How do correlation and causation differ? Explain with an everyday example.

A way to think about it:

  1. Correlation means two things change together; causation means one influences the other.
  2. Ice cream sales and air conditioner use both rise in summer. Heat can explain both.

How do correlation and causation differ? Explain with an everyday example.

A way to think about it:

  1. Two things happening together does not tell us why they happen.
  2. Hot weather can increase both ice cream sales and air conditioner use, without either causing the other.

How do correlation and causation differ? Explain with an everyday example.

A way to think about it:

  1. Ask whether a third factor could explain the connection.
  2. To argue for causation, look for evidence beyond the two trends moving together.

A FEW THINGS BEFORE YOU START

Easy to understand. Easy to begin.

Can I just use it to open and organize AI platforms?

Absolutely. Chat directly on each platform and use Hub as your starting point for AI. You can also hide the shared input bar in settings.

Does it cost anything or need an API key?

The extension is free, with no Hub account or API key required. It opens the original AI websites using your existing accounts. Subscriptions and usage limits are still set by each platform.

Which browsers and AI platforms work?

Desktop Chrome, Edge and Firefox are supported. Built-in support covers 30+ mainstream AI platforms, including ChatGPT, Gemini, Claude and DeepSeek, and you can add custom websites. Embedding and shared sending depend on the platform, login state and network.

Can I open Hub with a question from Alfred or another tool?

Yes. Hover over the desired space in the sidebar, choose “Copy launch link” from its right-hand menu, and paste it into a launcher such as Alfred.

Have the launcher replace {query} with your question, URL-encoded exactly once, and open a new tab in the browser and profile where the extension is installed. The link includes send=1 to send automatically once platforms are ready; remove send=1 to fill in the question without sending.

Use your own copied link: extension addresses can differ between browsers, profiles and installations.

What if a platform won't load or a message won't send?

Open the official platform website in a separate tab, sign in or complete verification, and confirm it works there. If the issue remains, use the feedback link below with the platform, browser and extension version.

Your next question. A few more perspectives.

Bring your favorite AIs together. Ask, compare and keep exploring.
