Disclosure first: I built the thing I'm about to describe, so weigh everything accordingly. I make The Endlessness, a solo D&D 5e game with an AI DM that follows the actual rules. Dice rolled in the open, spell slots enforced, the world remembers what you did last session. It just gained a feature that I suspect matters more to this sub than to anyone else, so I came here to share it.

You can upload your own adventure, the draft PDF, the DOCX, the zip of loose notes, and it reads what you wrote and builds a private, playable world out of it. Your locations, your NPCs, your factions, your quests. Then you roll a character and walk through your own adventure as a player.

The reason I think this belongs here: an adventure reads one way and plays another, and no amount of rereading closes that gap. Does the opening hook actually hook? Is there enough for players to find in act two, or does it sag? Is the clue you think is obvious actually findable? Those answers only exist at a table, and a table is the one thing a work in progress almost never gets. Playing your own draft is humbling in a very specific, very useful way.

Honest limits so nobody is surprised. It runs everything as 5e, whatever you wrote for. It's an adaptation, not a recital: it keeps your places, people, and plot, and improvises connective tissue the way a human DM runs a module they've read but don't have memorized. And it builds a sharper world from drafts that say what things are, even in one line. Notes that open with "Karvos is a port city held by the Ashen League" give it far more to work with than notes that assume the reader already knows, and half-finished drafts always assume the reader already knows.

The business part, said plainly: uploads are on the paid plans, one or three imports a month at $9.99/$24.99, because reading a whole document is the most expensive thing the game does. The free tier is the full game on the built-in worlds, 20 turns a day, no card, and it's the right way to decide whether the DM is good enough to be trusted with your draft before you pay anything. And this goes without saying: your draft is private to you and never shared with any other player or even with us. It lives on your account only.

If you run a work in progress through it, I genuinely want to hear what it got wrong about your adventure. That's the feedback that shapes where this goes!
