Every feature, every update to your licence, yours forever. Bring your own AI keys.
Checkout securely with StripePayments processed by Stripe. Your key is emailed after payment. Digital licence: no change-of-mind refunds, but genuine faults are always looked at. See our refund policy.
Yes. Creator Studio is A$199 AUD, paid once. There is no subscription, and every feature is included permanently.
Check your spam or junk folder first, and search for "licences@jhsoftware.au". If it is not there after a few minutes, use "Contact support" and send us the email address you paid with. We will resend your key.
Open the app, click the Free Mode badge, paste the key from your email and press Activate. Your key works on all of your own devices. To move your books and audio chapters between computers, either connect a USB flash drive using "USB / Folder" in the top bar or use Save Project Backup (.narraitor) in the Tools tab.
You can use the editor, live previews, layouts, cover calculator, barcodes and free voices, plus 5 watermark-free PDF or EPUB exports every calendar month (and unlimited watermarked draft proofs). Creator Studio unlocks unlimited clean exports forever, ACX audio mastering, the continuity scanner and the audiobook bundle.
No. NarrAItor runs in your browser. If you want it in its own window, use your browser's Install option (in Chrome or Edge, the icon in the address bar). After the first load it works offline.
Any modern Chrome, Edge, Safari or Firefox browser on Windows, macOS or Linux. It is designed for a desktop or laptop. Chrome and Edge give the best results for PDF export and neural voices.
Yes, after the first load. Writing, layout, covers, barcodes, EPUB and PDF export all work offline. AI features need an internet connection and your own API key, and the free Kokoro voices need one for the first-time model download.
On your own device, never on our servers. By default, drafts and snapshots are saved in your browser storage, and you can also click "USB / Folder" in the top bar to live-sync your project, revisions, exports and audio chapters directly to a USB flash drive or local folder on your computer. Because clearing browser cache/site data or using Private/Incognito mode erases browser-only storage, we recommend connecting a USB/local folder or clicking Save Project Backup (.narraitor) regularly.
Yes. Click "USB / Folder" in the top bar (or in the Tools tab) and pick a folder on your USB flash drive or computer. In Chrome, Edge, Brave and Opera, NarrAItor creates an organised workspace on that drive and automatically live-saves your full project (project.narraitor), live manuscript (manuscript.md), timestamped revision snapshots (Revisions/), exported books (Exports/) and generated or recorded audio chapters (Audio_Chapters/). Unplug the USB, plug it into another computer, select the folder and your entire book and audio chapters load right back up.
Your manuscript and up to 25 Revision Vault snapshots typically use only 50 KB to 2 MB, and your settings and licence key use under 20 KB. If you use the free Kokoro-82M neural voices, the AI voice model is cached after its first download (~86–92 MB in standard mode, or ~325 MB with WebGPU hardware acceleration). Open the Tools tab and use the in-app Device Storage & Cache Manager to see a live storage breakdown, clear the neural voice model cache in one click, clear old snapshots, or reset studio data while keeping your activated licence key safe.
Click Download / Export Manuscript in the Source tab (or use the quick-export buttons) to save your book as a Print-Ready or Ebook PDF (.pdf), reflowable eBook (.epub), formatted Microsoft Word document (.doc), clean Plain Text (.txt), Markdown source (.md), or a complete Project Backup (.narraitor). When a USB or local workspace folder is connected, exported files are also saved automatically into its Exports/ folder.
Only for the optional AI features. Add your own Gemini, ElevenLabs or OpenAI key in the AI Keys tab. Keys stay in your browser and are sent only to the provider you choose. The provider bills you directly, not NarrAItor. The editor, layout, covers, barcodes, exports and free voices work without any key.
