Novelist is a lightweight, extensible writing app for long-form creators. It stays fast on large manuscripts, supports CJK writing from the start, and combines a focused editor with plugins, export workflows, mind maps, and reviewable AI writing assistance.

Key Features

Long-Form Writing Performance — Built for large documents and manuscripts, keeping editing smooth even when files grow.

Writer-Friendly Editor — Markdown shortcuts render as clean formatting while typing, so writers do not need to switch between edit and preview modes.

AI Collaboration — AI chat and agent workflows support context mentions, editable retries, and structured SEARCH/REPLACE suggestions shown as reviewable word-level diffs.

Extensible Workflow — Plugin support, themes, shortcuts, split view, mind maps, export to HTML/PDF/DOCX/EPUB, and first-class Chinese, Japanese, and Korean writing support.
