Writing my Notions and notes these past months as part of my revamped personal knowledge management system, I realised as the collection grew that using the collection as a thinking tool also requires remembering more of what is in there. Not to make the notes superfluous but to have more top of mind material that serves as a starting point in interacting with the notes I have, as well as to be able to weave that more easily into current tasks and work. I also expect it to aid creativity, as a large chunk of creativity is recombination of previous elements, and remembering more elements lowers the threshold to new combinations.

Both in Andy Matuschaks notes and in this long article by Michael Nielsen about his use of Anki, spaced repetition is discussed in the context of note taking, and it got me thinking (I write ‘thinking’, but it was as much working through the mentioned material and distilling the concepts key to me from it, as it was chewing on it mentally and adding that to those same notes. Thinking is more interacting with my PKM, rather than sitting down looking into the middle distance as per Rodin’s bronze).

Anki is a tool (on laptop and mobile), that allows you to train your memory with flash cards and spaced repetition. I’ve used it in the past, e.g. to increase my vocabulary in French and to better read cyrillic script, but not with much energy or effect. It felt uncomfortable to be using card decks made by others for instance. Making my own flash cards from scratch always seemed a daunting task as well.

With my now much better set-up of notes however I have a great starting point to create my own decks of flash cards. As I am obviously not the first one to realise the potential of notes collections for flash cards, there is already an Obsidian plugin that pulls out questions and answers from my notes, and puts them into Anki. It comes with a wiki that documents how to set it up for yourself, including how to mark various types of questions and answers in your notes.

The key feature is, that I can add a question and its answer as a part of any note, and the plugin will pull it out and export that to Anki. It means I can e.g. end a note on three key aspects of distributed applications, with an Anki question and answer about those three aspects, which will get exported to Anki. Better still, I can add multiple questions in different forms about the same thing to that note, e.g. a follow-up question for each of the three aspects. Having multiple versions of basically the same question means I can phrase them for different memory hooks in parallel. This will enhance my own understanding, and allows me to place notions in specific contexts for instance.

I have now installed the Obsidian to Anki plugin in Obsidian, and the Anki Connect plugin in Anki (so it can ‘listen’ for automated input).

Some things I hope this will yield benefits for is:

• making it a more deliberate choice what I want to remember long term
• making it easier to remember the basics of a new field of interest
• making the effort to remember a habit
• improving my skilled reading
• using remembered material to better connect new notes to the existing corpus
• making it easier to internalise new / relatively new material

The way I’m approaching it is to have all my flash cards, whatever the topic, in the same single deck. This as I see my notes collection and all the stuff I remember as a interlinked network of topics and material. Splitting it up in some sort of thematic structure precludes a whole range of potential connections and associations, and is artificial in that it makes a current perhaps logical distinction the norm forever.

The coming 12 weeks or so I’ll work on two habits:

• adding questions to my notes as I work on those notes, and
• using Anki daily to review those questions.
