Features

From drafting to export — everything Core can do.

AI Chat

An AI chat panel that lives beside your editor. It reads every file in your project — manuscripts, notes, and references — and responds with full awareness of your work.

  • Access to all project files — understands themes, structure, and writing style
  • Writing-specific commands: "Analyze the structure," "Give a literary critique," and more — with high-quality responses
  • Conversation history auto-saved per project. Bookmark important exchanges
  • Quote selected text into chat with "Quote to Chat" for pinpoint discussion

Research

Type a natural-language query and the AI searches multiple library databases at once. Every result is a real, verified source — and digitized works are searched down to their full text, with illustrations you can browse inline.

  • Searches the National Diet Library (NDL), Library of Congress (LOC), Open Library, and Internet Archive
  • NDL Digital Collections are searched by full text (OCR) — jump straight to the page where a word appears inside a book
  • Illustration gallery — browse the plates of illustrated works inline; expanded automatically when your query is asking to see images
  • Customizable search scope — Japanese only, academic papers only, global, etc.
  • Save any result as a reference note inside your project. The AI chat can reference it too
  • Deep Research mode (Max plan) for harder-to-find sources

Workspaces

Write in Editor mode, plan structure in Outliner mode, rearrange scenes in Corkboard mode. Three workspaces for different stages of your manuscript.

  • Editor — write in a rich text editor
  • Outliner — edit the full hierarchy of your manuscript
  • Corkboard — see and rearrange scenes as cards
  • ⌃⌘1 / ⌃⌘2 / ⌃⌘3 for one-tap switching
Core's three workspace modes — Editor, Outliner, and Corkboard.

Focus Mode

A fullscreen writing mode that hides every UI element. Typewriter mode keeps the cursor fixed at the center of the screen.

  • ⌃⌘F to toggle focus mode, ⌃⌘T to toggle typewriter mode
  • Works with vertical writing mode
Core focus mode with all UI elements hidden for distraction-free fullscreen writing.

Import & Export

Import Scrivener (.scriv) projects with their folder structure intact. Word (.docx) imports preserve ruby, footnotes, comments, images, and headings. Don't let your tools stop you from switching.

  • Scrivener — preserves chapter and scene hierarchy
  • Word — retains formatting (ruby, footnotes, comments, images, headings, lists)
  • Export to PDF / EPUB / DOCX while keeping ruby, emphasis dots, and vertical layout
  • Export the entire project or selected files only

See the full compatibility table in Help. Migrating from Scrivener or Word? See the side-by-side.

Proof of Authorship

Core records what you type and what you paste as you write, then exports a signed "authorship certificate" bundling a text hash, the provenance, and your typing rhythm. Instead of guessing whether text was AI-generated, the tool you wrote with carries the provenance as evidence.

  • Records which passages you typed by hand and which you pasted
  • A text hash and an Ed25519 signature detect any tampering after export
  • Export the certificate as a PDF — anyone can verify it on the verification page

Read how it works on the authorship overview. Exported certificates can be checked on the verification page.

Writing Progress

A dashboard that shows daily output and goal progress. It only counts characters you actually typed — pasting and deleting won't skew the numbers.

  • Counts only typed characters (paste and delete are excluded)
  • Daily, weekly, and monthly graphs to track your habit
  • ⌃⌘P or click the top progress bar for instant access
