The AI Roleplay Glossary: Every Term, Explained in Plain Language

Stories you can play right now

The AI roleplay world speaks a dialect assembled from fanfic culture, tabletop gaming, and machine learning papers. This is the decoder ring — plain-language definitions, alphabetical-ish, opinionated where it helps.

Character terms

  • OC (Original Character): a character you invented, as opposed to one from an existing fandom. OCs are the safest and most rewarding thing to publish — on platforms with creator earnings (like ours), they're the only monetizable kind.
  • Character card / sheet: the structured definition of a character — personality, voice, backstory, example dialogue — that the AI performs from. Card quality determines roleplay quality more than model choice does.
  • Persona: the character you play as; your side of the sheet.
  • Headcanon: a personal belief about a character not stated in canon. We built a generator for these.

Play terms

  • RP / roleplay: collaboratively acting out characters in a scenario, in turns.
  • OOC (out of character): speaking as yourself, usually in brackets — "(ooc: let's skip to the festival)". The universal control channel.
  • Slow-burn: romance paced across many chapters instead of message twelve. Requires memory and structure; the whole argument of our romantic AI guide.
  • Ships / shipping: rooting for (or engineering) a relationship between characters.
  • Lorebook / world info: a reference the AI consults so facts stay consistent — kingdom names, magic rules, who's secretly a vampire.

Machine terms

  • Token: the unit AI models read and generate text in — roughly ¾ of a word. Pricing and memory limits are measured in tokens. Full explainer →
  • Context window: how much recent conversation the model can "see." When a scene exceeds it, older details fall out — the technical root of AI amnesia. Platforms fight this with summaries and structured memory.
  • Model: the underlying AI (different vendors, different writing personalities). Most chat apps lock you to one; some (ours included) let you switch mid-story.
  • Temperature: a randomness dial — low is focused and repetitive, high is creative and chaotic.
  • Filter: platform-level content restrictions. The single most argued-about word in the hobby; approaches range from strict global filters to rated, age-gated tiers to bring-your-own-model freedom. The landscape →
  • Jailbreak: prompt tricks to evade a filter. Against most platforms' terms; mostly a symptom of filter-model mismatch.

Format terms

  • Visual novel (VN): story presentation with character art, backgrounds, and music over the text — the format our storylines borrow.
  • Greentext: the "be me" story format from imageboards. Generator here.
  • Isekai: the another-world genre. Full explainer →

Missing a term you've seen in the wild? It probably means someone's about to explain their lorebook to you. Good luck — and if you'd rather play than study, the practical exam is free.
