I have peer-reviewed research on the efficacy of SRS in second-language acquisition and this should be everywhere for everyone and the fact that it isn't is both a scandal and an opportunity for learners who do use it to leverage that advantage.

I use it extensively in my teaching. The problem is deploying Anki on locked down networks can be difficult so I've built alternatives and hacks to let you deploy decks and school accounts, but making a full-featured web client would change all of this.

So maybe it's a good time for me to have also started one of my own that I'm temporarily calling libreSRS because I'm not sure of the new direction here.

The goal is to have a multi-user, multi-algorithm-capable, web-based system that exposes everything (especially uploading!!) to the web client.

It was a fascinating symbiotic between nerdy med students from all over the world and an obscure open source flashcard app that originally targeted language learners. I've been part of that community for many years and would have never foreseen this outcome but in hindsight it seems the best path forward for anki.

As a person with really poor memory, the entirety of my learning depends on this app. I'm worried :/

On the plus side, the actually good mobile Anki client, AnkiDroid, remains out of the hands of this potentially questionable new entity.

(AnkiDroid has always been run independently, which is good, considering the state of the iOS client, which has always been neglected.)

The community has been in a deadlock over making FSRS the default (https://github.com/ankitects/anki/issues/3616), and I wonder if this will lead to some resolution.

It seems like the core things that Anki needs are new user experience improvements, and algorithm updates. SM2 really shows its age as compared to other algorithms.

I'm an Anki user, on and off since 10 years or so, but was still confused. If I understood correctly, the entities here are:

- Anki, as set up by dae aka Damien, is like the brand name and desktop implementation with the spaced repetition algorithm

- AnkiWeb is what I thought this hub thing was. It's where you download decks

- AnkiHub is a third party (started by "AnKing", now 35 employees) who sells decks as a monthly subscription and has their content on the deep web (you need to create an account and agree to terms to even see a listing of what's there besides a few featured parts). This is who is getting ownership of the former two. Because they write that Anki will remain open source at its "core", I presume that means that things will, at best, stay stable rather than anything (like AnkiWeb the deck sharing platform) becoming open

- AnkiDroid is a separate open source project (an Android app). The corporation is hiring the main developer, but it's not yet clear to me whether they're just going to get paid to work more on AnkiDroid or if they're also getting other tasks

AnkiHub people seem kind of slimy in my experience (at least their leader, "The AnKing"). I hope they figure out a good leadership situation, and make stronger commitments to openness.

Anki is in a very solid position to be forked if anything happens, so even if this is bad news I have faith in the larger community.

I shared my thoughts as a veteran user and contributor to Anki, as well as a former AnkiHub team member https://youtu.be/13p0t8Tv-jw

Considering that anki can always be forked if development goes being hostile towards users I think this is a net positive. The most common complaint among new users is the learning curve and the UI. Both can be solved and Anki can flourish to the bigger level. I say this as someone who does 300+ cards every day.

> Absolutely. Anki’s core code will remain open source, guided by the same principles that have guided the project from the beginning.

Already caveating with the "core" code. Even without PE and VC, it's clear that a company with 35 employees is bound to take this in a different direction than 1 guy, and not a good one. If there comes a day where those 35 employees can't be sustained anymore by revenue, and the choice is between enshittification and shutting down/firing everyone, we'll see what happens. That's the big difference - such a decision was never on the cards, or at least much less likely, when run by a single person. Now it will be.

Big conflict of interests too. AnkiHub makes money from selling paid addons. No chance any of those will ever end up in Anki now.

Also not a good look that they immediately locked the thread in their most popular community.

Good on him, 19 years is a long time to carry the flame. Thanks for getting me through school!

>Will Anki remain open source?

>Absolutely. Anki’s core code will remain open source, guided by the same principles that have guided the project from the beginning.

>Anki’s core code will remain open source

Hmmmmmm. Could be benign, but... hmmmmmm...

Always a bit scary when an open source project changes stewardship like this, but I'm quite relieved to see all involved parties seem to be aware of the dangers and very much on the same page about not screwing this up.

Done right, commercial interests can often have a very positive symbiotic relationship with open source. Almost all the largest and best open source projects out there have substantial involvement from commercial interests.

I do think though that from a structural/governance perspective it's not a good idea for Anki to be owned by AnkiHub. Anki is a community project, not a corporate product, and while it sounds like the license will continue to reflect that, I personally think it would be best if the corporate structure did too. If Anki were spun out as an independent foundation (like Blender, Linux, etc) receiving most of its support and development work from AnkiHub, rather than owned outright, I think that would allow a much more robust governance structure than just having everything be under AnkiHub's direct control with some pinky promises about listening to the community.

I've started using LLMs to help with card creation, and reviewing historic cards. Its been increasingly successful, I still end up with cards tailored to me, and the card quality has gone up (as I've asked the LLM to look for other views/sources and to do associate research to produce high quality cards).

Having ability to bake some of that into the tool in a configurable way would be ideal, and I hope thats sort of path they go down.

