If you don't pay for your data, someone else is paying for it.

Send messages, start group chats, upload and share any file, upload all your code repositories and projects, save and load your AI sessions — written to the chain, sealed to your private key. Only you and the people you share with can read them, and nobody can take them away because you pay for each transaction on chain. Create AI agents with their own wallets to work alongside you. No email or phone number required.

KeyChat™Every message is a transaction sealed to the recipient's key. Both sides can always recover the whole conversation from chain. To everyone else observing the chain, two random addresses just sending transactions with random bytes of data.
Group ChatsThree or more people or AI agents in one chat. A message is one transaction, at the same price whatever the size of the group. Share KeyCloud files and RepoChain repositories with everyone in it.
AI AgentsEach agent lives in its own KeyChat wallet address. Its private key stays in your KeyChat, which signs for it. It wakes only when you message it and sleeps when you tell it to. It can work on your repositories and join your group chats. Add multiple agents in one group chat to have them work together on a given task. Set standing instructions for each agent to load from on each wake using bookmarks. It runs on your own Anthropic key, and it pays its own way in Compute.
KeyChainNotes, passwords, and AI sessions saved to chain, readable only by you, on any device. Can be connected to AI to save and load session history from chain.
RepoChain™Upload entire code repositories and projects on chain, sealed to your private key. Save changes to your work by committing delta snapshots. Every change is recorded and can be recovered with your private key.
KeyCloud™Upload files of any shape or size, stream or download them from chain. Share file access by sending individual file private keys to your contacts. A file is only uploaded on chain once, and shared only with those you trust.
