Squibler

AI writing partner built specifically for fiction and novelists.

Sudowrite is an AI writing tool aimed at fiction authors, with a Story Bible for outlining, Write/Expand/Describe tools that draft in the author's voice, and a Canvas for plotting arcs and themes. Unlike general assistants, it is tuned for long-form creative narrative rather than business or marketing copy.

Plan, write and organize your novel with bring-your-own-key AI.

Novelcrafter is a browser-based platform for fiction and non-fiction authors that pairs a full manuscript editor with a worldbuilding wiki called the Codex for characters, places and lore. AI features — scene generation, summaries, character extraction and beat-to-scene drafting — run through your own provider key, so you choose the model and pay the API rates directly. Plans start at $4/month after a free trial.

Subscription AI storyteller and anime image generator with encrypted stories.

NovelAI is a subscription platform for AI-assisted fiction writing and anime-style image generation, built around Anlatan's own storytelling models rather than general-purpose assistants. Paid tiers include unlimited text generation with adjustable context sizes, plus Anlas credits for its NAI Diffusion image models. Stories are stored end-to-end encrypted, so only the author can read them.
