Your book. Your voice. Lunaver Studio is a writing app you can run with your ears. You speak, it writes. You hear your chapter before you change it. It exists because its developer is losing his sight and no writing tool was made for ears. Today it is for everyone who would rather speak and listen than type and read. Our mission Writing should be closed to no one. That is why writing, listening, audiobook, Braille and DAISY stay free in Lunaver Studio. We commit to passing on 25% of our net revenue to organizations for blind and visually impaired people and to reporting on it on our website. Write by voice, keyboard or with Lumi Dictate or type, or let Lumi, your AI assistant, draft a chapter. Lumi plans with you, knows your chapters and answers questions about your text. Every chapter can be read aloud so you hear how it sounds. Voice commands and spoken feedback guide you through the app. Built for VoiceOver, not patched on Controls, dialogs and messages are labeled for VoiceOver. Dark interface, high contrast, reduced motion and Voice Control are supported. If something does not work, we want to know: write to us through the support page. Characters and plot at hand Collect characters, places, relationships and details in the Story Bible. While planning and revising, everything is within reach, and Lumi knows it too. Revise with focus Check repeated words, compare every proposed change with the original and decide one by one what to accept. Version history keeps every change traceable. Share your book Free, always: audiobook with Apple voices, Braille (BRF and Unicode), DAISY, plain text and Markdown. To publish: EPUB, print PDF, Word (DOCX) and the shop package are unlocked by Studio Complete, a one-time purchase for good. No subscription: nothing renews on its own, and what you bought stays yours. The purchase dialog shows the price. Before you buy, you can export the beginning of your first chapter as a marked sample to check the quality. Support If you want to support further development, you will find voluntary contributions under β€œSupport”: small, medium, large. Contributions add up; once they reach the price of Studio Complete, it is unlocked, exactly as with the one-time purchase. No subscription, nothing expires. For schools, training centers and organizations for the blind Schools for the blind, vocational training centers and associations can contact us through the support page. Your text stays with you Apple Intelligence supports selected tasks on compatible devices; on the Mac, local AI models are available in addition, depending on device and system. If you wish, connect your own cloud provider with your own API key; the key is stored in the keychain, use requires your consent and may incur costs with the provider. The app uses cloud providers only if you set them up yourself. For Mac, iPhone and iPad Lunaver Studio is available for Mac, iPhone and iPad. Interface, generated books and audiobooks in English and German. Lunaver Studio is built by a single developer in Herrsching am Ammersee, Germany. Every piece of feedback is read.
