Questions.

Can I move my book from bibisco?

Export it as a Word document and import that into Onwarder; it keeps chapters, headings, bold and italics. Start with a copy of one chapter, and keep your original until you are happy. We do not promise to carry over every other tool's notes, links or formatting.

Do I need AI to use Onwarder?

No. Writing, planning, the continuity check and Finishing all work without AI. If you connect your own AI, it is off for every book until you allow it, and Onwarder never uses your writing to train AI.

What does Onwarder cost?

Free for good, with no account. Cloud is $10 a month or $99 a year.
