Best AI for Writing a Novel

This post is written by the TypeTak team, and TypeTak is one of the tools compared. Read it with that in mind. Prices and features come from each tool's official pages as of October 2026 and may change.

What is an AI novel editor?

An AI novel editor puts the manuscript, your story bible, and the AI in one place. You can write fiction with a general AI chat like ChatGPT or Claude, but a chat is built around conversations, so your manuscript and notes live somewhere else and get pasted in as you go. In an AI novel editor, the AI reads your manuscript and lore directly, and what you write becomes the manuscript right where you wrote it.

Here we line up four AI novel editors (TypeTak, Sudowrite, Novelcrafter, and NovelAI) with the two general AI chats, ChatGPT and Claude.

What to look for

The problem writers run into most with AI is the AI forgetting what was already decided. If a character's voice or powers from chapter 3 come out different in the chapter 30 draft, fixing it can take longer than the AI saved you. So this comparison starts with how each tool remembers your lore.

• Remembering your lore: where characters, places, and rules live, and how the AI reads them while it writes
• Drafting: whether it drafts a scene or chapter at a time, and keeps to your length and style
• Revision: whether you can rework a selected passage and get feedback on the whole manuscript
• The writing screen: whether it's comfortable for long sessions
• Pricing: how the cost grows in a month when you use the AI a lot

1. Remembering your lore

The AI knows nothing outside the text it's reading right now. So all five keep your lore somewhere separate and have the AI read it as it writes. They differ in how easily that lore builds up and how closely it's tied to the manuscript.

Sudowrite's Story Bible is both a place for your lore and the starting point the story is generated from. Give it a few lines of ideas and a synopsis, and the AI fills in character and worldbuilding cards that feed straight into the outline and draft. In ChatGPT and Claude, you upload your notes to a project and add instructions, and every chat in that project draws on them. When the lore changes, you edit the file and upload it again.

Feeding lore to the AI — Once your lore runs to hundreds of entries, the AI can't read it all at once, so only what the current scene needs should go in. TypeTak, Novelcrafter, and NovelAI pass an entry to the AI when its name shows up in the text. Of these, NovelAI's Lorebook gives you the finest control over when, and how much, lore reaches the AI: keywords can be regular expressions, and for each entry you set whether it's always in, how long it can run, and where it goes in the context. On paid plans, Claude switches a large project to searching its knowledge for the parts it needs, which lets a project hold up to ten times more material.

Worldbuilding in conversation — your lore builds up as you talk. New characters, places, and rules get decided as you talk with the agent. TypeTak collects what you decide in the World backlog below the chat box; click Organize and it's filed into your World, with the conversation it came from as its source, so you can always check why you decided it.

Tracking appearances — Novelcrafter's Codex ties in most closely with the manuscript. Register names and aliases, and it finds mentions across your manuscript, scene summaries, and chats, with a heatmap of who appears in which scene. Of the five, only Novelcrafter has this, and it's handy for spotting a character who's been offstage too long.

Lore over time — For lore that changes along the way, like a title or an allegiance, Novelcrafter's Progressions record each stage separately. TypeTak keeps these changes as spans instead of overwriting them, so a change mid-serial doesn't get mixed up with earlier chapters.

2. Drafting

Each tool gets you past a stuck scene in its own way. All but NovelAI draft a scene or chapter at a time, while NovelAI builds a scene through short continuations. Which feels better depends on how much of the story you plan ahead.

Drafting through conversation — In TypeTak, you get to a draft by talking it through with the agent. Click Organize and the plot points you settled in conversation are filed as cards on a board in your World, such as one called "Story". When you hand off a draft, you can see the plan first: adjust the outline and length on the draft plan card in chat, confirm, and it writes to that plan; ask it to just write, and it goes straight ahead.

ChatGPT and Claude also draft in conversation. To get another version, you send the request again, or you open the text in a window beside the chat (ChatGPT's canvas, Claude's artifacts) and ask for changes. Then you copy the draft over to wherever you keep the manuscript.

A passage at a time — In NovelAI, you and the AI take turns building the story. Each press of generate adds up to 600 characters, and if you don't like it, you retry for another version. Every version stays as a branch, so you can go back and take a different path. Working in short steps makes it easy to steer paragraph by paragraph.

