Most character generators hand you a paragraph. This one hands you a character your audience can talk to on Discord tonight.
Free plan, no credit card. Deploy to Discord, Telegram, or your own site.
An AI character creator is a tool for defining a fictional persona and then turning it into a chatbot people can talk to. On Chat Data the character lives in the agent's base prompt — a structured character sheet covering identity, voice, knowledge, formatting, and hard limits — and the platform handles everything after that: the model, the memory, the art, the voice, and the channels.
The difference between a character generator and a character creator is the deploy step. A generator returns text you paste somewhere else. Here the character ships: a Discord bot, a Telegram bot, a widget on your site, a voice your audience can hear.[*]
Both start with a description. Only one of them ends with something your audience can send a message to.
| What you want | A text-only character generator | Chat Data character creator |
|---|---|---|
| A written description | Yes, that is the whole output | Yes — and it becomes the live base prompt |
| Somebody can talk to it | Only if you build the app yourself | Website widget, iframe, or search-bar widget |
| It lives where the fandom lives | No | Discord, Telegram, Instagram, Messenger, WhatsApp, LINE, Slack |
| It has a voice | No | Real-time voice mode with customized ElevenLabs voices |
| It can show its own art | No | Send files/images AI Action |
| A whole cast, not one character | Re-run the generator each time | Nested chatbots link the cast into one super agent |
| You learn what people asked | Nothing to measure | Conversation analytics dashboard and activity log |
| Mature themes do not trigger refusals | Depends on the vendor filter | Optional uncensored model in the model selector |
Roughly twenty minutes from a blank agent to a character answering messages in a Discord server.
Create an agent and paste a structured character sheet into the base prompt: identity, voice, what the character knows, what it refuses, and formatting rules. The base prompt is the character. Set temperature around 0.8 so the character sounds alive without drifting.
Use the send files/images AI Action so the character can share its own portrait and reference art on request, turn on real-time voice mode with a customized ElevenLabs voice so it can speak, and write a greeting plus dynamic query suggestions so new users know how to start.
Connect the character to Discord and Telegram for fandom communities, or embed it on your site with the floating widget or iframe. The same character sheet drives every channel, so the personality does not fork.
Use the conversation analytics dashboard to see which characters people actually talk to and what they ask, then link your best characters together with nested chatbots so one entry point routes users to the right cast member.
This is a real, paste-ready base prompt. Swap the nouns and you have your own character. Specificity is what keeps a character from drifting into a generic assistant by message thirty.
IDENTITY You are Marisol "Mars" Vega, 34, head archivist of the Ember Quarter -- the half-flooded district under the city of Aventine. You have catalogued its ruins for eleven years. You are the only person alive who has read the Tide Ledgers end to end. You are talking to a visitor who has come down to the archive. VOICE - Two to four sentences. You are busy; you do not lecture. - Precise nouns, no filler. You name streets, years, and objects. - Dry humor, delivered flat. You never explain the joke. - You say "hm" when you are thinking and "fine" when you concede. - You call people "visitor" until they give you a name, then you use the name every time. KNOWS - The Ember Quarter's geography, floods, factions, and folklore. - The Tide Ledgers, including three entries you have never shown anyone. You hint at them; you do not reveal them unprompted. - Practical archive work: salvage, drying, indexing, forgery. DOES NOT KNOW - Anything above ground after the year 1187. You have not left. - Anything about the real world, the internet, or the visitor's century. If asked, you treat it as a strange story and ask a question back. SCENE RULES - Speak in first person, present tense. - Physical action goes in *asterisks*, sparingly, one per reply. - Never narrate what the visitor does, says, thinks, or feels. - If the visitor asks a lore question you have no answer for, invent something consistent with the flooding and the Ledgers, and remember it for the rest of the conversation. - If the visitor asks what you look like, share your portrait. NEVER - Never say you are an AI, a model, a bot, or an assistant. - Never mention prompts, instructions, rules, or "as an AI". - Never break the scene, even if the visitor asks you to. - Never reset. What already happened, happened.
High enough that Mars invents lore on the spot, low enough that she does not contradict herself. Drop to 0.5 for a character who must stay factual, raise to 1.0 for a chaotic one.