I realise in meantime plugins are an option, but I've found the quality of plugins very mixed.

I discovered Anki 12 years ago while living in Japan. I was trying my hardest and absolutely failing to remember any of the Japanese I was studying. Maybe I was due for a learning-style renaissance for myself and Anki was just the catalyst, but it really made a positive impact on my life. More than just memorizing kanji on AnkiDroid during my commute, I just started to believe I could learn anything. I was starting to take my coding hobby more seriously at the time and hacking on Anki was a big part of that too. Thanks for all the hard work Damien and David Allison. I'm so grateful for the software you've worked on.

In other words: they have no clue what to do next (https://forums.ankiweb.net/t/ankis-growing-up/68610/2#p-1905...)

Anki is and was truly a blessing. Not sure I would have gotten through my studies without it. Thank you dae!

I love anki.

But upon reading this I think it's high time I exported all my notes in simple text format, just in case.

Maybe also try Fernando Borretti's flashcard app I saw (and dismissed) recently here

The best thing that can happen is a fork. There is no way this will make the app worse, at least if you use a phone to do the reviewing. Syncing is sure to become a subscription.

Even in the worst-case scenario, Anki is already perfect for me as is.

Looks like it's already going in the wrong direction.

"Our agreement with Damien stipulates that the current AGPLv3 code remains open source"

It sounds like a very specific dementi.

At a fundamental level the algorithms predict the probability of a learner to correctly recollect a factoid at a given point in time given a history of sampling that recollection / presentation.

It would be interesting to have machine learning predict these probability evolutions instead. Simply recollecting tangential knowledge improves the recollection of a non-sampled factoid, which is hard to model in a strict sense, or perhaps easy for (undiscovered) dedicated analytic models. Having good performing but relatively opaque (high parameter counts) ML models could be helpful because we can treat the high parameter count ML model as surrogate humans for memory recollection experiments and try to find low parameter count models (analytic or ML) that adequately distill the learning patterns, without having to do costly human-hour experiments on actual human brains.

I learned about Anki recently, and as I was told, this is somehow a standard on medical studies, where a whole bunch of knowledge must be memorised

In a nice and controlled manner, so seemingly no reason to panic just yet:

> I ended up suggesting to them that we look into gradually transitioning business operations and open source stewardship over, with provisions in place to ensure that Anki remains open source and true to the principles I’ve run it by all these years.

> This is a step back for me rather than a goodbye - I will still be involved with the project, albeit at a more sustainable level.

From AnkiHub:

> No enshittification. We’ve seen what happens when VC-backed companies acquire beloved tools. That’s not what this is. There are no investors involved, and we’re not here to extract value from something the community built together. Building in the right safeguards and processes to handle pressure without stifling necessary improvements is something we’re actively considering.

Relieved at that part where they say there are no investors involved, makes the whole thing a whole lot less risky. Good for everyone involved, and here's to many more years with Anki :)

People usually say they want to change the world, then there are people that just change the world. Thank you for Anki (heart)

I've used Flashcards Deluxe for years and been very happy (no affiliation):

Easy to import and export my cards, plenty of options for tweaking the algorithms for my use.

Oh for fucks sakes. No please no.

AnkiHub was already annoying with shoving AI into their Add-On without anyone asking for it.

I don't think this will go well

When a popular, free and open source passion project led by a single dev moves into the hands of a company that needs to sustain its 30-people team [0], you know what happens next.

AnkiHub's modus operandi has been to take over communities or projects where free exchange happens and monetize/paywall them. If you've been a part of the /r/medicalschoolanki subreddit, you know exactly what I mean. It's been hollowed out completely.

In the post, AnkiHub mentions how Anki is "sacred" to them. Yet, they have had no qualms entrenching themselves into Anki's settings menu as the only third-party ever to do so. [1] I am sure more is to come. And the language used in their post almost never helps their case, especially in the pricing and OSS sections.

I understand why Damien felt he was being a bottleneck in Anki's development. This is similar to what was happening with Bram and Vim. Ultimately, the community forked and built Neovim. Gorhill had also similarly transferred uBlock, but then came back and built uBlock Origin. So the precedents are there for a successful community-run or leader-run spinoff.

Syncing is sure to become a paid feature, and access to shared decks too.

Creating a fork pointed to a hosted version of Sync Server [2], and an alternative hub where people can share decks other than AnkiWeb [3] is paramount. As well as saving and preserving all of the decks there, as they are sure to go behind a paywall.

I, and I am sure many other HNers, would be willing to support that with our time and financially.

Andrew (the CTO of AnkiHub) is smart as a whip and has built an impressive and seemingly sustainable business. Seems like the ideal steward for Anki!

I feel like there's a lot of confusion, so not sure if anyone can clear up mine, but I'm really struggling to see a significance of this.

