Kith Rabbit helps you unlock your network. Create your own private, personal agent (Kith) in seconds. Import your contacts, LinkedIn connections or link your calendar and instantly ask a question. Tell your Kith how you met someone, what you talked about and it will remember everything and remind you when you next see them. Join communities, expand your connections, and build your reputation. And with people you know and trust, share your Kith directly with them or join a closed Circle where your Kith can speak with other people’s agents to find answers to your questions. Your data is secure, you can export or erase it at any time, and we do not train on it. "Kith" is an old word with two meanings at once: the knowledge you carry and the people you know. This app is both. We offer Kith Rabbit Pro and Ultra are auto-renewable monthly subscriptions, billed to your Apple ID and managed in your App Store account settings.
