E-commerce Side-to-side

Creates side-by-side product comparison tables extracting data from pages (Amazon, Walmart, AliExpress and almost any generic website detecting tables with specs), and allow to send to AI (*) to help select the best product (along with online information pulled by AI).
Add products by pasting links, right-click on websites or auto-detect from open tabs.
We'll also suggest similar products below and save the most recent you added to allow you re-adding them.

(*) BETA version from Oct 2025, giving instruction to copy and paste to any AI, or to directly send to Mistral (needs to be logged). More will come soon.

Say goodbye to endless scrolling and tabs – our extension simplifies the process of finding the best product for your needs.

✓ Functionalities:
- Show product side-to-side with title, price, main image, color, weight (all the ones present in the website page). Sort by value horizontally and vertically;
- AI instructions to paste into ChatGPT/Claude and get a summary of differences.

✓ Price
The extension is FREE to use to compare up to 3 items. You can subscribe to a premium plan (few dollars a year, via Stripe) to remove this limitation, export to CSV, and have product links bringing you directly to Amazon instead of our website.

✓ Permissions
We need permission on all the websites to add a CONTEXTUAL ITEM (right-click), to open e-commerce webpages in the background (only the ones you clicked), and also permission to store into your BROWSER storage (only for yourself) the products and notes you selected. If you click on "remove" on those products, all of them will be wiped.

✓Privacy Policy
The product you selected and the note you added are exclusively stored in your browser cache ("chrome storage") for performance reasons (avoid re-downloading) and can permanently deleted if you click "REMOVE" above each product.
We do not send any data to our server nor any other parties. The extension has no permission to contact any server except the e-commerce websites when you click on the product, to exclusively grab the information and present them to you in the comparison.
