ToolifyNav verdict
Squibler works as a drafting engine for long fiction and scripts. It is most useful for writers whose obstacle is finishing, since it can hand over a structured, complete draft and then support revision through outlines, elements and an approval-based co-writer. The output itself reads generic until a writer reshapes it, so the tool works best as scaffolding rather than a replacement for voice. Prospective users should also check whether their publisher or contest allows AI-assisted text. For hobbyists and early-stage authors who want momentum, the free plan is a low-risk way to see whether the workflow helps.
About
About Squibler
Squibler is a long-form writing app aimed at novelists, memoirists and screenwriters who want help getting from idea to complete draft. Its headline feature is full-length generation: describe your concept, genre and core elements and Squibler produces an entire book organized into chapters and scenes, or a full screenplay with formatted scenes and dialogue that follows screenplay conventions. You can also start by importing an existing manuscript and asking the AI to work on it.
That first draft is meant to become a working document rather than a finished product. A story-outline generator maps structure, pacing and character arcs before or after drafting, and outlines can be reorganized at any stage. Elements give characters, settings and key details a structured home, so the AI keeps them consistent across chapters. The AI Smart Writer acts as a co-author: you set an objective, it evaluates the text and proposes revisions, and you accept, reject or refine each suggestion. Squibler can also turn highlighted passages into images or short video sequences, useful for pitches, covers or mood boards.
The site includes templates for books, screenplays and characters, plus small tools such as title and plot generators. A free plan with monthly credits lets you test full book and screenplay creation, while paid plans add far more credits, whole-manuscript editing and PDF and DOCX export.
