Cart Keeper is a lightweight Chrome extension that lets you save products from online stores into one local list. It detects product pages, saves the name, price, image, and link, and keeps everything in your browser.

AI-native CRM that builds itself and does work for you

Hey Product Hunt, I built Cart Keeper because I kept losing products I wanted to come back to later. The usual flow was messy: browser tabs, bookmarks, store carts, screenshots, notes, and sometimes spreadsheets. None of those felt like a good place for “I’m interested in this, but I’m not ready to buy it right now.” Cart Keeper is my attempt to make that flow calmer. It is a lightweight Chrome extension that lets you save products from online stores into one local list. It saves the product name, price, image, link, store, and last saved date. If you return to a saved product later, you can update it, which is useful when the product details change. A few things I cared about while building it: - no account required - no backend - no analytics - products are stored locally in the browser It is still early, and I would love feedback from people who often save products for later: car parts, electronics, tools, furniture, hobby gear, gifts, home items, anything where one tab quickly becomes twenty. Would love to hear what stores or workflows you would want it to support next.

A small note on privacy: Cart Keeper does not send your saved products anywhere. The list is stored locally using Chrome storage.

The goal is not to replace wishlists or shopping carts. It is more like a temporary, cross-store “thinking cart” for products you may want to compare, revisit, or update later.
