The record

Purpose: Quillstone combines research, drafting, fact-checking, audiobook creation, cover design, and book publishing exports for journalists and nonfiction authors.
Research workflow: The app can gather PDFs, documents, notes, and offline reference material and help shape them into an outline.
Writing tools: Its private AI writing tools can rewrite, expand, tighten, proofread, or continue prose anchored to a sample of the writer’s work.
Fact checking: A built-in fact checker provides inline citations, needs-citation markers, and a verification report.
Publishing outputs: Quillstone can prepare EPUB, PDF, M4B, covers, metadata, and publishing checklists.
Audiobooks and covers: The app supports local chaptered audiobook creation and layered cover design, with optional cloud narration and image generation.
Privacy: The Mac app is offline by default, has no analytics or telemetry, and sends selected text directly to a chosen cloud provider only when the user enables it.
Cloud providers: The privacy policy names OpenAI and Anthropic for cloud language models and ElevenLabs for optional narration.
Other external services: The privacy policy identifies Brave for web search, OpenAI for online fact-checking, Hugging Face and CivitAI for model downloads, Sparkle for updates, and Lemon Squeezy for license validation.
Local data: The privacy policy says manuscripts, outlines, characters, covers, generated images, narration audio, and exports are stored on the Mac, and entered API keys are encrypted there.
System requirements: Quillstone requires an Apple Silicon Mac (M1 or later) running macOS 15 or newer.
Intended users: Quillstone is designed for serious nonfiction such as reporting, biography, narrative history, manuals, textbooks, essays, and research-led books.
Support: Quillstone offers email support and says a real person usually responds within two business days.
