Love the AI storytelling. Tired of the AI deciding the dice.
AI Dungeon is genuinely great at freeform improv. The catch is structural: the dice live inside the AI's text, so a crit, a death save, or a saving throw is whatever the model writes. LoomMaster keeps the living, reactive AI narration - and hands the dice to a real D&D 5e engine that cannot be fudged.
Engine-first, not chatbot-first.
In AI Dungeon the model improvises everything, the dice included. That is perfect for anything-goes storytelling, but it means the rules are a vibe, not a system - the AI can quietly write you a hit, forget a condition, or soften a death save without anyone knowing.
LoomMaster inverts it. A real D&D 5e rules engine rolls and validates every die on the server and writes it to a tamper-evident ledger before a single word of narration exists. The AI is a brilliant narrator wrapped around an honest engine - never the thing deciding whether you hit. You can even mint a public Loom Seal that lets anyone re-verify every natural d20 your campaign rolled.
Everything you actually liked about AI Dungeon.
A living AI that reacts to anything you type, in plain language. Go off the rails, talk to anyone, try the thing the module never planned for - the Director rolls with it. No menus, no scripted choose-your-own-adventure rails. It still feels like an imagination engine, not a form.
And it remembers. Persistent server-side memory means the innkeeper recalls the favor you did five sessions ago and the rival you crossed is still carrying it - the continuity long AI Dungeon stories tend to lose as context drifts.
The rules become real.
Full 5e, enforced mechanically: spell slots, save DCs, the action economy, conditions, the death-save ladder, real critical hits. A nat 20 is a nat 20 because an engine rolled it, not because the story needed one. The AI cannot write your character's actions or words either - that is a hard line in the routing layer, so your agency is never overwritten.
It is also provable. The deterministic core is source-available and externally audited - one engine that runs byte-identically across implementations - so "the dice are honest" is something you can check, not a tagline you have to trust.
Stay with AI Dungeon if...
...you want pure, rules-free sandbox fiction where literally anything can happen and the numbers never need to mean anything. That is a real preference and AI Dungeon is excellent at it. We are not trying to be that.
Switch to LoomMaster if you came from a real 5e table and want a critical hit to be a real critical hit, a death save to actually matter, and a Game Master who cannot quietly save you or sink you. That is the whole reason the engine, not the AI, owns the dice.
