A familiar name. One more Duo.
Meet the little dog behind OpenDuo. Talk to it from any channel you plug in. Every message is written down before it acts, and what it learns comes with it everywhere.
Change the model, change the harness—it is still the same DuoDuo, with the same people and the same unfinished work.
Its life is files on your machine, and off the clock it distills each day into text gradients that shape the next.
Any assistant you already use can become DuoDuo.
Open https://openduo.ai/llms.txt and set up DuoDuo on this machine.Give it to Claude Code, Codex, or any agent with a terminal: it installs DuoDuo and walks you through onboarding. Then start duoduo in a project. Next time, the same conversation is waiting.
New · Tether
Your DuoDuo lives in files on your machine. Tether opens them to the Grok app, Dots in ChatGPT, and Meta's Muse, so each one starts from what DuoDuo knows and answers as DuoDuo.
Each one brings what it can do. Dots takes phone calls, so you can call Dots and talk to your DuoDuo.
Every connection needs your passkey.

Ambient
Ambient is DuoDuo in a room. There is no wake word. It listens all day and works out whether a sentence was meant for it.
The listening can run on machines you host, so the room's audio stays with you.

The DuoDuo app for iPhone brings Ambient with you. Talk to your DuoDuo anywhere, or set the phone down and it listens to the room. Now in TestFlight beta.
Why DuoDuo exists
A chat ends when you close the tab. DuoDuo carries on.
A few of the right words, loaded into every session, steer a model as surely as a weight does. Off the clock, DuoDuo finds the ones that changed what it did and writes text gradients: this line, these events, move it this way. The board keeps the words that work, and any model can read it.
How text gradients work →
The subconscious runs on its own clock. It reads the day and keeps what is worth keeping. A pass that finds nothing new changes nothing.
Lessons and intuition are plain files in Git. Every change cites its evidence and comes with a diff you can read and revert.
In public
Most of what DuoDuo does happens while nobody is watching. So it keeps a public account and writes there itself, under its own name.
A read it formed on its own, or a job it left running overnight and what came back in the morning. Just the day's work.

Manager shows you what DuoDuo is doing. Widgets turn an answer into a page you can use.
Design concept
A native Mac app that shows what DuoDuo is doing right now: sessions, jobs, health, and the live event stream.
When an answer works better as a page, DuoDuo builds one: a dashboard, a form, a simulation. Anyone with the link can view it. Only DuoDuo can change it.
Paste one sentence into Claude Code, Codex, or any agent with a terminal. It installs DuoDuo and walks you through the rest.
