Build with AI together: pair prompting on one screen

Watch the 40-second demo: Pair prompting: how two people build with AI on one screen.

Short answer: most AI building tools, from Cursor and Claude to Lovable and ChatGPT, are designed for one person at the keyboard. To build together, share the screen of the person whose project it is and let the other person type too. With Pairio, both of you use your own mouse and keyboard on the same screen: one writes the prompt, the other reads the output and fixes the code.

Why this matters now

More and more software is built by talking to an AI. That work is still mostly done alone, while the best prompts often come from a second person: someone who knows the product, spots the mistake in the output, or asks "why don't you ask it to...". Pair programming taught us that two people catch more than one. Pair prompting is the same idea for the AI era.

Typical moments:

• A founder and a developer shaping a prototype together in an AI app builder.
• A product manager reviewing what an agent built and steering the next prompt.
• A mentor helping a student who is stuck halfway through a project with an AI assistant.
• Two friends building a side project on a Sunday afternoon.

How to do it with Pairio

1. The person with the project installs Pairio on their Mac. The other person can do the same, or simply join from their browser with a link, on any computer.
2. The person with the project calls the other with one click, and shares their screen.
3. Split the roles. One drives the AI (writes prompts), the other navigates: reads the output, checks the code, thinks ahead. Swap every 20 or 30 minutes.
4. Let the navigator type. When the navigator has a better prompt, they write it themselves with their own keyboard, straight into the chat box or the editor. No dictating.
5. Point at the problem. Circle the line in the diff or the error in the terminal with the pen.
6. Pass snippets around. The shared clipboard means text you copy on one Mac can be pasted on the other. Files can be sent during the call.

Why a normal video call falls short

• Code and AI output need to be readable. Meeting tools compress the shared screen, so small fonts in an editor or terminal turn blurry. Pairio keeps text sharp.
• Two people need to type. In most meeting tools, only the person sharing can type, and the other has to dictate.
• The moment is short. "Can you look at this prompt?" should not need a meeting link. In Pairio you click a name.

Good habits for pair prompting

• Agree on what you are building before you start prompting. Write it as one sentence at the top of the chat.
• Read the AI's plan together before you let it change files.
• Review the diff together, not just the result in the browser.
• Keep a short log of prompts that worked. They are reusable.
• Hide what does not belong in the call. Pairio can hide apps such as Messages or Slack from the person watching.

When Pairio is not the right choice

• The project lives on a Windows or Linux computer and the other person needs to take over. Someone joining from the browser can work on a shared Mac screen, but on a screen shared from the browser, others can only draw.
• You want to build together asynchronously. Then a shared repository or a tool with built-in collaboration fits better.
• You are with more than 4 people. Pairio supports up to 4 people per call.

Questions people ask

Does this work with any AI tool? Yes. Pairio shares your whole screen, so it works with any app or website: Cursor, VS Code, Claude, ChatGPT, Lovable, a terminal, anything.

Does the other person need an account for the AI tool? No. They work in your session, on your screen, while you are there.

Does the other person need a Mac? No. They can join from their browser and still type and click on your shared Mac screen.

Is it free? Each person gets 10 hours per month for free, with every feature. Pro is $15 per month for unlimited hours.
