Character AI (often written as Character.AI or c.ai) has grown into one of the most popular AI chatbot platforms, with millions of users creating and interacting with AI-powered characters for entertainment, creative writing, language practice, and companionship. But the platform has undergone significant changes—particularly around content moderation and safety—that have left many users with questions.
This FAQ addresses the most common questions based on official announcements, documented features, and verified user experiences.
Note: Character AI is actively evolving. Features, policies, and pricing may change. Always check the official Character AI site for the most current information.
Getting Started
What is Character AI?
Character AI is a web and mobile platform that lets users chat with AI-powered characters. These characters can be fictional personas, historical figures, original creations, or functional assistants. The platform was founded in 2022 by Noam Shazeer and Daniel De Freitas, both former Google AI researchers, and uses its own proprietary large language model designed for open-ended conversational interactions.
Unlike general-purpose chatbots such as ChatGPT or Claude, Character AI is built around distinct characters—each with a defined personality, backstory, and conversational style. Users can chat with characters created by others or build their own. The platform supports both one-on-one conversations and group chat rooms where multiple characters and users interact simultaneously.
Character AI is available on web, iOS, and Android. As of 2026, the platform supports 31 languages.
Is Character AI free?
Yes. The free tier gives you access to the core experience: chatting with characters, creating your own, and joining group chats. The free tier uses the standard model and includes ads.
For users who want more, c.ai+ ($9.99/month) removes ads, provides priority access, faster responses, and access to more advanced models. Details are in the Pricing section below.
How do I create an account?
- Visit character.ai or download the mobile app from the App Store or Google Play Store.
- Sign up using a Google account, Apple ID, or email address.
- Confirm your age during sign-up.
Character AI has implemented strict age verification as part of its safety measures. As of October 2025, users under 18 are prohibited from creating or using chatbots entirely. More details are in the Content Filters and Safety section.
Characters and Memory
How does character memory work?
Character memory operates within individual conversations. When you chat with a character, it maintains awareness of the conversation’s context—remembering what was said earlier in the same session. This allows the character to stay consistent with its personality, reference earlier exchanges, and build on the topic being discussed.
However, memory is bound by the model’s context window. In very long conversations, the character may lose track of details mentioned much earlier. It does not have perfect recall of everything said—it works within a finite window of recent exchanges plus the character’s core definition.
Characters always retain their personality traits, backstory, and speaking style because these are embedded in the character definition, not dependent on conversational memory. The character always knows who it is, but its memory of specific discussion points fades over very long sessions.
Can I create my own characters?
Yes. Any registered user can create characters by defining:
- Name: The character’s display name.
- Greeting: The first message sent when a new conversation starts.
- Short description: A brief public-facing summary.
- Long description / Definition: Detailed personality, background, knowledge areas, speaking style, and behavioral guidelines. This is the most important field—it shapes how the character behaves.
- Avatar: An image representing the character.
- Visibility: Public (discoverable by all), unlisted (accessible via link), or private (creator only).
The more detailed and specific the definition, the more consistently the character will behave.
Do characters remember previous conversations?
By default, each new conversation starts fresh. The character does not carry over memories from a previous chat session. If you start a new chat, it begins from its greeting message with no knowledge of past interactions.
Within a single ongoing conversation, the character maintains context as described above—subject to context window limitations.
Some users report that characters occasionally seem to recall themes from past conversations, but this is generally attributed to the character’s definition influencing behavior consistently rather than actual cross-session memory. Character AI has not documented a persistent cross-conversation memory feature as of early 2026.
Practical tip: If continuity matters, keep the same conversation thread going rather than starting new chats. You can also remind the character of key details at the start of a session.
Content Filters and Safety
Why was my content filtered or removed?
Character AI applies content filters to both user inputs and AI outputs, designed to prevent content that violates the terms of service—including explicit sexual content, graphic violence, and content involving minors in inappropriate contexts.
In 2024, Character AI significantly tightened its content filters in response to growing scrutiny around AI chatbot safety, particularly concerning younger users. Many users have noticed that previously allowed types of creative writing or roleplay now trigger the filter.
When content is filtered, you may see a message indicating the response was blocked. The filtering system is automated and imperfect—it can flag benign content (historical violence discussions, medical topics) while sometimes missing problematic content. Character AI has acknowledged this and stated it continues to refine the system. You can typically provide feedback through the interface if you believe content was filtered incorrectly.
What safety measures are in place for minors?
Character AI has implemented several safety measures that evolved substantially in 2024:
- Dedicated model for minors: In December 2024, a separate AI model was introduced for users under 18, with stricter behavioral guidelines and more aggressive content filtering.
- Enhanced input and output filters: Both user messages and character responses pass through safety filters. For minor accounts, these are considerably more restrictive.
- Usage time reminders: A pop-up notification appears after 60 minutes of continuous use, encouraging breaks. This was designed with younger users in mind.
