Phrasing looks amazing!

There's a lot of UX work to do for SRS. Do you have a sense of how well the ideas behind Humane SRS translate outside of language learning? I imagine the main challenge would be identifying a steady influx of new cards.

I agree that gains in scheduling accuracy are fairly imperceptible for most students. That's why, over the past few years building https://rember.com, we've focused on UX rather than memory models. People who review hundreds of card a day definitely feel the difference, doing 50 fewer reviews per day is liberating. And now that LLMs can generate decent-quality flashcards, people will build larger and larger collections, so scheduler improvements might suddenly become much more important.

Ultimately, though, the biggest advantages is freeing the SRS designer. I'm sure you've grappled with questions like "is the right unit the card, the note, the deck or something else entirely?" or "what happens to the review history if the student edits a card?". You have to consider how review UX, creation/editing flows, and card organization interact. Decoupling the scheduler from these concerns would help a ton.

I would say probably 50% of the learnings from Humane SRS would be applicable in other fields/schedulers. There is another half that is language-specific though - at the end of the day, if you try to learn a language the same way you cram for a med school exam, you're probably not going to succeed. The inverse is also true, please nobody use Phrasing to cram for their med school exam XD

I agree most peoples collections get unwieldy and something needs to be done, so props to Rember! I take the opposite approach - instead of helping people manage large collections, I try to help people get the most out of small collections. This sort of thing is not possible in most fields outside of languages (I don't think — I cannot say I've given it any real thought though).

For example, the standard tier in Phrasing is 40 new Expressions per month. This should result in 2,000-3,500 words in a year, which would be a pretty breakneck pace for most learners, and is considered sufficient for fluency. Of course, users can learn Expressions other users have created for free, or subscribe to higher tiers, or buy credits outright, but it's often not needed.

Indeed Phrasing does not really use the idea of "cards," we reconstruct pseudo-cards based on the morphemes, lemmas, and inflections found within the Expression. So "cards" are indeed not the boundary I use.
