Getting words down
Squibler
An outlining and drafting app that will try to expand a premise into chapters or a screenplay. Speed is the point, and it shows: structure comes out fast, sentences come out generic, and you should expect to rewrite. Handy as a project container if you already know the story.
Best for
Writers who want a structured project and a fast first pass they are willing to throw away in revision.
Pricing
Subscription. Paid writing plans. A limited free project is often available; treat any generated full draft as a rough pass.

Squibler
An AI book and screenplay generator with an editor, outlines and story elements, on a credit-based plan.
- writers (vendor figure)
- free AI credits per month
- Plus per month, billed annually
What it is
Squibler is an AI writing platform built around generating long-form fiction. It can produce full-length books and screenplays from a prompt, then lets you refine them in an editor with outlines, a Smart Writer assistant, story elements (characters, locations and so on) and visuals. It says it is used by 20,000+ writers.
Who it's for
- Writers who want a fast first draft to react to and rewrite.
- Screenwriters who want AI help in script format.
- Hobbyists exploring an idea before committing.
Writers who want tight control of every sentence may find whole-book generation too hands-off.
Key features in practice
- Book and screenplay generation from a premise.
- Outlines you can restructure before or after generating.
- Smart Writer to continue, expand or rewrite passages in the editor.
- Elements for tracking characters and world details.
- Visuals to generate images for characters and scenes.

ChatGPT
The general assistant most writers already have open. Useful for brainstorming, blurb variants, and line rewrites if you paste the scene and say what you want. It does not hold a novel together unless you build that memory yourself with projects or files, and it will invent sources if you let it.
Best for Writers who want one flexible assistant and will bring their own outline, pages, and skepticism.

Claude
A general assistant that writers often prefer for long passages, tone, and a calmer revision pass. Projects can hold notes and chapters you upload. It is still a chat, not a novel app: continuity across a whole book is only as good as the pages you put in front of it.
Best for Drafting and revision when you want a careful reader more than a plot machine.

Gemini
Google's assistant, practical if your research and drafts already live in Docs or Drive. It will brainstorm and rewrite like the other general models, with the same habit of sounding finished before the thinking is. For source-grounded reading, NotebookLM is the closer sibling and is listed on its own.
Best for Writers already working in Google's tools who want a second model without a new app.
