Editorial AI - Meet Eddy
A Writing Partner Who Actually Reads Your Work
Most AI tools give you generic suggestions. Eddy gives you something better — a collaborator who lives inside your book's manuscript, knows your characters, understands your voice, and can act on what you ask. No copy-pasting. No context-switching. Just write.
-
Rewrites in your voice, not a generic one Eddy learns your writing style and uses it when suggesting edits, rewrites, and new passages — so the words still sound like you.
-
Ask, and it's done — right in the editor Select a paragraph, ask Eddy to fix it, and the change happens in place. No copy-pasting between windows.
-
Deep-dive craft analysis, one click away Style, plot structure, character arcs, dialogue — Eddy can review any layer of your manuscript and give you actionable feedback.
-
Research built right in Ask Eddy to look something up and it returns structured sources — saved to your manuscript so you can cite them later without hunting.
-
Talk to Eddy, not just type Voice input lets you brainstorm, dictate, and revise hands-free — especially useful during ideation or on long revision passes.
Characters + World Building
Your Characters, Your World, Brought to Life
Storyloft doesn't just generate images — it builds a visual identity for your book. Characters stay consistent from chapter illustration to cover. Scenes reference your cast. Your world has a look and a feel that carries through every asset you create.
-
Scene illustrations that know your characters Drop a character's name into a scene description and Storyloft pulls their reference to keep them visually consistent — chapter after chapter.
-
Character & artifact libraries Generate characters or world objects in grouped variants, each saved with profile metadata so your visual inventory grows alongside your story.
-
Precision editing without starting over Paint a mask on any area of an image, describe the change you want, and Storyloft applies it — preserving everything you've already established.
-
Style presets that lock your visual voice Define a visual style once. Apply it to every scene, character, and cover asset so your whole book feels like one coherent world.
Cover & Design AI
From First Impression to Last Page
Your cover is the first thing a reader judges — and it needs to feel like your book, not a template. Storyloft takes your manuscript's characters, palette, and tone and turns them into cover art, back-cover copy, and design-ready assets. Professional packaging, built from the inside out.
-
Cover art that reflects your actual story Storyloft reads your manuscript's characters and visual style to generate cover art that's consistent with the world you've already built — not generic stock imagery.
-
Iterate in conversation, refine until it's right Describe what you want, see a result, then keep refining in plain language. No design software. No prompt engineering.
-
Back-cover blurb, written in your genre's voice Storyloft generates a hook-first, two-paragraph back-cover summary using your manuscript content — ready to copy, or polish from a strong start.
-
Text-ready backgrounds, automatically generated Storyloft creates abstract, palette-matched backgrounds with contrast zones built in — so your title and author name are always legible. You can always upload your own too.
