Can add many features for this. Some low hanging fruit:

• time tracker: recognize which application is running, and track time usage, together with some metadata, and allow to jump to that point in time
• use NLP to do named entity detection and part-of-speech tagging, to add some metadata to the screenshots and maybe connect them to each other and to known entities. e.g. can build an "automatic CRM" with this, which needs no integrations (!!!!).
• integrate with information from the hard drive and from network traffic, to get more context on activities. (if we're upping the "spying", we can even use a keylogger but that doesn't seem useful for anything.)
• can do special treatment of various applications, e.g. the browser, various API integrations, etc. . This goes against the "spirit" of the tool (which is that since we as users interact with the screen, then the screen should have all information that we need, if we just process it well enough. But it's interesting.)
