Foxi isn't trying to replace your textbooks, tutors, or Anki.

It's the missing layer between:

"I'm watching something."

and

"Wait... I actually learned something."

No grinding.
No mandatory lessons.
No motivational speeches.

Just watch something you enjoy, look up what you don't understand, and keep going.

🦊 Foxi Subs - study while entertaining.
