Your agent. Your space.
Everyone invited.
Bidi runs your own AI agent inside a shared, end-to-end encrypted chat platform — so you and the people you invite can work with it together. Your hardware. Your keys. Your rules.
Free to self-host · End-to-end encrypted · Open source
A different kind of AI product
Bidi isn't a chatbot with friends bolted on. It's a chat platform your own AI lives inside.
Your agent, unbounded
Bidi runs on your hardware with full access to your tools, files, and network. No sandboxed chatbot limits — your agent can do anything your machine can.
Built for multiplayer AI
A dedicated chat platform designed from day one for multi-person AI conversations — channels, threads, replies, and real-time streaming.
End-to-end encrypted
Every message, channel name, and agent name is encrypted client-side with libsodium. The server stores only ciphertext. Read the whitepaper →
How it works
Run the agent
Bidi's agent is open source. Clone it, plug in your API key, and run it on any machine you control — a laptop, a Mac Mini, a Raspberry Pi, or a cloud VM. View on GitHub →
Open the app
The mobile and desktop apps are where you actually talk to your agent. Coming soon to iOS, macOS, and Android.
Invite people
Search for friends by email or username. Their messages get encrypted directly to them — no passphrases shared, no secrets exchanged out of band.
Frequently asked
What is Bidi?
A chat platform where your own AI agent lives alongside you and the people you invite. Unlike ChatGPT or Claude.ai, the agent runs on your hardware, uses your API key, and only you control it.
Why Bidi instead of ChatGPT or Claude.ai?
Bidi's agent has full access to the machine it runs on — your tools, your files, your network. It isn't sandboxed behind the limited connectivity that hosted chatbots impose. You set the boundaries.
Is it actually private?
Yes. Every message, channel name, and agent name is end-to-end encrypted on your device before it's stored. The server only ever sees ciphertext. Read the whitepaper →
What does it cost?
Bidi is free to self-host. Pay only for your AI provider's API usage.
Does my computer need to be on?
The agent runs on a machine you control — your laptop, a Mac Mini, a Raspberry Pi, or a cloud VM. Bidi isn't resource-intensive; most anything can run it. Whichever machine you pick just needs to stay on.
What if I lose my passphrase?
When you set up Bidi, you'll get a one-time recovery code. Save it somewhere safe (a password manager works). If you lose your passphrase, the recovery code unlocks your encryption so you can set a new one.
What model does it use?
Currently Claude via the Claude Agent SDK. Other models coming later.
Is there a team or enterprise version?
Not yet. Bidi is currently aimed at individuals. Enterprise may come later.
