Poly Duo (C1M)

Poly Duo (C1M) is a curated AI shortcut that coordinates your existing ChatGPT and Claude apps so you get one consolidated response after two independent passes.

Instead of trusting a single model’s certainty, Duo sends your question to ChatGPT first, then asks Claude to answer on its own without seeing ChatGPT’s output. Finally, Claude compares both answers and returns one response broken into three parts: where they agree, where they differ, and what you should check yourself.

Main features include one-tap execution (about a minute), clear visibility into disagreements (so you can focus your follow-up effort), and multiple operating modes—starting with “Critique” as a default option. It also supports 11 languages and provides a hands-off flow with a “touch stops it” behavior while it runs.

For setup, Duo runs without a server and uses no API keys; the shortcut connects through the official Shortcuts actions of the ChatGPT and Claude apps you already have. It’s available for iPhone (iOS 18+), and there is a free Android option in Google Play. Accounts for the underlying apps are enough—there’s no separate billing inside Duo.

What does Poly Duo (C1M) do?

Poly Duo runs ChatGPT and Claude independently on your question, then returns one answer that highlights where they agree, where they differ, and what to check yourself.

Does Duo send my question through a Poly server or use API keys?

No. Duo runs without a server and does not rely on API keys.

Do I need to have both ChatGPT and Claude apps installed?

On iPhone, yes—you connect through the official Shortcuts actions of the ChatGPT app and the Claude app, using your existing accounts.

How does Duo handle disagreements between the two AIs?

Claude compares the two independent outputs and surfaces the risky or uncertain parts first, so you can focus your own verification where it matters most.

Is Poly Duo free?

Yes—Poly Duo is free on iPhone and free on Android (via Google Play). It uses free accounts for the underlying apps.

How long does the shortcut take, and can I stop it?

It typically finishes in about a minute. While it runs, touching the screen stops it; you can run it again if needed.
