In their own words
Quillstone
Quillstone combines research, drafting, fact-checking, audiobook creation, cover design, and publishing exports for journalists and nonfiction authors. It gathers PDFs, documents, notes, and offline references into an outlining workflow. Private AI tools can rewrite, expand, tighten, proofread, or continue prose using a sample of the writer’s work. Its fact checker adds inline citations, needs-citation markers, and a verification report. The app prepares EPUB, PDF, and M4B outputs, plus covers, metadata, and publishing checklists. Local chaptered audiobooks and layered cover designs are supported, with optional cloud narration and image generation. Quillstone Free costs nothing, billed forever; Pro costs $89, paid once as a one-time license. The Mac app is offline by default without analytics or telemetry, and project materials remain on the Mac. It requires an Apple Silicon Mac with M1 or later and macOS 15 or newer.
