I'm a little behind on this, simply because I planned to do it nore justice than a quick link post like this one. Best laid plans and all that. This is great news for Alfred users, Zapier opens up an already powerful automation utility into an unparalleled beast of an app. The article on the Zapier blog has a good run down of how you might use this. Given time, I will try for a deep dive, and post some workflows.
Picking up where I left off with the first Mac automation post; we covered some of the more well known Automation utilities on macOS in Text Expander, Automator, and Hazel. To be fair, at least one of the areas I cover this time around is likewise pretty well known, but I also want to highlight a couple of unique utilities that qualify as automation tools. These tools have both explicit and implicit utility for study, research, or indeed any academic related workflows. As with all such suggestions, the limit to what you can do with this kind of software will be somewhere between what you can dream up, and how much time you are willing (or able) to sink into them.
Popclip is one of those apps that highlights a gap in design reciprocity between iOS and macOS. We have always had the right-click  context menu to access functionality in OS X or macOS, but Popclip brings an interpretation of the context menu from iOS back to the Mac. The need to port contextual functionality such as copy and paste to the iPhone and iPad led to the creation of the ubiquitous black speech-bubble that appears from a long press on those devices. Popclip takes that idea, brings it to the Mac, and makes it extensible with customizable actions. I have become so used to using it that if ever I’m on a Mac without it I get a little lost. I use it for text transformations , Shortening URLs, dictionary and thesaurus lookups, adding tasks to my task manager, adding links to Pinboard or Instapaper, adding references to Papers, translations, and the list just keeps going. This link will take you to the pre-packaged extensions that are available, but the good news doesn’t end there. Not only will a Github search reveal many more ingenious uses for Popclip, and you can even code your own.

Alfred, Launchbar and others (…but mostly Alfred)
A lot of Mac nerds would argue that a Launcher is the purist’s starting point for workflow automation. If you want to keep your hands on the keyboard, then using a launcher is essential. Spotlight has developed well beyond its basic search capabilities in the past few years to the point where, although still relatively basic, it is much more than a mere search engine and application launcher nowadays. What’s more, Spotlight comes baked right into macOS, so a lot of people will find that hitting command (⌘) space will allow you to do a lot more with the keyboard than you realised.
Going beyond Spotlight to incorporate automation is where the best third-party launchers excel. As far as which launcher is the best? That honestly depends on who you talk to, but there seems to be a fairly solid consensus that the contenders are LaunchBar, and my personal favourite Alfred.
Both LaunchBar and Alfred are limitlessly extensible; LaunchBar with Actions and Alfred with Workflows. It is difficult to say how one might choose between them , but you may find the keystrokes for one, or the other, more intuitive for the way you work. Other than that admittedly abstract and vague selection criteria , it is fair to say the user community around Alfred appears much more engaged and accessible. Both the official site and forum, and the unofficial Packal site, are loaded with workflows, advice and friendly automation ninjas willing to help you down a rabbit hole, or back out of one.
Again, I use Alfred for all kinds of things. The screenshot of my workflows is only part of the picture. Searching my Papers library, converting documents with Pandoc, searching my Pinboard bookmarks, making currency conversions, task management input, natural-language entry of calendar events, time-stamping notes, Image Optimisation, file management. Alfred is an onion, and in reality I have barely peeled back the first layer. There is a built-in clipboard manager, and text-expander style snippet function. Anything that you can automate via scripting can be triggered via a launcher like Alfred or LaunchBar, which means they capable of all kinds of complicated tasks. As a bonus, they can manage the simple things too, I even lock, logoff and shutdown my Mac with Alfred – and Alfred also has an iOS remote app that allows me to control my Mac from my iPhone or iPad.
These are not the only two apps of this kind, of course. There are die-hards still using the OG launcher, Quicksilver, and given it is open source and free, for some it remains worth a look. Another old favourite of long-time Mac users is Butler, from Many Tricks. There is the lightweight Launcher  from Nulana, which is reknown for its advanced calculator and script launcher. Finally, a couple I feel are worth keeping an eye on, the open sauce Zazu App that bills itself as an extensible launcher for ‘hackers, creators and dabblers’, and perhaps the most interesting new app in tis area Lacona, a natural language launcher built on Node.js that already has web automation triggers through IFTTT. 
Dropzone is another extensible utility that can thread automation actions into your workflow. Another example of an app that is incredibly useful even in its most basic use cases, or can be bent to one’s will with a little ingenuity. The basic premise is very simple, Dropzone is a menu bar app that extends the drag and drop capabilities of your Mac, it houses destinations and automation actions on the ‘drop zone’. You can use it to hold, copy or move files between apps , configure it to upload files to cloud services or an FTP server, or social media sites. The real power of the app lies in the customisable actions – I have scripts for renaming files, stripping formatting from text, making animated GIFs, shortening URLs, and so on – but Dropzone also makes for an excellent conduit to other parts of your system. For example, as part of my workflow for posting images to this site I will take a screen shot and drag it to the images folder configured in Dropzone, from there Hazel will invoke an Automator workflow  to resize the image, then pass the file to ImageOptim for compression and removal of personal metadata. I could easily automate the whole process, but I don’t want every single screenshot I take sent to the same place, so Dropzone allows me to have a little more control over the file picking.

Such as capitalisation, Sentence-case for formatting titles, clearing formatting, hyphenating etc ↩
Some people solve this by using them both, but I’m yet to find something I need LaunchBar for that I can’t do with Alfred ↩
And the fact the Alfred’s developers have a commendably irreverent name Running with Crayons ↩
Rather than using the command line ↩
Yes, an imaginative name that ↩
This might sound silly, but for anyone working with fullscreen apps or split-screen it is seriously handy ↩
