Onaji is built for professionals who post on a cadence: weekly or more often, to an audience they're building over time. Consultants, founders, researchers, operators, educators, analysts — anyone whose name appears on the post and whose credibility rides on how it sounds.

Onaji is not built for one-off copywriting, brand-voiced marketing where the author is nobody in particular, or high-volume content farming. A writer who doesn't care whether the post sounds like them will find the Voice Profile doing a lot of work for no reward.
