About image upload: Even with auto-send off, the image may be uploaded to ChatGPT or Gemini when it is attached during preparation. Reviewing before sending lets you check what goes into the conversation; it does not mean the image stays inside the extension. See the privacy policy for details.

Capture with AreaShot, then use PicPreset

On Windows, AreaShot is a convenient way to capture just the area you need, copy it to the clipboard and pass it straight to PicPreset without saving an image file first.

  1. Press AreaShot’s shortcut (default: Ctrl+Alt+S), select an area and choose Copy to clipboard. Add arrows or text first if needed.
  2. In Chrome, open an empty ChatGPT or Gemini chat and press PicPreset’s shortcut (default: Ctrl+Shift+Y).
  3. Check the preset and image, click Prepare, then review and send.

AreaShot is optional. You can also use an image captured with Win+Shift+S or any other copied image.

When it helps

If your image changes but your instructions stay the same, save those instructions as a preset and reuse them.

  • Screenshots into illustrations

    Redraw part of a web page or slide in your usual style.

  • Teaching materials

    Start from a photo or diagram to request line art or a coloring page.

  • Blog and social images

    Reuse saved instructions to request thumbnails.

  • Compare ChatGPT and Gemini

    Use the same image and instructions in each. Gemini also lets you choose an aspect ratio.

Development story

What prompted it

I often generate images with ChatGPT and Gemini. I got tired of attaching an image and entering the same prompt each time, so I made something to make that work easier. I also wanted to try building a Chrome extension.

What took work

Just after I released it, ChatGPT changed its interface and the process began stopping partway through. Once I fixed that, the check for whether a message had been sent stopped working properly. Building something unfamiliar brings its share of surprises.

What matters to me

I did not set out with a particular design principle, but it has made my own work easier, so I count that as a success. It may suit a fairly specific way of working, but I think it could help others who repeat the same steps.

What you need

  • Google Chrome 120 or later (developed and tested on Windows 11).
  • Signed in to ChatGPT or Gemini in Chrome, with an account that can generate images. Usage limits and plans follow each service’s terms.
  • No API key, extra software, or PicPreset account is needed.
  • ChatGPT and Gemini change their screens from time to time, so what you see may differ from the guide.
