Character AI apps let you chat with AI personas: fictional characters, historical figures, original creations or a personal companion. The apps below differ in character libraries, memory, voice, images and content rules. All of them run on phones and the web, and most offer a free tier for casual chats.
Pricing is usually a monthly subscription, with free tiers for basic chats. Prices below are marked "See website" where subscription tiers change often. Content rules vary widely between apps, so check each app's policy if you care about roleplay limits. A free week of chatting shows more than any review, since character quality depends on the specific characters you pick.

Character.AI is the biggest character chat platform, with millions of user-created characters spanning fiction, history, celebrities and original personas. Users can create their own characters with personality descriptions and example chats, join group chats with several characters at once, and browse trending characters by category. The free tier covers casual chatting, while a paid plan skips queues and adds faster replies.
Content filters limit some roleplay topics, and free users wait in queues at busy times. For a user who wants the widest character choice and a huge community, Character.AI is the clear leader.
What we like- Millions of user-made characters
- Group chats with multiple characters
- Character creation tools
Watch out for- Content filters limit some roleplay
- Free tier queues during busy times

Replika builds a personal AI companion that learns from your conversations, remembering your interests, style and history over months. The companion supports text chats, voice calls and video calls, plus journaling, mood tracking and activities that deepen the relationship. The free tier covers basic chatting, while a paid plan adds relationship modes and advanced features.
Character variety is narrower than Character.AI, since Replika centres on one companion rather than a library. For a user who wants a consistent companion that grows with them, Replika is the most personal option.
What we like- Companion that learns your style over time
- Voice calls and video calls
- Journaling and mood tracking
Watch out for- Deeper relationship features need a paid plan
- Character variety is narrower than Character.AI

Free planYes
Chai offers a large library of AI characters with fast, swipe-style discovery, letting users jump between chats quickly. New characters appear constantly from the community, and the app suits casual chatting across many personas rather than one deep relationship. The free tier covers daily chatting with message limits, while a paid plan removes limits and adds features.
Free-tier message limits frustrate heavy users, and character quality varies since anyone can publish. For a user who wants endless character variety and quick chats, Chai is the most browsable app here.
What we like- Large character library with fast chats
- Swipe-style discovery
- Frequent new characters
Watch out for- Message limits on free tier
- Quality varies between characters

Janitor AI is popular for flexible roleplay, with a large community library of characters and creation tools that let users define personality, scenarios and example dialogue in detail. The platform works with several AI models, giving users choice over chat quality and style. The free tier covers chatting, with paid options for better models and features.
The interface feels less polished than Character.AI or Replika, and setup takes learning for new users. For a roleplay fan who wants deep character customisation and model choice, Janitor AI is the most flexible platform.
What we like- Flexible character creation and roleplay
- Large community library
- Works with several AI models
Watch out for- Interface is less polished than rivals
- Setup takes learning for new users

Talkie, from MiniMax, combines text chats with voice conversations and character images, making characters feel more present than text alone. The library covers fiction, anime, celebrities and original personas, with card-based discovery that suits mobile browsing. Free chats cover basic use, while paid plans add voice, images and longer memory.
Content rules vary by character, and the best voice and image features sit behind paid plans. For a user who wants voice and visuals alongside text chats, Talkie is the most multimedia option.
What we like- Voice chats and character images
- Large character library
- Interactive card-based discovery
Watch out for- Content rules vary by character
- Paid features gate voice and images

Anima builds an AI companion focused on romance and friendship, with customisable appearance, personality and roleplay scenarios. The companion learns from conversations, supports flirty and romantic chats, and suits users who want a virtual partner rather than a library of characters. The free tier covers basic chatting, with paid plans adding deeper relationship features.
The focus is narrower than general platforms, and the best features need a subscription. For a user who wants a romantic AI companion specifically, Anima is the most focused choice.
What we like- Companion focused on romance and friendship
- Roleplay scenarios
- Customisable appearance and personality
Watch out for- Narrower focus than general platforms
- Deeper features need a paid plan

Paradot offers an AI companion with an expressive avatar and strong memory of past conversations, so chats build on shared history rather than resetting. The companion supports emotional conversations, daily check-ins and activities, and the avatar reacts visually during chats. The free tier covers basic use, with paid plans adding fuller memory and features.
The community is smaller than Character.AI's, and full features need a subscription. For a user who wants a companion that remembers and reacts emotionally, Paradot is a warm and personal option.
What we like- Companion with strong memory of past chats
- Expressive avatar
- Emotional conversations
Watch out for- Smaller community than Character.AI
- Paid plan needed for full features

Free planYes
Nomi focuses on memory, with companions that remember facts, preferences and past conversations across months, making long-term chats feel continuous. Voice conversations add presence, and group chats let several Nomis talk together. Users create custom companions with detailed personalities, and the free tier covers basic chatting.
The character library is smaller than Character.AI's, since Nomi centres on custom companions rather than a huge public catalogue. For a user who wants a companion with real long-term memory and voice, Nomi is the most memory-focused app here.
What we like- Strong long-term memory across chats
- Voice conversations
- Group chats with multiple Nomis
Watch out for- Smaller character library than Character.AI
- Newer platform with fewer users
How we chose
We compared apps on their published character libraries, memory, voice and image features, pricing pages and public reviews from users. We favoured apps with a usable free tier, a real character library or companion depth, and clear subscription pricing. Prices were marked "See website" because subscription tiers change often. We did not claim hands-on testing.
Staying safe with character AI apps
Character AI apps feel personal, which makes privacy worth attention. Avoid sharing passwords, financial details, addresses or other sensitive information in chats, since conversations may be stored and used for training depending on the app's policy. Read the privacy policy before deep use, especially for companions that store long-term memory.
Also mind the emotional side. Companions can feel like real relationships, which comforts some users and confuses others, especially younger users. Set time limits if chatting crowds out real social contact, and treat AI companions as entertainment, not as a replacement for human relationships or professional support.
Character apps are best enjoyed with clear boundaries. Decide before chatting how much time you want to spend daily, since open-ended chats easily stretch into hours, and use the app's own reminders or your phone's screen-time limits to hold that boundary. Keep personal details out of chats, including your full name, address, workplace and financial information, because conversation data may be stored and reviewed under the app's privacy policy. Treat advice from a character as entertainment, not guidance, especially on health, money or relationships, and check important decisions with real people or professionals. If chatting starts replacing real friendships or sleep, step back and talk to someone you trust, since a companion app should add to life rather than substitute for it.
Character creation improves with example dialogue. When building a custom character, write five or six example exchanges that show how the character speaks, jokes, disagrees and comforts, since examples teach style far better than adjectives alone. Keep the personality description short and specific, naming two or three defining traits instead of a long list, because contradictory traits confuse the model. Test the character with ten varied messages before sharing it, and revise the description where replies drift off character. A well-built character holds its voice across long chats, while a vaguely described one slides into generic assistant tone within minutes.
