Nymbot - Private AI Chat

Nymbot is an AI assistant with no account attached to it. No email, no phone number, no password. Your identity is a key your own device generates, and you can throw it away and make a new one whenever you like.

Every message is end-to-end encrypted and gift-wrapped before it leaves your phone, so the relays carrying it cannot tell who is talking to whom, let alone what was said.

★ THE MODELS YOU ACTUALLY WANT

Claude, GPT, Gemini, Grok, Qwen, DeepSeek, Kimi and more, chosen per conversation. Every reply says which model wrote it and exactly what it cost, so switching models mid-chat is an ordinary thing to do.

★ TEN FREE REPLIES A DAY

No trial, no card, nothing to cancel. The daily allowance resets at midnight UTC and covers casual use on its own.

★ PAID IN SATS, NOT SUBSCRIPTIONS

Credits are bought with Bitcoin over the Lightning Network. Nothing recurring, no card on file, no minimum. A reply is metered on the tokens it actually uses, so a short question costs a fraction of a credit.

★ YOUR GIT REPOSITORIES

Connect a GitHub, GitLab, Gitea or Codeberg repository and ask about the code in it. Nymbot reads files, searches the tree and, when you turn writes on, commits changes and opens pull requests. Several repositories at once, ticked per conversation. Your access token stays on this device and is sent with each request; it is never stored on a server.

★ ANONYMOUS MODE

Move a conversation onto a throwaway key that is not linked to your main one, and let it carry credits across as blind vouchers we sign without being able to see them.

★ POST-QUANTUM BY DEFAULT

ML-KEM key encapsulation is combined with the classical exchange rather than replacing it, so an attacker has to break both. Traffic captured today does not become readable later.

★ BUILT FOR REAL WORK

Personas and custom instructions, a prompt library with fill-in blanks, file and image attachments, syntax-highlighted code with one-tap copy, replies read aloud, search across every message on the device, folders, tags, branching a conversation from any message, and full export.

★ GHOST CHATS

A ghost chat is never written to this device and publishes no archive copy. It is gone when you close the app.

★ ON EVERY DEVICE YOU SIGN IN ON

Settings, library and conversations are sealed to your own key, so the same account is the same app on your phone and on the web.

★ MORE THAN A HUNDRED LANGUAGES

The whole interface, not only the replies.

★ OPEN AND DECENTRALIZED

Built on Nostr, an open protocol nobody owns. There is no Nymbot account because there is no server holding one.

Nymbot is an AI assistant, so answering your question means reading it. We say that plainly rather than bury it: your messages are not used to train models and are not sold. Full detail at nymbot.ai/privacy.
