I taught a local vision model to find the same AliExpress item cheaper — variant and shipping included

Description and use

The pricehunt Chrome extension uses a local MiniCPM‑V model to compare images and product options on AliExpress, automatically finding the cheapest offers that match the selected variant and include shipping costs.

Problem

The price shown in AliExpress search results rarely reflects the actual cost of the desired variant plus shipping, forcing users to manually open many tabs to compare prices.

Outcome

On a test case, pricehunt found the same Essager 33W charger for $8.42 (free shipping) versus the original $12.43 listing, and outperformed a manual search that found $8.89.

Workflow

• Open the desired product page on AliExpress
• Select the specific variant options (power, color, plug, size, etc.)
• Click the "Find the same thing cheaper" button in the extension
• The extension searches listings by image and title, checks each option, and compares prices
• It displays a side panel with listings, showing item price, shipping, and whether the match is exact, similar, or different

Evidence

The extension then diligently searches AliExpress like someone would, by picture, by the seller's title, clicking on the listing one by one and checking all the options.
