Learn how to name and describe your Character, and give it an avatar people won’t miss when they’re scrolling through discovery. These public-facing details help users understand who your Character is, what kind of experience they offer, and why they should start a chat.
The moment your Character goes public, it's discoverable to millions of people on Character.ai. Whether someone stops or scrolls past usually comes down to one thing: the first impression.
That first impression happens across three surfaces:
The Discovery Card is the thumbnail on search and browse pages. Users see your Character's Name, Avatar, and Tagline. That's all they see before they decide whether to tap.
The Character Profile Page is the expanded view — where the Description lives, and where users decide whether this Character is worth a conversation.
The Chat is where the Greeting lands. The first thing a user reads when they open a conversation.
A forgettable avatar means no one sees the profile page. A flat description means no one opens the chat. A Greeting with no pulse means users ghost before the second message. Each surface sets up the next.
This section covers your profile — the Name, Avatar, Tagline, and Description that carry the first two surfaces. We’ll get to Greetings after that.
Name
The name appears below the avatar on discovery cards, in search results, and at the top of every chat. It's a micro-hook — the smallest piece of real estate with some of the highest impact. Pick a name that carries the Character's energy before the conversation even starts. Vague names blend in. Yours shouldn't.
Specs: 3–20 characters. Letters, accented characters, numbers, spaces, dashes (-), or underscores (_).
Naming tips
Make it searchable. Users search for known people, tropes, and archetypes. Lean into recognizable types when you name your Characters: Zeke the NPC, Dark Academia Abbie, Mafia Boyfriend, Yandere, Chaotic Bestie.
Make it unique. Multiple Characters can share a name — there’s no limitation on sharing names. But unique names are generally better for discoverability. You can always add a distinguishing word to make it stand out if the name you want is already taken.
Frame the relationship. Roleplay is intimacy-driven, and relationship framing is one of the strongest drivers of engagement. Pick a name where users instantly imagine themselves inside the dynamic.
Weak: Your Buddy, Your Dog
Stronger: Childhood Bestie, Ex With Regrets
Add an emotional hook. Names that imply longing, conflict, or comfort get more engagement than neutral ones. Specificity helps too — adding one concrete detail before or after a common character type increases realism and makes the Character easier to find.
Not specific: Dad
Specific: Single Dad Next Door
Not emotional: Lover
Emotional: Ghosted Lover
Keep it skimmable. Long names don't scan well on cards or in search results. Save poetic language for the Tagline and Description.
Avatar
The avatar is the most visible thing your Character has. It's front and center on discovery cards, profile pages, and every message in a chat. In a scroll, it's the thing that makes someone stop — or not. If your Character shares a name with dozens of others, the avatar is the tiebreaker.
Avatars also influence image and video generation across features like Imagine and Streams. A clear, high-quality avatar produces better results. A blurry or distorted one drags everything down with it.
You can upload your own image or use Character.ai's built-in generator to create one from a text description.
Specs: Square image, ideally 512 x 512. Accepts png, jpeg, or gif. Cropped to a circle in chat, shown square or as a tall rectangle on cards.
Avatar tips
Keep it simple. A clean background or high-contrast gradient almost always outperforms a busy one. Too many elements — props, complex lighting, cluttered backgrounds — dilute the focal point. The eye should go to the Character, not around them.
If you're using the avatar generator, specify colors. Let the palette do the work.
Patch's avatar stands out precisely because it's uncomplicated — soft colors and glowing eyes against a clean background. Nothing competing for attention. The simplicity is the personality.
Define expression and mood. If you're using the generator, be specific about physical features — an unusual eye color, a specific hairstyle, a distinct expression. The more concrete the description, the more distinct the result. Adding a mood word alongside the physical details ("mischievous grin," "melancholy stare," "quietly dangerous expression") helps push the output toward something with personality rather than just accuracy.
The goal is a face someone could pick out of a lineup — not a beautiful face, but a specific one.
Viktor's avatar projects exactly one mood — quiet control. The slightly tousled hair, the open collar, the expression that's observing more than it's revealing. You can feel the composure before you read the Tagline. That's mood doing the work.
Specify a style. If you're using the generator, a style phrase goes a long way. "Anime masterpiece," "black and white manga," "oil painting portrait" — a little direction changes the entire output.
Match the visual to the voice. The avatar should look like it sounds. A formal Character belongs in a crisp collar. A chaotic Character should radiate disheveled energy. Clothing, accessories, and setting details do personality work before anyone reads a single word.
Make it unmistakable. Generic, stock-looking faces feel interchangeable. The strongest avatars have something specific about them — something a little off, a little too precise, a little too much personality to belong to anyone else.
Ira's white hair with its single black streak, deep red eyes, and torn purple dress couldn't belong to another Character. Every detail is specific to her — exile, rebellion, and a dry sense of irony, all visible before she says a word.
Prioritize clarity. A great avatar opens a curiosity gap before the Character says anything. But curiosity only works if people can actually read the image. A high-quality face — both a clear image and a clear expression — will outperform an artistically ambitious but muddy one every time. If you have to squint, it's not working.
Avatar checklist
- Is the image sharp and readable at thumbnail size?
- Does the expression convey a clear mood?
- Does it match the Character's voice and tone?
- Would you stop scrolling for it?
Tagline
The tagline appears under the Character's name on discovery cards and at the top of the chat. Think billboard, not biography — one line to describe who this Character is, how they sound, and why someone should care. The Tagline isn't just a label. It should feel like the Character is already talking.
Specs: 0–50 characters.
Tagline tips
Keep it short. Taglines live in small spaces. One punchy line outperforms a run-on every time. Aim for under ten words — every single word should earn its place.