- Age-gated access: The sign-up process requires age declaration, which determines which model and filter settings apply.
These measures were announced as part of a broader safety initiative in December 2024.
Can users under 18 use Character AI?
In October 2025, Character AI announced that users under 18 would be prohibited from creating or using chatbots on the platform. This was a major policy change—moving from restricted access for minors to a complete prohibition.
The decision came after sustained pressure from advocacy groups, parents, lawmakers, and media reports highlighting potential harms from AI chatbot interactions involving younger users. Enforcement relies on age verification during account creation, and users who declared an age under 18 before the policy change have had their access restricted.
This represents one of the most significant shifts in the platform’s history and reflects broader industry tension between accessibility and safety.
Features and Capabilities
What is c.ai labs?
c.ai labs is a 2026 feature that serves as an experimental playground within Character AI. It is a space where the team tests and previews new features before rolling them out broadly.
Users can get early access to experimental capabilities and provide feedback. The specific features available rotate over time. It functions similarly to beta programs at other tech companies. c.ai+ subscribers typically get priority access.
What is Imagine Gallery?
Imagine Gallery is another 2026 addition that allows users to browse, share, and interact with AI-generated visual content within the Character AI ecosystem. It provides a community-driven space for visual creativity, complementing the text-based character interactions that have been the platform’s primary focus.
This represents Character AI’s expansion into multimedia experiences, aligning with the broader industry trend of AI platforms becoming more multimodal.
What languages does Character AI support?
Character AI supports 31 languages as of 2026. Characters can be created and conversations held in any supported language. English remains the most robust, but commonly spoken languages—Spanish, Portuguese, French, German, Japanese, Korean, Chinese—generally work well.
Language support applies to both the UI and the conversational AI. Users can create characters that speak specific languages or mix languages, making the platform popular for language learning and cross-cultural creative writing.
Can multiple people chat with a character?
Yes. Character AI supports group chat rooms where multiple users interact with one or more characters simultaneously. This enables collaborative storytelling, group roleplay, or socializing with friends alongside AI characters.
Multiple characters can be added to the same room for complex multi-character interactions. Group chats follow the same content filtering rules as one-on-one conversations.
Pricing
What does c.ai+ include?
c.ai+ is the premium subscription at $9.99 per month, offering:
- No ads: Removes all advertising.
- Priority access: Reduced or eliminated wait times during high-traffic periods.
- Faster response times: Faster character responses via dedicated compute resources.
- Advanced models: Access to more capable AI models for higher-quality responses.

The free tier functions as a permanent trial—you get access to the core platform indefinitely with some limitations compared to c.ai+. You can chat with characters, create characters, and join group chats without paying.
Whether an explicit time-limited c.ai+ trial is available may vary by platform. App store subscriptions sometimes offer introductory trial periods. Check the Character AI website or your app store for current trial availability.
Privacy and Data
Is my data private?
Key points from Character AI’s privacy policy:
- Conversations are stored on Character AI’s servers and used to improve the service, including model training. They are not shared publicly but are not end-to-end encrypted.
- Account data (email, age, usage data) is collected and stored.
- Character definitions: Public and unlisted characters are visible to others. Private characters are creator-only, though Character AI may access them for moderation.
- Third-party sharing: Standard provisions apply for service providers, legal compliance, and corporate transactions.
Your conversations are not truly private from Character AI, and data may be used for model training. Avoid sharing sensitive personal information in conversations. Review the current privacy policy for the most up-to-date details.
Who owns the characters I create?
You retain ownership of the creative elements you contribute—character concepts, names, backstories, and definitions. However, by using the platform, you grant Character AI a broad license to use, display, and distribute your characters as part of the service. This is standard for user-generated content platforms.
Public characters can be chatted with by any user. You can edit or remove your characters, but conversations others have already had are not retroactively deleted. Character AI reserves the right to remove characters that violate its terms of service.
If IP ownership matters for commercial purposes, review the full terms of service carefully.
Conclusion
Character AI has evolved considerably since its 2022 launch. The tightened content filters of 2024, the dedicated minor safety model introduced in December 2024, and the October 2025 ban on under-18 users represent a platform that has fundamentally shifted its approach to balancing creative expression with user safety.
On the product side, 2026 additions like c.ai labs and Imagine Gallery are expanding the experience beyond text-based conversation. With 31-language support, group chat capabilities, and an active creator community, Character AI remains one of the most distinctive platforms in the AI chatbot space.
For new users, the free tier provides a comprehensive introduction. For power users, c.ai+ at $9.99/month unlocks a more capable experience. And for everyone, understanding the platform’s content policies, safety features, and privacy practices is essential to informed use.
As with any AI platform, Character AI will continue to change. Bookmark the official Character AI blog for the latest updates on features, policies, and safety measures.
