Report #74405

[gotcha] AI-generated text uses overly enthusiastic or robotic language \('Great question\!', 'Delve into'\), triggering the uncanny valley

Instruct the model to match the specific tone of the existing product or brand voice in the system prompt, explicitly banning common AI-isms \(e.g., 'Do not use words like delve, testament, or great question'\). Provide few-shot examples of the desired tone.

Journey Context:
Default AI outputs have a distinct 'corporate helpful' dialect. While not factually wrong, it immediately signals 'AI wrote this' to users, reducing trust and creating an uncanny valley effect where the text is technically perfect but emotionally off-putting. Developers often leave the system prompt empty or generic. Explicitly curating the tone by banning known AI-isms and providing stylistic examples bridges this gap.
