Shopping online always left me with the feeling, I might pay too much for the same product as a result of being spammed by google ads, SEO and the likes. At the same time, I have spoken to 50+ online shoppers about their experience with price comparison sites and this is their feedback:

1. Not all products and shops are listed on price comparison sites.

2. Prices are often outdated. In fact, it turned out that e.g. the 10th best offer on a price comparison site is actually the cheapest.

3. Users have to manually check whether the better offer is exactly the same product variant as the sought-after product. This is extremely time consuming when checking for technical specs of e.g. a gaming PC.

I have just finished my PhD in AI and that is why I decided to solve these problems.

The price search is live under the link: https://josepha.io/en
It works for the currency areas USD, CHF and EUR.

It works with the following two steps:
- First, insert the product URL of a product you are about to buy
- Second, insert the email. The results will be sent to you via email, after the search was processed.

After you submit the product URL, it searches the entire web and determines which other shops offer the exact same product.

Some statistics up until now:
- Savings found: €29'264.01

- Total Search volume: € 297'424.49

- 50% of all single searches save more than € 6.07

I would greatly appreciate if you give it a try and comment with feedback.

I have been searching grocery and personal care prices item by item to compare Kroger to Meijer (this are my only real options). Has anyone found a quicker way they would be willing to share? I could go to Aldi as well. I have looked at some apps to download but most seem pretty sketchy about info gathering or what they actually do. Having to keep typing to meet the 300 character limit so please pardon the run on sentence.
