This is just a text description for the store listing — I'll draft it directly rather than creating a doc file.
Here's a description tailored for your add-on that's distinct from the competitor's:

Short description (for the store listing summary):

Remove image backgrounds instantly in Google Slides™. One-click background removal — no Photoshop needed.

Detailed description:
Remove Image Backgrounds is the fastest way to remove backgrounds from images directly inside Google Slides™ — no switching tabs, no uploading to external websites, no Photoshop required.
Select any image on your slide, click one button, and get a clean, transparent background in seconds. Background removal works on photos of people, products, animals, logos, and more.

✦ HOW IT WORKS
Select one or more images on your slide, open the sidebar, and click "Remove Background." The add-on processes your images and replaces them in place — same position, same size, transparent background. That's it.

✦ PERFECT FOR
— Pitch decks & presentations: Drop in team headshots or product photos and remove backgrounds for a clean, consistent look across your presentation.
— E-commerce & marketing: Create professional product images with transparent backgrounds without leaving Google Slides™.
— Education & training: Teachers and students can quickly clean up images for class presentations and projects.
— Social media content: Prepare images for posts, stories, and ads without needing design software.

✦ WHY THIS ADD-ON?
— Works inside Google Slides™: No need to leave your presentation or use another tool.
— Batch processing: Select multiple images and process them all at once.
— AI-powered accuracy: Handles complex edges like hair, fur, and transparent objects.
— Fast: Most images process in under 5 seconds.
— Simple: No settings to configure, no learning curve. One button does it all.

✦ PRICING
Your first 25 images are completely free — no credit card required. After that, upgrade to Pro for $9.99/month for unlimited background removals. You can manage or cancel your subscription anytime from within the add-on.

✦ PRIVACY & DATA
We take your privacy seriously. Images are sent to our processing server solely for background removal and are not stored, shared, or used for any other purpose. We do not access your Google Slides™ content beyond the images you select for processing. No data is shared with third parties. We comply with GDPR and the California Consumer Privacy Act (CCPA).

✦ TROUBLESHOOTING
If the sidebar appears blank or the menu doesn't load, try logging out of all Google accounts and signing back in with just the account you want to use. This is a known Google issue when multiple accounts are active.