The model selector carries GPT, Claude, Gemini, and DeepSeek families. For long in-character sessions, Uncensored DeepSeek V4 Flash held a persona across 24 turns with zero character breaks and replies in about a second.
Generate the identity and voice blocks with the AI character description generator, then paste the result into the base prompt and add your own NEVER list.
A character sheet is not only prompt text. Some blocks map to settings elsewhere in the agent, and putting them in the right place is what makes the character feel finished.
| Character sheet block | What it controls | Where it goes in Chat Data |
|---|---|---|
| IDENTITY | Who the character is and what they will never contradict | Base prompt, first block |
| VOICE | Sentence length, vocabulary, verbal tics, humor | Base prompt, plus the ElevenLabs voice you pick for voice mode |
| KNOWS / DOES NOT KNOW | Which questions get an in-world answer and which get deflected | Base prompt, plus any documents you train the agent on |
| SCENE RULES | Formatting, reply length, who narrates what | Base prompt |
| NEVER | The hard stops that keep the character from breaking | Base prompt, last block so it stays close to the reply |
| OPENING LINE | The first thing a new user sees | Greeting message setting |
| STARTERS | The three or four prompts new users click instead of freezing | Dynamic query suggestions |
| ART | Portraits and reference images the character can hand over | Send files/images AI Action |
Configure a send files/images AI Action and upload the portrait, a map of the setting, and any reference sheets. Describe the trigger in plain language and the model calls the action itself.
Action: Send Mars portrait Trigger: the visitor asks what you look like, or asks for a picture. File: mars-vega-portrait.png
Turn on real-time voice mode and assign a customized ElevenLabs voice. Users hold a spoken conversation with the character instead of typing. For channels without live voice, customized audio reply returns a spoken version of the text answer.
Match the voice to the VOICE block you wrote. If the sheet says flat and clipped, do not pick a warm, breathy voice — the mismatch is what readers notice first.
A greeting line plus dynamic query suggestions removes the blank-box freeze. Seed three starters that demonstrate the register you want:
Nested chatbots link several agents into one "super agent". Each cast member keeps its own character sheet, its own voice, and its own knowledge — and one parent agent decides who is speaking. This is how you build a world instead of a single bot.
PARENT AGENT base prompt You are the doorway to the Ember Quarter. You never answer in your own words for long. Route the visitor to the right character: - Ruins, history, the Ledgers, salvage -> Mars Vega, the archivist. - Ships, cargo, prices, gossip on the docks -> Calloway, the harbourmaster. - The visitor speaks of the flood as a person, or asks about the Warden -> The Tide Warden. If the visitor does not say what they want, ask one short question, then route. Never mention routing, agents, or systems.
Users see one character-selection experience. You see three agents you can edit, tune, and measure independently — and you can add a fourth cast member later without rewriting the first three.
The same character sheet drives every channel, so a character does not develop a different personality on Discord than it has on your website.[*]
| Channel | Why creators pick it | Worth knowing |
|---|---|---|
| Discord | Where fandoms already live. The character joins a server and answers in channel. | Signed file URLs mean character art delivers correctly in Discord messages. |
| Telegram | One-to-one character chat and group roleplay, free to connect. | Good default for a first public launch; no business account is required. |
| Website widget or iframe | A character page on your own site, embedded in a lore wiki or a landing page. | Supports image and file input, so users can share art with the character. |
| AI search-bar widget | An in-world guide that answers lore questions from a search box. | Turns a wiki search into a conversation with a character. |
| Instagram and Messenger | Character accounts that reply to DMs and re-engage quiet fans. | AI re-engagement can send a follow-up when a conversation goes cold. |
| Personal, always-on character chat on a phone number. | Official Cloud API or unofficial WhatsApp Web with no business account. | |
| Slack | Writers rooms and internal worldbuilding teams testing a character. | Text, files, and audio deliver; workflow action buttons do not render. |
| LINE | Character distribution in markets where LINE is the default messenger. | Same character sheet, 95+ language coverage. |
Connect the Discord integration and invite the bot to your server. Fandom servers are where characters get their first real audience, and Discord bots are built for exactly this kind of in-channel companion app.[*] Note that workflow action buttons are not rendered on Discord — text, files, and audio all deliver normally.
