Most writing software is built around vertical editing. You rewrite a paragraph, then rewrite it again, and the previous version is gone unless you keep duplicate files, buried notes, or a graveyard of “really_final_v4” documents.

Most AI assisted writing tools operate on huge chunks of text with vague prompts. The result is usually impressive for five seconds and disappointing five paragraphs later. Ask a typical AI editor to grammar-check 50,000 words, and there is a good chance it will confidently miss an entire novella in the middle. Editorial fixes this by giving AI a structured local workspace. Instead of processing giant text dumps, the AI works on small meaningful blocks, where the purpose stays visible and the revision target remains clear. • AI always processes only small blocks • the editorial goal is constantly reinforced • original text is preserved as a variation • multiple rewrites can be tested safely • nearby structure, summary and lore keeps the rewrite honest

It would not be a MediaChance product if we did not include something slightly dangerous. Editorial includes an AI-focused scripting language for people who want deeper control over their document workflows. That means you can automate things like: • contextual rewrites • repeated cleanup passes • block analysis • continuity checks • summary generation • export preparation • structured multi-stage AI workflows But don’t worry about programming, it’s 2026 after all! We published a comprehensive, AI-friendly scripting guide; simply attach it to your favorite LLM and ask it to write your editorial scripts.

A Text Editor for Lateral Thinking

Editorial is a different kind of text editing software that adds horizontal granular editing where each paragraphs can keep all the previous revisions.

Compare versions, switch between them, keep exploring, and collapse to a final choice only when it is truly better. This makes Editorial ideal for novel writing, scriptwriting, developmental editing, scene refinement, and AI-assisted rewriting workflows.

Editorial is especially useful for: • fiction writers refining scenes paragraph by paragraph • editors comparing multiple rewrites • screenwriters and scriptwriters testing alternate beats • story developers preserving lore and continuity • AI-assisted writers who want control instead of chaos • anyone who wants a more deliberate and precise revision workflow

Editorial is beautiful by design, with every theme hand-coded.

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, which ones are still on their reckless first draft, and exactly where the manuscript still needs surgery.

A built-in word diff shows you exactly how the versions differ.

In 2026 the AI itself can write the script for another AI.
