Im looking for the application where I can learn new vocabulary in both mobile and web versions.
Writing mode is very required for me over one set and (or) over folder with multiple sets. Does Anki has this feature in paid apps or other ways to import huge amount of word-definition pairs?
Also Does Anki has a open API so that I can import easily numerous of words from my notes in csv or excel formats via http to Anki’s backend?
You don’t need an API or special mode or backend access to create your notes. You can import them directly into the Anki mobile or desktop apps with a properly formatted text/CSV file. Text Files - Anki Manual
Also it could be spelling mode. Write definitions not just taping on the screen. This mode focuses on testing the user’s ability to correctly spell the terms or answers associated with the flashcards. Here’s how spelling mode typically works in a flashcard application
I wrote about numerous words that is why I need an API. Thank you so much for the link!
