THE STUDIO FOR AMBITIOUS AI-ASSISTED WRITING — WITH YOUR OWN KEYS Lunaver Studio is the AI writing studio for complete books: from idea to outline, chapters, quality review and finished export — print, eBook, audiobook and braille from one source. No Lunaver backend: your manuscript is yours. Content is sent only for a cloud action you start, directly to a provider you explicitly enabled. YOUR KEYS, YOUR MODELS Bring your own API keys and choose for yourself: Claude, Gemini, OpenAI and Perplexity for writing and research — ElevenLabs and Speechify for audiobook voices. Your keys are stored in the macOS Keychain. Lunaver operates no intermediary AI backend, does not receive your cloud content, and does not bill AI usage. Optional providers may charge usage under your existing agreement with them; Lunaver does not process those payments. FULLY USABLE WITHOUT ANY KEY Lunaver Studio can be used without an API key or Lunaver account. Available Apple system features and optionally installed local AI models (MLX) can support writing, planning, and evaluation on-device, depending on your Mac, macOS version, and model. Cloud models are an additional route, not a requirement. A REAL WRITING STUDIO, NOT A VENDING MACHINE Instead of push-button mass production you get a tool for authors: a full editor with dictation and voice control, a Story Bible for characters and places, multi-stage quality loops that review and improve chapters, and Lumi, the assistant who guides you through every step. You remain the author — the AI is your editing desk. GERMAN AND ENGLISH, BOTH FIRST-CLASS Lunaver Studio is built bilingual: an English and German interface with announcements across core workflows, plus proper German typography for print-ready output. PUBLISHING FROM ONE SOURCE • eBook (EPUB), print PDF, DOCX, Markdown • Audiobook export with chapter markers and ACX checks • Braille: BRF, Unicode braille and DAISY • Bundled files for supported KDP production steps ACCESSIBLE FROM THE GROUND UP VoiceOver, keyboard and voice were considered from the start — built by an author who is losing his own eyesight. Labeled controls and audible status messages support the core path from writing through export. BUY ONCE, DONE No subscriptions, no in-app purchases, no credits. Its included features require no additional Studio purchase. Optional providers may charge usage under your existing agreement with them; Lunaver does not process those payments. WHO IS IT FOR? For authors and self-publishers who want more than a raw draft: control over every chapter, verifiable quality, and a manuscript that belongs to no one but you. LUNAVER OR LUNAVER STUDIO? Prefer to write 100% offline with no cloud option at all? Then our app “Lunaver” is the right choice. Lunaver Studio is the one-time-purchase edition for authors who also want to plug in their own cloud keys and choose from more models. HONEST AND UPFRONT • Cloud usage requires your own API keys; costs are incurred directly with the respective provider. • Without keys, Studio uses its available local AI routes on-device. • No tracking, no analytics SDKs, no Lunaver AI backend.
