'Signs of AI writing' guide says LLMs struggle to keep a neutral tone and produce advertisement-like or travel-guide prose even when prompted for an encyclopedic style, both in new text and in rewrites. (low confidence) (verified as of 2026-09-23) — [source](https://en.wikipedia.org/wiki/Wikipedia:Signs_of_AI_writing) ## Problems, failure modes and limitations - The typical failure pattern is on cultural or geographic topics: the text keeps reminding the reader of a subject's importance using flowery description ('nestled within the breathtaking region', 'rich cultural heritage'), which asserts significance without a sourced fact. (low confidence) — [source](https://en.wikipedia.org/wiki/Wikipedia:Signs_of_AI_writing) ## Comparisons and alternatives - Instruction-tuned Llama models overuse specific words relative to base models (e.g. 'nuanced' +8,342%, 'firstly' +4,794%), and a 400-person rating experiment found a significant preference (52.4% vs 47.6%, p<0.01) for high-overuse variants, linking lexical tics to learning from human feedback; this is Llama-only, English scientific text, and the listed words are academic, not brochure vocabulary. (low confidence) — [source](https://arxiv.org/html/2508.01930v1) ## Facts and statements - The Wikipedia watch-word list for promotional register includes: boasts a, vibrant, rich (figurative), profound, enhancing, showcasing, exemplifies, commitment to, natural beauty, nestled, in the heart of, groundbreaking, renowned, featuring, diverse array. (low confidence) (verified as of 2026-09-23) — [source](https://en.wikipedia.org/wiki/Wikipedia:Signs_of_AI_writing) - Word tells are weak evidence: the Wikipedia guide itself says not all promotional writing is AI-generated, and a legal-tech commentator notes they used 'delve' before LLMs existed, so single-word detection is insufficient proof. (medium confidence) — [source](https://en.wikipedia.org/wiki/Wikipedia:Signs_of_AI_writing) - Wikipedia's guide reports older models such as GPT-4 write more blatantly positive text, while newer models are more subtly positive and avoid obvious superlatives like 'the best', so a superlative-only filter under-detects newer output.
