How is Onaji different from ChatGPT, Gemini, or Claude?

General-purpose AI tools like ChatGPT, Gemini, and Claude were never shown the writer's prior work. They answer a prompt in the voice they default to, which tends to be the voice of everyone else asking them the same question.

Onaji reads writing samples before it writes anything. Every draft is shaped by a Voice Profile learned from those samples, and every edit the writer makes folds back into that profile. The tool the writer uses next week knows more than the tool they used last week.
