Is AI Dungeon Free? Yes — and Here's Exactly Where Free Stops

19 September 2026

Is AI Dungeon free? Yes — and that is AI Dungeon’s own description rather than a paraphrase of it. What the free account gives you is a real game with a real ceiling: no monthly credits, a 25-memory bank, and the basic set of features. Everything above that ceiling is a subscription running from $14.99 to $99.99 a month as of September 2026. The interesting question is therefore not whether it is free but where free stops — and whether that line falls before or after the thing you actually want to do.

This is the whole price list, taken from AI Dungeon’s own guidebook, plus what the free tier is genuinely good for and who should stop paying.

The short answer

• Free is a complete game, not a trial. A free account plays AI Dungeon with no time limit and no card, on any device.
• The first paid tier is $14.99/month (Journey), and the ladder climbs to $99.99/month (Ultimate) before you reach the separate Shadow Tiers.
• Free gets zero monthly credits and 25 memories. Paid tiers add more models, more context, more memories and a monthly credit bundle — those are the four things the subscription is buying.
• If you came here wondering whether free is enough to play through a book you love, that is a different question, and it is answered further down.

What the free account actually gets you

AI Dungeon’s guidebook answers the question directly, so it is worth quoting rather than interpreting:

“Yes, AI Dungeon is a free-to-play game, no matter what device you’re playing on! Your free account grants you access to all of AI Dungeon’s basic features.”

That is a stronger offer than the word “free” usually carries. There is no turn counter running out on you, no seven-day window, and the game is playable in a mobile browser at play.aidungeon.com if you would rather not install the app. Free trials of the paid tiers are also available, so the subscription side has its own try-before-you-buy route.

What free does not include is stated by omission in the same table. The free tier is listed as Wanderer, with 0 credits and a 25-memory bank, and the paid plans are summarised as adding “more AI text and image models, more context, more memories, and a bundle of Credits to use for image generation or temporary additional context.” Read that sentence carefully, because it names the four levers AI Dungeon sells: model choice, context length, memory, and credits. Free gives you the game; a subscription gives you more room inside it.

What each AI Dungeon tier costs

This is AI Dungeon’s own membership table, as published in their guidebook. It is dated because prices move:

Two details in their own copy are worth catching. Credits are metered per month rather than granted once, and their page notes that “each membership tier features customizable subscription lengths with discounts available” — so the monthly figures above are the sticker price, not necessarily what a longer commitment costs.

Notice the shape of the ladder, too. Memory roughly doubles as you climb, while the price roughly triples from Journey to Mythic. The jump from free to the first paid tier is also the single biggest one on the board, because free sits at zero credits rather than at some small allowance.

The trial, and the catch, in their words

AI Dungeon’s trial works differently from most subscriptions, and their guidebook says so plainly:

“When you sign up for an AI Dungeon subscription (specifically Champion and Legend tiers), we provide a one-week trial that lets you start using premium benefits before payment begins.”

“premium benefits end when a trial is canceled”

That second line is the one people miss. Cancelling during the trial ends the premium benefits immediately rather than letting you ride out the week you were given. Their page states the reason — per-user costs for premium models are far higher than for a conventional game — and offers a discretionary refund if you forget to cancel and stop playing. If you take the trial, take it on a week you intend to play.

One practical note from reading their own pages together: the trial page names the Champion and Legend tiers, while the current membership table lists Wanderer, Journey, Legend, Mythic and Ultimate. The tier list has been renamed since that page was written, so confirm which plan you are on when you sign up rather than assuming the trial page’s names still map one-to-one.

Shadow Tiers exist, and AI Dungeon itself says you do not want them

Above Ultimate there is a second ladder — Banshee, Reaper and Apocalypse — sold as Shadow Tiers. They are aimed at players who were buying individual credit packs repeatedly, and what they mostly sell is context: each tier roughly doubles the context window of the one below it, alongside more memories, more credits and cheaper image generation.

The unusual part is how their own page frames it:

“The prices of Shadow Tiers can be uncomfortable. It’s important to know that Shadow Tiers are not the right option for the average player—not even the above average player.”

That is refreshingly direct, and worth taking at face value. Shadow Tiers are web-only, monthly-only, with no annual discount, and they include a “Shadow Clan” that lets a member add other players at no extra cost. If you are asking whether AI Dungeon is free, none of this is your problem yet — but it is the ceiling the whole pricing system is arranged beneath.

Who should stay on the free account

Plenty of people, and it is worth being honest about which ones.

• You play in bursts and do not mind starting fresh. A 25-memory bank is enough for a short adventure, a one-shot scenario, or an evening’s messing about.
• You are deciding whether you like the format at all. Free is the correct way to answer that. No subscription tells you whether you enjoy AI-driven text adventure better than free does.
• You already treat AI Dungeon as a sandbox you dip into. Their free tier is unusually generous for a hosted AI product, precisely because the company keeps saying so.
• You want to build your own scenarios, prompts and scripts before paying. The authoring side is where AI Dungeon is strongest, and it is available to you at zero.

Stay on free, and feel no urgency about it. The subscription buys headroom, and headroom only matters once you have hit the wall.

Who should pay

• You are running one long campaign. That is what memory and context buy: the story keeps hold of what happened forty turns ago. This is the single clearest reason to upgrade.
• You want the better models and longer context. Model choice is a paid lever, and on the free tier it is not one you have.
• You generate images alongside the text. Credits are what pay for image generation, and free accounts get none per month.
• You want more than one story going. More memories means more threads held at once.

If two or more of those describe you, Journey at $14.99 is the tier to look at first — it is the cheapest step that adds monthly credits at all.

If what you want is to play inside a book you have already read

There is a specific reader who arrives at “is AI Dungeon free” with a hidden second question: can I use this to keep living in a novel I have just finished? AI Dungeon can host that, and people do it — but it is not what the product is built around, and the free tier is the worst place to find out, because the credit ceiling lands exactly on the work of getting a whole book’s worth of detail into the story.

LLM RPG is built for that reader and nothing else. You give it the book — a .txt or an .epub — and it reads the whole thing before you play, building a searchable atlas of its characters, factions, locations, items and events. You then play as your own character rather than as one of the book’s, narrated by a game master that queries that atlas instead of improvising, with a referee settling what your character can actually pull off. If you have no book to hand, there are ready-made worlds with their lore already built.

The comparison that matters to a free-tier reader is this one:

The honest trade: AI Dungeon’s free tier is wider; LLM RPG’s free tier is deeper on one narrow job. If you want an open sandbox with no ceiling on turns, free AI Dungeon is the better deal and you should keep it. If what you want is a specific book turned into a world that stays consistent, the free allowance here is aimed at exactly that — and you can test it without deciding anything, because five turns are free with no account and no card.

The honest summary

AI Dungeon is free in the way that matters: you can play it indefinitely without paying, on any device, with the basic feature set intact. What costs money is room — monthly credits, memory, context and model choice — and the first paid tier at $14.99/month is where all four arrive at once.

So the answer to the question depends on which one you were asking:

• Can I play AI Dungeon without paying? Yes, indefinitely and properly.
• Is the free tier enough for a long, memory-heavy campaign? No, and it is not pretending to be — 25 memories is where that ends.
• Is free enough to play inside a novel I love? That is a different job, and the five free turns here will tell you more about it in ten minutes than another pricing table will.
