Inside the app
Everything you need to publish
Chapter management
Drag-and-drop spine with front matter, chapters, back matter, part dividers, and blank pages. Per-chapter status tracking (Draft / In progress / Complete / Final) and writing-goal progress, target date, and streak.
Book themes
Five built-in typography presets — Classic, Literary, Modern, Manuscript, and Book Club — each tuned for EPUB and print PDF. Free edition uses Classic; a license unlocks the full set.
EPUB & PDF export
EPUB for every major store with automatic validation; print-ready PDF with a Black & White or full Colour interior toggle. Licensed users choose from seven trade sizes (pocket through royal and A5); EPUB reflows for each device.
Story Bible
Track characters, scenes, locations, items, factions, events, themes, and research sources. Tags, colour coding, and project-wide search.
In-app AI support
Licensed users get contextual in-app support grounded in official help topics, with email escalation when needed. Requires a valid license key.
AI writing tools
Connect your own API key — OpenAI, Anthropic (Claude), or a custom/local endpoint (e.g. Ollama, LM Studio). Quail does not charge for AI usage; keys stay on your machine.
- Blurb generator — tagline, standard, and full KDP description from your manuscript
- KDP keywords & categories — after a blurb; comps and browse paths
- Sensitivity & consistency — full-manuscript reports; contradiction and facts ledger
- Story Bible — extract entities automatically from your manuscript
- Timeline tools — Visual timeline of events; chronological plot from chapters
- Realism check — select any passage in the editor and an inline Ask pill opens a conversation popover for medical / historical / terminology checks without leaving the page. Cost estimates before long runs; results saved in the project.
Snippet library & cross-platform
Reusable blocks for copyright pages and about-the-author. Native app for macOS and Windows — fast and offline.
