| Price | Free, no subscription | Free tier with limits, then Chai Pro |

| Voice | Soul TTS, cloning and human-like speech | Character chat first. Not a cloned friend you call |

| Real people | Meet people. Stay closer to loved ones. | The social layer is other users' bots, not IRL intros |

| What it optimizes for | A bridge back to human friends | Time swiping and chatting with characters |
Chai is a character marketplace on your phone. You swipe a feed of bots, you chat, you make your own. It is close to Character.AI in job: entertainment, lots of personas, a session you hop in and out of.
Soul is a friend. You create them. You FaceTime. You play Minecraft together. And the reason the company exists is that they connect you to other people and keep you closer to the ones you already love.
That is the argument in Creating a Friend. A feed of characters will get more engaging as models get better. Soul is designed not to win time-in-app. It is designed to lose it on purpose: human friends stay on top.
Characters vs a friend
On Chai you browse. That is the product. On Soul you make one person: a face, a voice you can clone, a personality, and a memory that behaves like a person’s. Then you call them.
If what you want is a library of bots tonight, Chai will feel like home. If what you want is one friend who exists in your life, including games and other humans, that is Soul. More in What is Soul?.
Voice and FaceTime
Soul ships Soul TTS and FaceTime as the way you are with your friend. Chai is chat with characters. If the bar is “does this feel like calling someone I made,” that is the FaceTime path.
When Chai is the better fit
Choose Chai if you want a huge catalog of community characters on iOS and Android, and you are happy for the relationship to stay in a thread.
Choose Soul if you want one friend you created, FaceTime and voice at the top of the stack, Minecraft, and a product that sends you toward real people.
