So, you’re ready to create something amazing. Maybe a fantasy epic. Or a sci-fi thriller. Or even a slice-of-life drama. But you want a little boost from AI. You’ve probably heard of Sudowrite, HoloAI, and NovelAI. But which one should you choose?
Let’s break them down in a fun, simple way. Imagine three writing buddies at a storytelling camp. Each one has its own style, tools, and superpowers.
Sudowrite – The Clever Helper
Sudowrite is like the clever writing partner who helps when you’re stuck. It works with your own writing and adds cool flavor when you need it.
- Uses GPT-4 (a modern AI model that “gets” what you’re writing)
- Great for editing, expanding, and rewriting
- Built to work inside your writing process
One brilliant feature is “Wormhole”. Tell Sudowrite what you want. It shows you different versions of what could happen next. Struggling with writer’s block? That wormhole is magic.
Sudowrite also offers tone-shifting, rephrasing, and even character brainstorming. It’s like writing with a friend who finishes your sentences—but in a really cool way.

HoloAI – The World Builder
Now meet HoloAI. It’s your RPG-loving, detailed-lore friend. HoloAI shines when you want to create big worlds, long dialogue scenes, or deep character backstories.
- Uses GPT-J or other open models (less advanced than GPT-4 but still solid)
- Lets you customize and train it on your own writing
- Built for roleplay and giant stories
HoloAI loves character sheets, custom memories, and lore entries. You can literally upload your own backstory files and let it study them!
It’s especially popular among fans of fanfiction or tabletop-style storytelling. Not the flashiest interface, but oh boy, the firepower is real.

NovelAI – The Imaginative Artist
Last but not least, we meet NovelAI. It’s the dreamy artist in our trio. It’s designed for creative writing and generating gorgeous prose that sounds like literature.
- Offers strong narrative generation tools
- Includes an image generator (for fantasy & anime-style art!)
- Highly customizable and secure
Want to write in the voice of a classic author? Or generate anime scenes with your characters? NovelAI has your back. It even allows you to add “Memory functions”, so it remembers your plot points, character traits, and more as you write.
It’s ideal for fiction-focused writers who care a lot about style and tone. The AI can go on and on, and often surprises you with originality.
So, Which One Wins?
Honestly? It depends on you!
- Use Sudowrite if you want helpful edits and a buddy for drafting your novel.
- Use HoloAI if you’re making a deep world with long-form storytelling or character-based roleplay.
- Use NovelAI if you want poetic writing and a blend of words and images.
Each platform has cool tools and unique vibes:
Tool | Best For | Unique Feature |
---|---|---|
Sudowrite | Editing, expanding, creative help | Wormhole & tone-shifting |
HoloAI | Worldbuilding & roleplaying | Lore uploads & character memory |
NovelAI | Fiction writing & artistic vibes | Stylized writing & image generation |
It’s a great time to be a writer. With tools like these, you’re never alone at the keyboard. All three help you tell better stories, each in their own way.

So go ahead! Pick your sidekick and start creating. The story of your dreams is just a few keystrokes away.
