Pentive VS fsrs4anki

> I wonder what the ecosystem would look like if things were otherwise.

Shameless plug - I'm building https://github.com/AlexErrant/Pentive which is basically GitHub/Reddit for flashcards. Very much pre-product and a WIP, though the offline client proof of concept is done.

I also enjoyed the Treesitter talk from 5 years ago by Max Brunsfeld https://www.youtube.com/watch?v=Jes3bD6P0To

I'm currently building a query language whose grammar is very much inspired by Github's search syntax. I'm using Lezer, which is a GLR like Treesitter, so this talk learned me some parser generators (I've no formal CS education). Here's my grammar, a playground, and an example search query if anyone wants to play with it

Not really. There are options for sharing cards on Anki https://www.reddit.com/r/Anki/comments/14j2jfy/deck_sharing_... but their collaboration features are limited.

I myself am building an Anki clone https://github.com/AlexErrant/Pentive with collaboration built in as a first class citizen, though its far from primetime. Currently stewing on how to get the SR algorithm, FSRS, to compile to wasm.

A free, open source, local-first, spaced repetition system that works offline, has p2p syncing, plugins, and first class support for collaboration. It's GitHub/Reddit for flashcards.

I basically took Anki and turned it into a webapp >_>

I find Solid's model pretty damn close to "compiling down to nothing". I chose Solid for my project because I wanted to support plugins that used other UI frameworks. I recently got a Svelte plugin working with the SolidJS router. I could probably make it prettier... but it's literally a call to Solid's `createComponent` with the Router and an anchoring div to which the Svelte component is mounted. Ezpz.

I'm also building an Anki clone (sigh) that I'm calling "Github for flashcards".

Very much a WIP, completely unusable, but I recently made a video demoing the technical proof of concept.

Anki, imo, already has an open algorithm (that the user can change via plugins), universal interfaces, and is "self-hosted". My eyes perked up at REST api, but it doesn't look like there's a centralized server that hosts shared cards, which is where my mind went.

I'm building https://github.com/AlexErrant/Pentive/ which is basically Anki + Reddit - people can optionally upload their cards for others to download, and the most popular cards rise to the top. It's FLOSS, offline-first, supports plugins and p2p syncing, and is very much a WIP. My proof of concept is almost done though, which demos the critical technologies in a secure way.

I'm using cr-sqlite right now in my Anki clone: https://github.com/AlexErrant/Pentive

It's basically an offline-first flashcard webapp. CR-Sqlite allows for incremental syncing.

With Anki (the app from which I'm taking my inspiration), syncing is _not_ incremental - basically it just copies SQLite files around. So for example, the app could be on an iPhone with cards a card `A` reviewed, but the app on an iPad could make changes to the template on which card `A` is based, and that's enough to cause a conflict - you must take changes from only the iPad or only the iPhone. (To be clear - Anki does have some incremental syncing capabilities - I'm picking an intentionally pathological example.) CR-SQLite will mean that everything is incremental, however.

Basically makes 3 way merges a breeze (or n-way merges, really).

A FLOSS, offline-first, spaced repetition system that has first class support for collaboration, curation, and plugins. It's Reddit for flashcards.

I've been thinking about this for a stupid amount of time... thinking that someday someone's going to improve on Anki. Finally got tired of it and said that person's me.

For note-taking specifically, I've tried everything from plain old pen and paper to more modern solutions like Evernote and emacs (if you can call that modern), but nothing I've come across really beats Anki.

Although its main selling point is as a program for flashcards with spaced repetition, it comes with pretty much all the features of a good note-taking app, like tags, easy to organize, synchronization across devices (you can set up your own server), good interface for searching through your notes (which are stored in an Sqlite db if that matters), and yes, LaTeX. Not only that, it's also highly extendable with third-party plugins, so if there are features that you miss chances are there's a plugin for it. In other words, you can use it perfectly fine just taking notes. However, where it really shines is in all of this in combination the spaced repetition algorithm, which is now on steroids with FSRS[1][2]. The downside is that for this to be effective for the things you want to memorize, you'll have to write your notes to be suitable for a flashcard, but if you do it consistently you'll soon notice that you can store most of your notes in your head (needless to say, any student would greatly benefit from this). Now, if that's too much work, you can still just use the scheduling to have it remind you of your notes. Either way, even as someone who sometimes goes out of his way to shoehorn everything into Emacs, I can't see a reason not to use anki for note-taking.

I recommend the new algorithm of Anki: https://github.com/open-spaced-repetition/fsrs4anki

It would be nice if you could report this on Github. You can do it here: https://github.com/open-spaced-repetition/fsrs4anki/issues/n...

As for randomly getting a lot of reviews, honestly, no idea. You should submit an issue on github: https://github.com/open-spaced-repetition/fsrs4anki/issues/new/choose

u/PoppingWebster, here's a guide on how to use built-in FSRS in the latest version of Anki: https://github.com/open-spaced-repetition/fsrs4anki/blob/main/docs/tutorial.md

You can watch AnKing's video and read this guide.

Detailed info here: https://github.com/open-spaced-repetition/fsrs4anki/wiki/The-mechanism-of-optimization

use FSRS tho

More information on the new scheduling algorithm:

FWIW I've been using it for the last 10 days and it's finally resolved some of my pain points about having to trial-and-error adjust the old scheduling algorithm, since the content of each deck can greatly affect what the optimal retention is. Now you can just retrain the weights for each deck you have and it will adapt appropriately. The paper is also definitely worth reading if you want to see some rigorous analysis of large-scale real-world spaced repetition science.
