Omni's house style avoids em dashes, one of the clearest tells of AI-written text, so output reads more human by default. Tone actions and model choice close the rest of the gap.
Tone actions reshape a draft without changing its meaning. Direct and Casual read as human on LinkedIn, where AI-written text is most obvious and least forgiven. One click each.
Select text anywhere and run rewrite, shorten, or expand. In editable fields such as email drafts the result can be inserted straight back into the field; elsewhere it opens in the panel.
LinkedIn aggressively blocks injected extensions, so in-page features like selection toolbars can silently not appear. It is the site blocking Omni, not a bug. Use the toolbar and palette.
