Voice profiles
A voice profile biases every polish towards writing you already published, instead of towards a generic neutral.
What it is
A profile is built from samples you upload: sentence length, contraction rate, how often you hedge, which connectives you actually use. It changes which replacements are preferred. It never changes which categories are detected.
Build one
Three to ten pieces of your own writing, 500 words or more each. Fewer than three and the profile stays close to neutral. More than ten changes very little.
Use one
Pass the returned id as voice on any polish. A profile and a tone preset combine: the tone sets the register, the profile sets the habits.
Pro and Team only
Free keys can read profiles but not create them. Samples are never used to train a shared model.