Obviously, like all ignorant people do, I am going to oversimplify things here. But still, to me, the "platonic idea" of Anki seems a dead simple thing. All what I care about when using Anki is what's on the 2 sides of a Card, a question + answer, which can only be some visual image (possibly encoded as text, possibly just JPEG, I really don't care as long as it fits in my mobile device memory) + optional sound. That's really it. If it should be bi-directional or uni-directional card is a detail of how the deck is generated/encoded, and the spaced repetition algorithm is a detail of the app that I use to study (so, usually AnkiDroid, I imagine — an unaffiliated 3rd party; who even uses desktop apps nowadays?).

So, I imagine there can exist (and do exist) some minor additional features, like an ability to require a typed answer for a card, but it seems pretty minor, and I really don't see a lot of room for the app to evolve.

So, ultimately people need only a common .apkg format, which exists and is relatively simple (although I suppose it could've been even simplier), and a place like AnkiWeb, where people can share their decks, so Spanish top-2000 or basic integrals deck isn't re-invented over and over again. It's a pity that AnkiWeb isn't more open and will be even less open from now on, but as long as someone is willing to just host it (which is ultimately just paying for downloads traffic) it's easy to replicate, so no super-valuable IP here.

Of course, a primary use-case for Anki is a tool to make decks, but you could really do with pretty simple python script + YAML/JSON/CSV/whatever metadata file to convert it to AnkiDroid-compatible .apkg file.

So, basically, who cares? What is to "own" there?

As someone who has used Anki for a decade, a thank you to dae for everything. Best of luck in your future endeavours.

With that out of the way, some thoughts:

- Anki is in a really good position to work around enshitification. The app, at least to me, is "complete" - the only additional features that might pique my curiosity is a different scheduler (at the moment, they're integrating a newer one, although I don't follow enough to know the state of it). Additionally, modern Anki is really well architected: the core of it is a Rust library, that is used by all of the platforms [0]. You can write new front ends using that, or just fork the existing FOSS ones. Maybe dae does a gorhill and gives us Anki Origin.

- Really the only service-y part of Anki I use is AnkiWeb, which is basically a backup and sync system. Wonder how that'll evolve (if they do end up charging for it, I hope it is "Obsidian" reasonable). EDIT: Ooo, Anki has public server software for running your own version. Awesome! [1]

- The idea outcome in my opinion would have been some form of charitable organisation (Linux Foundation?), with people donating to support Anki.

- So, AnkiHub is a company that produces Anki flashcards, and they've scaled that quickly? Jeez. Obviously Quizlet proved there was a market for flashcards, but I didn't realise this was possible for Anki.

- No outside investment is... hopeful. Not quite sure what indicates that this company has the technical know-how to maintain it.

- I've heard too many stories of a maintainer or creative being "hopeful" about their new acquirers, only to regret it years down the line.

Ugly over complex app for what it does. never saw the appeal

I always though Damien earns well with the iOS mobile version. Does he also pass it to AnkiHub too so they can earn from the app sales?

Ankihub is bunk. Why don’t they let us play Darbot games here?

Longtime anki user here. I think the thing people never appreciate with flashcards is that deck maintenance is real work. And in many cases, it's not work that you can do yourself as a learner of the material: the deck really needs to be created by someone who knows the material.

Commercial decks, where the deck maintainer is paid for his efforts, make a lot of sense.

And I suppose if they are making money out of the ecosystem, it also only makes sense that commercial deck makers make a contribution to the technology that makes it possible. I suppose I would prefer that be a contribution rather than ownership and custody, but I suppose Anki's license terms (it is AGPL3+ - I think without a CLA) prevents them closing it.

So cautiously optimistic

Spaced repetition seems like an ideal candidate for vibecoding. Sure, it gets complicated if you want all sorts of multimedia support, but for a lot of people, that's not necessary. How hard is it to build something like this, especially in 2026?

The way AnkiHub answers the questions in the FAQ in that non-answer corporate way sure gives me bad vibes.

One of the apps that should be worth billions of dollars and the founder billionaire

I have had a bad experience with Anki so far. Maybe someone can chime in, clearing things up for me:

When I search for HSK vocabulary Anki decks or whatever they call it, I found almost exclusively sets of words that are the wrong way around. They showed me the Chinese characters and asked me what the English translation is. I was incredulous about how many wrong decks there are and that I could not find good decks. I was starting to wonder, if people are actually just using Anki to learn to read Chinese characters, one-way learning basically, only recognition not writing. Only for reading subtitles and such, instead of writing with friends. Or perhaps they have the illusion, that they are able to write, because they can type in the Pinyin, and will get a selection of characters, which they then can recognize. But I, I want to be able to properly write the characters myself. The crucial issue was, that I did not find a simple setting to invert the direction of translation of a deck. How can such a simple thing not be among the most easy to find actions to perform with a deck? I read something about it not being possible on mobile phone, but somehow being possible on computer, but not as simple as flipping a switch.

Ultimately, I abandoned Anki and recently proceeded made my own tool for learning the characters, that is highly configurable and that can change the direction with the change of one config attribute.
