Quick Answer

An AI-assisted long-form writer: generates outlines, drafts chapters, and exports to EPUB or PDF. Prompts are sent to Venice AI (a third-party inference provider); Practical Web Tools does not retain manuscripts on its own servers. Export runs in your browser using pdf-lib and an EPUB packager — the output file is built client-side.

How It Works

1

Enter title, genre, target length, and a one-paragraph premise

2

Generate an outline; edit or regenerate sections until it reflects your book

3

Draft each chapter with AI assistance; revise every paragraph before accepting

4

Export to EPUB (for eReaders) or PDF

Key Facts

  • Outline → chapter draft → revise → export pipeline (EPUB 3 and PDF)
  • Cloud text generation runs on Venice AI; provider policy applies to your prompts once they reach their server
  • Manuscript text is stored in your browser localStorage so drafts persist across sessions
  • EPUB export follows the W3C EPUB 3 specification; PDF export uses pdf-lib
  • Bring-your-own API key supported for direct provider billing without a middleman
  • You own the output. AI-assisted text is not copyrightable on its own in the US; your edits and arrangement carry copyright

Frequently Asked Questions

Who is the provider behind the writing?

Text generation goes to Venice AI by default. You can paste your own Venice API key to bill directly. No third party touches the prompt once it leaves your browser other than the named provider.

Where are my manuscripts stored?

Draft content is kept in your browser's localStorage so it persists between sessions on the same device. Nothing is written to Practical Web Tools servers. If you clear browser data, drafts are deleted — export or copy regularly.

Who owns the output?

You own the assembled manuscript. Note that in the US, purely AI-generated text without human authorship cannot be registered for copyright. Your selection, arrangement, revision, and added writing establish authorship. Review the Copyright Office's 2023 guidance if this matters for your project.

What export formats are supported?

EPUB 3 (reflowable, works in Kindle after MOBI conversion, Apple Books, Kobo, Calibre) and PDF. Export runs locally in your browser.

Does this replace a human editor?

No. AI draft text is a starting point, not a finished book. Plan on a full self-edit pass and, for anything published commercially, a human copyeditor. The tool shortens the blank-page phase; it does not ship the book for you.

Can I use this for non-fiction or only fiction?

Both. For non-fiction, always fact-check every claim the model produces — LLMs generate confident-sounding statements that can be wrong. For fiction, watch for repeated phrasing and clichés that AI models fall into.
