Best NovelAI Alternatives

AI Dungeon has a free tier, iPhone and Android apps, and a web player. The free tier gets 4k tokens of context on most models, nine story generators and 25 Memories. Paid tiers start at $14.99 a month for 8k of context, against NovelAI's 8,192 tokens at $10, and run up to $99.99 for 64k, with two official pages disagreeing on Ultimate. It states its adult policy: a Mature level you confirm as 18+, an in-play filter against sexual content involving people under 18 even on Mature, and rules for public content.

What you pay for the free tier and the apps is price per token of context, and text generation is not unlimited. Whether Mature works on the free tier is not stated. AI Dungeon against NovelAI compares them, and our AI Dungeon alternatives page has the context-per-dollar table.

DreamGen is an AI story writer and role-play platform with a free tier of 200 monthly credits and 25 daily credits. Starter is $7.83 a month at list price with a 5,000-token context, Advanced $19.35 with 15,000 and Pro $48.30 with 30,000. It is about $2 below NovelAI's entry price and starts free, but its "unlimited" has an asterisk and monthly token caps, third-party models cost credits, and it is web only with no store app found.

On policy, DreamGen is close to NovelAI: its Terms do not ban adult content but no sentence permits it. They do bar sexual content involving fictional people under 18, and the Terms and Privacy FAQ say private stories are not used for training unless you opt in, while automated moderation scans private content.

Erota generates explicit stories from a form where you pick acts, themes, perspective, style, length, language and model. A free account gets 15 daily credits that expire each day, enough for one story on the Apprentice model at 1 credit, and Premium is $9.90 a month on monthly billing with 200 monthly credits, the stronger models and text-to-speech listening. Its Terms (last updated 3/18/2026) restrict only sexual content involving people under 18 or animals, rape or violence, scat and vore, and its footer says all characters are 18 or older.

It is a different tool: a story generator, not a co-writing editor, with no store app and no published context size. Credit costs are inconsistent across its pages (the FAQ says Artisan 2 and Master 4, the homepage model labels say 3x, 4x and 6x), so the cost of a story is not settled. Listening costs 8 credits at Standard quality.

Sudowrite is an AI writing partner for novelists, with Write, Rewrite, Describe, Expand and brainstorming tools around a Story Bible. It has its own models, Muse and Ballad, plus 30+ others. Its docs rate Muse's content filter as "virtually none" and say it "won't shy away from adult content", while the OpenAI-based models avoid explicit sexual content. Plans are Hobby & Student at $19 a month ($10 on annual billing), Professional at $29 ($22) and Max at $59 ($44), with credits and not unlimited text: 225,000, 1,000,000 and 2,000,000 a month.

It is a writers' tool, not a reading app, and there is no free plan, only a trial. Terms and docs contradict each other on refunds. The Terms prohibit using it to create sexually explicit content featuring people under 18, and also list "any obscene or immoral purpose", which sits awkwardly with adult writing. It has mobile companion apps, with higher App Store prices. See NovelAI against Sudowrite.

NovelCrafter is novel-writing software with planning, a Codex story bible, a prose editor and chat, and it ships no AI model. You connect an outside vendor, for example OpenRouter, or run a local model, and pay that vendor separately. Plans run from Scribe at $4 a month with no AI features to Specialist at $20, there is a 21-day trial with no card needed, and the AI features begin at Hobbyist, $8 a month, with your own key.

That makes content rules the model's business. Its help guide says NSFW "is whatever a model or its provider has decided warrants moderation", and its own Terms bar only unlawful use, infringement and interference with the app. We found no published rule on sexual content involving people under 18 in the pages we read. It is a web app, we found no mobile app, and the total cost depends on which model you connect.
