Narratomi vs NovelAI

Narratomi is a browser-based studio for writing and staging branching narrative games. Its editor places a live 3D stage alongside the script and choices, while a flow graph maps story routes and checks them as you write. Slash commands add choices, variables, and stage directions without code, and the compiler flags broken paths. Co-writers can work in the same scene live, and writers can create checkpoints, branch drafts, restore versions, and merge changes. Its AI staff writer drafts on its own branch, so writers can review, merge, rewind, or discard that work. Published stories open from a browser link without requiring a player account; anyone with the link can access them until they are unpublished. Writing, staging, and playing work in a modern desktop or phone browser without installation. User-created stories, scripts, and assets remain theirs. The free plan includes two projects, 50 monthly AI credits for mini models, 0.5 GB storage, and 1,000 monthly plays. Creator costs $12 per month billed annually and includes unlimited projects, 7,500 monthly AI credits, 5 GB storage, and 20,000 monthly plays.

NovelAI combines AI-assisted story writing with anime image generation and is available on the web, Android, and iOS. Its NovelAI Diffusion V5 generator can produce original characters, scenes, artwork, and full comic pages. Image controls include natural-language prompts, tags, character positioning, and action tags; separately defined characters can remain consistent across scenes. Inpainting, Director Tools, and a built-in canvas support image refinement. The homepage identifies GLM 4.6 as the model behind story generation, and the product supports long-form writing. The Paper trial includes 30 image generations, 50 text generations, and 100 text-to-speech generations. Paid plans start at $10 a month: Tablet and Scroll each include 1,000 subscription ImageAnlas, while Opus costs $25 a month and includes 10,000 subscription ImageAnlas and a 28,672-token context size. Anlas can also be purchased on demand for image generation. NovelAI says users retain ownership of created content and encrypts stories, lorebooks, scripts, and prompt chunks in the browser before saving.
