| Fact | AIBookCraft |
|---|---|
| Platforms | Web (aibookcraft.app), iOS (App Store, id6449461895) and Android (Google Play, com.secondearth.bookai). One account works on all three. |
| What you can do | Plan a book from a title or one-line idea, write and edit chapters, draft chapters with AI (Pro), create covers, export PDF or DOCX in the app, play interactive stories, chat with story characters, and read or publish in a public reading community. |
| Languages | Website: English, Korean, Japanese and French; the writing blog is also in Spanish, German and Portuguese. App Store and Google Play listings: English, Korean, Japanese, German, French, Spanish and Portuguese (Brazil). Public stories are published in more than ten languages (Public Story Pulse). |
| Free | Up to three successful AI story-plan previews per UTC day without signing up. A free account saves plans privately and lets you write, edit, publish and print your book. Interactive stories include a daily free allowance of credits. |
| Paid plans (web) | Pro adds AI chapter drafting: US$5.99 per month (charged immediately, no trial) or US$59.99 per year with a 7-day free trial. Prices in USD; your currency, tax, renewal date and final total appear at checkout. See pricing. |
| Paid options (apps) | Subscriptions, credit packs and one-time passes, where offered. The App Store or Google Play shows the price before you buy. Credits bought in the app also work on the web with the same account. |
| Who owns the writing | You keep the ownership rights you have in what you write. Private writing stays private to your account, and SecondEarth does not use it to train third-party general-purpose AI models without separate disclosure and any consent the law requires. Publishing publicly lets AIBookCraft host your work and lets other users read, play, continue and adapt it inside AIBookCraft; you can unpublish at any time. See the AIBookCraft Terms and SecondEarth Terms. |
| Content rules | Ages 13 and up (under 18 with a parent’s or guardian’s permission). An optional adult mode, only for users 18 or older, allows more sensual romance; explicit sexual content is never generated in any mode, and characters in romantic situations are always adults. Scenes, chats, story worlds and public books can be reported in the app, and stories or authors can be blocked. See content rules. |
| AI output | A draft to review and revise. AIBookCraft does not promise publication-ready books, guaranteed originality, publishing acceptance or sales. |
| Company | Made by SecondEarth (세컨드어스), an app studio in Seoul founded by Sunwoo Kim. Operated by SecondEarth AI, Inc., the studio’s US company, which also sells the web plans. Store seller names: “Sunwoo Kim” on the App Store, “SecondEarth” on Google Play. |
