AnyStory

Every project holds the manuscript alongside character sheets, outlines, and worldbuilding notes in one sidebar. The AI draws on that material when it rewrites, so it keeps facts about your characters and plot consistent instead of losing them between sessions. That context is the difference between a tool that knows your book and one that only sees the paragraph in front of it.

You set a project's tone and style once, and the AI applies it to each Rewrite, Expand, Redraft, Humanize, or Summarize action. The goal is suggestions that sound like you wrote them, not like a chatbot filled the gap. It's the feature the product leans on hardest, and it's what separates it from plain chat tools that forget your voice each time.

The workspace lets you pick the AI model behind the writing actions rather than locking you into one. That matters if you've found a model whose prose you prefer, or if one handles your genre better than another. You can switch without moving your project to a different tool.

Every save is tracked, and each version stays accessible, with a diff-style preview of what an AI pass changed. If a rewrite tightens a sentence you liked or flattens a line, one click puts the earlier version back. Autosave runs on every change, so a dropped connection won't cost you a paragraph.

The workspace is built for books, novels, short stories, screenplays, essays, and blog posts, rather than short chat replies. For anyone comparing fiction writing software or weighing a screenplay writing app, the structure holds chapters and scenes as separate units while keeping them connected to the project's notes. Writers moving from a plain document get the organization they were building by hand.

AnyStory runs in a browser on Windows, Mac, and Linux, with no download or install step. That helps on machines where installs are blocked, and it means your project lives in the cloud rather than on one hard drive. The trade-off is that you need a steady connection and there's no offline mode.
