NovelAI
- +Strong tooling for long-form fiction: Lorebook, memory, author's note, and modules keep characters and world details consistent
- +Well-regarded anime and illustration image generation (NovelAI Diffusion V4.5) with inpainting, vibe transfer, and a built-in canvas editor
- +Few content restrictions and a privacy-first stance (encrypted text storage; generated images reportedly not retained on its servers)
- -An assistant, not an autonomous agent: the user prompts, curates, and edits every story passage and image
- -Image generation is metered by Anlas credits on most plans, and the strongest text model (Erato) is gated to higher tiers
Sudowrite
- +Purpose-built for fiction, with tools (Story Bible, Describe, Expand) tuned to novel-writing rather than business copy
- +Muse model is reportedly trained only on fiction, aimed at more natural prose and dialogue than general-purpose chatbots
- +Transparent credit-based pricing with a no-credit-card free trial and full feature access on every paid tier
- -Copilot only: it drafts and suggests, the writer does all the structural and editorial work; it does not act autonomously
- -Credit system means heavy generation can burn through a month's allotment, and lower tiers do not roll credits over
