aiWriter

Adult note: aiWriter is an unfiltered, adult-friendly fiction tool with a +18 toggle and an Unrestricted setting. It is built for mature fiction — romance, dark fantasy, horror and fanfic — and is not a general writing assistant.

Key facts: aiWriter is a free AI fiction writer built on its Deep Writer v2 engine. Its novel workspace takes a premise through a three-act outline and a character bible, then drafts chapter by chapter with the previous chapter, character bible and plot threads injected as context, so a long book stays consistent. Characters & Worlds lets you write 4,000-character descriptions and use pre-built fandom canon worlds. You can switch length (Sentence / Paragraph / Full), toggle between Skilled Writer v1 and Deep Writer v2, use Continue Writing to extend a story, and export to .txt, .doc, PDF or .epub.

Plans: Free: $0 — unlimited Skilled Writer v1, 10 Deep Writer v2 generations a month, stories of about 2,000 words, novel outlines only, 10 documents, no Continue Writing and no Characters & Worlds; ads may show. Plus: $8.49 a month ($84.90 a year) — 5,000 Deep v2 generations a month, unlimited length, Continue Writing, 1 book at a time, unlimited documents, 2 characters & worlds, no ads.

Best for: Fiction writers — romance, fantasy, fanfic and horror — who want an unfiltered, adult-friendly drafting tool with a real novel workspace. Who should skip it: anyone looking for a general writing assistant, or anyone who needs a filtered, SFW tool.

Pros

• Coherent, atmospheric fiction across genres — horror, dark fantasy and romance all read cleanly in hands-on testing, with no repetition or logic breaks
• A real novel workspace: outline, character bible and chapter-by-chapter drafting that keeps a long book consistent
• Characters & Worlds with 4,000-character descriptions and pre-built fandom canon worlds
• Exports to .txt, .doc, PDF and .epub, and you own the rights to the stories you generate

Watch out for

• "Full" length does not respect the word count — it writes roughly 380–500 words when asked for 300
• Continue-writing suggestion chips are sometimes off-tone for the scene
• It is an unfiltered, adult-friendly tool with a +18 toggle and an Unrestricted setting — not a general writing assistant
