Hidden Door Cost: What's Free and What You Pay For
The short answer on Hidden Door cost is that the part most people want is free: as of late October 2026 Hidden Door’s own pricing page promises “unlimited play across the whole catalog, free”: every world, and chat with your characters “whenever you want”. There is now one paid plan, Creator, at $9.99 a month, and it is for making worlds rather than playing them: build a world from scratch, share or publish it, and get paid when people play it. That is the monthly price; the page also offers annual billing, marked “save 17%”.
That combination is unusual enough to be worth spelling out, because it changes what “cost” even means here. Most narrative AI tools ration the thing you do most: the turn. Hidden Door does not ration anything a player does. Its pricing page headline is the whole policy:
“Play every world. Enjoy unlimited play across the whole catalog, free. Upgrade to make and share worlds of your own.”
What the free Hidden Door plan includes
Taken from Hidden Door’s pricing page as read on 22 October 2026, in their own listing order. This is dated on purpose. Pricing pages move (this one has changed twice since September 2026), and it is client-rendered, so check it yourself before you commit.
| What you get free | The limit |
|---|---|
| Worlds from the catalog | Every one, “from Dracula’s castle to Oz and beyond” |
| Stories and turns | Unlimited |
| Chat with your characters | ”Whenever you want” |
| Playing as your own character | Included |
| Profile and achievements | Included |
Nothing a player does is metered. Their own FAQ explains the two units: a world is a setting and cast (“like Dracula’s castle or Oz”) and a story is a sequential adventure inside one, and you can play unlimited stories in each. Earlier versions of this page capped free players at five worlds and one character conversation a day; both caps are gone. The only reason to pay is to make worlds of your own.
The other thing worth catching is what happens if a Creator stops paying. Their FAQ says your worlds stay where you left them and remain available; you just cannot change them, share them, or receive payouts for them until you resubscribe. That is a meaningfully gentler cancellation than a tool that locks your library.
What the paid plan adds
This is the part that has moved most. In September 2026 the paid plan was a single tier called Atlas whose figure did not render for a signed-out visitor. In early October the page showed two plans, Fan at $7.99 and Creator at $19.99. By 22 October 2026 Fan was gone, its player perks folded into Free, and Creator had dropped to $9.99:
| Plan | Monthly price | What it gives |
|---|---|---|
| Free | $0 | Every world in the catalog, unlimited play, chat with your characters whenever you want |
| Creator | $9.99 / month | Everything in Free, plus creating a world from scratch, customising it, sharing or publishing it, getting paid when people play it, early access to new worlds, and creator support |
A few more things from their own copy worth knowing:
- Creator worlds can be published for everyone to play or kept friends-only, shared by link.
- Payouts follow their creator terms.
- Monthly and annual billing both exist; the annual toggle is marked “save 17%”, and switching from monthly to annual is prorated.
- Their FAQ says that if your partner-program application is accepted, Creator is free.
The price above is the monthly figure as rendered on the public page on 22 October 2026. Check the page before subscribing, especially for the annual figure.
Who should just stay on Hidden Door
Plenty of people, and it would be dishonest to write this any other way.
- You want to play, not to set anything up. The catalog is the product. Pick a world, pick modifier cards, go.
- You play a lot. Unlimited play across the whole catalog, free, is close to the best free deal in this category.
- You want to build worlds and be read. Publishing to a catalog where other people play what you made (and Hidden Door’s partnership program pays creators when others play their worlds) is something a private single-player tool structurally cannot offer.
- Fan-fiction energy is the point. Their own headline is “where role play meets fan fic”, and the catalog leans that way: remixing, crossovers, a duel of wits with Mr. Darcy in space.
If that is you, stop here. Nothing below is an argument that you are using the wrong thing.
When Hidden Door is the wrong shape
There is one reader Hidden Door does not serve, and it is a specific one: you just finished a particular novel, and you want to play in that book, not a world someone authored in its general direction.
Hidden Door’s worlds are hand-built, by the team or by creators, in “as little as 30 minutes” by their own description of world creation. That is a strength for range and a limit for fidelity: the world exists to the depth whoever built it went. If the book you want is not in the catalog, your options are to build it yourself from memory or to play something adjacent.
That gap is the job LLM RPG is built for. You upload the novel itself
(.txt or .epub), and it is read and turned into a searchable lore atlas
before you play, so the game master is answering from the book’s own text
rather than from a summary of its vibe. Then you play as your own character
inside it.
| Hidden Door | LLM RPG | |
|---|---|---|
| Where the world comes from | A catalog of authored worlds, plus ones you build | The novel you upload, read end to end |
| Turn allowance, free | Unlimited, every world in the catalog | 5 turns with no account; 50 credits (about 50 turns) once you sign up |
| Paid price, published? | $9.99/month (Creator, for making worlds), on the pricing page | $9.00/month (Pro) and $29.00/month (Premium), on the pricing page |
| Metering | None for players; you pay only to create | 1 credit per turn on Free and Pro; 3 on Premium |
| Publishing what you make | Yes, public or unlisted, with a creator program | No, private play |
| Best for | Playing and sharing authored worlds | Playing one specific book faithfully |
Read that table as two different products rather than a scoreboard. Hidden Door optimises for breadth and community; LLM RPG optimises for one book’s accuracy.
What LLM RPG costs, for comparison
Since this article is about what things cost, ours should be as legible as we are asking Hidden Door’s to be. As of September 2026, from our own pricing page:
| Plan | Price | What it gives |
|---|---|---|
| Free | $0 | 5 turns with no account, then a one-time 50-credit welcome grant (about 50 turns) and up to 5 credits of extraction on any single book |
| Pro Monthly | $9.00 / month | About 1,000 turns a month, whole books, no per-novel cap, rollover to 2,000 credits |
| Premium Monthly | $29.00 / month | About 1,000 turns a month narrated by our best game-master model, rollover to 6,000 credits |
| Top-up | $5.00 once | 400 credits, no subscription, never expire |
Two things we do that are worth knowing before you upload anything. You are shown the exact price of a book before a single credit is spent on reading it, and failed turns and unfinished extractions are refunded automatically. The opening scene of a run is free on Free and Pro.
How to decide in five minutes
- Search the Hidden Door catalog for the world you want. If it is there and it is good, you are done. Play it free, and the cost question may never come up for you at all.
- If it is not there, ask whether “in the spirit of it” is enough. For a lot of play, it is. Modifier cards and crossovers are genuinely fun on their own terms.
- If you want the actual book (its places, its minor characters, what happened in chapter nine), upload it instead. Play a free opening scene with no account and see whether the game master is reading or improvising.
- If you want to be read by other players, Hidden Door is the one with a catalog and a creator program. We do not have one.
Elsewhere on this blog: a SillyTavern alternative that writes the lorebook for you if you are coming from a configure-it-yourself setup, is AI Dungeon free for the same cost question asked of AI Dungeon, and games like AI Dungeon for the wider field.
The bottom line on Hidden Door cost: free is not a trial here, it is a real plan with unlimited play in every world, and a player never has to pay at all. You pay $9.99 a month (Creator) only when you want to build and publish worlds of your own.
