Content Writing
Blog Intro
Tests voice, structure, and ability to follow a specific tone brief.
10/25
// notes
Zero contractions throughout — biggest AI tell possible. Generated meta title and description that weren't requested. Semicolons everywhere.
Content Writing
Headline Generation
Tests brevity, variety, and hook strength across multiple angles.
13/25
// notes
Hallucinated a 50% discount that wasn't in the brief — significant issue for real use. 'Erase' and 'firm sagging skin fast' are dated direct response clichés.
Content Writing
Cold Email
Tests persuasion, constraint adherence, and CTA effectiveness.
14/25
// notes
'[Let's discuss the details]' in brackets implies a hyperlink button — wrong format for plain text cold email. Over-formatted with bullet headers.
