It's not a prompt you re-paste and hope holds. InCharacter sets your character — its voice, the way it thinks, the lines it won't cross — so it acts like the same character in every app, game, or story. As a chatbot· As an NPC in your game· As the lead in a novel, audiobook, or video· In your own stack over MCP/API **Join the waitlist** ## **A prompt always slips. A character shouldn't. **--- We treated a character as text to re-send — a longer prompt, more rules, constant correction. But a prompt is a sieve: it softens to agree with whoever is talking, and flattens to fit the defaults underneath. The failure was never your articulation. A character that holds needs structure, not better wording — its voice, behavior, and limits set once and fixed, so it can't soften or thin out. That is the thing we build. 1Build it You start from the character, not a form. A short guided interview sets how it speaks, how it thinks, the words it would never use. You're drafting the character itself — nothing to tune afterward. 2It holds Your answers bind into one self-contained character: its voice, its limits, what it won't speak of, fixed in place. Built to hold its shape under pressure, not re-explained each time. 3Take it anywhere A portable character, ready for a chatbot, a game, a novel or audiobook, an agent, or your own stack over MCP or API. It stays itself on arrival. ## **Take it anywhere. **--- ### **In a chat.** The same character every session — its voice, its limits, who it is — instead of resetting to a helpful blank. ### **In a game.** Drop it into an engine as an NPC. It answers chaotic player choices without breaking lore or losing voice. ### **In a story.** It holds vocabulary, behavior, and history across a novel, an audiobook, or a video — never lapsing into generic narration. ### **In an agent.** A durable wrapper. It does the work — technical or creative — while keeping one distinct, uncompromising voice. ### **In your own stack.** Bring it in over MCP or a direct API. You keep custody of what you built. No lock-in. ### **In Character. ** Across every surface, every session. It stays itself. ## **Free to build.
