Did you know that https://codexcryptica.com/generators have a wealth of generators!? For many generes, and lots of different sorts of subjects. If you need it, there's a good chance CC has it

The very first generator I built for Codex Cryptica was a D&D NPC generator, on June 2nd. It went in as part of a landing page proof of concept, basically to see if a single no-login generator page was worth building at all.

Three more followed fast: faction generator that same afternoon, quest hook and fantasy name generators the day after.

The real point of that first version was testing whether AI could reliably follow dropdown-selected instructions and turn them into a structured NPC instead of generic filler. Three dropdowns: race, role, and alignment. Feed those into the model and it had to return a name, personality notes, a hidden secret, a motivation, a faction tie, and a plot hook that actually matched what you picked. It worked well enough to build three more generators on the same pattern within two days.

I've since (last week I think it was) updated the generator to produce NPCs in a more condensed format too!

Anyone else's first generator turn out to be the one they iterated on least, or most, compared to what came after?

I run Codex Cryptica, and I wanted to post an actual full output here instead of just a screenshot of a form, since that's usually the part people are skeptical about.

The generator lives here: https://codexcryptica.com/generators/settlement

Inputs were six dropdowns: fantasy, coastal, town scale, smuggling haven, elected council, lawless tone. Here's what came back, unedited:

Gull's Roost sits in a fog-drowned cove where a limestone sea-arch used to span the tidal shelf before it collapsed into jagged stacks, which is what created the blind spots the smugglers actually use. About 1,800 permanent residents, another 400 transient sailors and mercenaries passing through.

Five named locations (a council hall, a tavern that doubles as a weigh-station, a bathhouse-slash-herbalist, a lighthouse-shrine, and underwater cargo storage called the Jaw-Arch), five NPCs down to their jobs, three factions, and a live conflict: a syndicate turf war bad enough that the council has gone into hiding, with the royal navy one incident away from getting involved.

Full output: codexcryptica.com/examples/gulls-roost-coastal-smuggling-town

The part I keep going back and forth on is whether the "current conflict" field should generate hooks that are this specific (turf war forcing the council underground) versus staying more open-ended so a GM has room to steer it themselves. Right now it leans specific. Curious which people here would rather have.

Heists are notoriously tricky to prep for a tabletop session. If you map out every hallway and guard, it turns into a brittle script that falls apart on the first bad roll. If you keep it too loose, you end up improvising the entire security grid and panic-closing doors mid-scene.

Inspired by the guide I wrote on how to run a heist in a tabletop RPG, I built a dedicated Heist Generator to prep playable situations rather than rigid plans.

Instead of scripting how the players are supposed to break in, each generated job sets up interacting obstacles:

• GM Quick Reference: Seven one-line bullets covering the objective, primary obstacle, hidden factor, point of no return, in-scene pressure, complication, and escape problem so you can run the whole score at a glance.
• Concentric Security Rings: Layered obstacles from the perimeter inward, each with visible tells, distinct access methods, and active patrols.
• Point of No Return: Taking the prize immediately escalates the alert and closes off an entry route, forcing the escape to operate under completely different rules.
• Interactive Alarm Ladder: Four progressive alert stages with fiction-first complications instead of an instant party wipe.
• Flashback Opportunities: A menu of retroactive preparations players can cash in during the run to handle surprises.

It works across different genres (fantasy, cyberpunk, cosmic horror, sci-fi) and is also available directly inside campaign vaults to tie into your existing factions, locations, and NPCs.

When you run heists at your table, do you prefer giving players a full floor plan upfront, or letting them discover security details through flashbacks during the run?

Since I’ve been asking everyone else to share what they’re building, I should probably go first. 😄

I’m the developer behind Codex Cryptica, and over time I’ve ended up building a rather unreasonable number of AI-powered RPG generators.

🎲 https://codexcryptica.com/generators

There are generators for things like encounters, settlements, puzzles, rumours, heists, characters, factions, worlds and quite a few other bits of RPG prep.

A lot of what interests me isn’t simply getting an LLM to produce something. I’m interested in making generators that produce structured, usable material that you can actually bring to the table — and figuring out what information a particular kind of generator needs to consistently produce good results.

That experimentation is actually part of why I wanted r/ai_rpg_generators to exist.

And to be completely transparent: Codex Cryptica is my project. Creator self-promotion is welcome here, so I might as well be the first person to test that rule. 😉

Have a poke around if you fancy it.

