โญ๏ธ Mark commented on our Reddit: โ€œI've been like a kid in the candy store as I'm building extensions on almost everything... Here are a few of my latest: * Added a button that will summarize the main question and give the "vibe" of the group's answers for questions posted on a financial advisor message board * Grabbing data from website tables and saving in a CSV file format * Add a button that finds and saves all phone call recordings (GoTo) that are more than seven minutes long (requires clicking into various areas) * Added a button on a financial graphing program that creates an email that summarizes the chart in plain language, and copies the summary to the clipboard My prompting has been very relaxed, but I've been happy with the generated tools. I'm sure my prompting will get more specific over time. I've not had too many ideas that were complete flops.โ€

โญ๏ธ Piknockyou left a 5-star review on the Chrome Web Store: โ€œAbsolutely brilliant extension. It worked like a charm in 1-shot to scrape comments and replies on MyDealz.โ€
