A detailed reference for every field on the character creation form.
The name is your character's identity. It appears in search results, the marketplace, chat headers, and voice call screens. Keep it between 2 and 50 characters. Avoid special characters or excessive punctuation — clean names are easier to find and share.
The tagline is a short subtitle that appears directly below the name. It should be a single sentence (under 80 characters) that tells users what to expect. Think of it as the character's elevator pitch. Good taglines are specific and intriguing: "A Victorian ghost who haunts your grammar mistakes" beats "A helpful AI assistant" every time.
Both fields are indexed for search, so include relevant keywords naturally. If your character is a fitness coach, make sure "fitness" or "workout" appears in the name or tagline — don't rely on tags alone to surface your character in search results.
The description (also called the definition or system prompt) is the instruction set that shapes your character's behavior. This is the most important field on the form. It tells the AI who the character is, how it should speak, what it knows, and what it should avoid. See Chapter 3 for a deep dive on writing effective descriptions.
The greeting is the first message the character sends when a user opens a new chat. It's your character's first impression — the moment that decides whether a user keeps talking or bounces. A great greeting speaks in the character's voice, sets the scene, and invites the user to respond. Keep it between 1 and 4 paragraphs. Too short feels empty; too long feels like a wall of text the user has to read before they can participate.
One often-overlooked tip: the greeting also serves as a context anchor for the AI. The tone, vocabulary, and style of your greeting influence how the character speaks throughout the conversation. If your greeting is formal, the character will lean formal. If it's playful and casual, that energy carries forward. Make sure the greeting matches the personality you've defined.
The voice field lets you assign an audio voice to your character. This voice is used in voice calls and, where supported, in text-to-speech previews. You can choose from a library of preset voices or upload samples to create a custom cloned voice (see Chapter 7 for details on cloning).
When selecting a voice, consider your character's personality, age, and energy level. A mismatched voice — like a bubbly, high-pitched voice on a brooding noir detective — will break immersion instantly. Listen to the full preview, not just the first second. Pay attention to pacing, tone, and how the voice handles longer sentences.
Voice is optional. If you don't set one, users can still chat with your character via text. But characters with voices tend to see significantly higher engagement, especially for characters designed around companionship, storytelling, or education. If your character talks a lot, give it a voice.
Tags are keywords that help users discover your character. You can add up to 10 tags per character. Use a mix of broad and specific tags: a fantasy tavern keeper might use "fantasy," "tavern," "roleplay," "medieval," and "innkeeper." Tags are the primary driver of search discoverability, so choose them carefully.
When picking tags, think about what a user would type into the search bar if they were looking for a character like yours. Don't waste tags on generic words like "AI" or "chatbot" — every character is that. Focus on genre, theme, personality type, and use case.
Categories are broader groupings that organize characters on the marketplace. You'll select one primary category (e.g., "Entertainment," "Education," "Productivity," "Roleplay"). This determines which section your character appears in when users browse by category. Pick the one that most accurately represents your character's primary purpose.
Visibility controls who can see and interact with your character. There are three options:
You can change visibility at any time without losing chat history or user data. A common workflow is to create a character as private, test it thoroughly, switch to unlisted for feedback from friends, and then go public once you're confident in the quality.
Every character has a content type label that tells users what kind of interactions to expect. This helps users find characters appropriate for their preferences and helps the platform apply the right content policies.
The available content types include:
Choosing the right content type is important for two reasons. First, it determines which users can access your character — mature characters are age-gated. Second, it affects how the AI interprets your definition. A character marked as "General" will have stronger guardrails against mature content, while a "Mature" character has more latitude. Always be honest about your content type; mislabeling can result in the character being removed or re-classified.
