Watches the changes behind the numbers: it sets up watches on the company announcements, earnings, industry data, exchange rates and commodity prices you care about, and tells you each day what's new and the likely reasons. You can set conditions (a price falling below a level, a company reporting earnings) and it alerts you when they're met. Every week the changes are summed up in a sourced review in your knowledge base. It only organizes public information and never tells you what to buy or sell.

• Tell me when the euro drops below 1.10 dollars; I'm about to change money for a trip to Italy.
• Tell me when Tesla, BYD and CATL report earnings, with three sentences on what changed in revenue, profit and guidance.
• Every Friday evening, send me how copper and aluminum prices moved this week and the main reasons, with sources.