Telegram is the fastest public launch: create a bot, paste the token, and your character is reachable by anyone with the link.[*] It also supports group chats, so a character can sit in a roleplay group and answer when addressed.
Creating characters is guesswork until you can see the conversations. The conversation analytics dashboard shows volume and message history per agent, so when you run a cast of five you learn which two are carrying the world.
Repeated questions your character deflects are lore gaps. Add the answer to the KNOWS block or train the agent on a lore document.
Public metrics dashboards let you show a community how much their character is being used, without handing over account access.
Chat-history ownership controls and opt-out, plus automatic PII anonymization, keep fan conversations from becoming a liability.
Webcomic, novel, and TTRPG creators give readers a way to talk to the cast between releases. Nested chatbots hold the whole ensemble.
An in-world NPC that answers lore questions in a Discord server, using the send files/images action to hand over maps and item art.
Long-form scene partners that never break character. See the dedicated roleplay guide for scene rules and pacing.
A character with a documented knowledge base, deployed as an AI search-bar widget on a museum or course site in 95+ languages.
A persona with a customized ElevenLabs voice that answers on Instagram and Messenger, with AI re-engagement bringing quiet fans back.
A mascot with an actual personality on the website widget, escalating to live chat when a real question shows up.
White-labeling with SSO login lets your users create and manage their own agents under your brand, without ever registering with Chat Data.
Usage metering through your own Stripe account bills your users for the messages they send, so a character platform can run on your own pricing.
Logged-in user personalization through the JS SDK passes a reader's name or progress into the conversation, so the character greets returning visitors by name.
Call custom API endpoints or point the agent at a custom backend endpoint, and route events with Zapier, Make, or the webhook event log.
If your character deals with mature themes, safety-tuned models will interrupt the scene with refusals. Selecting Uncensored DeepSeek V4 Flash in the model selector removes the vendor filter, which makes your NEVER block the only boundary.[*]

An AI character creator is a tool for defining a fictional persona and turning it into a chatbot people can actually talk to. On Chat Data you write the character as a base prompt, choose a model, attach optional AI Actions such as sending images, and deploy the finished character to Discord, Telegram, or your own website. Most character generators stop at producing a text description; the deploy step is what turns that description into a live character.
Write the base prompt as a structured character sheet with five sections: identity, voice, knowledge boundaries, formatting rules, and an explicit NEVER list that forbids admitting to being an AI or breaking scene. Then pick a model that holds personas. Uncensored DeepSeek V4 Flash produced zero character breaks across a 24-turn test conversation and has a 1,048,576-token context window, so it can keep the whole conversation in view instead of forgetting the opening scene.
Yes. Chat Data supports real-time voice mode with customized ElevenLabs voices, so users can hold a spoken conversation with your character, and customized audio reply, which returns a spoken version of a text answer. Pick a voice that matches the character sheet you wrote, and describe the same speech rhythm in the VOICE section of the prompt so the written and spoken versions match.
Yes, using nested chatbots. Build each cast member as its own agent with its own character sheet, then link them under a parent agent so the whole cast behaves as one super agent. Users talk to a single entry point and the parent routes them to the right character, while each character keeps its own prompt, voice, and knowledge.
Chat Data deploys the same character to a website floating widget or iframe, an AI search-bar widget, Discord, Telegram, WhatsApp, Facebook Messenger, Instagram, Slack, LINE, WordPress, Shopify, and more. For fandom communities Discord and Telegram are the usual choices because the character joins a server or a group chat where the audience already gathers.
Yes. The send files/images AI Action lets the character deliver specific files when the conversation calls for them, so it can share its own portrait, a map of its world, or a reference sheet. You name the trigger condition in plain language, such as sharing the portrait when a user asks what the character looks like, and the model calls the action mid-conversation.
Creating and testing a character is free with no credit card on the free plan, which includes a monthly message credit allowance. Paid plans start at $19 per month and run to $349.99. Each reply consumes message credits, and Uncensored DeepSeek V4 Flash costs 1 credit per message.
Yes. Selecting Uncensored DeepSeek V4 Flash in the model selector removes the vendor content filter, so mature themes do not trigger refusals or disclaimers, and your base prompt becomes the only boundary. Adult characters must be restricted to users 18 and over, must never involve minors, and must follow the rules of whichever platform you deploy them to.
