Questions before you begin.
The short answers to ownership, AI privacy, Premium, and the Free plan.
Where are my novels stored?
In a local folder you choose. You can place that folder inside your own backup or synchronization service.
Is Premium available?
Not yet. HexaQuill Free is the only edition currently available. Premium features are visible as coming-soon previews but remain locked.
Does HexaQuill train AI on my writing?
No. HexaQuill does not operate an AI training service. Text goes to your selected AI provider only when you deliberately use an AI feature.
Do I need Premium to use HexaQuill?
No. The Free plan includes the complete editor, Codex, exports, OpenRouter connection, and up to five editable novels.
