AI Dungeon Master & RPG Fablia screenshots
The pitch that stands out to me with Fablia is simple: an AI dungeon master that answers whatever you type. There is no group to assemble and no rulebook to learn first, because the developer's idea is that you describe an action and the narration comes back to you. That single loop is the whole product, and it is a promising one for anyone who has wanted to play a fantasy campaign on their own schedule.
That makes it a fit for people who already enjoy tabletop roleplaying, interactive fiction, text adventures or choose-your-own-adventure books but rarely get a table together. It is also aimed at players who like the idea of writing their own character rather than picking a class from a menu. The app is free to install, carries no ads, and offers in-app purchases; it holds a 4.6 average from 2,284 ratings at more than 10,000 installs, which suggests the core loop lands with the people who try it.
A dungeon master on call, not a scripted campaign
The premise is a fantasy RPG built around your choices rather than a fixed storyline. You say what your character attempts, and the app writes the outcome, whether that means talking your way past gate guards, setting a tavern alight, sparing a bandit, or abandoning the quest altogether. The developer promises the story bends around your decision and remembers it later.
What I like about that framing is the absence of a branching menu. You type freely instead of tapping preset replies, so the range of plausible actions is limited mainly by your imagination and by how well the narration keeps up. Nothing is scripted, according to the developer, and no two runs are meant to tell the same tale.
The setting is broad fantasy: ruined keeps, drowned shrines, bargains, bluffs and threats, companions you recruit and can lose. You can start as a knight who keeps an oath or one who breaks it, a scheming merchant, a hedge witch, a deserter or a god-touched fool. Your written character drives the roleplay, not a preset class.
Two ways to start a campaign
Fablia offers Quick Play and Custom Game as entry points. Quick Play skips the setup: pick a character and a story, then begin. That is the option I would expect most people to reach for when they want to start playing without much setup.
Custom Game goes considerably further. You write the story, the rules and the world, down to its laws, its key people and how the dungeon master should run it. That last part is the interesting one, because it means the narration style itself is something you can shape rather than something fixed by the app.
Between the two, the app covers both an evening's quick session and a longer project. If you have ever wanted to run a world of your own design without doing the bookkeeping a tabletop game usually demands, Custom Game is the part of Fablia that speaks to that.
Dice, death saves and the weight of a bad roll
Checks use a 3D D20 roll with sound and haptics, the way a table would handle it. Clear the target number and your hero stands; fall short and luck runs out. Overreach, and a death save follows.
That mechanic matters because it puts a limit on how much the narration can simply bend to your wishes. You can attempt almost anything you can describe, but the dice decide whether it works, which keeps outcomes tense in a way that pure improv storytelling often is not. It also gives the app a genuine tabletop feel rather than the sense of reading a novel that occasionally asks for input.
The dice are also where the app's presentation does some work. A 3D roll with sound and haptics is a small thing, but it is the moment in a session when the outcome is decided, and treating it as an event rather than a line of text is the right call.
What you carry between sessions
Fablia keeps a record of your campaign in several forms. A character sheet tracks stats, skills and gear. A codex records the lore, characters and locations you discover along the way. Every scene goes into a chronicle, and save slots let more than one adventure continue at once.
I would expect the codex and the chronicle to be the parts that reward longer play. In a game where the story is generated around your decisions, having a written record of who you met and what you did is what turns a series of sessions into a campaign you can look back on. The save slots matter for the same reason: you can keep a serious run going while starting something looser alongside it.
The character sheet is the quieter piece of bookkeeping that makes the rest work. Stats, skills and gear give the dice rolls something to draw on, so the numbers you build up over time have a bearing on what your hero can realistically attempt.
Session length, voice and what the updates add
The developer pitches Fablia as a solo RPG for sessions of five minutes or five hours, which fits the structure: one typed action and its narration make a natural short session, while the chronicle and save slots support something much longer. That flexibility is a large part of the appeal for anyone whose free time comes in unpredictable blocks.
A few recent additions are worth knowing about. Signing in with Google keeps your games, Gems and subscription available across phones. Live Mode lets you talk to your dungeon master by voice, and Listen adds read-along word highlighting. European Portuguese joins the supported languages, and the notes also mention surveys in Bounties and general fixes.
Gems and a subscription are referenced in those notes, which lines up with the app offering in-app purchases. The install is free and there are no ads, so any spending sits alongside the game rather than interrupting it.
What the free download and the purchases mean
Fablia costs nothing to install, shows no ads, and includes in-app purchases. There are Gems and a subscription.
The practical point for anyone weighing it up is that you can start a campaign without paying anything and see whether the AI dungeon master's narration suits your taste. That is the part of the app everything else depends on, and it is the part worth forming your own opinion about before deciding whether the paid elements are worth adding.
It is not a guarantee of anything for you in particular, but it is a better starting point than an app with no track record at all.
A solo RPG for players who would rather type than tap
Fablia is at its most appealing if you want fantasy roleplaying that starts the moment the mood strikes, without arranging a group or learning a ruleset first. The typed-action loop, the D20 checks and the codex together make something that reads like a tabletop session compressed into a phone, and the Custom Game option gives you room to define the world and the narration yourself.
It suits people who enjoy writing their own character and are happy for the dice to have a real say in how things turn out. It is also a natural fit for anyone who has bounced off branching-menu story games and wants to describe their own actions instead of choosing from a list.
The app is free to install with no ads and optional purchases, so trying a campaign costs you nothing but time. If the idea of a dungeon master who never runs out of story sounds like the gap in your gaming life, this is a sensible place to start.
The short verdict
A free, ad-free solo fantasy RPG that turns typed actions into a running campaign, with D20 checks and a codex to keep.

AI Dungeon Master & RPG Fablia: frequently asked questions
How does a game of Fablia actually play out?
You describe what your hero does and the AI dungeon master narrates what happens next, so the story bends around your choice rather than a branching menu. Skill checks are resolved with a D20 roll, and beating the target keeps your hero on their feet while missing it turns fortune against you. Push too far and you face a death save.
What is the difference between Quick Play and Custom Game?
Custom Game is the fuller option: you write the story, the rules and the world, including its laws, the people who matter and how the dungeon master should run it. Custom Game is the route to take if you want to shape the narration as well as the setting.
Does Fablia keep a record of my campaign?
Yes. A character sheet tracks your stats, skills and gear, a codex records the lore, characters and locations you discover, and a chronicle logs every scene. Multiple save slots let you run several adventures side by side, so a long campaign and a shorter one can coexist.
What does Fablia cost, and are there ads?
The app is free to install and shows no ads, and it offers in-app purchases. There are Gems and a subscription. You can begin a campaign without paying anything and judge the narration for yourself first.

The most recent notes cover Google sign-in so your games, Gems and subscription follow you between phones, plus Live Mode for talking to your dungeon master by voice.
