Flashcards for your terminal


note: I haven't developed it much the past months as I now have my first developer job so been busy on that and other stuff.



Click to download binary

It will probably be flagged as dangerous by windows


Package is simply named "speki" in the aur. Can be found here.

if you're using yay:

yay -S speki

Linux binary

Click to download binary You'll have to add it to your PATH manually for easy access. I'll look into how to to package it for various package managers, if you have experience with that then I'd appreciate help.


For something that will work on any distro as long as you have cargo installed, try this:

cargo install speki

Note that this won't install all the necessary dependencies, for example look at the note on ubuntu right below. You can get cargo by installing rust


If you install with Cargo, you will also need to install the following package: libasound2-dev


If you install with Cargo, you will also need to install the following package: alsa-lib-devel
--> sudo dnf install alsa-lib-devel


It's not just about having flashcards in your terminal


Speki has integrated the shared decks from anki, meaning you can jump straight in to learning different things, all without even leaving the app. It also allows you to customize the templates before importing. Soon I will add the possibility to add your local anki-files so that you'll get your anki-cards together with their learning-history to Speki.


Have a question but you're not able or don't have the time to find the answer to it? You can add unfinished cards in Speki, and be periodically asked if you're able to find the answer to them. No more needing a separate note-taking system for things you want to turn into flashcards.

Knowledge dependencies

You have the answer to your question, but you don't understand the answer? You can add the card as finished, but add dependencies to it, which would be other cards you need to understand for the current card to make sense.

For example, if you read this and you want to memorize it:
Alpha particles consist of two protons and two neutrons

Let's pretend you don't know what protons or neutrons are. If you were to memorize this sentence in that case, the knowledge would be completely useless to you. In speki however, you can add the two following cards as dependencies:
What is a proton?
What is a neutron?

If you add them as dependencies, the original card will be marked as unresolved, meaning it has unfinished dependencies. When it is unresolved, you will not be asked to answer it, but you'll be asked to learn what a proton and neutron is, when you've figured out their meanings, the alpha particles card will become resolved and you can review it as normal. This system ensures that no matter how complicated things you add, you'll never end up memorizing something you don't understand, as long as you mark your dependencies correctly.

It also works recursively, meaning in the previous example, if you found the answer to "what is a proton" but didn't understand it, that card would itself have dependencies. The dependency-graph could go on indefinitively, but if you keep on the dependencies would eventually all resolve and you'd finally learn the top-most card. This closely mirrors how your brain works, as everything you know is dependent on other pieces of knowledge. It also eliminates the need for making mind maps, as this is basically a more accurate type of mind maps.

Incremental reading

Incremental reading is a concept originating in SuperMemo. It allows you to incrementally work your way through countless longform-texts in parallel, where you'll learn and memorize everything you want from it. This is done by by being presented with the texts within speki, and every time you see an interesting piece, you take extracts from it. As if you were going through a real book and using a highlighter. Later you'll be presented with just the extract, and here you can choose to make further extracts, or directly making cloze deletions by marking the things you want to remember. When you read a non-fiction book, not long after you won't remember much from it. If you do it through incremental reading, you'll remember every single thing you choose to remember, albeit with some extra efforts.

If you want to read more about incremental reading, you can check out this blog article, as well as many other articles from the same site.

OpenAI integration

Future plans

  • Add tab where you can browse and filter all cards and perform actions on them
  • Add image suport for terminals that enable this
  • Machine-Learning algorithm for spaced repetition
  • Visualize dependency graph
