Patina

Patina

Write with AI. Still sound like you. Patina marks the lines in your draft that read as machine-written, and tells you why.

An AI draft saves time. It also tends to leave a few sentences behind that nobody you know would say. Patina finds those lines and explains what gives each one away. It never touches your file, so the rewriting, and the voice, stay yours.

It works on writing you did yourself too. If people keep telling you your work sounds like ChatGPT, Patina shows which habits they are hearing, and you decide which to keep.

What it checks

• Tells: the stock phrases and sentence shapes readers have learned to spot.
• Predictability: the sentences a language model would have written first, ranked, so you know where to start.
• The Copybook: each sentence measured against two published novels for its grammar, its words, how it opens and where its commas fall. Lines outside the human range get marked.
• Short lines: a brief, a filter and a cold read for headlines and taglines, so you can see if a stranger understands a line before it goes live.
