Non-destructive iterative writing.

Editorial is designed to be beautiful. Every theme has been carefully hand-coded for a polished appearance, and the application is also fully optimized for high-DPI monitors.

Every paragraph can be an independent section that holds multiple variations. Write a new take, compare it against the original, and switch the active version with a click. Your earlier drafts are never lost.

• Offline multilingual spell-checker with project-specific dictionaries for your characters, places, and terms • Dedicated Notes, Lore, Summary, and Outline blocks. Each holds multiple versions and feeds context to the AI • Add Images, Highlights, Arrows • Visual word diff • Visual Markdown formatting: headings, bold, italic, lists: rendered inline or as markdown • Label any block for organization and page breaks • Export to PDF, DOCX, or Markdown with formatting, images, and structure preserved • Super lean and fast, just pure native code

One-time purchase, yours forever.

Drag blocks to restructure your document. Split paragraphs, merge them, add section breaks and headings. The outline lives in the writing itself. No separate planning document needed.

Send any block to a local or remote LLM with a single action. Ask it to tighten the prose, fix grammar, change the tone, or continue writing. The response returns as a new variation, ready to compare, revise, accept, or discard. This is where block-based editing becomes especially useful. Even a small local LLM model that might lose track of a long manuscript can work effectively when the text is divided into focused, manageable blocks.

Chain editorial actions into a reusable recipe: rewrite every block, summarize chapters, collapse to the active draft, save incremental snapshots. Pick the steps, set the parameters, hit Run.

It wouldn't be a MediaChance product without something slightly dangerous. Editorial includes an AI-focused scripting language for deeper control. Automate contextual rewrites, cleanup passes, continuity checks, or build multi-stage AI workflows that act as full editorial agents. But don’t worry about programming! We published a comprehensive scripting guide specifically for AI. Attach it to your favorite AI Chatbot and let it write your scripts for you. Check the included short_story_maker.bas and text_adventure.bas to see how far scripting can go.

Attach summaries, lore notes, and outlines to your blocks. It’s for you and for AI. When you send a prompt, Editorial can include preceding paragraphs, accumulated summaries, and world-building context, so the LLM sees what you see.

Publish to PDF or DOCX with headings, bullet lists, inline formatting, and images preserved. Or export plain text for whatever comes next.

Start a rewrite from the polished version or go back to the raw original. It's your call. Each block remembers where it came from, so you can branch off from any point in the editing history. Instead of going through a 90,000-word manuscript wondering “did I already fix this scene?”, the versions tell you immediately which blocks have already been reworked and which ones are still on their first draft.

Version 1.5 (7/4/2026) • Interactive Merge: The new Interactive Merge view compares your block against the model's suggestion as a two-line chip display: click any chip to accept or reject that change, or take whole rewritten sentences in one click. • Merge two versions of a block. The same tool works between a block's own versions via the new Merge Versions button — weave the best sentences of two drafts into one and save the result over the current version or as a new one. A color-coded selector steps through the block's other versions. • Blocks with multiple versions: Split and join now work on any text block, no longer only on single-version blocks. Splitting maps your chosen split point into every version by sentence alignment; joining combines versions slot by slot. • Simple Chat turns the right pane into a plain conversation with your configured LLM - for questions, brainstorming, and research that shouldn't touch the manuscript. • Markdown round trip with images (More Export → Export MD file with images) writes your manuscript as markdown plus every Image block as a PNG in a <name>_images folder, referenced from the text. Image effects are baked into the exported pixels. More Import → MD Files with Images re-imports the markdown and rebuilds the Image blocks — edit your text in any external editor and come back without losing the images. • File safety: Rotating backups on every save (.bak1–.bak3 next to your file), timed autosave to a sidecar file, and crash recovery that offers your latest unsaved changes on the next open. Configure both under Settings → Safety Settings. • Other fixes and small additions Version 1.1 (5/1/2026) • Reworked text import and auto-splitting into a more robust version that preserves markdown structure. (goal is more reliable markdown round trip - like exporting in markdown, then importing it again to editorial) • Markdown headings, lists, tables, code blocks, blockquotes, and dividers are now kept as structural blocks instead of being merged into surrounding text. • Large prose and dialogue blocks are split more evenly at natural line or sentence boundaries. • Short prose fragments are merged more intelligently, while dialogue stays separate from narration. • Improved chapter-heading detection to reduce false positives such as normal sentences starting with “Part” or “Book”. • Added Settings > Text Chunking controls for merge length, maximum block length, heading demotion, and prose chapter detection. • Fixed markdown tables being split across multiple blocks during import.

(Trial versions work also as an update for the full version)

Version 1.5 (July/4/2026)

The new Interactive Merge view compares your block against the LLM model's rewriting suggestion as a two-line chip display: click any chip to accept or reject that change, or take whole rewritten paragraph in one click.

See Release Notes

Editorial is a writing and editing application for prose. Instead of treating your manuscript as one long document, it treats it as what it really is: a sequence of paragraphs, each worth working on in its own right.

Every block keeps its own version history, so you can rewrite freely, compare alternatives side by side, and never lose a line you loved. And when you bring LLM into the process, it stays on your terms: suggestions appear next to your text, and you take or leave them word by word.
