I've had premium subs with both and switched to Claude 3.5 Sonnet. I'm blown away by what it can do. Example for context:
I'm a software dabbler so I can do basic stuff with frameworks like Django, but I'm definitely not a developer by any stretch. My use case is to build mvps cheap and quickly to test out ideas.
Claude spit out a Django project that integrated Twilio for SMS functionality. What's _really_ amazing is that it also walked me through how to set up ngrok and Twilio so that I could use my computer as a temporary server. Again, I'm a dabbler so devops is completely over my head.
In maybe 2 hours I had a functioning prototype that I could interact with via SMS. I can't comment on the quality of the code or how viable this approach is for building in production, but to bring an idea to life so quickly with limited skills is really exciting.
> I haven't seen any of these tools doing anything that anki doesn't — why not contribute to it instead?
For the same reason that your area likely has more than 1 pizza restaurant. Other people want to take a stab at their own vision of a thing and that's awesome. Personally, I find Anki to be pretty uninviting to the general public.
Fluent-Forever.com is an example of an application of spaced time learning applied specifically to languages and their app is pretty great.
We may disagree philosophically, and that's ok, but I tend not to buy into the perspective that if X already exists and Y is like X then Y should not exist.
