NarrAItor

​NarrAItor is a powerful, offline-first publishing studio designed to give indie authors complete control over their writing, formatting, and audiobook production. Built as a heavy-duty Progressive Web App (PWA), it runs entirely locally in your browser on PC or Mac. This means no vendor lock-in, no mandatory cloud subscriptions, and absolute privacy for your unpublished manuscripts. You own your workspace from day one. ​At its core, NarrAItor eliminates the headaches of traditional book formatting. The built-in layout engine handles live print-pagination as you type, allowing you to see exactly how your words will look on the printed page in real time. When your manuscript is finished, the studio instantly typesets and exports pristine, print-ready PDFs and flawlessly structured EPUB files for digital distribution, bridging the gap between raw text and a retail-ready book. ​To solve one of the biggest hurdles in self-publishing, NarrAItor features a dynamic cover wrap blueprint engine. The studio automatically calculates your exact KDP spine math based on your real-time page count, ensuring your paperback cover dimensions are precise before you ever upload. ​Beyond print and digital, NarrAItor features a cutting-edge, local neural audiobook studio. Powered by WebGPU and the Kokoro engine, it offers 26 distinct, high-quality AI voices that run entirely on your hardware. You can cast different voices for different characters and master your audio files directly to stringent ACX specifications, bypassing the need for expensive studio time or complicated audio engineering software. ​From the first drafted word to the final published paperback, eBook, and audiobook, NarrAItor provides a single, distraction-free environment. It is the complete, self-contained toolkit for authors who want professional-grade publishing power that stays on their own machine.
