Polar Anki

Posted By admin On 18/01/22

What makes Polar special is that we’ve built an integrated workflow so that you can read, annotate (make highlights, add comments, pagemarks etc), and convert anything to flashcards. You can then use spaced repetition to review your material directly in Polar or sync it to Anki. Anki 2.1.6 2.1.7 changed it's app domain name, so if you want to change the app nap for anki 1. Start the Terminal application. Execute the following commands in the terminal window: defaults write net.ankiweb.dtop NSAppSleepDisabled -bool true defaults write org.qt-project.Qt.QtWebEngineCore NSAppSleepDisabled -bool true 3.

Anki sync in the next version of Polar is being refactored to sync all documents in one batch.#polar #pdf.

  1. Polar Anki
  2. Polar Anki Addon
  3. Polar Anki

This allows you to sync flashcards created from annotations directly to Anki.

Polar supports a robust annotation system internally with features like text andarea highlights, and allowing comments and flashcards to be attached directly tothe highlights.

The key advantage is that this systems not only creates flashcards but keeps context associated with theflashcards.

The context is important. When using spaced repetition you don't want to forgetthe context in the future. You might forget about a topic or want to reviewand knowing the context is extremely important.

To get started, you need to add Anki Connect as an add-on in Anki. See deatils in the link but in essence, all you need to do is add Anki Connect's code to your add-ons within Anki.

Once that's done, you can sync all your flashcards to Anki by clicking the 'Start Anki Sync' in the top right corner of the app. Syncing only works from the desktop app, not from the webapp

By default Polar stores all Anki cards in the 'Default' deck.

You can change the deck per document by setting a tag with a deck: prefix.

For example, if you want to store things in the 'Technology' deck you justtag the document you're reading as 'deck:Technology'.

NOTE: In Polar versions prior to 1.8.0 we used a 'deck per doc' strategy wherea new deck was created per document. Not many users liked this and we removedit in 1.8.0. Technically it's still supported but needs to be re-enabled.


We now support sub-decks and these can be done with deck:compsci/linux forexample with a forward slash building the sub-deck hierarchy.

We replace it with the internal Anki :: but in Polar we want to keephierarchies represented by a forward slash.

Both cloze deletion and front/back card types are supported.

Cards also support rich text formatting (bold, italic, etc) as well as images.

Install the Anki Connect add-onand restart Anki. At this point Polar can sync to Anki properly.

Once Anki Connect is running, go to the overflow menu to the right in the navbarand select Start Anki Sync from within the Document Repository.


If you have any issues connecting Anki make sure you don't have a firewall inplace. Anki Connect runs Anki on a specific port and Polar needs to connectvia TCP to sync your flashcards.

International Users!

*IMPORTANT If you're using an non-English version of Anki you have tocreate note types for 'Basic' and 'Cloze' otherwise sync will fail. Changingthe language doesn't re-create the note types unfortunately. We're workingon a fix for this issue.

  • No current ability to update flashcards. Polar currently lacks a flashcardupdate UI so this needs to be added to Polar before we can implement this inAnki sync.
  • Anki must have Anki Connect. This will always be a hard requirement, but wemight create a Polar Sync plugin for Anki.
  • No support for nested decks. Each deck is created at the root. If you move itthe new deck will be created. We will have a fix for this in the future.
  • All flashcards are always sync'd each time. This is probably going to be slowerfor larger decks but we plan to implement differential sync in the future.

Maybe now somebody can connect GoldenDict with Anki so that GoldenDict also looks up words in Anki collection.

This is awesome ~I'm learning Korean it really help me. I think it would be great if you add it to Morphman to let Morphman process the Korean context like this Japanese plug in: MeCab UniDic Japanese Dictionary (https://ankiweb.net/shared/info/13462835). It supports Morphman. Thank you so much

Thank you very much. It's a fantastic tool for learning languages!!
At this moment, using the AnkiConnect addon, the Back Template of the card is not created well. But you can edit it and copy it from here: https://github.com/dobladov/youtube2Anki
I prefer to work on my listening, so I removed this two lines from the Front Template:
And put in the Black Template:

Makes anki run slowly for me, but this is yomichans fault. I have a large deck and it might be related to yomichans duplicate check
Had to start anki with Shift key held to disable all addons, then disabled ankiconnect. Everything besides ankiconnect is working fine now.

For Mac User
Anki 2.1.6 2.1.7 changed it's app domain name,
so if you want to change the app nap for anki
1. Start the Terminal application.
2. Execute the following commands in the terminal window:
defaults write net.ankiweb.dtop NSAppSleepDisabled -bool true
defaults write org.qt-project.Qt.QtWebEngineCore NSAppSleepDisabled -bool true
3. Restart Anki.

I use this with Chrome Yomichan extension and it works great. Has worked well since I first installed it over half a year ago. Thank you for the awesome add-on :)

Love this plugin.. We use it with Polar to sync flashcards form PDF books directly into Anki. You can read your PDFs and HTML content in Polar and create the flashcards there and then we use Anki Connect to transfer them to Anki.

Polar Anki Addon

on 1541305555
Great add-on. One drawback that I don't know if it's the fault of Anki or the add-on:
I can't figure out how to make fields keep new line characters when sending them to Anki. Adding both n and rn to the field doesn't result in Anki breaking the text up into lines.

Thanks so much!! This plugin helped me write this Hammerspoon Spoon https://github.com/ldanilov/AnkiShortcuts to add notes with simple shortcuts.

Great app!
And I'm so happy that there's a firefox extension. I've always been using chrome since I assumed the more niche extensions would never make their way to firefox. But this is the only 'killer' extension I need, and I didn't even check if it was on firefox lol.
Cheers for the good work.

This is the add-on that's been keeping a bunch of Anki-related Google/Firefox ex
Not sure it the author would see it or not, but thank you for your work!
As a code-dummy,I don't know whether this is a beautifully written py. file or not, but sure to say that without it, a couple of Anki extension would be at great trouble.
