Games Like AI Dungeon: Five Worth Moving To, and When to Stay
If you are looking for games like AI Dungeon, you are almost certainly not looking for a different text box. You are looking for the same open-ended freedom without the part that spoils a long run: forty turns in, the narrator forgets that the city fell, that your brother is dead, that magic costs something. Every option below is really a different answer to one question — who is responsible for remembering the world, you or the software. That is the axis this comparison uses, because it is the one that decides whether a campaign survives its first week.
AI Dungeon describes itself, on its own home page, as “a free AI text adventure game where players create open-ended stories, explore interactive worlds, and guide every choice online or in the app” (aidungeon.com, September 2026). That is an accurate description of the category it invented, and four of the five options here are attempts to keep that freedom while tightening something else.
The five options at a glance
| Option | What it is | Who keeps the lore straight | What it runs on | What you install |
|---|---|---|---|---|
| AI Dungeon | The original hosted sandbox | You, via memory entries and story cards | Their hosted models | Nothing |
| KoboldCpp | A single-file local engine plus the KoboldAI Lite UI | You, via memory and world info | A model file on your own machine | An executable, and a model |
| SillyTavern | A power-user front end for models you supply | You, via character cards and lorebooks | A backend you connect | The app, plus a backend |
| NovelAI | A subscription writing and image service | You, via its lorebook | Their hosted story model | Nothing |
| Talemate | An open-source multi-agent roleplay app | Dedicated world-state agents | APIs or a local backend you supply | The app, plus a backend |
| LLM RPG | A hosted game master that has read your novel | The product, from the book itself | Hosted, per plan | Nothing |
KoboldCpp: the one that asks nothing of the cloud
KoboldCpp is the practical successor to the original KoboldAI, and its repository states the pitch plainly: “an easy-to-use AI text-generation software for GGML and GGUF models” that is “a single self-contained distributable” building on llama.cpp (github.com/LostRuins/koboldcpp, September 2026). The project’s README lists “Single file executable, with no installation required and no external dependencies”, running “on CPU or GPU”, and it bundles the KoboldAI Lite interface “with editing tools, save formats, memory, world info, author’s note, characters, scenarios”, including an explicit adventure mode. Note that koboldai.org now resolves to that repository, which is worth knowing if you are chasing an old link.
Move here if privacy or cost is the reason you are leaving. Nothing you write leaves your machine, there is no subscription, and nothing can change the terms under you. The trade is that quality is bounded by your hardware, and the world’s memory is still a set of notes you maintain by hand.
Stay with AI Dungeon instead if you have no GPU to spare and no appetite for picking a model file. A hosted narrator you dislike still beats a local one you cannot run.
SillyTavern: maximum control, once you have a backend
SillyTavern presents itself as an “LLM Frontend for Power Users” (sillytavern.app, September 2026), and that is the whole of it: it is the interface, not the intelligence. You bring a backend — a local engine such as KoboldCpp, or a paid API — and in return you get the deepest control over prompts, characters and lorebooks available anywhere in this list.
It is the right move if you found AI Dungeon’s controls too shallow and enjoy the configuration as part of the hobby. It is the wrong move if you wanted to play tonight. We have written about this trade in more depth in our SillyTavern alternative piece, including who should stay.
NovelAI: a writing tool that will narrate if you ask
NovelAI is the odd one out, and its own positioning says so: its home page leads with image generation and calls itself “the #1 AI image generator tool for generating AI anime art or crafting epic stories”, with story generation offered as a space “built to write with you, not for you” (novelai.net, September 2026). Its FAQ states that “Our subscriptions start at $10/month” as of September 2026.
It is a prose instrument, not a game. Nothing adjudicates, nothing pushes back, nothing tells you that you failed. If what you missed about AI Dungeon was the writing quality, this is a real upgrade; if what you missed was the sense of playing against a world, it is a sidestep. Our NovelAI pricing breakdown covers what each tier and its Anlas actually buy, and AI Dungeon vs NovelAI sets the two side by side.
Talemate: the one that treats world state as a job
Talemate is the most interesting answer to the forgetting problem in the self-hosted half of this list. Its README describes it as “Roleplay with AI with a focus on strong narration and consistent world and game state tracking”, built on “Multiple agents for dialogue, narration, summarization, direction, editing, world state management, character/scenario creation”, with “Long-term memory and passage of time tracking” and “Narrative world state management to reinforce character and world truths” (github.com/vegu-ai/talemate, September 2026). It supports both commercial APIs and self-hosted backends including KoboldCpp.
That is the correct architecture for long campaigns, and it is open source. The cost is setup: you install it, you choose and pay for a backend, and you still author the world’s truths yourself before the agents can reinforce them.
Where a lore-grounded game master fits
The gap none of the above closes is the one a reader feels most: every one of them expects you to teach the software the world. Memory entries, story cards, lorebooks, world info, character truths — five names for the same evening of data entry, performed before the fun starts.
LLM RPG takes the other route. You upload a novel as .txt or .epub, it reads
the book and builds a searchable lore atlas from it, and the game master narrates
from that atlas while you play your own character inside the book’s world. The
canon is extracted rather than typed. You are shown the exact cost of reading a
book before anything is spent, and failed turns and unfinished extractions are
refunded automatically.
| Plan | Price | What you get |
|---|---|---|
| No account | free | A few turns in a ready-made world, no card |
| Free | free | 50 credits to start — a one-time welcome grant, about 50 turns |
| Pro Monthly | $9.00/month | 1,000 credits, about 1,000 turns, whole books |
| Premium Monthly | $29.00/month | 3,000 credits, about 1,000 turns narrated by our best model |
| Credit pack | $5.00 once | 400 credits, no subscription |
A narrated turn costs 1 credit on Free and Pro Monthly and 3 on Premium Monthly, and one credit reads 50,000 characters of a book into lore on every plan.
How to choose in one pass
- You want it free and private, and you have the hardware. KoboldCpp.
- You want to tune every prompt and already have a backend. SillyTavern.
- You want the best prose and are writing, not playing. NovelAI.
- You want agents tracking world state and do not mind installing things. Talemate.
- You want to play inside a book you have already read, tonight, with the lore handled for you. Start a run.
- You want the open scenario sandbox and the community library around it. Stay with AI Dungeon. Nothing here replaces that, and switching would cost you the part you like.
Switching without losing the story
Whatever you move to, the migration is the same three steps, and none of them are automatic:
- Export the story text from your current tool while you still have access. Plain text is the only format everything reads.
- Rebuild the world, not the transcript. Paste the last few hundred words as an opening and re-establish the facts — who is alive, what you carry, what you owe. Ten lines of state beats a full log every time.
- Start a new run rather than continuing the old one. A new narrator inheriting a half-remembered history produces exactly the drift you are leaving.
If money is the reason you are shopping, our breakdown of what AI Dungeon actually costs is dated and worth reading first — the free tier is more generous than the shopping-around instinct assumes. And if you want the wider category rather than replacements specifically, text-based RPG games worth playing covers it.
Prices, plans and feature claims about other products here were read from those products’ own pages and repositories in September 2026 and are dated for that reason; check them before you subscribe.
