About Deep Realms
What Is Deep Realms
Deep Realms is an AI storytelling and writing platform that runs in your browser. You create "worlds," and each world holds two things: the story text itself, plus a set of world lore notes that describe the setting, rules, and cast. The AI writer then continues the story while staying inside the universe you laid out.
The pitch is freedom. The same platform that handles a cozy fantasy tale also hosts an unfiltered NSFW mode, so adult writers can take a story anywhere without fighting a content filter. Between those two ends, you get tools that most casual AI chat apps skip: an author's note for style instructions, a memory section for past events, and an adventure mode that turns the session into a choose-your-own-adventure run.
The trade-offs come down to how you pay and where you write. Deep Realms runs on credits, and features like world lore cost more per generation because the AI pulls in more context. There's no native mobile app, so everything happens on the web. If you want a quick throwaway chat, a general chatbot does that better. Deep Realms is built for people who care about continuity across a long story.
Getting Started
- Create a free account on the official site with an email address or a linked login.
- Start a new world and paste in your story text, or pick a public world from the gallery to remix.
- Fill the world lore fields with your setting, locations, and characters so the AI stays on track.
- Write an author's note to fix the tone and style, like "keep the pacing slow and dialogue-heavy."
- Play your story, then adjust the memory section or turn on adventure mode as the plot grows.

Key features
Worlds and World Lore
A world bundles your story text with lore notes on setting, rules, and characters. The AI reads those notes while it writes, so a detail you set in chapter one can still hold up in chapter twenty.
Unfiltered NSFW Writer
A toggle turns NSFW generation on or off. With it on, the writer handles mature themes and scenes without the content blocks many mainstream assistants apply, which is the main draw for adult fiction writers.
Memory Section and Automatic Memory
You can list past events for the AI to remember, or leave automatic memory on and let it track the plot for you. The longer a story runs, the more this matters, since generation quality drops once an AI forgets what already happened.
Author's Note
A dedicated box for instructions to the AI, such as a target writing style or a tone to hold. It's the main lever for steering voice and pacing without editing the story text itself.
Adventure Mode
This shifts the session toward a choose-your-own-adventure feel. The AI becomes less likely to act for your character, so you keep control of the decisions rather than watching the story move without you.
Enhanced Output and Memory Boost
Enhanced Output rewrites text as it generates to cut repetition, and Memory Boost raises the memory limit on supported models. Both aim at the same problem: keeping long stories readable.
Pros and cons
Pros
- The world lore system keeps long stories coherent, which generic chatbots handle poorly.
- The NSFW toggle answers a real need for adult writers that filtered assistants won't touch.
- Memory controls, automatic or manual, give you a direct say in what the AI recalls.
- Adventure mode hands narrative control back to the writer instead of the model.
- It runs in the browser, so there's nothing to install and you can pick up on any machine.
Cons
- Pricing is credit-based and not published, so it's hard to estimate cost before you start.
- The world lore feature bills dynamically per generation, meaning you can't predict the price of a single run in advance.
- There's no mobile app, which limits writing to a desktop or laptop browser.
- Output quality still depends on the underlying model, and reviews note that longer stories need manual memory upkeep.
