For me, Devonthink serves several different purposes, each of which I used a variety of different tools in the past.
1: Archived Correspondences
These are any letters, emails, calls notes, etc. that I send and receive not for my business(es). They include insurance documents, bank statements, utility bills, etc. The way this is set up is all files are placed in the Mac filesystem in ~/Documents/AC/
so it gets sync’d to iCloud and I have access to them on my other machines. The files and folders are then indexed in DT3.
This used to be in Evernote, but I realised that if someone got hold of my files (e.g. because of a hack), they would have access to my life.
2: Business Network CRM
Here I collect all of my correspondences with, and notes on, people I interact with for a business purpose. DT’s ability to easily archive emails is key. If I create an office document (Powerpoint, Excel etc) for that person, I keep it on my Mac’s file system and I index it in the correct group. Hence I never need to find the file again in Finder once I am looking at the right group in DT3.
Better still, I use DT3 to set reminders, for instance just before I have an upcoming meeting: an email is sent by DT3 to me with a link to the relevant document/group.
I used to use Highrise for this, and to some extent the notes section in Contacts
and even Day One
. (Yeah it was a mess.)
3: Business Projects
Like the CRM, the ability to just collect all sorts of different files (indexed or not) and tag them, is what makes this useful. It becomes the nexus for files and emails that are all over the place on my Mac(s). Linking is super useful, I can link projects to people in my CRM, and projects that are related to each other. Sometimes I create smart groups based on tags for a project and delete it once the project is done.
I used to use email, the Finder
's tagging system and my memory for this. Things got lost all the time.
4: Research
I read research papers, and while I don’t write articles for peer-reviewed academic journals, I do write and publish articles (and of course, blog). Here DT3 serves the purpose of archiving academic articles, websites, newspaper articles etc. The power is in the tagging and linking. I not only tag material with subjects and keywords, but also the title of the article I have written/is working on. Much later I can retrace my steps when I’m trying to figure out how I got an idea.
DT3’s ability to make annotations and create a special annotations file with backlinks to the original document allows me to organise my notes. The Zettelkasten method does not really work for me (I have tried it, and for me Obsidian was a better tool for a slip box).
I used to use Evernote
for note taking, and frankly, dropped PDFs all over the place and kept links to web articles as Safari Bookmarks. Everything was distributed all over the place and I relied on Spotlight
. DT3 just brings everything together and I can look at connections thematically or through keywords, etc.
I generally manually format my citations, so there is no real need for a reference manager. (However, it’d be nice if I could extract and store a paper’s metadata and press a button to generate a bibTeX
citation.)
5: eBooks
Related to the above is how I store my eBooks. I have many non-DRM technical eBooks (epubs and PDFs) bought over the years. They are in a monolithic database that just uses tags.
The power in DT3 is in search in this case. It allows me to find all instance of a search term in the books (at faster than spotlight
speeds). DT3 can take you to each instance, highlighting the occurrence of the search term. It hence helps with my research.
And if I find a section useful, I can make an annotations file. Also I tag the book with the project name, or title of the article I am writing so I can quickly find it again.
I used to use Books
to store my eBooks. Needless to say it’s not as useful as you can’t search inside a book without opening it first.
6: Commonplace Notes
My interests spans many subjects. As I read, I write notes in DT3 and link them to articles and books that I have collected in 4 & 5 above. This only really started when the developers introduced MathJax support. Also, if I need to quickly draw a sketch, I perform an “insert from iPad” and use the iPad to make my diagram.
I used to use all sorts of note takers for this – Evernote, Apple Notes, Notability, etc. Now it’s all in one place and not locked inside a database exportable only in JSON or HTML/PDF.
7: Writing Projects
Because I collect research material in DT3, I also start my manuscripts in DT3, first creating a project group and tag. That way, everything is together. Since I work on multiple things at any one time, it makes things more efficient when you come back to a project as everything is in one place.
I don’t necessarily use DT3’s interface to write with. I prefer iA Writer
and MacVim
depending on what I am writing. It is easy enough to get DT3 to open a document in the app of your choice (well, not all apps, but ones that can read and write files in the filesystem as opposed to using its own database, such as Bear & Scrivener).
I used to use Scrivener & Ulysses for research & writing, but the research I collected this way was stored specifically to the manuscript and hence was siloed away. With DT3, it’s the opposite. Research is a large tagged pool where I pull things out and link to projects.
8: Tech Journal
I keep a tech journal of all my machines: faults, installs, problems, solutions etc. Here, it’s the markdown editor and WikiLinks that shine. I can link instances where I have seen similar problems on other machines or in another time with [[ ]]
. I can also link to websites where the issues/solutions are discussed. I depend on the “created date” to create a timeline to trace faults sometimes.
I used to use Evernote, then Day One for this.
9: Trading Journal
This is a hybrid of archived correspondence and research. Every trade/investment I make has a bunch of research, reasoning and talking to mentors and peers behind it. I take screenshots of charts for my notes, along with relevant news articles, SEC/other regulator filings etc. All these go into DT3 in a monolithic database that is tagged.
And when a trade is executed, I collect contract notes or screenshots of instructions. My analysis in spreadsheets are left on the filesystem and index
ed as well.
Believe it or not I used to use Day One for this.
TL;DR
The strength of DT3 is that it enables me to collect information from various sources in various formats easily into data lakes. Files collected are not molested but instead a whole host of metadata are associated with the files. These metadata go beyond what the Finder can do.
While you could in theory use the Finder to just store a lake of data, and tag them using the Finder’s tagging system, you are losing out on a the ability to link documents together (e.g. by Wiki Linking, copying DT links) and you have to admit, organising the Finder’s tags sucks once you have more than a handful.
You would also lose out on many time-saving features such as renaming files from selected text and creating tags from hashtags in text. And you’d lose out on powerful automation and smart groups, to create temporary groupings of disparate data.
You would also miss the powerful search feature, where you can search across databases and within PDFs and epubs. You would also miss the “See Also” feature that shows you related files to the one you are looking at, through DT’s pattern recognition algorithms. This helps you find serendipitous links and connections.
DT3 is really a platfom that you can use to create solutions for your knowledge management problems. It is deep. Like any complex tool (e.g. emacs
or a computer language), the more proficient you get at it, the more things you can use it for.
And it does not lock you into any proprietary format. You can get back the original files and dump them into the filesystem with ease (for files that have not been index
ed).
Hope that helps!
