I still haven't quite understood how Anki can apparently be profitable when the web sync with Ankiweb apparently supports an unlimited amount of data (surely some people heavily abuse this - but one never hears about fair use being applied?). Even legit and honest use can mean massive collection sizes since you can have any rich media in an Anki collection.

There's no CLA on Anki. Even dae does not have the right to relicense it.

Can't help but wonder if it might not be time to start a FOSS alternative just in case Anki begins to decline.

It might not be the worst idea to do that anyway. Anki is great, but there's plenty of room for improvement. Off the top of my head, an architecture that doesn't involve fragile and finicky python bits and is designed to support multiple independent clients would be a nice step up (Telegram is a good model here — make a core lib with all the nuts and bolts which devs build clients around).

Mochi has really come a long way and has some wonderful built-in functionality. The automatic text-to-speech template options are high quality and randomize a variety of voices in each language. It's also doing some cool things with dynamic cards and LLMs.

Impressively, Mochi now offers FSRS (beta but still available in the app's main settings) and both the type of scheduler (Mochi default or FSRS) and the schedulers' settings are configurable on a deck-by-deck basis.

The developer is very responsive to folks on the forum and often quickly adds requested features.

Overall the app is well-designed and fun to use. I appreciate the swipe left/right to fail/pass cards on iOS. My one complaint is that the web clipper only works with Chrome and Firefox, but not with Safari (surprisingly). It would also be useful to have a global hotkey/palette to quick-add cards to various decks, similar to how OmniFocus lets you quickly add items to the OF Inbox.

I've been paying for the pro version for a while. It's templating is really powerful and easy to use. For my vocab deck, I set up a input field (e.g., word) and a bunch of derived fields (dict definition, AI-generated example, TTS audio). To add a new card, I just input the word and other fields will be automatically populated.

Technically this can be implemented in Anki as an addon. But only the desktop version supports addons and the default UI is a bit too complicated.

Looks nice but being an Electron-based app is a huge dealbreaker for me.

Can you import Anki decks and review history?

Ideal for Andrew, maybe. For the users? The jury is out.