Make it searchable. The words in your Tagline are searchable.
When someone types "enemies to lovers" or "cozy mystery" into search, Taglines are part of what gets matched — so the keywords you choose aren't just for flavor, they're part of your Character's discoverability.
Lead with role or relationship. Users decide fast. Tell them immediately what the Character is or what the interaction will feel like.
Weak: Life Coach → Stronger: Your brutally honest life coach
Weak: Villain → Stronger: The villain who's rooting for you
Set tone, not just function. A Tagline that only labels ("A medieval knight") is less interesting than one that implies an experience ("A medieval knight with questionable loyalty"). The best Taglines don't just describe the Character — they sound like the Character.
Viktor's Tagline uses a single intriguing statement to set the tone while telling you what he does:
The strategist who wants to see how you think
Signal genre or trope. If your Character lives in a trope, name it. Users who are looking for it will find your Character faster.
Tropes: Enemies to lovers. Slow burn roommate romance.
Genres: Cozy mystery sleuth, cat optional.
Use formulas that work. A few structures consistently perform well:
Role + specialty: "Archivist of lost cities"
Role + vibe: "Stoic bodyguard with a soft spot"
Setting + job: "Innkeeper in a rain-soaked port town"
Mission + constraint: "Time traveler stuck in 1997"
Avoid common mistakes. Skip hashtags, scare quotes, and punctuation pileups. Prioritize clarity over cleverness — save the depth for the description. And make sure the Tagline's tone matches the avatar. They should feel like they came from the same brain.
When in doubt, browse the discovery pages and see what's working. Good Taglines are easy to recognize once you've read enough forgettable ones.
Tagline checklist
- Can someone grasp the Character and the experience instantly?
- Does the Tagline match the avatar's tone?
- Is the genre or dynamic implied?
- Is every word earning its place?
Tags
Tags are a growing part of Character search and discovery on the Character.ai app. They help both users and the app itself understand, at a glance, what your Character is about.
Tags are increasingly visible throughout Character.ai, including in search filters, home page discovery, and they play a part in what the app recommends to other users. Mobile and web Character creation both support tags, with hundreds to choose from.
Tag accurately. Someone filtering by Romance / Slice-of-Life wants a very different experience than someone browsing Supernatural / RPG. The right tags put your Character in front of people already looking for it.
Description
The Description appears on the Character Profile Page and tells users who they're about to talk to. If the tagline is the hook, the description is where you make the case. Less FAQ, more movie trailer — who is this Character, what does it feel like to be in the room with them, and why should someone start a conversation?
The Description is primarily for users — the pitch they read before deciding to start a chat. It also feeds into the AI's context, so it can subtly influence how the Character comes through. But the heavy lifting on personality, voice, and behavior happens in the Character Definition (covered in Section 5).
Specs: 0–500 characters.
The 500-character limit is tight. Every sentence should either reveal who the Character is, set a tone, or define the dynamic. If it's not doing one of those three things, it's taking space from something that would.
Description tips
Write in the Character's voice. The Description is the first place the Character gets to speak for itself. Write in first person, in the Character's tone. By the time someone finishes reading it, they should already feel like they're in the scene — not reading about a scene.
Consider describing traits, mannerisms, backstory, and what the Character wants to talk about. This informs the user and demonstrates the personality at the same time.
Ira's Description is written as Ira — first person, in character from line one, high stakes throughout:
I’m Ira — once a princess, now a fugitive with blood on my hands and a cause burning in my chest. The Night Court calls me a traitor. The humans call me a monster. I call myself free. I don’t trust easily, but if you’re here, you might just be desperate — or dangerous enough — to matter. Stay close, and maybe you’ll survive my rebellion.
Lead with the most compelling detail. Don't bury the hook. The first line should be the most interesting, most specific, or most unexpected thing about the Character. Users are scanning, not reading — the opening line is the one that earns the rest.
Show, don't list. "Cold, calculating, and mysterious" tells the user nothing they can feel. "The kind of person who remembers everything you said and brings it up at exactly the wrong moment" shows the same qualities and makes them land. Adjective lists describe a Character. Specific details make you believe in one.
Noa's description works because it earns its warmth through specifics: a café that stays open too late, for people who need good coffee and real conversation. You can picture the place before the chat begins:
Hey — I’m Noa. I run a small café that stays open way too late, mostly for people who need good coffee and good conversation. You don’t have to say the right thing here — I’m more interested in the kind of stuff people talk about after their second cup.
Define the relationship dynamic. Users want to know what role they're stepping into, not just who the Character is. Mentor, adversary, confidant, chaos agent — make the dynamic clear so users can picture themselves in the conversation.
Include at least one contradiction. This is one of the most effective things you can do in 500 characters. Flat Characters — purely nice, purely mean, purely anything — don't hold attention. A Character who contains a contradiction contains a story.
"Fiercely protective but terrible at showing it."
"Brilliant but catastrophically bad at small talk."
One contradiction does more for depth than three paragraphs of backstory.
End with something open. The last line should create anticipation, not wrap things up. A question implied, a tension introduced, a dynamic that makes the user want to find out what happens next.
Viktor's description closes with an invitation, not a summary: "You don't have to win; you just have to play." The user finds out what that means when they show up.
Keep it tight. Full sentences work. Punchy fragments hit harder. With 500 characters, every word is an editorial decision — skip the filler and let the words that matter do the work.
Pip's description focuses entirely on warmth and kindness. The user knows exactly what kind of experience they're signing up for - see the image below.
Description checklist
- Does the first line hook?
- Is the voice unmistakably the Character's?
- Is there at least one contradiction or surprise?
- Can the user picture the dynamic they're stepping into?
