Lunaver Studio
AI book studio, your API keys
Free · In‑App Purchases
Free: write, dictate, braille and audiobook. Covers: Google retired its previous image model; covers work with an OpenAI key until Oct 23, and an update is coming.
THE BOOK STUDIO YOU CAN HEAR
Lunaver Studio is a writing studio for whole books, built from day one for VoiceOver, keyboard and voice – by an author who is losing his own eyesight. From idea to outline, chapters and editing all the way to the finished book: you write or dictate, the AI is your editing desk, and you remain the author.
WRITE AND PUBLISH FOR FREE
The studio itself costs nothing: an editor with dictation and voice control, a Story Bible for characters and places, multi-stage quality review, Lumi the assistant – and the outputs blind and low-vision readers need most: braille (BRF and Unicode braille), DAISY, audiobook, plain text and Markdown. No account, no watermark, no time limit.
STUDIO COMPLETE – BUY ONCE, NO SUBSCRIPTION
If you also want your book as an eBook (EPUB), print PDF, DOCX or as a shop package for sale, “Studio Complete” unlocks every export format with a single purchase – on Mac, iPhone and iPad at once (Universal Purchase). No subscription, no credits, no hidden costs. If you bought Lunaver Studio earlier as a paid app, you keep every export without any additional purchase.
YOUR KEYS, YOUR MODELS
You can bring your own API keys, but you don’t have to. Claude and Gemini for writing, OpenAI and Perplexity for research, ElevenLabs for natural audiobook voices: copy the key on the provider’s page, paste it into Lunaver – or just say “Paste my Claude key.” Keys live in your device’s keychain. Lunaver runs no AI backend of its own, never receives your content and never bills AI usage; optional providers charge you directly under your existing agreement with them.
USABLE WITHOUT ANY KEY
On iPhone and iPad with Apple Intelligence, Apple’s on-device AI writes and plans right on your device, private, no cloud: iPhone 15 Pro and iPhone 16 or later, iPad mini (A17 Pro) and iPad models with M1 or later, with Apple Intelligence turned on and a supported language. On older devices the app writes with your own cloud key. Manual writing, dictation, the Story Bible and every export work without any AI.
A REAL WRITING STUDIO, NOT A VENDING MACHINE
Instead of push-button mass output you get a tool for authors: write a chapter, have it read aloud, interrupt, correct, keep reading. Quality loops review and improve every chapter, the Story Bible keeps characters, places and threads consistent, and Lumi guides you through every step by voice.
GERMAN AND ENGLISH, BOTH FIRST-CLASS
Lunaver Studio is built bilingual: an English and German interface with spoken announcements in the core flows, plus proper German typography for print-ready output.
ACCESSIBLE FROM THE GROUND UP
Labeled controls, audible status messages and a clear reading order accompany every step from the first sentence to the export. Everything described here was built with VoiceOver and tested with VoiceOver.
A NOTE ON LONGER AI RUNS
Longer cloud generations work best with the display on; iOS does not continue them in the background. For hours-long book production and audiobook export of whole books, Lunaver Studio for Mac is the first choice; iPhone and iPad are ideal for ideas, dictation, chapter work and everything on the go. One purchase covers all three.
WHO IS IT FOR?
For authors and self-publishers who want more than a rough draft: control over every chapter, verifiable quality and a manuscript that belongs to no one but you. And for everyone who wants to hear their book, read it in braille or write without looking at the screen.
HONEST AND UPFRONT
Your manuscript stays on your device; content is sent to a provider only when you start a cloud action yourself and have explicitly approved that provider. No tracking, no analytics SDKs, no Lunaver AI backend. Dictation, camera and photos require the corresponding system permissions.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Lunaver Studio is now free: Braille, DAISY, audiobook, text and Markdown without any purchase. eBook, print PDF, DOCX and shop package unlock once with “Studio Complete” – no subscription, valid on iPhone, iPad and Mac. If you bought the paid app, you keep every export.
BUY WITHOUT SURPRISES: Price straight from the App Store, audibly distinct outcomes (cancelled, approval pending, no connection, error), “Redeem code” for offer codes. Launching without internet never takes an unlock away.
GETTING STARTED WITH VOICEOVER: Your book idea stays saved – after “Later” or a restart. The button is now called “Later” for VoiceOver too. No more duplicate start announcements.
ANNOUNCEMENTS THAT CAN WAIT: Status messages speak only when Lunaver is back in front, paced by sentence length.