Hitting your target length — If every chapter of your serial has to hit a set length, the count matters. AI models rarely keep to a requested length, so TypeTak runs the draft through a separate step to hit the length set on the draft plan card. Novelcrafter puts the length you pick for each beat into the prompt.

Keeping your voice — If you want drafts in your own style, TypeTak and Sudowrite make it easiest. Note point of view, sentence rhythm, how you handle dialogue and description, and pacing in TypeTak's Writing Style or Sudowrite's Style, and drafts follow it; either can also read a sample of your prose and write the style for you. In ChatGPT and Claude, you describe your style in the project instructions; in NovelAI, in the Author's Note.

Fiction-trained models — If general AI prose feels flat to you, Sudowrite and NovelAI are worth a try. Sudowrite uses Muse, its own model trained on published fiction, and NovelAI uses its own models trained for storytelling. Sudowrite also offers more than thirty other models. Some users still preferred a general AI.

3. Revision

Revising usually takes longer than drafting. How much work it is depends on whether you select a passage and fix it right in the editor, or paste it into a chat and copy the result back.

Sudowrite is strong at making prose read like fiction. Rewrite reworks a passage, Describe adds sensory detail, and Expand builds out a rushed scene, with more than 1,000 community plugins on top. In Novelcrafter, you call up Expand, Rephrase, or Shorten from the selection menu, and if none of them fits, you build your own with Custom Prompts and keep it in the same menu.

Polishing the whole manuscript — In TypeTak, you revise the whole page from the editor toolbar. Revision adds comments and alternatives to sentences that need fixing, Proofreading marks spelling, grammar, and awkward phrasing, and Feedback points out where the text contradicts your World. Every suggestion appears on the page, and you apply only what you like.

Sudowrite's Feedback names five areas to improve, and developmental edits, line edits, and beta reads start at the Professional plan. Paste a manuscript into ChatGPT or Claude and ask for notes, and you get a long, detailed reply. In ChatGPT's canvas, Suggest edits leaves a comment on each spot to fix.

4. The writing screen

You spend hours in these tools, so a comfortable screen matters. The four AI novel editors put the manuscript in the middle with lists and tools on either side. ChatGPT and Claude put the conversation in the middle and open your text in a window beside it.

Built for long sessions — TypeTak's Split view keeps your World notes or an earlier chapter open beside the page as you write. Typewriter mode holds the line you're writing at the middle of the screen, so your eyes don't drift to the bottom as the text grows.

Where the tools sit — Sudowrite lines Write, Rewrite, Describe, and Brainstorm buttons across the top of the manuscript and stacks results in boxes on the right, so tools are easy to find. Novelcrafter switches between Plan, Write, Chat, and Review with tabs along the top and keeps the Codex in the left sidebar for lookups mid-draft. NovelAI colors text by whether you or the AI wrote it, so you always know which sentences are yours.

Pricing

Usage included in the plan — TypeTak, Sudowrite, ChatGPT, and Claude give each plan a set amount of AI use. When it runs out, you wait for the next cycle or upgrade. On TypeTak you can add extra usage for a busy month and scale it back afterward. To keep writing without paying, TypeTak, ChatGPT, and Claude have free plans.

Unlimited generation — NovelAI's paid plans put no cap on text generations. Higher plans let the AI read further back in your text at once.

Bring your own AI — Novelcrafter's subscription doesn't include AI costs. From the Hobbyist plan up, you connect a key from an AI provider and pay that provider separately. Connect a free model on OpenRouter or a model running on your own computer, and you can use AI without paying for it, though you'll need to get a key or install a model first.

TypeTak — Pro $12/month ($9/month billed yearly), Max $40/month ($29/month billed yearly). Sudowrite — Hobby & Student $10/month, Professional $22/month, Max $44/month (up to 50% off billed yearly). Novelcrafter — Scribe $4/month (no AI), Hobbyist $8/month, Artisan $14/month, Specialist $20/month (two months free billed yearly). NovelAI — Tablet $10/month, Scroll $15/month, Opus $25/month. ChatGPT — Plus $20/month, with Pro above it. Claude — Pro $20/month ($17/month billed yearly), Max from $100/month.
