One provider plan. Everyone you invite.

Zyrdon is free and open source. Run it all yourself, or let us run parts of it for you.

Zyrdon is a private AI chat server. It puts the Grok, ChatGPT, or API key access you already pay for on a server you control. People you invite chat in a native app, each in a private run. They share the bill, not the chat.

No per-person plan. The server is the only customer the provider sees.

Share the subscription: Not the conversation. History stays with that person.
Private run: Each run has its own working folder. Files and chats do not leak across people.
You pick who gets in: Invite with a device code. Cut access later if you want.

Bots with a purpose

A bot is a chat with one purpose that lasts. It remembers what you told it, works in the background, and comes back when it has something for you. Each person's bots are their own.

Start one in a sentence
Say what the bot is for. It picks its own name, keeps that purpose in memory, and needs no setup.
Write any time
Send as many messages as you like, even while it works. Long tasks run in the background and report back, so a quick question still gets a quick answer.
Routines it sets itself
Ask for a reminder or a daily check, and the bot sets up the routine. Every routine shows in the bot's details, where you can pause or delete it.
It follows up
Leave a topic unfinished, and the bot can come back later with what it found or one short question. You set how proactive each bot is, from None to High.

Acts turn rough words into ready text

An Act is an instruction you save once and reuse. Say or type the rough version, and it gives back text ready to paste into a coding agent, a chat app, or wherever it needs to go.

Save it once
Write how the result should read and pick the assistant that runs it. Your Acts follow you to iPhone and Mac. Start from Better Prompt or write your own.
Speak from any app on Mac
Press a shortcut without leaving the app you're in, then talk or type. The result is copied, or pasted straight into that app if you turn that on, and never into another one.
Run one in any chat
Type / and the Act's name in a chat on iPhone or Mac. Then insert the result into your message, or copy it.

How you run it

Run it all yourself

The server runs on macOS and Linux, from source or in Docker. You keep the provider sign-ins, the conversations, and the keys. Push works with an app you sign yourself, and remote access with your own tunnel.
