AI Character Card Generator

A good character card is the difference between an AI that holds a believable persona and one that dissolves into a generic chatbot by the second exchange — but writing one from a blank field is the part most people stall on. This tool rolls a complete starting card for you in a click: pick a few constraints, hit Generate, and you get a coherent character with a personality, a scene to meet them in, an opening message, and example dialogue — formatted to paste straight into Janitor AI, SillyTavern, or any platform that reads the character-card format.

It's a generator, not a chatbot: no AI is called, nothing is sent anywhere, and the result is assembled instantly in your browser from curated content. Each roll combines an archetype's core voice with independently sampled quirks, speech patterns, flaws, motivations, and scenarios, so re-rolling gives you genuinely different characters. Treat every result as a strong first draft — then make it yours. If you want to understand why each field matters before you start editing, read how to write a character card.

Set your constraints — or leave them on Any and roll

How to Use Your Generated Card

The card you get is a coherent starting point, not a finished character. The fastest way to make it sing is to do exactly what good card authors do: get specific. Swap the sampled quirks for ones that mean something to your story, sharpen the first message so it sets the exact tone and length you want back, and rewrite the example dialogue in the character's real voice — that single field shapes how the AI talks more than any other. Our guide on how to write a character card walks through why each part carries the weight it does.

To use it, open a new character on your platform of choice and paste the fields across. On Janitor AI, the personality, scenario, first message, and example-dialogue boxes map directly onto the card's sections. On SillyTavern, the same fields drop into the character editor, where you get finer control over how the card is injected and can attach a lorebook for deeper world detail. The {{char}} and {{user}} macros in the card are standard on both — they're swapped for the character's name and yours automatically.

Whichever platform you land on, the character will only hold up for as long as the model can keep the card in view — the same context-window limit that makes every long AI session eventually drift, covered in why LLMs forget. For a campaign you want to run over weeks, the free Campaign Memory Tool tracks your canonical state alongside any front-end, and the AI RPG Prompt Builder generates a full system prompt if you want a whole game around your character rather than a single chat.

And if what you really want is a designed world with rules, stakes, and persistent state — not one character but a complete system — the Arcanum Originals are free, fully-engineered RPG engines you run inside ChatGPT, Claude, or Gemini. A generated card is a great companion; an Original is the whole game.
