Overview & Main Features
1. Character Creation
Character AI does what it says. It lets you create any character you want.
You can select the anime, voice, tone, personality traits, and even how they greet people. Then, the AI learns from your input. Over time, your character gets better at mimicking your intended behavior.
After signing up, the tool automatically assigned me a username, which I didn’t find pleasing (I changed it later on):

I found the interface to be as intuitive as it could be, this led me to explore the create option.

The tool asked for details concerning my intended character.

I filled in a name, tagline, and description.

I also added a greeting.

There was a voice feature included.

2. Privacy
Character AI lets you choose to keep your characters private or share them with the world. I decided to make mine unlisted, to allow for public access only via a link.

3. Voice Input and Output
On mobile, you can talk to the characters using your voice. I did start out with the text feature before I decided to engage the call feature. However, even in the text feature, I could listen to an audio transcription of my character’s response.

The call feature seemed normal, just like a regular call.

The character and I both had moments of speaking and listening. The AI did pick up on my words with accuracy except a moment when my voice wasn’t very audible. I also explored other characters created and made public by other users.

4. Group Chats
If you want a room where Sherlock Holmes, Elon Musk, and Tony Stark all debate quantum physics, Character AI can cater to that. The Group chat feature lets multiple characters interact in one space.
5. Memory
Characters may remember things you tell them and they try to stay consistent within a session. However, the full memory storage isn’t perfect yet.
6. Safe For Work
Character AI has a strict moderation filter to avoid harmful or NSFW content to keep things family-friendly.