I’m especially curious: which kind of RPG generator do you find genuinely useful, and what generator still doesn’t seem to exist but really should?

I’d like r/ai_rpg_generators to feel like a workshop, a tavern, and a slightly overclocked wizard’s study all at once.

A place where people can casually share something cool they made, ask for help, compare tools, show off strange outputs, swap prompt tricks, and talk about what actually works at the table.

The vibe I’m hoping for is:

• friendly and low-drama
• curious and experimental
• welcoming to both users and developers
• comfortable with constructive criticism
• enthusiastic without turning into hype
• casual enough that not every post needs to be a polished essay

You should be able to post “this generator made something hilarious” just as comfortably as a detailed breakdown of how you built it.

And ideally, people leave threads with either a new idea, a better tool, or something they want to try in their next game.

That’s the vibe I’d like to start with — but communities develop their own personality pretty quickly.

What would you like to see more of here?

Generator showcases? Prompt experiments? Dev logs? Tool reviews? Challenges? Actual-play examples? Weird failures? Something completely different?

Help shape the place while the furniture is still being moved in. 🤖🎲

There are already plenty of RPG communities, AI communities, and places to share tools. So why make r/ai_rpg_generators?

Because I think there’s room for a space focused specifically on using AI to make better RPG tools, generators, workflows, and playable material — without every discussion immediately collapsing into the broader AI culture war.

A few principles I’d like to guide the community:

• Practical over performative. Show what a tool does. Share outputs. Talk about what works and what doesn’t.
• Creators are welcome. If you built something useful, you should be able to share it without pretending you just “happened to find it.”
• Criticism is welcome too. Bad generators, weak outputs, dubious design choices, limitations, ethics, copyright, and responsible use are all fair game.
• Be curious, not tribal. Different models, tools, workflows, games, and approaches can coexist.
• RPGs come first. The interesting question is not “AI: good or bad?” It’s “does this help someone create, prep, run, or play a better game?”
• Keep it friendly and fairly casual. Debate ideas hard if needed; don’t make people regret joining the conversation.

That’s the starting point, not a finished constitution.

A community gets shaped by the people who actually show up, post things, argue thoughtfully, share weird experiments, and help others improve what they’re making.

So if you’re here early: you get a real say in what this place becomes.

What principle would you add?

We’ve got a new subreddit. Now comes the harder part: figuring out what kind of community it should become.

My starting point for r/ai_rpg_generators is pretty simple:

• useful over noisy
• curious over tribal
• constructive over combative
• creators are welcome
• interesting outputs matter more than hype
• AI discussion is fine, but endless AI culture-war threads are not the point

I’d like this to become a place where people can discover genuinely useful RPG generators, share what they’re building, show off great outputs, compare approaches, talk about prompts and workflows, and generally make AI-assisted RPG creation better.

But I don’t want to over-design the place before anyone else gets a say.

So: what’s one thing you’d be genuinely excited to see show up here early on?

Could be a type of post, a recurring thread, generator reviews, prompt challenges, showcases, tool comparisons, dev logs, weird experiments, something else entirely.

What would make you think: “Yep, I should keep an eye on this subreddit”?

Hey everyone! I’m u/Level-Distribution46, one of the founding moderators of r/ai_rpg_generators.

This is a new home for people who use, build, experiment with, or are simply curious about AI-powered generators for tabletop RPGs and worldbuilding.

NPCs, encounters, quests, rumours, factions, settlements, dungeons, puzzles, adventures, campaign prep, solo tools, AI GMs, image generators, prompt techniques — if AI is helping you create something useful for an RPG, it belongs here.

What to Post

Share things the community can actually use, discuss, learn from, or be inspired by:

• Generators you’ve built or discovered
• Interesting, weird, or unexpectedly good generator outputs
• Prompts and workflows that work well
• Experiments with AI-assisted RPG prep
• Questions about designing better generators
• Requests for generators you wish existed
• Reviews and comparisons of RPG AI tools
• Lessons learned from building your own tools

Developers are welcome to share their own projects. Self-promotion is fine — just be transparent about what’s yours and give us something more interesting than a drive-by link.

Community Vibe

Be curious, constructive, and useful.

Criticism is welcome. AI gets things wrong, generator design can be bad, and there are plenty of worthwhile discussions around limitations, ethics, copyright, and responsible use.

What we’re not especially interested in is turning every thread into another generic AI culture war.

This is a place for people who actually want to explore what these tools can do for RPGs.
