These can be retrieved online from anywhere (not just the app) and is how I do it, way easier than you think. It basically comes down to&lt;p&gt;$(&amp;quot;.icon-button-children&amp;quot;).each((index, item) =&amp;gt; ($(item).click())) &amp;#x2F;&amp;#x2F; expand all items&lt;p&gt;$(&amp;quot;.LinesEllipsis  &amp;quot;).each((index, item) =&amp;gt; console.log(item.innerText)) &amp;#x2F;&amp;#x2F; record the stuff&lt;p&gt;on &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.walmart.com&amp;#x2F;account&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.walmart.com&amp;#x2F;account&lt;/a&gt;</text><parent_chain><item><author>six2seven</author><text>This is exactly what I needed and was thinking about building a similar app. But to be really useful and automated, there&amp;#x27;s a bit long way I&amp;#x27;m afraid.

Basically what I&amp;#x27;d like to build requires either (1) product recognition vision like Google Lens offers, or (2) a barcode scanner &lt;i&gt;and&lt;/i&gt; an extensive barcode product database. Both can be combined of course.&lt;p&gt;My solution would be to read frames from a smartphone&amp;#x27;s camera until a barcode is detected. This can be achieved with eg Firebase ML, on-device. If a barcode database lookup gives a product, put it on the in&amp;#x2F;out list. If not, send the frame to a product recognition vision service. This could be Google Cloud Vision AI, but they don&amp;#x27;t give you access to their product set that backs Google Lens.&lt;p&gt;Finally, provide controls to adjust the number of items on the in&amp;#x2F;out list&lt;p&gt;I thought about OCRing supermarket receipts too but these differ so greatly in layout etc. per country I figured it&amp;#x27;s not the way to go&lt;p&gt;Edit: Problem you run into as not all of this can be done on-device is privacy concerns of coursem just my thoughts on what interface I&amp;#x27;d like to have</text><parent_chain><item><author>six2seven</author><text>This is exactly what I needed and was thinking about building a similar app. But to be really useful and automated, there&amp;#x27;s a bit long way I&amp;#x27;m afraid.
